For years, I’ve wrestled with getting more than just two cameras to play nice with my Synology Surveillance Station. It’s a dance of firmware, IP conflicts, and that special brand of frustration that only comes from proprietary tech that feels designed to make you pay more for the privilege of using more than the bare minimum.
Honestly, if you’re staring at your Synology NAS and wondering how to get total 4 camera working on Synology, you’ve probably already hit a wall. I certainly did, after spending nearly $300 on what I thought was a universal camera compatibility list that turned out to be… aspirational, at best.
This isn’t about buying the most expensive, proprietary camera system. It’s about making what you have work, or making smart choices if you haven’t bought yet. Let’s cut through the marketing fluff.
The Great Camera Count Caper
So, you’ve got your shiny Synology NAS, probably a DS220+ or a DS720+, and you’re thinking, ‘Four cameras sounds reasonable.’ Then you start adding them in Surveillance Station, and Bam! Error message. ‘License exceeded.’ Or worse, the camera just won’t connect, showing a generic ‘connection failed’ that could mean anything from a typo in the IP address to your camera deciding it’s on strike.
This is where most people start Googling, and frankly, the advice out there can be a confusing mess. Some sites tell you to just buy more licenses (which is true, but feels like a toll booth on a road you already paid for), others point to obscure ONVIF profiles, and a few just tell you to give up and buy cameras specifically listed as ‘Synology-approved.’ I found myself staring at my fourth camera, a perfectly good Reolink RLC-810A, after successfully setting up two cheap Amcrest bullet cams, and the NAS just gave me the silent treatment. No amount of port forwarding or fiddling with the camera’s internal settings seemed to help. It was maddeningly opaque.
My first attempt involved hours of scouring forums. I ended up disabling a bunch of advanced features on the camera, lowering the resolution to something I didn’t want, and trying about seven different connection methods. Nothing. It felt like trying to plug a USB-C into a micro-USB port and expecting it to work. The hardware was there, the network was there, but the digital handshake just wasn’t happening. This led me down a rabbit hole of RTSP streams and generic ONVIF settings, which, while sometimes useful, often feels like speaking a foreign language when the manufacturer’s documentation is about as helpful as a screen door on a submarine.
The core issue, beyond the obvious license limit, is compatibility. Synology’s Surveillance Station works by talking to cameras using specific protocols. While ONVIF (Open Network Video Interface Forum) is supposed to standardize this, the reality is a bit like the Wild West. Different manufacturers implement ONVIF in slightly different ways. Some cameras are plug-and-play, others require you to poke and prod at settings until you achieve a state of Zen, or give up and buy a different model.
The License Lie (and Truth)
Let’s address the elephant in the room: licenses. Your Synology NAS comes with two free camera licenses. That’s it. If you want to add more cameras, you need to buy additional licenses from Synology. Period. There’s no magic hack around this fundamental limitation if you want to officially add them through Surveillance Station. These licenses aren’t tied to the camera model itself, but to the NAS unit. So, if you buy four licenses for one NAS, they work on that NAS. If you buy a new NAS, you’ll likely need to buy licenses for that one too, unless it comes with more built-in. (See Also: How To Reset Zosi Camera System )
Buying these licenses is the most straightforward, albeit costly, way to get total 4 camera working on Synology. You go to the Synology Package Center, find the Surveillance Station add-on, and there’s an option to purchase licenses. They’re usually around $40-$50 each. For four cameras, that’s an extra $80-$100 on top of your NAS and camera costs. It stings, but it’s the officially sanctioned route.
Now, before you throw your hands up in despair about the cost, consider this: the price is somewhat justified by the integration. When you use Synology licenses, the cameras are managed through the Synology interface, updates are handled via the NAS, and you get access to all the features Surveillance Station offers, like motion detection zones, recording schedules, and remote viewing through the DS cam app. It’s a cohesive system, and sometimes, paying for that cohesion is worth it.
However, and this is where my personal frustration often flares up, is when a perfectly good camera *should* work but doesn’t, or requires a workaround that feels like a hack. It’s like having a gourmet kitchen but being told you can only use two of your fancy knives because the landlord only provided you with two slots in the magnetic strip. The other knives are perfectly good, they just don’t fit the pre-arranged system.
The Onvif Gauntlet: When Marketing Meets Reality
Okay, so you’ve bought your licenses, or you’re determined to make that fourth camera work without one (which, by the way, is generally not recommended for reliable, integrated use within Surveillance Station itself, but some users explore network tricks for specific DIY monitoring). For those of you who *have* the licenses and are still hitting walls, the ONVIF protocol is your next frontier. ONVIF is an industry standard that allows IP-based security products to communicate with each other, regardless of brand. It’s supposed to be the great equalizer.
Here’s the rub: not all ONVIF implementations are created equal. A camera might claim ONVIF compliance, but if Synology’s Surveillance Station is looking for Profile S, and the camera only offers Profile G or a slightly modified Profile T, you’re SOL. It’s like two people speaking different dialects of the same language – they might understand the gist, but the nuances get lost, and sometimes, they just can’t hold a conversation.
When adding a camera that isn’t on Synology’s official compatibility list (which, by the way, is a good starting point but not gospel), you typically choose ‘Manual Setup’ in Surveillance Station. You’ll need the camera’s IP address, its username and password, and crucially, the RTSP (Real-Time Streaming Protocol) URL. Finding the correct RTSP URL is often the trickiest part. It’s usually something like rtsp://username:password@IP_address:port/stream_path. You can often find this in the camera’s own web interface or by searching online for “[Camera Brand] [Model] RTSP URL”.
Once you have the RTSP URL, you input it into Surveillance Station. If it connects, great! If not, you might need to try different ONVIF profiles or connection types. Some cameras allow you to specify the ONVIF profile in their own settings. I spent around three hours one Saturday trying to get a Hikvision camera to connect to my Synology NAS, fiddling with every ONVIF setting I could find on both ends. It was a deeply frustrating exercise that involved more coffee than I care to admit. (See Also: How To Set Up Trace Camera )
A key step here is to ensure your camera is set to the correct network settings. Static IP addresses are your friend. Trying to manage cameras with DHCP can lead to IP conflicts or the camera losing its address and disconnecting from the NAS. Assigning a static IP to each camera within your router’s DHCP reservation list, or directly on the camera itself, is a best practice that many people overlook. This means the camera *always* has the same IP address, preventing the NAS from losing track of it.
The Sneaky Workaround (use with Caution)
Alright, let’s talk about the slightly less official route. I’ve seen discussions and some people claim success with using generic ONVIF drivers or specific third-party integrations that can sometimes get a camera working even if it’s not perfectly recognized by Surveillance Station. This usually involves digging into the camera’s firmware or using tools outside of Synology’s ecosystem to broadcast the stream in a format that Synology *can* understand.
One common method involves setting up a secondary NVR or even a basic media server (like VLC or FFmpeg running on a separate PC or even a Raspberry Pi) that can ingest the stream from your problematic camera and then re-stream it in a format that Surveillance Station recognizes. This adds complexity, potential points of failure, and can introduce latency. It’s like adding a translator between two people who don’t speak the same language – it works, but it’s clunky and one person’s voice might sound slightly distorted.
However, this method often bypasses the Synology license requirement for *that specific camera stream* if you’re just pulling the stream into another application, not directly into Surveillance Station as a managed camera. But if your goal is total 4 camera working on Synology *within the Surveillance Station interface*, with all its features and management, this is a roundabout way that doesn’t quite get you there. You’re essentially tricking the system, or rather, building your own bridge. It can be done, and I’ve seen it work for basic recording, but it lacks the polish and stability of a native integration.
For my part, after my third unsupported camera adventure, I just bit the bullet and bought the Synology licenses. The headache it saved me, the stability it provided, and the ease of management with the DS cam app made the extra $50 feel less like a rip-off and more like a necessary investment in sanity. It’s about the total cost of ownership, not just the sticker price of the hardware. When you factor in time spent troubleshooting, potential data loss from unstable connections, and the sheer mental drain, those licenses start to look pretty reasonable.
Consider the official Synology compatibility list your first port of call. If your camera is on it, you’re usually golden. If it’s not, prepare for a bit of a technical scavenger hunt. Forgetting to enable the correct ONVIF profile on the camera side is probably the most common reason a camera won’t connect, even with the right license and RTSP URL. It’s like having a key but forgetting which lock it fits.
Why Does My Camera Show as Unsupported in Synology Surveillance Station?
Cameras can be unsupported for several reasons. Primarily, they might not be on Synology’s official compatibility list, meaning they haven’t been tested and verified to work seamlessly. Even if a camera claims ONVIF compliance, specific implementations can differ, leading to connection issues. Ensure you’re using the correct connection type (ONVIF, Generic RTSP) and have entered the correct RTSP URL if applicable. Sometimes, a firmware update for either the camera or Synology Surveillance Station can resolve compatibility issues. (See Also: How To Factory Reset Hikvision Camera )
Do I Need to Buy a Synology License for Every Camera I Connect?
Yes, Synology Surveillance Station comes with two free camera licenses per NAS. For any cameras beyond the initial two, you will need to purchase additional licenses from Synology to legally and officially integrate them into Surveillance Station and access its full feature set. These licenses are tied to the NAS unit itself.
What Is Onvif and How Does It Affect My Synology Camera Setup?
ONVIF (Open Network Video Interface Forum) is a global standard that allows IP-based security products to communicate with each other. It’s designed to ensure interoperability between different brands. If your camera supports ONVIF, it increases the chances of it working with Synology Surveillance Station, even if it’s not on the official compatibility list. However, the specific ONVIF profile supported by the camera and how well it’s implemented can still lead to connection issues.
Can I Use Cameras That Aren’t on the Synology Compatibility List?
Yes, you can often use cameras not on the official list, but it requires more manual configuration. You’ll typically need to set up the camera using the ‘Manual Setup’ option in Surveillance Station and provide the correct RTSP URL. Be prepared for potential troubleshooting and that some features might not work as expected compared to officially supported cameras.
Verdict
Getting total 4 camera working on Synology isn’t always plug-and-play, especially if your cameras aren’t on that golden compatibility list. The most reliable path, and the one that causes the least amount of hair-pulling, involves purchasing those Synology licenses. It’s a cost, sure, but it buys you peace of mind and a properly integrated system.
If you’re feeling adventurous, or on a tighter budget, diving into the ONVIF settings and fiddling with RTSP URLs can work, but be prepared for a steeper learning curve and potential instability. I’ve found that after my fourth camera setup, the sheer amount of time I saved by just buying the extra licenses far outweighed the initial expense.
Before you buy any new cameras, always check that Synology compatibility list first. It’ll save you a world of hurt. And remember, sometimes the ‘smart’ tech just wants you to pay more for the privilege of using it fully.
