Hi, I need a little help. I have just had a new PTZ camera fitted to my network. It is a Hikvision IR with dark fighter , 25x zoom and with a power of 42watts max. I am only getting black and white images at night. I noticed today that the new Poe switch is an 8 port (all of which are POE+) . I have looked at this on line and it suggests to me that the installer should have maybe installed a POE++ switch or at least a switch that has a POE++ port for the PTZ. There are three other standard 4mp dome cameras on the same switch and they are all ok. Would I be right in thinking that although the PTZ camera shows colour during the day it doesn’t have enough power to utilise all the features such as the lights? I have checked the setting in the camera config and they are all correct.

Typically, the POE+ switches I'm used to, supply a max of 30W per port. Your switch "might" be different.
Log into the switch, and look for diagnostics of some type. Most switches will tell you how many Watts a port is drawing.... or if it's max'd out.
If you have access to a POE++ injector.... it might provide you (or your installer) with some direction on how to proceed.

Ok, so the switch at the time I looked (during the day with max zoom) was taking 30watts. Would I be advised to get another switch that has a Poe++ or would adding an injector help? I spoke with the installer and he told me that he had “mis-understood“ the Darkfighter technology and now realised that I had little chance of getting color images at night unless there was a good source of light. In my case it is looking down a very dark field which at its furthest is about 140metres away from the camera. I now find myself trying to make the best of a bad job. Any ideas are welcome.
I'm not familiar with "all" the functions of that camera.... accordingly I can't comment on what functionality would be missing with only 30W available vs. 42W needed. Maybe someone else can weigh in.

Hi @GaryL
We always recommend that you provide the camera with more PoE than its max. PoE draw.
So with this PTZ requiring a max. 42W, we would recommend that you position a 60W PoE Injector between the switch and the camera to make sure that the camera is receiving enough power.
If you underpower the camera it will likely reboot/stop working/drop off the network when the camera's power requirements exceed the limits of the PoE source it's connected to.

Sir, thanks very much I will get an injector.
