Review on 🚪 Lorex 1080p Wi-Fi Video Doorbell Security Camera with Motion Detection, IR Night Vision, Ultra Wide Angle Lens & 2-Way Talk – Includes 16GB SD Card [Requires Wiring from Existing Doorbell] by Duane Hayes

Only need the main camera to remotely monitor the front door. This works very well. There are settings to choose sensitivity, and for our situation, it's safe. It activated once during a monsoon storm, but this is an exception. The electricity went out in the house while we were driving and we didn't know it. When checking the "Live" camera, other settings were not effective. However, once power was restored, everything was back online and running as usual. Installation time, including installing a camera in place of our old doorbell, was about 1/2 hour. We have never used or installed any of these. Never needed tech support.
