Micro Wave Detectors

These detectors use high frequency radio waves (micro waves) to detect movement. The micro wave energy will penetrate and pass through all building construction materials like wood, sheet rock, cinder block, plastic, glass and brick and is reflected by metal. Because microwave energy will penetrate, application and installation requires careful consideration. Microwave has much greater range than ultrasonic. Basically, such a detector emits high frequency waves that form a pattern after getting reflected or absorbed by different objects in the vicinity. If there is any movement in the vicinity then the pattern changes and the same is then used for Receiver unit to detect the intrusion. The Receiver, in turn gives input to the control panel to trigger the alarm.
