Wireless alarm system from Hikvision with motion detector, door/window sensor, alarm for sound warning, and remote control. 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.
