Camera not switching to night vision

[mutley1896]

Hello, I have a DS-7616NXI-K2/16P NVR with a mixture of dome cameras. I have one POE channel who's camera doesn't switch to night vision but works ok throughout the day. The camera is a DS-2CD2142FWD-I, one of 7 on the NVR. The current NVR is an upgrade from a DS-7608NI-K2-8P that is why some of the cameras are considered legacy. The rest of the dome cameras work ok. I have the old NVR in my garage as a test system, so I have removed the offending camera and popped it on my test system and it works ok at night. Return it to the business location, same channel and it fails. As a test I have tried a different camera on that channel and it exhibits the same night symptoms. AI has suggested that the channel profile for the camera has become corrupt. Has any of you guys come across this before. I welcome any input. Apologies for the long post.
Thanks.

If you mean it's staying in colour and not auto switching to mono with IR....You say it works normally on the test system and you get the same issue using another channel. It sounds to me as though there's a light source in that location that's sufficient to keep the camera from switching to night mode. You could just decrease the exposure time on the camera from it's default (1/25 sec) to something like 1/100 sec which would encourage the camera to switch.

Its only this one channel with two different cameras. Attached is how it looks on the NVR and web view. The corridor when locked up has very little light as shown. The other image is when the lights come on.
Thanks for your reply.

Try the affected camera plugged in at the NVR. If it works normally there then it's likely something in the camera view. Or even just spin it around to a different view to prove the theory.

Thanks for your input. I will try plugging in at the NVR and see what transpires. Unable to do this till Sunday so I will let you know how I get on.
