Review on High-Quality PVO Surveillance NVR Kits, 8 Channel Home Security Camera System with 4PCS 1080P 🎥 WiFi Cameras, Outdoor Built-in Repeater, IP66 Waterproof, Night Vision, Motion Alert, Remote Views, No Hard Disk by Maurice Malek

This security system is largely as advertised. Good image quality and night vision. If you are good with electricity this is not difficult as the cameras need to be within a certain length of an outlet to be plugged in. I'm still trying to understand the recording and playback system. Once you download mobilAPP, it will work very well. The only downside is the support as there is post sale support in China. I can't even get a phone number from Air Defense. So far support is 0. A geek who understands the jargon will be of great help. I'm still trying to figure out the alarm system
