How to troubleshoot a Lorex DVR that is not powering on?
- G
  Gina BrockAug 8, 2025
  If your Lorex DVR system isn't powering on, first ensure all power cables are securely connected, including the adapter at the back of the unit. If connections are good but the system still lacks power, verify the system is switched on and the LED indicators are lit. If connected to a power bar or surge protector, try plugging directly into a wall outlet. Finally, confirm 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/TV after connecting it to the Lorex DVR system, try these steps: First, power off the monitor/TV and the DVR, then power them back on, starting with the monitor/TV. Next, ensure that you've selected the correct input channel on your monitor/TV to which the DVR is connected. Finally, check the video cable connections at both the DVR and the monitor/TV to make sure they are secure.

Why is my mouse not working on my Lorex N881?
- C
  cjohnsAug 16, 2025
  If the mouse is not detected by your Lorex DVR system, ensure the mouse cable is firmly connected to one of the USB ports. If that doesn't work, power off the system by disconnecting the power cable. Then, firmly connect the USB mouse to a USB port and reconnect the power cable to the DC 12V port on the rear panel to restart the system.
