Boogieman, Thanks for the response. All four cameras are set to VBR but respond as I mentioned in my original post. When I change the low bit rate camera from VBR to CBR the bit rate does come up to ~75% of the other three cameras. Changing the other three cameras to CBR from VBR makes no difference in their bit rates. As for the night time differences I have put the suspect cameras in a dark room and compared them to a "normal" camera. I still get the brighter central image with the suspect cameras. I'm beginning to think they are just more sensitive but I don't understand the bit rate differences.

I recently purchased a Lorex LNR182 POE system with three LNB3143B cameras. A few weeks later I purchased another LNB3143 camera. It arrived as a LNB3143RB. It shows a brighter central image at night with less noise than the other three cameras, daytime appears OK. Looking at the bit rates it averages 60-80 kb/s and 30-40 MB/h which is much lower than my other three cameras. They average 4000kb/s and 2000 MB/h. Tech support replaced the camera with a LNB3143RC and it has the same low bit rates as the one that was replaced. Is there something different with the -RB and -RC models? Tech support wants to send me another replacement but I am not sure that is the problem. Any ideas would be appreciated.
