In the application of perimeter protection alarming, the photoelectric beam detector countermeasures are used earlier and more widely. In order to continuously adapt to the market demand, the major manufacturers are continuously improving and upgrading the photoelectric beam detector.Recently, with the rise of intelligent laser intrusion detector, it has attracted much attention in the application of perimeter protection due to its outstanding anti-interference ability, long-distance accurate detection and advantages of lower false alarm.Both of them belong to perimeter protection products. We can compare the performance of intelligent laser intrusion detector and photoelectric beam detector, that users and customers can choose corresponding products according to the actual situation.
Firstly, in terms of detection range, the outdoor detection range of photoelectric beam detector is generally from 50 meters to 350 meters, which is mainly applicable to some residential areas, campuses, factory parks and other applications.Laser detection technology is adopted to intelligent laser intrusion detector, the detection distance is longer, generally in the range of 100 meters to 5 kilometers, and the transmission is stable, more suitable for prison, substation, petroleum petrochemical, railway crossing detection and other occasions.
In the aspect of anti-interference, photoelectric beam detector adopts infrared light detection, which has high requirements on the environment. If the installation is not up to the standard or affected by the interference of branches, wind or other infrared equipment, it is easy to false alarm.Of course, there are some manufacturers in the anti - jamming design, as far as possible to reduce the false alarm of infrared.
Intelligent laser intrusion detector using laser as light source, detection of its own strong electromagnetic interference resistance, and small divergence Angle, more penetrating and can significantly reduce the rate of false alarm, Alean Intelligent laser intrusion detector also embodied in the design of intelligent frequency conversion technology, each beam has a corresponding, transmit and receive frequency can effectively reduce the beam light interference each other.
In terms of detection accuracy, the photoelectric beam detector is usually adjusting the triggered time to reduce the false alarm by small animals or other objects.Intelligent laser intrusion detector used the special digital code technology, cooperate to set the interrupt arbitrary beam alarm, adjust the trigger methods such as response time and the bypass mode at the same time , it can greatly improve the detection precision, and make users more flexible to use it.
In addition, there are some manufacturers have been optimized, improve various properties of intelligent laser intrusion detector, such as the Alean intelligent laser intrusion detector also design special small Windows, four digital tube display signal strength, at the same time, cooperate with laser detector aligner, can realize the fast alignment, reading, analysis of each beam signal strength, easier to debug, greatly reduce the burden of installation . Alean also uses a higher level (CLASS 1) laser head, higher concealment , and will not cause harm to the human eyes,the product realized longer life and more safe!
