Amcrest 4K Analog Camera does not work at night! AMC4KBC28-B Power supply too weak?
Amcrest 4K Analog Camera does not work at night! AMC4KBC28-B Power supply too weak?
I purchased 4 brand new 4K Analog Cameras AMC4KBC28-B from Amcrest using their included 0.7A Power Supply and none of them turn on IR at night so the cameras only shows black display at night. I know the Infrared works but I think their power supply is too weak to turn on the IR for the cameras. I know that the camera spec shows 2.0A. I am using Amcrest supplied BNC cables and their own 0.7A power supply. I called Amcrest support but they sent me the exact same power supply which has the same issue. I haven't found any solutions online yet. Has anyone else experienced this?

Hello and Welcome to the Forum
So little confused!? you are using a 0.7a PSU that came with the cameras? However your saying that the camera Requires 2.0amps?
Please note that there is normally 2 numbers that are on PSU's there is the Incoming power and that is what the 0.7amp sounds like it could be.. there should be another set of numbers that would be the Output of the Power supply and should read something like 12v xx amps
So there is something that I would try.. IF that supply is trying to give power to all 4 cameras. Remove the pig tail and install 1 camera to the power supply and see if that makes the camera work..
So another Solution is using a Real Power supply that is designed for CCTV cameras and are used by Pro Installers and they are called PDU (Power Distribution Unit) There are many out there but some of the ones I have used and still own are Monoprice, SPT and Altronix to name a few.. There are lower cost ones and ones that you can adjust the 12v output to help with Voltage drop but to be honest I wouldn't look for the costly ones unless you have long power runs..
This brings me to the next issue.. What is the Distance and what Cables are you using? Sadly some oft he cables from most companies can have flaws and most use some sub standard cables.. So without buying a PDU you could test your Power supply at the camera without trying to power over the Siamese cables as it might be they are run on to small of power wires and this makes the Voltage Drop below what is needed for the camera to work.. Higher the Current demand the larger the wire needs to be.. Having the Power Supply at the camera will confirm that the cable is issue or low current supply
Love to see a Picture of this Power SUpply your working with
