Alarm system with motion detector, door/window sensor, and alarm for sound warning. Motion detectors have the ability to detect small changes in the environment caused, for example, by human body movement. Additionally, door/window sensors consist of two parts, one of which is placed on the moving part of the door or window, and the other on the fixed frame. In this way, when the two contacts are separated, the alarm is automatically activated.

The set includes: 4 Motion Detectors, 2 Sirens, Hub and Keyboard
