Since installing my system in February, I've run firmware version 4.1.64. During that time I added four 2355's and one 2385. All five connected within 60 seconds when added to a POE port.
A few weeks ago I upgraded my NVR firmware to 4.21.005. Shortly thereafter I attempted to add a sixth camera, a 2455 cube camera. Per this thread, the NVR would not recognize the camera when connecting to the POE port. Details in this thread:
NVR will not recognize 2CD2455FWD-IW cube camera
Today I added two more cams, 2355's. I ran into the same problem in that the NVR would not recognize the cameras no matter what. Since they are turret cams and not a cube like the 2455 (with a separate power cord), I was kind of stuck. With no businesses open due to a national holiday for me to buy a switch with a power injector, I decided to roll back the NVR firmware to 4.1.64. Both cams were immediately recognized just like before.
With time on my hands, I decided to experiment. I factory reset the two new cams and upgraded the NVR firmware to 4.21.005. Then I tried adding the two new cams to the POE ports and again, the NVR would not recognize the cams. I then upgraded to 4.21.008 and had the same problem. When I rolled back to 4.1.64 the cams were again immediately recognized. Resets were done on the two cams in between each phase of this experiment. This issue was repeatable every time I tried it.
This tells me there is a problem with the NVR firmware above 4.1.64. Has anyone else had problems adding cams to POE ports with firmware above 4.1.64?
