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 Jason Gay

I've had this security system for 2 months now and it works great. If you need notifications when the device is off or motion is detected you can easily set it up, it can be set to email you when an alert occurs or you via the ip-pro app notified to send pop-up notifications. This is really very helpful. Only you have to spend a few hours setting it up the way you want (it took me about 2 hours). I also use the option to connect one camera over another and it works.
