Review on 3MP Dual WiFi Audio Camera: xmartO AC Powered Home Security Camera System with 4X 3MP Wireless Outdoor Cameras - Ideal for Home and Business Surveillance (Dual WiFi in NVR, 1TB Hard Disk Version) by Christopher Cheek

Setup and usage instructions are vague. The picture is good during the day, but it is normal at night. The infrared lights emit a red glow at night that attracts flying insects, causing motion activation even at the lowest sensitivity setting. Had to turn off mobile push notification because of bugs. Flying insects also activate the notification during the day. If the monitor (TV) has been turned off for a while (just a few hours) and turned on again, you need to change the window view to view images from the camera. We haven't configured (changed) the recording time for the cameras yet, but we will edit this review.
