Any recommendation for NVR(record RTSP camera only)

Hi guys. Need some suggestion on selecting NVR platform. Currently I’m using Synology Surveillance Station, which works well but only support one camera with free license, and I plan to add more cameras to my home. I only use this NVR for recording video and replay if necessary, so it doesn’t need to have too many fancy features.

Several aspects to consider:

  1. Cost(open source or not?)
  2. Stability
  3. Easy mobile access
    • I am using Frigate for object detection. It also support s video recording but the playback feature isn’t as nice as Synology Surveillance Station(totally understablable)

I’m open to any suggestion. Thanks!

If you already using Synology, why not just buy licenses for more cameras? (I use it too and have half a dozen camera’s attached)

@callifo I’m using a kinda old Synology NAS(DS219j?) and some articles say that its performance will degrade with more than 4 cameras being attached. In addition, I already have a Dell R720 server in my garage so I’d like to look for something that I can deploy as a VM.

As to the cost, I don’t think Surveillance station is a great deal. Around $50 for each camera? I’d prefer something with one time payment with unlimited cameras. But still thanks for the reply.
