Review on 🎥 Evtevision 10 Channel NVR: High Definition Network Video Recorder for Enhanced CCTV Security (4K/5MP/4MP/3MP/1080P), Remote Viewing & HD Output – No Hard Disk Included by Jon Lewis

Firstly, they didn't even update the instructions, it's for older models. They are nothing more than printouts from someone's computer. It's even difficult to read. The only thing inside is a small control board with hard drive cables. But the wires are short and there are only 4 holes to screw in the hard drive, making it unnecessarily difficult. Embedded software looks like we saw hardware in the last millennium. The iOS app isn't much better (3 stars or less). You can access what deserves a star on its own through a computer browser. I was able to add an ONVIF camera which is working so far. But I couldn't add any of the other 15 cameras we have, including a DVR, although it's possible. It's cheap and you won't get much. Too expensive for what you get.
