Infrared is an invisible light, and it will diffuse. After being projected, a cone beam will be formed in the initial path stage. With the increase of the emission distance, its ideal intensity and the emission distance decay in inverse square. The following editors introduce the advantages and disadvantages of infrared radiation.
Advantages of infrared radiation
Concealed defense method: make intruders unknowingly call the police.
The perimeter is fully fortified: no blind spots and dead ends.
Complete defense capabilities: Intruders cannot pass the stealth infrared defense beam net's defense range with rapid jumps, dormant or other actions.

Strict anti-destructive ability: When the infrared receiving end power line or signal line is cut, the alarm signal output circuit will automatically output a wireless alarm signal.
Can work around the clock. Infrared through-beam detector anti-interference ability of bad weather environment.
Disadvantages of infrared radiation
Birds, animals, temperature, light, air movement, fog, rain and snow, and other environmental factors, as well as factors such as installation methods, angles, and positions, can easily cause false alarms.
The above is the introduction of the advantages and disadvantages of infrared radio, you can find out.
