The VX-402REC provides an innovative solution to external area detection. It employs a highly reliable dual detection technique, which prevents false activations caused by small animals and birds. Two discrete detection areas are created and only when an intruder is detected inside both areas is an alarm output triggered. Double Conductive Shielding ensures that the sensor is resistant to interference from foreign light sources such as the sun and car headlights.

In addition, the VX-402REC provides great flexibility in detector-activated voice applications as well as the ability to record messages in any language. With its superior playback settings, it allows the right message to be played in every situation.
