Synology Surveillance Station Review: The Best DIY Security Cam System for a Cost

Share what you're reading!

If you have a Synology NAS server, you probably already know that there are many things you can do with it besides hosting backups and shared folders.

One of those is the ability to build your DIY IP-cam security system via the Synology Surveillance Station add-on package (or app). In my opinion, this feature is so useful and well-designed that it alone can be the reason you should get a Synology NAS in the first place.

This post will explain the Surveillance Station app and how to make the most out of it. Before continuing, check out my take on Synology NAS servers to get an overall idea of working with a Synology NAS server, including accessing its web user interface.

Dong’s note: I first published this review on May 20, 2019, with Surveillance Station 8.2 running under DSM 6.2, and updated it on May 30, 2022, to add more information with Surveillance Station 9.0 under DSM 7.1. Synology regularly pushes out minor updates for this app and others. The information in this post is from the latest version available by the published date.

Synology DSD1621 NAS 1
A Synology NAS server makes an excellent host for an advanced surveillance system via the Synology Surveillance Station add-on app.

What is the Synology Surveillance Station?

There are many options on the market for home security surveillance. Most of them are exclusive: once you’ve picked a vendor, you’re stuck with it.

For example, you can’t use something like the Soliom Bird S60 with an Arlo setup. I’d recommend neither, so don’t try, but the idea of mixing hardware of different vendors is where Synology Surveillance Station beats every brand. It’s a standard network video recorder (NVR).

Synology Surveillance: A versatile NVR add-on app (package)

Surveillance Station is one of many Synology add-on apps, or packages, available in any NAS server’s Package Center.

Once installed and activated, the app turns the server into a digital video recorder for network cameras.

The apps allow you to manage multiple IP cameras at a remarkably comprehensive level and save security footage directly on your NAS server. That’s on top of the options to use the camera’s built-in SD card slot or the vendor’s cloud.

Synology introduced the Surveillance Station in March 2008 and has improved it regularly.

Synology Surviellance Station 9.0 vs 8.2

In early May 2022, Synology updated the app from version 8.2 — which has remained largely the same since first released in September 2018 — to version 9.0 with some improvements.

Synology Surveillance Station 9.0Synology Surveillance Station
The Synology Surveillance Sation 9.0 (left) vs 8.2: Both have an excellent user interface, similar to a native operating system. Among other things, you can run multiple windows at a time.

Details of the new version are in the release notes below.

  • The recordings of the services will no longer be shown in File Station by category (still available for downloaded in Surveillance Station).
  • The cameras will apply the highest archive setting and stream profile value available for the services.
  1. Privacy Masking and watermarks are not supported on Android DS cam 3.5.1/iOS DS cam 5.4.1 and before.

But the key takeaways of the new version are in the following bullet points:

  • C2 Surveillance (*): Users can choose to upload footage directly to a Synology C2 cloud server which opens up a lot of possibilities:
    • Managing multiple locations in a single app.
    • Quickly share the footage with third parties.
    • Protecting security footage in case of fire or thief.
  • Maps integration: Each camera can be pinned to a precise location on a world map for easy management.
  • Monitor Center: A more streamlined user interface that combines Live View and Timeline of version 8.2 into a single intuitive app.

(*) A C2 Surveillance subscription is required after a 6-month trial.

It’s worth noting that Surveillance Station 9.0 require DSM 7.0 or later. Consequently, Surveillance Station 8.2 will remain relevant to existing servers that still run DSM 6.

And you can keep using version 8.2 on DSM 7 if you choose to do so.

Surveillance Station 8.2 to 9.0 upgrade: A straightforward process

I upgraded my system from version 8.2 to 9.0, and the process was easy — I had to agree with a warning, shown below, and after about 10 minutes, the migration finished without a hitch. All of the existing recordings remained in place.

Surveillance Station 9.0 Update Notes
The warning you’d get when upgrading to Surveillance Station 9.0 from 8.2.

The two versions share mostly the same user interface, customizations, hardware support, and add-on apps.

I’ve used version 9.0 for a few weeks, and unless you’re interested in C2 Surveillance, it’s practically the same as version 8.2 — it mostly makes things easier and requires a bit of getting used to here and there.

Surveillance Station: A standalone platform

Yes, you read that right. Surveillance Station, itself an add-on package, is also a platform that can run other security-related apps to expand its features and functionality.

Indeed, it has its own user interface, similar to but separate from the NAS server’s OS (DSM), with a taskbar, a desktop, etc. You can run multiple windows at a time.

Synology Surveillance Station Apps 9.0Synology Surveillance Station Apps
The Synology Surveillance Station has many add-on functions via the Application Center. Version 9.0 (left) and 8.2 practically share the same apps.

No matter which version you use, here are a few things that make Synology Surveillance Station so much better than other canned home security camera solutions:

  • You have complete control over the recording — there’s no need to fret about your privacy.
  • Unless you opt for C2 storage, there’s no monthly fee, even when you want to have very long video retention. The more storage your server has, which you can easily upgrade, the longer you can keep the footage.
  • You have the freedom to mix-matching cameras that fit your needs — crucial when using different indoor, outdoor, Wi-Fi, Ethernet, and PoE cameras together.
  • It’s Internet-agnostic. Your system is still running on local storage even when your broadband connection is unavailable. Also, you won’t need to worry about data usage, except when you view live or recorded footage when you’re not at home or when you use C2 recording.
  • You can set up the system to stay alive even when there’s a power outage by using PoE cameras together with a high-capacity UPS.
  • You can use the web interface, the Synology Surveillance Station desktop application, or the DS Cam mobile app to manage your camera system, locally or on the go.

And the Surveillance Station will give you a lot more since it has lots of features, including the ability to manage our system via the Internet. You’ll get everything you’d expect from a professional surveillance system from this app.

Amcrest IP Surveillance Cam for Synology
Amcrest is one of many vendors whose cameras work well with the Synology Surveillance Station. I’ve used this particular unit for more than two years.

Surveillance Station: Excellent user interface

As mentioned above, the Surveillance Station has an intuitive user interface of its own. Each major function of the surveillance system is managed via an app with shortcuts readily available on the desktop.

They include:

Live View (version 8.2-only): Allow you to view live footage of all cameras and perform any live actions with them. The live view doesn’t affect the recording. In other words, a camera still records (based on your settings) when you’re viewing its live feed.

Timeline (version 8.2-only): View recordings of previous days in a 24-hour timeframe. There’s also a neat search function to find videos of objects based on motions at a particular part of a camera’s view.

Monitor Center (version 9.0-only): A new app that combines Live View and Timeline with a more streamlined design — users can get more done with fewer clicks.

IP Camera: This allows you to add cameras to the Surveillance Station and customize their settings.

Recordings: View recordings of individual cameras. You can download a recording or export multiple recordings based on different parameters.

Application Center: Allow access to a list of tens of other functions and apps to add even more features to the Surveillance Station. There are links to download the Surveillance Station desktop and mobile apps that you can use instead of the web user interface.

Similar to the server’s interface, the Surveillance Station’s interface can handle multiple windows. For example, you can run Monitor Center in the background and IP Camera in the foreground simultaneously.

Synology Surveillance Station Timeline 9.0Synology Surveillance Station Timeline setup
With Surveillance Station 9.0 (left,) the Timeline app is now part of the new Monitor Center. Note the differences in the previous version.

This type of user interface makes working with the system self-explanatory and intuitive. If you’re family with an operating system, you find yourself at home with Surveillance Station.

What cameras does the Synology Surveillance Station support?

Synology’s Surveillance Station supports thousands of IP cameras on the market. Here’s the complete list.

It’s important to note that even those not (yet) added to the list will work with Surveillance Station as long as they support ONVIF — an open set of standardized interfaces available in most IP cameras.

Case in point: I used two Amcrest IP2M-852W cameras, not yet on the support list at the time I first published this piece, and they worked flawlessly for years before I replaced them — they became obsolete shortly after being officially supported by Synology.

Generally, if a camera has a web interface, it will likely work with the Surveillance Station app. On top of that, you can even turn an old Android phone into a camera.

You can also expect camera support at the vendor level. If you find a camera from a particular vendor that works with the app, other cameras from the same vendor will likely work, too.

That’s except for solar-powered cameras. For now, all solar cameras are not compatible with Synology Surveillance Station. These cams generally do not have enough power to support ONVIF. So all solar-powered cams require their proprietary NVR.

In my experience, there are just a handful of security camera vendors whose cameras won’t work, including those from Arlo, Google, and, Ubiquiti and Amazon.

When a camera is supported, most, if not all, of its functions and features will be available to the app. For example, if the camera has pan and tilt functions, the app can control those. For all cameras, all essential features, including zoom, night vision, and motion detection, are all there.

Synology Surveillance Station 9.0 New Web User Interface
By default, Synology Surveillance Station 9.0’s web user interface has a dark theme. Note the new Monitor Center and Maps icons.

How many cameras can I use with my Synology NAS?

The total number of cameras depends on the NAS server, but generally, each server can handle a dozen or more cameras — more than a home would need.

The DS218+, for example, can support up to 25 cameras. Larger servers, like the DS1019+ or DS1621+, support many more simultaneously.

So, you won’t need to worry about having too many cameras.

Synology Surveillance Station: Straightforward setup

Setting up a camera with the Synology Surveillance Station is not exactly hard, but it’s more work than other canned solutions, like the Arlo.

That’s because it’s a two-step process, with each being potentially involved depending on the camera you use. You first need to connect the camera to your network, and only then can you add it to the Surveillance Station.

Connect an IP camera to your local network

Hooking a camera in your system is a standard procedure.

If it’s a wired camera, plug it in via a network cable, and that’s it. For a Wi-Fi camera, you’ll need to follow the camera’s manual to connect it to the Wi-Fi network using its web interface or mobile app.

After that, follow the camera’s instructions to change its basic settings to fit your situation. Examples of these generic tasks include:

  • Set up the user name and password for the camera access. Make sure you use a secure password and remember it — you’ll need this information for the next step.
  • Adjust time zone and locale.
  • Customize the camera’s video quality — there’s no reason not to use the highest settings — timestamp display, logo display, etc.
  • Update the camera to the latest firmware.
  • Reserve an IP address for each camera. This is an important step. You don’t want its local IP address to change, which will cause disconnections, and find out its port. Most cameras use ports 80, 88, or 888, and you can also set the port to a value of your liking. Whichever you pick, note that down — you’ll need each camera’s IP address and port number for the next step.
  • Mount the camera where you want them to be.

And that’s it. Now you’re ready to hook the camera to your NAS server’s Surveillance Station.

Set a camera up with Synology Surveillance Station

This step is when you hook a camera connected to your home network to the Synology Surveillance Station. It’s pretty straightforward. Here are the general steps.

  1. Open the IP Camera icon, which will open up the window. Here, you’ll see all existing cameras (if any).
  2. Click on Add. If you use version 9.0, the system will automatically detect the available camera. In version 8.2, you’ll need to click on the magnifying glass to start detection. But in any case, you can pick the detected cam or enter the cam’s information manually — with the information noted in the above step.
  3. For a manual setup, you can enter the brand and model of the camera if it’s on the supported list or pick [ONVIF] if your camera support ONVIF and is not yet on the list.
  4. Click on Test Connection to make sure your camera is connected — you’ll see a preview of the camera’s view.
  5. Click on Finish.

And that’s it; the camera is now part of the system. But you’ll need to customize its settings to your liking first.

Synology Surveillance Station Setup 9.0Synology Surveillance Station Setup
The Synology Surveillance Sation 9.0 (left) vs 8.2: No matter which version you use, setting up a camera with the Synology Surveillance Station is straightforward. It’s more so with version 9.0.

Lots of settings, highly customizable

To customize a camera’s setting, call up the IP Camera icon again, select the camera on the list, and click Edit. Surveillance Station has a lot of settings and customization in five categories, including the following:

Device settings: Change general camera settings, including video compression format (h.264, MJPEg, and so on), video quality (resolution, frame rates, image quality, and so on), or pick an external speaker as the audio output for the cam (if supported).

Recording Settings: All recording-related settings are here, including storage space and video retention options, scheduling (when to record based on motion detection, when to record continuously, and so on), and mapping recording (motion detection or continuous) with a stream profile. You can also set the length of each video from 1 to 240 minutes.

Live View Settings: The stream profiles determine the video quality for live streaming.

Optimization: Miscellaneous settings, such as timestamp onscreen display, camera orientation (flipped, mirror), time synchronization, etc.

Event Detection: Set motion detection source (by the camera or by Surveillance Station), sensitivity (from 1 to 99, the higher, the more sensitive motion detection is), and threshold (from 1 to 99 as the size of the object that can trigger detection.) You can also change detection areas to ignore certain parts of the camera’s view.

It’s important to note that the amount of customization varies depending on the camera. Version 9.0 has a function where you can quickly copy the setting of an existing camera to a newly added one, making the setup process much faster.

In all, Surveillance Station has a lot of settings to fit anyone’s recording needs. And again, there are also even more available via the Application Center.

Synology Surveillance Station: Excellent performance

I’ve used Synology NAS servers for more than ten years and have used Surveillance 8.2 since late 2018 until a few weeks ago before upgrading to version 9.0.

I’ve been happy with how the app works for the most part. It’s reliable and delivers excellent performance.

Compared with other canned security camera systems, like the Arlo, the best thing about Surveillance Sation is that there’s almost no limit to how long a recording can be.

The Timeline view and Sync playback (now available with improved performance vis Monitor Center in version 9.0) are also helpful when I need to find a particular recording or have a good picture of what’s happening at a specific time.

Remote access to the system is also convenient. You can do that via the web interface, the Surveillance Station desktop software, or the DS Cam mobile app. They all use Synology’s QuickConnect vendor-assisted portal to access the NAS server. Alternatively, you can also use Dynamic DNS.

Using remote access with the Surveillance Station means you stream recording (or live footage) from the NAS server. For this reason, the performance depends on the Internet speeds at both ends, where the NAS server resides and the remote location.

(By the way, this is one of many reasons I appreciate my new Fiber-optic line with stellar upload speed.)

Synology Surveillance Station Mobile App
The DS Cam app remains essentially the same when working with Surveillance Station 9.0 or version 8.2. It’s an excellent way to manage the Synology Surveillance Station remotely.

It’s worth noting that the Surveillance Station doesn’t take a lot of system resources.

Over the years, I’ve used this app with more than a dozen of  Synology NAS models — DS410, DS411slim, DS1511+, DS412+, DS712+, DS713+, DS1513+, DS214play, DS214se, DS414slim, DS415+, DS1515+, DS1517+, DS218+, DS1618+, and DS1019+, DS419slim, DS220+, DS1621+ — and none of them had any issue.

For example, the DS1618+ server, which has 8GB of RAM (default) and no other upgrades, ran my four-camera Surveillance Station app smoothly with a few other heavy apps, including a Windows Server 2016 virtual machine.

The more cameras you use, the more the NAS server has to work. However, my take is if you employ five or fewer cameras — I’ve always used only four at a time — it’s safe to say you won’t need to worry about the server being slowed down.


Like everything else, the Synology Surveillance Station is not perfect. Here are a few things that you should be aware of:

Camera license

Each Synology NAS server includes only two camera licenses, no matter how big or expensive.

If you want to use more cameras, you’ll need to buy additional licenses at about $60/each. I feel the company should include a free license per drive bay. So a 4-bay server should have four free camera licenses and so on.

By the way, you can transfer a purchased license from one server to another. Just delete it from a server, and it will become available to use with another. However, the two built-in licenses will remain with the server even when you don’t want to use them.

Too many settings, impractical default (version 8.2-only)

In my experience, if you use the default settings with version 8.2, one or all of these will happen:

  • No motion detection recording
  • Video quality automatically set to the lowest
  • Short video retention.

Version 9.0 has some improvement on this front, but it’s a good idea to take your time and configure each camera properly. If you use multiple similar (or the same) cameras, you can make batch changes to all of them simultaneously.

No support for internet-based or solar-powered cameras

A Surveillance Station can only host local cameras — it can’t directly host cameras at multiple locations via the Internet, like in the case of Arlo.

The newly added C2 Surveillance feature helps bring multiple locations together, but you still need a separate NAS server (or a dedicated Surveillance Station NVR) at each location. On top of that, the subscription can be cost-prohibitive.

As mentioned above, no solar camera works with Surveillance Station. While this is not exactly Synology’s fault, it does limit your options.

Synology Surveillance Station's Rating

Design and Setup
8.5 out of 10

Lots of recording features and settings

Supporting thousands of IP cameras on the market

Highly customizable

Excellent interface and remote management

Version 9.0 adds free Integrated Maps and C2 Surveillance (subscription required).


Only two camera licenses are included with a server

Require networking know-how for setup and management

No direct management for off-site cameras without additional NAS servers or DVRs at the remote locations; no free C2 Surveillance tier

No solar-powered cam option


Like a Synology NAS server, the Surveillance Station is not for everyone. It requires certain networking know-how to perform the setup and ongoing management.

However, in return, this do-it-yourself surveillance system is much more comprehensive than any other canned home security camera set. Among other things, it gives you complete control of your security recording without a monthly subscription.

Surveillance Station 9.0 brings in new features, but it’s its better ease of you that’s most welcome. The C2 Surveillance support is just too expensive to be useful.

In any case, if you already have a Synology NAS, get one or two cameras and try out this add-on app. You won’t be disappointed.

And if you have a large, well-connected property, a sizable Synology NAS will work much better as an advanced security system than many services. It might cost more upfront, but you’ll save a lot in the long run, especially considering other networking needs the server can fulfill at the time time.

  1. Hi, Dong,

    Companies like Amcrest, also offer these packages of four cameras and an NVR. Would you recommend simply purchasing the camera from Amcrest and going with the Synergy NAS?

    • I’d recommend using the cams with your Synology server, Brad. It’s a light year ahead of any proprietary NVR, plus you can do many other things with the server. But either will work.

  2. Hi Dong,
    I just updated my Synology Surveillance station from V8.2 to V9 and just after it started I panicked as I recalled you had mentioned some issue. On checking your article it was the fact it didn’t work pre DSM V7 while I have V6.2.4 oops!
    Fortunately Synology wins and it now works on anything Post V6.2.4

  3. Dong,

    to clarify,
    In the surveillance station desktop client there is a bookmark button that will bookmark points in videos that you can find and look at easier after. In the DS cam app I cannot find the bookmark button or it simply doesnt exist. I was just asking from your experience if you know if it is there or not. Dont assume I have not used or tried the product based on my post. I am just asking for your help. Dong Knows Tech should be able to help. Otherwise what’s the point of this blog.

    • The point of this blog is so that I don’t have to answer every question INDIVIDUALLY, Jimmy, and I’m definitely not here for you specifically. If you see something, it’s safe to assume it’s there. If you don’t and can’t find it, it’s also safe to assume that it’s not there. Generally, mobile apps are not as comprehensive as desktop apps (or web interfaces.) What part of “figuring things out” did you not understand?

      My previous reply was based on your previous questions, which indicated that you hadn’t spent time reading my previous replies or putting two and two together. The point is this: I don’t mind helping, but I can’t re-digest every bit of basic information and then spoon-feed it to everyone who feels entitled to get things the easiest way. It would help if you did your homework before asking questions. You’re welcome to ask them elsewhere going forward.

    • @Jimmy

      I read your previous convo with Dong below. You’re such a stupid idiot and that has nothing to do with tech. Use your brain for a change. Think. Don’t just ask every question that pops into your head like a child and waste everyone’s time.

  4. I would like to set up dual recording like this.

    Primary surveillance drive 24/7 recordings. Secondary drive or different folder only motion recording.

    Is there a way to do this automatically in surveillance station?

    • Yes, Jimmy. You’ll be asked to use which shared folder (on which volume — this is part of how you set up a NAS server) to store the footage and you can add as many folders as you want and use them for whichever camera you want. But one camera can record to only one folder. You can always change that using the Storage “app” of Surveillance Station.

      • to clarify,

        Id like the same footage from 1 camera,
        one drive to store 24/7 recordings
        other drive to only save the motion detection events from the same footage.

        is this possible?

        • You can’t do emotion detection AND 24/7 recording on the same cam, Jimmy. The latter cancels out the former. But the short answer is a big NOPE. As mentioned in my previous reply, one camera can record to only one folder at a time. Go figure!

          • thanks,

            different question,

            is there a bookmark feature on the ds cam app? i cant seem to locate it

          • I have no idea what you mean by “bookmark feature.” I’d recommend using the app and figuring things out or checking with the manual. Don’t apply what you know from previous experience to a new product mechanically. Also, a bit of deductive reasoning would help. Please do that before asking more questions.

  5. I have a NAS at one house but have cameras at two houses. Only one NAS (a vanilla 718+) at the main house.

    The first is connected locally, as usual, on a 192.168.x.x IP address.

    The second is connected over the internet. I point Surveillance Station at and use port forwarding on the router at the second house to send the traffic to the camera on its local IP address. Could add more cameras using different ports if needed. It all works fine but, does use up a couple of Mb/sec of bandwidth per camera.

    I use a dynamic DNS provider as my ISP gives me a dynamic IP address but you could even do the same with the help of Tailscale (an easy to set-up VPN, which is available on the Synology) if you were stuck behind CGNAT.

      • OK, its just that under “Cons” you mentioned:

        “Only works with cameras in a local network, and an expensive C2 Surveillance subscription is required for multi-site support”

        We manage multiple sites from a single location using CMS and find it extremely useful. Just thought it was worth a mention πŸ™‚

        • CMS doesn’t turn a server into a DVR of an off-site camera, David. For example, if you have a camera in New York and your NAS is in San Francisco, there’s no way to make that camera record to the server. CMS is only an alternative way to view multiple servers at multiple locations in one place. But that can be done manually (without CMS).

          C2 is much easier than CMS; I didn’t say it was the only way. But you got a point there. I updated the review without re-doing the Pros and Cons organically. I edited the text to clarify my point: there’s no cheap way to make that happen. I tried.

          Thanks for the input!

  6. Thank you Dong for this great article. In terms of securing the surveillance system, have you written anything about segregating all IP Cameras to a secondary network and away from the main home network?

    • That has nothing to do with securing the system, Angelo, and will certainly cause the cameras to stop working if the server is within the main network. More in this post about Guest networking. You might have read too many of those articles on “security”. πŸ™‚

  7. Hi, Dong – thank you for this article!

    Am I correct in assuming that while using the Synology NAS as an NVR, I can also use it at the same time for other purposes (e.g., data backup and photograph repository)?

  8. Just two camera licenses per NAS isn’t enough to interest me to set up as an experiment. Also, the cost of four cameras plus two licenses is enough to buy an eight channel NVR with four cameras from other vendors.

    • You’re correct, Jennifer, cost-wise, and that’s also my biggest complaint. But usability has its value, too. I know many who only buy cams that are supported by Synology NAS. Also, you can move the purchased licenses from one NAS to another.

  9. Hi,

    You mentioned the below :
    You cannot use a single NAS server to host cameras at multiple locations, like your home and your office β€” you’ll need a NAS server at each address.

    But I note at :
    that it says you can connect remote cameras to the NVR/NAS by using port forwarding. I got a DS1019+ at home with about 10 TB spare capacity and am thinking of having a few cameras (couple of 4ks and maybe another 3 or 4 FHD) which are going to be placed remotely being recorded by my home NAS.

    Do you think this should work? (1gbps symmetrical connection at NAS location, at least 100mbps symmetrical connection at camera location).

  10. Hi Dong
    Most impressed with your description, very helpful
    I have set up my 218+ (Raid1) with ds surveillance and it uses about 1Tb for 30 days recording.
    I have my old ds213 (2x4TB drives) that I am going to use for backups of everything – total usage including surveillance is about 2tb. I intend changing raid to jbod or basic
    It’s debatable if I need backup of surveillance recordings, and not more than 30days worth, probably only 17 days worth.
    From you experience what backup configuration would you suggest from a practical point of view

  11. Hi Dong,

    Thanks for your review. I’d like to use a Synology for only running Surveillance Station with three 8MP / 4K IP cams on a separate network.

    I am looking to find a model that is powerful enough to get smooth streaming for live view from all three cams simultaneously. Since it is 8MP steaming I guess that CPU requirement would be more of an issue for this use case.

    Which model(s) would you suggest looking into from CPU standpoint? Diskwise I am thinking of setting up RAID0 (accepting the zero fault tolerance) but getting better R/W performance. I do not need 4 bays really, could do with 2.

    Love to hear your unsalted opinion. πŸ™‚

    • Any Plus (+) or higher-end model can handle that easily, Ed. If you want to make sure:

      1. Use SSD as the server’s storage. (This is not a must).
      2. Use network cables (PoE) for your camera. (This is a sure way since Wi-Fi can be temperamental.)

      Good luck!

  12. Hello Dong. Thank you for nice review. I have been recommended to look into Synology for my private surveillance system. I just have some questions about Synology:
    1: Buying licenses for more cameras, is it a one time cost?
    2: I was thinking of buying a NAS, what more do I need to be able to watch my property when I’m not at home? I also want to control my PTZ camera remotely from my I-phone.
    3: I’m new to this, so a detailed (not so expensive) list of models and software would be nice to get from you.

    • Hi Garry,

      1. Yes
      2. Nothing else. You use the free apps of Synology.
      3. This review and related post (linked within) are all you need and what I can provide.

  13. Hello Dong. Thank you for nice review. Would you know answers to some of these questions:

    1. Can an older ARM-based DS214 support 7x 2MP cameras? In specs I see max # of cameras 12, but I am skeptical given the weak dual-core ARM CPU.
    2. What kind of load is Surveillance Station (SS) putting on CPU?
    3. The Dahua IPC-HDW5241TM-AS cameras I intend to use with my DS214, do not have a profile in SS. Should I use ONVIF profile or Dahua_Generic profile?
    4. What are the pros and cons of ONVIF vs Dahua_Generic profile?

    Thank you.

    • Hi Peter,

      1. Yes, totally.
      2. Not a huge amount. The stress is mostly on the drives. The more cams you have, the more concurrent write might take place. But as a rule, you shouldn’t expect to use all of the server’s apps at their max. So if you just use it for cams, it’s fine to max out the supported number. Generally, I’ve never had a problem with cams, including ith low-end servers. The issue is when you playback, in that case, a faster server will help with the delay.
      3. If the cam support ONVIF, it’ll work, at least as a generic cam. You might NOT be able to access all of its features (pan/tilt/zoom) etc., though.
      4. See #3 again and this depends on the particular cam or vendor.

      • Thank you. One more question came to my mind. If a mobile device running DS Cam is used for Live View, is mobile CPU utilized to render the Live View? Or NAS CPU is doing the work? Would a cheap Android tablet be capable of displaying Live View from 7 cameras?
        And if DS Cam is used to play recordings, who is decoding them – NAS CPU or mobile CPU. Thank you.

        • You should have numbered your questions so it’s easier for me to address them. And these are multiple questions, not one.

          Generally, both parties are always involved to a certain extent. As for “cheap” Android, you shouldn’t use one, the issues with running an app would be the least of your problem. The server takes care of the encoding, but the phone needs to render them and that takes power. In short, things are a matter of degrees. There’s nothing black or white like the way you ask your questions.

          • Thank you very much. Yes, by ‘cheap’ Android tablet I meant relatively cheap, which would be used like a single purpose device. Only thing it would do is to run DS Cam.
            You are right about the black or white, my bad. I just wanted to know which device is mostly burdened in those scenarios. I guess I will use SS once I have the cameras and test it.

    • By default, it’s a notification on your phone, Borho, just like any notification. But you can customize it to be anything, text, email message, push, etc. and choose to send plain text, an image, or a 5-second snapshot. There are many other customization settings for this.

  14. Ok, I solved the multiple notifications problem. Notifications -> Advanced -> Notification Combination Setting.

  15. Thanks for the quick response! I’ll look more into how feasible a wired backhaul will be. A wired connection to the NAS will be easy as my broadband connection is upstairs (top level) in the office where the NAS will be. And I’ll def check out the other benefits of having the NAS server! Thanks again!

  16. Hey Dong, really appreciate all the information you share on your site!

    I’m looking to upgrade my home wifi network (3 levels/3400 sqft) and am curious as to your opinion of using the Synology Surveillance Station compared to the “canned” ring or nest options?

    Ideally I’d like to set up a mesh wifi network and if I go with a DIY security system then I think I’m leaning toward the Synology RT2600ac as the router, the MR2200ac as the satellite, and the DS218+. Do you think this would be a good configuration? Or would you suggest something different or more forward compatible like a WiFi 6 setup? Alternatively, I could forego the NAS server and get a canned surveillance system down the road. If I do that, would you say the synology router/satellite combo is still a great option? Just want to be most efficient with my resources and also don’t want to upgrade and then have to upgrade again in a year or two. Thanks in advance!

    • Thanks, Matt.

      That’s a great configuration. The Synology mesh you mentioned will work with anything. If you can use wired backhaul, you can ignore Wi-Fi 6 (for many years), if you can’t, it’s still good for a long time.

      The DS218+ is good for many things, surveillance is just one of them. You should definitely try the Download Station (and its DS Get companion mobile app). Also, make sure the NAS connects to the router via a network cable.

      A canned system like Nest sure is much more user-friendly, in exchange, it collects your information and might incur a monthly cost. So, it’s your call.


  17. Synology needs to add a snooze setting for motion detection. If there is a prolonged motion event, I’ll get multiple annoying notifications; I only need the first one.

  18. First off thank you for this article. I have a DS and two cameras at my house and have had issues with the cameras disconnecting. After reading your article I was reminded that I never set a static IP address for the DS and cameras. For the last few months I have ignored the cameras being disconnected. I just reconnected my cameras with static IP addresses. They are up and running and I hope that by changing the IP address to static will solve my the issues that I have been plagued with. Thanks again!
