Analog DVR to Synology NAS

I understand that the Synology Quickconnect makes it possible to access cameras without forwarding ports now that I switched to Starlink and can’t forward. However, my current cameras are 12 year old BNC so I’m wondering if these “adapters” to switch them to network are actually reliable. Most of the cameras aren’t accessible to replace the wiring with cat5. Anybody have experience working with old DVR systems to something new? Thanks!

I have never tested those adapters so I don’t know if they work well or not. When we encounter clients with BNC cameras we don’t offer any solution other than replacing them.
