Dual sensor technology truly takes it to the next level. The 5MP cameras use both a passive infrared sensor and motion sensor to detect humans, animals and vehicles. Where heavy rain, bugs and changes in lighting could potentially produce motion alerts on older systems, this new technology detects both changes in motion and heat simultaneously, reducing the potential of false alerts. The weatherproof cameras are intended for use both indoors and outdoors. The extreme HD cameras provide stunning image clarity with more pixels. Outdoor Use: Yes
