Review on 101AV 4CH Full HD 1080P Security Camera System, 2in1 H.264/H.265 DVR/NVR, HD-TVI/CVI/AHD/IP, 2TB HDD, HDMI/VGA/BNC Video Output, Mobile Apps for Home/Office, Supports Analog & Network Cameras up to 4MP (no PoE) by Marcus Barlow

This was very easy to set up as a replacement for a failing previous system. I just disconnected the lines from the old block, connected them to this one and everything started great. The mobile app recommended in the guide pack must have been changed to not show a p2p client, but I remember seeing a post from the company earlier asking to use the Guardian app instead. Very happy with the easy setup and the iPhone app which works great. With three cameras I'm not sure how long 2TB will record, hopefully at least a week. Another great feature is that it works almost silently. My old machine had a very loud fan. Hopefully this means very efficient heat dissipation. Anyway, I'll keep an eye on this post if anything changes.
