Overview

Infrared grating, also known as electronic grating or infrared fence, is a type of active infrared detector. Using frequency conversion mutual emission technology, once a person or object blocks the infrared beam between the grating host and the grating slave, the factory defaults to blocking adjacent two or more beams, and immediately outputs an alarm signal.

Product Features

·The closed external wiring structure design innovatively draws inspiration from the inverted design of the bottle cap while retaining the external connection

At the same time, the waterproof performance of the grating has been improved to a new height;

·Adopting digital frequency conversion technology and 32-bit high-speed MCU control, the overall stability is better and the reliability is higher;

·Adopting high-end aluminum alloy shell, designed with anti disassembly, anti shear, and anti movement functions;

·Supports asynchronous and synchronous working modes (factory default is asynchronous working mode);

·Adopting frequency conversion mutual emission technology, two frequency segments can be selected (factory default is A-frequency working mode), solving the mutual interference between adjacent infrared gratings and avoiding direct sunlight, flashlights, and car lights.

·Support dual beam recognition function, which can effectively prevent false alarms caused by small animals, flying geese, etc;

High sensitivity, adjustable three levels of prevention and alert distance;

Strong anti-interference ability: can be used in harsh outdoor environments such as wind, frost, rain, snow, fog, tide, and slanting sunlight;. Independent anti disassembly switch, designed to be more reasonable and reliable, ensuring that the grating is not damaged by disassembly;

·Support buzzer calibration prompt;
