24.1.1 Going over PoE budget will result in video loss
Our recorders use Power over Ethernet (PoE) technology to deliver power to IP cameras and the
same PoE is used to transmit video back to the recorder.
Known as Maximum Power Consumption (wattage), each IP camera requires a specific
amount of power to operate and function efficiently. You will find the Max Power Consumption
on the camera's specification sheet in the Download section of the camera's product page.
Our Network Video Recorders (NVR) have a total power output or PoE budget of between 80
and 220 watts. When adding additional cameras to your recorder, please ensure that you do not
exceed the PoE budget. If you go over your PoE budget, the system will shut down or drop a
camera as it does not have enough power to supply to the camera, resulting in video loss.
When adding cameras to your recorder, please make sure you are within your wattage allowance.
Please refer to the image below to get an idea on how to calculate your PoE budget.
24.1.2 When to use a PoE Switch?
If you find that your recorder does not have enough power to support the camera(s) you have
added, you have the option of using a PoE Switch to increase the power to the recorder and ex-
tend the range of your cameras at the same time. To purchase a PoE Switch, check out our 8 or
16-channel PoE Switches here.
24.1.3 Not enough power or total loss of it
Loss of power is the most common reason why security cameras go black. It happens when
power adapter is disconnected and cable that connect the camera to the recorder and monitor be-
comes loose and faulty.
