Infrared anti-theft anti-theft, also known as active infrared intrusion detectors, beam intercept sensors, perimeter alarm, also referred to as infrared radiation.
Infrared anti-theft device is composed of two parts: transmitting or receiving device.
Infrared anti-theft anti-theft work principle :
The infrared transmitter drives the infrared light emitting diodes to emit a noisy modulated infrared beam. At a distance from the infrared transmitter, an infrared receiver is placed in alignment with it. It receives the infrared radiation energy discovered by the transmitter through a phototransistor and converts it into an electrical signal through photoelectric conversion. This electrical signal is sent to the alarm controller circuit after appropriate processing.
The optical systems that are respectively placed at the receiving end and the emitting end are generally optical lenses that act to focus the infrared beam into relatively fine parallel beams, so that the infrared light energy can be transmitted in a concentrated manner. Infrared light is in the spectral range that is invisible to the human eye. Some people pass this invisible blockade line and must obstruct the infrared beam completely or partially. The intensity of the electrical signal output by the receiving end will change accordingly, thus starting the alarm controller to send an alarm signal.
Infrared security is characterized by the detection of very high reliability.
Applications: Widely used in perimeter prevention, urban security, villa walls, community perimeters, factory warehouses, companies, schools, homes, warehouses, resources, oil and many other fields.
Installation method: The transmitter and receiver are installed in different locations: opposite installation type and reflective installation type. The reflective installation type receiver is not directly receiving the infrared beam emitted by the transmitter, but received by the reflector. Or an appropriate reflector (such as a lime wall, a paint layer with a smooth surface on the door panel) reflects back the infrared beam. An alarm signal is issued when the position and direction of the reflective surface are changed or one of the infrared-emitting light beam and the reflected light beam is blocked so that the receiver cannot receive the infrared-reflected light beam.
