Outdoor Security System / Security



Motion sensors have been used with alarm systems for many years. In early years, motion sensors were based on ultrasonic technology. Sound waves were emitted from a sensor, and the resulting reflected sounds were analyzed to detect changes. When a change was detected, the motion sensor notified the alarm system’s control panel. These ultrasonic sensors were frequently blamed for false alarm. Today, there are many new technologies to overcome the limitation of ultrasonic technology. The new technology includes motion sensor, infrared light motion detect sensor and more. The diagram above shows an application of Sollae Systems’ remote I/O controller that is applied with such sensors to graft a concept of military outdoor security system.

Microwave sensor is also referred as Doppler microwave sensor which detects movement by using Doppler radar. When there is a trespasser or any motion occurs, the microwave sensor sends a signal to an input port of the remote I/O controller which again sends a signal to the server through network for an alarm.
