Hey there. I have an 8 camera POE Lorex LNR380 system I inherited with the space I am renting for my business. The system is dead and it is most likely the power supply (I tried a different hard drive and it still is just stuck at the Logo screen). I'm thinking of just upgrading to a better NVR and then slowly when I have time go upgrade the cameras to a higher resolution. Can someone recommend a good replacement NVR that is compatible with the installed Lorex cameras?
