What to do if my Lorex D841 DVR is not receiving power?
- N
  nelsontoddJul 27, 2025
  If your Lorex DVR is not powering up, ensure all power adapter cables are correctly and securely connected, especially at the back of the unit. Also, confirm the system is powered on by checking the LED indicators. If connected through a power bar, try connecting directly to the wall outlet. Check the outlet's functionality by testing it with another device or using a different outlet.

Why is my Lorex DVR hard drive not detected?
- P
  Pamela FrostAug 13, 2025
  If the hard drive in your Lorex DVR is not detected, the hard drive cables may be loose or not properly connected. Remove the housing and check that the hard drive cables are firmly connected. Alternatively, there may be no hard drive installed in the system. In that case, open the housing and install a compatible hard drive.
