New Dahua Cameras on old NVR

[anfz]

Hi Everyone,

2 of my Dahua eyeball cameras decided to stop working. After some investigating I realised the 2 cameras needed replacing.
Unfortunately Dahua stopped making the original eyeball cameras so I purchased 2 Dahua 6mp DH-IPC-HDW3641TMP-AS-0280B.

After connecting the new cameras, my NVR was giving me conf.loginerror20-20 error message . When i logged into my NVR via internet explorer it was telling me the new cameras are offline.

My NVR is a VIP VIsion NVR8ENT

I've tried the following options:

• Updated the NVR firmware
• Changed the manufacturer of the cameras to Onvif
• changed the password of the cameras

Your help is greatly appreciated.

Thanks

What is make/model of the NVR?

Do the cameras connect to back of NVR or are they on a POE somewhere else on your network?

If it is old enough it might not be able to accept a 6MP camera.

Are you sure it was the old cameras that stopped working and not the POE ports?

What make and model NVR do you have. As stated it might not be able to handle those cameras.

The Brand of my NVR is VIP VIsion and the Model is NVR8ENT. Here is the link. NVR8ENT: Compact 8 Channel Network Video Recorder with PoE (80Mbps) | RhinoCo Technology

Thanks for your help.

According to the specs, it cannot accept over 5MP:

Resolution 5MP(2560×1920) / 3MP(2048×1536) / 1080P(1920×1080) / 720P(1280×720) / D1 (704×576/704×480)

Log into the camera settings. As previisly mentioned, try adjusting the camera to a lower resolution (1080p). Also, check if the video codec format is set to H.264 (most old NVR only format). Sometimes the camera default are set at H.265
