Not only does this camera come with an advanced 1080p sensor with 100-degree viewing angles and night vision, it also utilizes the Dual Sensor technology to reduce false alarms. By incorporating an infrared sensor into the 1080p camera, both motion detection and heat detection are used to minimize false alerts and keep you apprised of real threats in real time. The passive infrared sensor detects heat produced by humans, animals and vehicles. Whereas heavy rain, bugs and changes in lighting could potentially produce motion alerts on older cameras, this technology requires both changes in motion and heat be detected simultaneously. Not only does this technology significantly reduce the number of false alerts you receive, it also conserves hard drive space. This guarantees that you are made aware of those threats that pose great risk to you and your loved ones without having to sift through unnecessary recordings. This truly is innovation right at your fingertips!
