Analysis of infrared alarm works

Prior said infrared alarm, a little talk about the basics . Wavelengths of visible light is generally 0.4 to 0.7 microns, which is the eye can see the light. 0.7 to 400 microns and a section is infrared, invisible infrared light is beyond the range of the human eye can see .Stars Traffic Baton In addition , any object above absolute zero will emit thermal radiation own infrared light , and hot objects such as human body relative to the amount emitted houses, trees, rocks , etc. will be larger . Speaking of which, we know some of the general principles of infrared alarm it.
Since its launch , infrared night vision alarm then its distance, subtle and strong , stable performance , and other prominent advantages, occupy most of the market in night vision monitoring . By emitting infrared detector infrared detection beam , always lock detection range every move. Once intrusion on signal transmission through to alarm host, then an alarm sound from the alarm horn . The sensor has a sensitivity index , also called the illumination value , is the ability to respond to weak light , the higher the sensitivity to light sensing capability is stronger, the stronger the ability to sense infrared .
One benefit is the use of infrared alarm , infrared detector infrared beam emitted by the naked eye can not see the people , the thieves without love , it is likely strayed into infrared radiation zone , once there is an infrared blocking , alarm will immediately alarm. Today, Stars Safety Beacon Warning Light on the principle of a lower infrared alarm today.
