Review on 📷 8CH NVR Hiseeu Wireless Security Camera System with Pre-Installed 3TB HDD, 8Pcs 2K WiFi Surveillance Camera, 1296P Waterproof Bullet Camera with One-Way Audio, Motion Alert, Remote Access - Indoor/Outdoor by Roger Weinmunson

Very easy to install and operate. True plug and play technology, a QR code appeared on the monitor to download the phone APP and launched it within five minutes after unpacking the device. Very impressed with the night vision in total darkness. The picture quality is much better than other systems I've had. I have a brick house and I'm having trouble with one of my cameras with a weak signal, so sometimes I can see this image.
