At present, our common perimeter prevention and alarm systems mainly include electronic fence systems, leaky cables, vibrating optical fibers, laser beams and infrared beams, etc. Each of these solutions has its own advantages.
As a hot laser beaming solution in perimeter applications, it has the advantages of strong anti-interference, low false alarm rate, and long detection distance.
In actual applications, how does the laser beam start the alarm?
It is different from the infrared beam, when someone invades and interrupts all the infrared beams, the alarm will be triggered. It is also different from the pulse electronic fence, when someone touches or cuts the front alloy wire, it will trigger the alarm. The laser beam mainly relies on blocking the beam to alarm. When someone invades the fortified area and interrupts the laser beam, an alarm will be generated and the alarm information will be returned to the control host and management platform. The laser beam has strong emission capability and high energy concentration, and the divergence angle is small, so it receives less external interference, can greatly reduce the false alarm rate, and the system runs more stable.
In terms of the performance of laser beaming, Alean has been optimizing. In terms of its alarm mode, Alean laser beam supports setting to block any adjacent one beam, two beams or multiple beams. On demand, adjust the beam alarm mode of the laser beam, you can set to trigger one beam alarm, two beam alarm or multiple beam alarms, which is more user-friendly.
In addition to setting an alarm to block any beam, Alean Laser also supports a bypass mode, which can shield any beam at the receiving end, and the shielded beam does not work. It is very flexible in practical applications and can be bypassed according to needs. Corresponding beams can realize accurate and effective detection.
In order to reduce false alarms to a greater extent and achieve precise detection, Alean Laser also supports adjusting the alarm trigger response time, that is, when there is an object blocking the beam, the blocking time can be used to determine whether or not an alarm is detected. The response time of the radio alarm trigger can be accurate to milliseconds, and multiple response times such as 50ms/100ms/300ms/700ms can be set to meet the needs of users in different environments and different uses.
By adjusting the laser beam's alarm mode, setting the shielding beam, adjusting the alarm trigger response time, etc., it can greatly reduce the false alarm of the laser beam in operation, without being interfered by small animals, branches and other objects, and realizing accurate human detection.
