Performance Comparison of Laser Beam and Pulse Electronic Fence
2021.01.21
Both laser beam and electronic fence belong to the perimeter prevention system, and are currently two more widely used solutions in perimeter alarms. Laser beam and electronic fence have their own different advantages. This article will take you to understand and compare the two perimeters Program.
 
How Electronic Fences Work
The working principle of the electronic fence is: the high-voltage output terminal of the fence host sends a high-voltage or low-voltage pulse voltage to the front fence. The pulse voltage forms a loop on the front fence and is transmitted back to the receiving port of the host. The pulse electronic fence host detects that the loop on the front fence is normal and No, and send an alarm signal according to the status of the fence. If an intruder climbs or cuts off the electronic fence, it will cause an open or short circuit in the pulse circuit, which will cause the host to alarm. Pulse electronic fences are widely used in communities, military, airports, prisons and other occasions.
Electronic fences have become the "new favorite" in the field of perimeter prevention with many advantages such as low false alarm rate, strong deterrence, high safety factor, and beautiful appearance. Whether it is a campus, a community, a prison, or a detention center, electronic fences will give full play to their advantages to ensure the safe operation of all units.


The Working Principle of Laser Beam
The laser through-beam intrusion detector is an anti-intrusion alarm developed based on laser technology. It is divided into a transmitter and a receiver. The transmitter is the transmitting end, which can emit multiple modulated laser beams to the receiver. When there is no obstruction between the transmitter and receiver, the detector will not alarm. When an object is obstructed, the receiver detects a change in the signal and an alarm occurs.
Laser beam intrusion detectors are mainly used in long-distance perimeter environments such as airports, prisons, campuses, the military, substations, petroleum and petrochemicals, and railway platform crossing detection.


Performance comparison of laser beam and pulse electronic fence:

Device Type Laser Beam Pulse Electronic Fence
Detection Method
 
Use non-visible laser light source to detect,
Lower false alarm rate
According to the pulse voltage
Signal an alarm signal
The installation of wiring Need to adjust the light (it is faster with laser guide) and adjust it according to the signal light Traditional wiring method,many accessories make installation more complicated
Anti-interference Performance
 
Laser is a kind of light with very strong energy, it has strong penetrating power and with a smaller divergence, during continuous work, its transmission attenuation is also smaller and false alarms are lower Overcome the traditional infrared and other technical defects, the alarm is basically not affected by climate, terrain, trees, small animals, etc., and the anti-interference performance is better
Power Supply Adopt wide voltage power supply, support AC/DC9~30V input, support a set of relay output, NC/NO optional DC 12V/3A
