DualCurtain Outdoor controls your property perimeter without creating obstacles for people who are already inside. Two independent optical systems with narrow viewing sectors and flexible settings allow you to accurately adjust 30 meters of the detection zone, excluding possible sources of false alarms. The ELSA (Extended Live Signal Analysis) unique software reacts to intruders, screening out triggers like natural interferences and pets. DualCurtain Outdoor combines patented lens systems, a new digital algorithm to counter false alarms trained on millions of triggerings, a motion detection in a near area option, and highly flexible settings. All of this runs on battery power for years.
