What equipment to choose for outdoor security

Unread post by vedard »

Outdoor security equipment installed in Windows and around the house, can prevent thieves in the outdoors, to avoid or reduce the loss of life, property.
There are infrared multiple beams break-in alarm, outdoor infrared detector wide angle 110°or outdoor solar detector 15°. The detection distance can be 10m-100m for infrared multiple beams. And detection distance for infrared detector is 8-10m.
There is 3-beams and 4-beams infrared detector, the more beams the better detection effect?
Four-beam detector means more stability, lower false alarm rate and better adaptability to the environment.It also means higher costs and is generally used more in long distance environments (nominal distances over 100 meters).If the area is small, use less beam to reduce the false alarm rate; if the area is large, use more beam to reduce the false alarm rate.
Sensitivity is the most direct factor affecting the false alarm rate or missing alarm rate. How to adjust the sensitivity so that the false alarm rate and missing alarm rate achieve the desired effect?
In the conventional detection technology, sensitivity is a contradiction between false positives and false negatives. To reduce the sensitivity in order to reduce false positives, the problem of false positives will rise.On the contrary, in order to reduce the omission of sensitivity, it will bring the problem of false positives rise.In practice, it is difficult to accurately grasp this "degree".
The specific setting of sensitivity should be determined according to the actual environment.Generally speaking, if the application environment is harsh, such as frequent birds or floating objects blocking the beam, then the low sensitivity should be set.The active infrared detector should choose the appropriate response time: too short is likely to cause unnecessary interference, such as birds flying over, small animals passing through;Too long will cause underreporting.The minimum shading time is usually determined at a speed of 10 m/s.Sometimes due to the change of seasons, the sensitivity needs to be adjusted separately in winter and summer.
Active infrared working devices are mainly transmitting and receiving lenses. What problems are likely to occur when they are adjusted?
If these two lenses are not adjusted properly, the direct result is that they are off-center, resulting in poor reception.
In general, the adjustment of active infrared detector should be based on the output voltage of the optical end. By fine-tuning the deflection Angle and vertical Angle of the lens, the output voltage of the optical end can be observed. The higher the voltage, the more accurate the detector is and the lower the false alarm rate.Generally, the detector has a minimum output voltage indicator.Now, the installation and debugging are relatively simple, as long as the manufacturer provided by the correct installation method, in general, there will be no problem.
When active infrared detectors are used for perimeter protection, there will be blind corners. How to solve this problem?
Due to the problems of the active infrared detector itself or the geographical environment of the detection area, there will be some small areas or small dead corners that cannot be completely sealed with the targeted detector, which brings some hidden dangers to the security system and reduces the reliability of the whole system.Like the barrel effect, the level of security is determined by the weakest link in the system.Therefore, in order to solve these weak links, it is very necessary to select some small curtain detector used outside to block the dead corner.

What should you know about the beam infrared distance

Unread post by vedard »

Why are there 30 meters, 60 meters, and 100 meters in the infrared beam of the same enclosure? How is the distance defined?
The infrared beam is composed of two parts: a light emitter and a light receiver. Just like a flashlight, the luminous intensity and beam diameter of the light emitter directly affect the projection distance, while the luminous intensity of the light emitter is directly determined by the chip material and luminous area of ​​the emitter tube. The correct selection of chips of different areas can output enough strong light. The ideal focusing lens can ensure the minimum loss of light energy. The combination of the two points can guarantee a reliable acceptance distance. The nominal distance of our products is strictly divided according to the standard requirements, and the nominal distance will have a margin of more than 6 times the nominal distance.
