Sometimes these PoE switches don’t output the power listed on the spec sheet. However, that’s not always the case, especially if you’re using an off-brand and cheap PoE switch. A good and reliable PoE switch should be able to handle all the cameras plugged into it. The IP camera gets plugged into the PoE switch using an Ethernet cable and the data and the power is transferred via the same run.Įach IP camera requires a specific amount of power to operate and function efficiently which is called the Maximum Power Consumption (wattage). This is valid for the security cameras that are powered via an external PoE switch. In all scenarios, if you’re not sure about the cable’s conditions then you can test the camera out using another (temporary) cable. Just inspect it to ensure that it works correctly. Most of the time this cable is HDMI (or VGA in older models) and it will show a black screen if it’s faulty or the pins on the connector are broken.

Maybe someone placed a tape over it or block the view or unlawfully repositioned the camera. Once that is ruled out, you can move into other technical approaches.Īdditionally, you may need to check if something is blocking the camera’s lens. In many cases, the camera shows a black screen because it is experiencing power or data loss. The first thing you should do is check the physical connections.
