Perimeter protection is the first defense line for the intrusion detection, it's most important and crucial for the whole security system. Now with different technology, there are two different perimeter protection: Active infrared beam and electric fence. Electric fence with disadvantages of high cost and appearance, effectiveness, so the electric fence doesn't widely used in perimeter protection. On the contrary, active infrared beam sensor occupied most market for the perimeter protection projects. Even though compare with electric fence, installation for the infrared beam sensor is pretty easy, but the wiring, construction works are very hassle.
Wireless solar infrared beam working theory
For better meet the demands from security market, now some manufacturer launched some new perimeter sensors - wireless solar active infrared beam sensor. Utilising wireless and solar technology solved the troubles when install and maintain the perimeter sensor. The basic design layout main features as below:
Wireless solar infrared beam sensor utilized solar power, transmit signal via wireless technology, without cable wiring, it's complete wireless beam sensor, effectively solved the problems for beam's installation, it's working theory is similar to wired infrared beam sensor, but degrade the power consumption.
Disadvantages and solution
Above two disadvantages are related to the hardware technology, it may cannot be solved completely. Reducing the problem from the ligh condition, wireless solar infrared beam sensor using special material to insure the infrared beam can work at low illlumination condition, the amorphous silicon working at 1600LX (Normal raining weather: 2000LX) light condition, the solar panel can output the current, event the ligh is insufficient, the beam still can work.
