  If your Lorex DVR system isn't receiving power or powering up, check the following: * Make sure the cable from the power adapter is securely connected to the back of the unit and plugged into the outlet. * Confirm the system is powered on by checking the LED indicators on the front. If connected to a power bar or surge protector, try connecting directly to the wall outlet. * Verify the outlet has power by testing it with another device or trying a different outlet.

  If you're not seeing a picture on your monitor or TV after connecting it to the Lorex DVR system, try these steps: * Power off the monitor/TV and the system. Then, power on the monitor/TV first, followed by the system. * Ensure that you've selected the correct input channel on your monitor/TV to which the system is connected. * Check the video cable connection at both the system and the monitor/TV to ensure it is secure. If the issue persists, your camera may not be compatible with the recorder. Visit lorex.com/compatibility and navigate to N842 Series for a list of all compatible cameras.

Why is there no picture on some channels of my Lorex N842A82 DVR?
- A
  Angela KingAug 19, 2025
  If there's no picture on certain channels or a camera picture isn't displaying on your Lorex DVR, consider these potential causes: * The camera cables might be loose or disconnected. Check the video cable and connections, disconnecting and reconnecting at both the system and the camera. Try moving the camera to another channel or use another cable. * The camera may not be compatible with the recorder. Visit lorex.com/compatibility and navigate to N842 Series for a list of all compatible cameras. * If you're using multiple PTZ cameras connected to the recorder’s PoE ports, the recorder’s power output may be exceeded. Lorex PTZ cameras come with a power adapter, which you can use to power the camera instead of the recorder’s PoE ports.
