AJAX CombiProtect Jeweller (white colour version) combines two types of security devices – motion detector and glass break detector. Thermal PIR sensor detects intrusion into a protected room by detecting moving objects with a temperature close to the temperature of the human body. However, the detector can ignore domestic animals if the suitable sensitivity has been chosen in the settings. The electret microphone is responsible for glass break detection. The intelligent event registration system requires a sequence of sounds of a specific nature – first dull blow, then ringing sound of falling chips, which prevents accidental actuation.
