Audited Supplier Digital frequency conversion infrared grating detectorInfrared grating alarm system Anti theft warning system for doors and windows Infrared detector
Infrared grating (also known as electronic grating or infrared fence) (also known as "infrared railings") is a kind of active infrared radiation (what is infrared radiation, please see the details below). It uses multiple beams of infrared light, and the transmitter emits infrared light to the receiver in the way of "low frequency emission, time division detection", Once a person or object blocks any two or more adjacent beams of light emitted by the transmitter for more than 30ms, the receiver will immediately output an alarm signal. When a small animal or object blocks one of the beams of light, the alarm will not output an alarm signal.
Various specifications are available
The detection range is 5 , 10 , 20 , 30 , 40 , 60 , 80 and 100 meters
All in stock , please consult our customer service for details !
Applicable place / case
This product is a universal indoor and outdoor digital frequency conversion infrared photoelectric fence detector , belongs to the planar infrared protection detector , the main control chip and sensor and other key components are imported parts,leading the industry wide voltage range , suitable for villas , residential areas ,factories , schools , institutions and other protection sites 360 Rotation adjustable
Omnidirectional rotation of focus , left and right can be arbitrary rotation 360 , convenient installation , projection of focus in all directions makes installation easier
Four section frequency conversion technology
When installing multiple pairs of gratings , adjacent gratings can be adjusted into infrared beams of different frequencies , and the wire prevents interference between gratings and gratings
Pet-proof , no alarm
When the intruder passes through the infrared grating , blocking the adjacent two or more infrared beams , the alarm output is triggered , while the intelligent detection technology can identify small animals without alarmHigh grade waterproof , dust proof , insect proof , moisture proof ,anti dismantling Stronger environmental applicability , no fear of Wind and rainWiring diagramTechnical paramete
