Wireless motion sensors from Ajax for alarms are protected from hacking by block encryption with a dynamic key. The wired motion detectors for communication with the control panel use Fibra’s digital generation wired technology, which combines the reliability of wires with the flexibility of radio communication. Depending on the sensor type, they can be installed indoors and outdoors. Both wired and wireless devices are available in the Ajax motion sensor product line. When the sensor detects the movement, it analyzes the thermal radiation of the body and raises an alarm when it is certain that it is a person. Motion sensors of the Ajax security systemĪjax wireless and wired motion detectors detect the presence of strangers in a guarded room or territory from the very first steps. They help to effectively identify intruders and prevent theft and damage to property. Motion sensors are used in security systems that are designed to protect residential buildings and apartments, offices, studios, banks, movable property, etc. Such devices for detecting objects most often use a microwave detector and an infrared sensor. Combined motion sensors for alarms combine several detection technologies. Such devices stand out for their high accuracy, responding even to minor movements at low speed. Microwave motion sensor capable of detecting movement behind thin partitions. When a conductive object in motion appears in the detection zone, an alarm will be triggered. Microwave motion sensors signal changes in the reflection of radiated electromagnetic waves.An ultrasonic motion sensor is used in rooms with complex architectural features, since it is with the help of such a device that it will be possible to fully control the “blind” zones. The motion detection signal is fixed after changes in the emitted and received waves. The sensor is equipped with a generator of sound waves, which are reflected from surrounding objects and enter the receiver. Ultrasonic motion sensors detect movement after scanning an object guarded by ultrasonic waves.Such a sensor does not emit anything, it only works as a signal receiver, which indicates a high level of safety in its use. Objects emit heat, a sensitive sensor behind the segmented mirrors of the device registers this, and the sensor is activated.Ī security system that operates on the basis of IR radiation is used indoors and outdoors, since such a motion sensor takes into account only the own temperature of objects. Infrared motion sensors of the burglar alarm detect changes in thermal radiation from objects in the territory under protection.Motion sensors for the security system are divided into 4 types according to the type of operation: Some motion sensors for the protection of the premises are immune from triggering on pets, for example - the device does not work on the movement of an object whose weight is less than 25 kilograms. Wired ones require cabling, while wireless ones use a radio signal to transmit information. How to connect to the alarm control panel: wired and wireless. Security motion sensors are distinguished by the method of attachment: wall-mounted and overhead. The detector is designed to monitor a certain area in a building and send an alarm when a person is detected in motion. One of the important elements of a security alarm is a motion sensor. Security devices help not only to independently control the situation at the facility, but also to connect to the central monitoring console of the security company. This is one of the easiest ways to protect a room. In order to protect the premises from intrusions, thefts and damage to property inside, a burglar alarm is used.
