I have a Zmodo 8 camera DVR that I've had for almost 6 years now. It's performed well. I've replaced the Hard Drive only once.
Recently I've had a problem with the Network Type changing from Static to PPPOE. Not sure what's causing it to loose it's setting after certain periods of time. It usually keeps it for a few days, but after some time, I find I can't reach the DVR remotely. I access locally and find the Network Type has changed to PPPOE..
