Brasília Distance Trigger



Active infrared intrusion detectors should choose the appropriate trigger response time: response time is too short to cause unnecessary interference, such as small birds flying over, falling leaves and other trigger false alarm; too long is easy to form a leak alarm. The national standard GB10408.4-2000 active infrared intrusion detector stipulated that ≥40ms is the alarm triggering time, which is the application condition of the traditional active infrared intrusion detector usually installed in the traditional modeling wall head. For installation in the ground, it is necessary to run the maximum speed of 10m/s to determine the shortest light-shielding time. If the width of the person is 20cm, the shortest interruption time is 20ms.

Application advantages
1, the use of infrared beam, the human vision is not visible, with a covert defense: the intruder unknowingly touch the police.
2. The traditional active infrared intrusion detectors have a low protection surface, and are prone to blind spots or dead spots. There are no blind spots and dead spots in multi-beam long distance infrared curtain wall products.
3, complete defense capabilities: intruders can not jump quickly (products that can achieve ≥ 20ms trigger the alarm to have this feature), crouching or other actions through the infrared infrared defense beam network defense range.
4, good anti-jamming characteristics: the use of blocking all infrared pulse encoding beam alarm trigger conditions, when the insects, deciduous or small animals through the infrared defense beam network, because it can not completely block all the infrared pulse encoding beam so it is not Will generate false alarms.
5, strict anti-destroy capability: When the infrared receiver power line or signal line is cut off, the alarm signal output circuit will automatically output wireless alarm signal.
6, can work all day. Infrared radiation detector implementation of national standards GB10408.4 - 2000 active infrared intrusion detector "4.1.7 Detection distance b) Outdoor use: The maximum beam distance of the active infrared intrusion detector should be the detection distance specified by the manufacturer "More than 6 times" requirement to resist rain, fog, haze, strong water vapor, strong sunlight attenuation to the beam, resistance to strong winds (especially lateral high winds) blowing and causing beam shifts and other adverse weather and weather conditions interference.
