Camera(s) keep disconnecting from NVR

[reactiv]

Hi

I have two ColorVu cameras attached to this 4 channel NVR (DS-7604NXI-K1 / 4P) One of the cameras always the same channel keeps disconnecting after a couple of weeks or so
I have tried resetting many times, infact I have replaced the camera on this channel with a brand new unit and the same happens, after a few weeks its offline again! Its not connected to the rear of the NVR its on the network like the other camera.

Any ideas?

Thanks. C

That NVR is rated on 40Mbps bandwidth, which depending on how you have set up the cameras, you could be exceeding it or coming close and then something happens that pushes it over the limit.

You could try dropping the FPS and bitrate of the cameras.

How is this camera coming into the NVR - is it going thru the router? If so that is probably the problem - over time the dropped packets add up on a never taking a break and never buffering video stream and will cause it to start losing connection.

Ah OK thank you The frame rate was set to max, so I'll try it at 20FPS and see what happens the bit rate was/is set at 6144. I'm using a TP-LInk OMADA Router and a Hikvision switch.

Usually Bandwidth never comes into play especially if its dropping offline after weeks. I would def look into statically assigning and Reserving that Address in your router, Could be maybe another device taking that IP. Aswell Try using a different Port/Cable aswell

I have had it confirmed by HIK there is a bug with DS-7604NXI-K1 / 4P firmware (V4.82.100 build 240606) they are working on a fix

After a power cut or manual system reboot, 1 or more cameras are unavailable due to camera channel config corruption, either IP Address, Password, Manual-Auto or all three...
A common observation is that where cameras are connected on the network subnet and NOT directly to the back of the NVR, the NVR when rebooting then assigns the camera channels to the internal NVR subnet x.x.254.1 in Plug and Play mode.

Thanks for everyone's comments.
