When night version precise dot alignment is in serious need, not able to rely on a simple IR laser pointer or any other manual dot projecting tool, it would make even better job to apply a long wavelength of 980nm made device, such as an infrared laser diode module. It gets a bit longer wavelength than other visible optical spectrum. Basically it applies an import IR laser diode and a qualified optic lens inside a durable metal housing tube, equipped with basic thermal emitting system. On condition that direct diode emission made infrared dot laser alignment makes proper installation or integration into night version device, not limited by any work distance and lighting occasions, it is providing professionals ideal IR laser light source for all security devices conveniently.
The 980nm infrared laser diode module is an ideal light source for security night vision, covert monitoring, and perimeter alarms. It gets featured advantages of no red flash, strong concealment, good penetration, and stable durability. 980nm wavelength has a weaker red blast than 850nm, making the light spot almost invisible. It doesn’t expose the camera or supplementary lighting position at night, preventing theft and vandalism. Employed by an import 980nm infrared laser diode within 100mW to 500mW and 600mW to 1000mW output power, infrared dot laser alignment enables strong penetration and anti interference IR light source generation, not affected by fog, haze, dust, and light rain or snow, providing more stable imaging in complex night time environments.
Either dot measuring work is processing at close or long distance in security field, the concentrated beam energy from a 980nm infrared laser diode module provides good long distance directivity, saving more power than floodlighting, suitable for long term security monitoring. Being made with APC, ACC driving circuit board and basic thermal emitting system inside its durable anodized aluminum alloy housing tube with different dimension, this infrared dot laser alignment supports 24 hours continuous operation, with a lifespan typically up to 10,000 hours, meeting the long term maintenance free requirement of security equipment. It can also be designed with TTL modulation type and supports high frequency switching, enabling strobe lighting and synchronous image capture while reducing power consumption and heat generation.
Core Applications in the Security Field
Infrared Night Vision Illumination and Auxiliary Lighting. 980nm infrared laser diode module is used with night vision cameras, PTZ cameras, and bullet cameras, invisible to the human eye, with no red glow, providing concealed illumination at night, improving image clarity in low-light/completely dark environments.
Concealed Monitoring and Security Detection. IR laser dot is used for perimeter protection, silent monitoring in corridors/stairwells/garages, warehouses, checkpoints, etc., without revealing the device’s location.
License Plate Recognition/Face Recognition Illumination. Precise dot-matrix lighting reduces reflections and overexposure, improving the accuracy of license plate and face capture at night.
Laser Beam and Intrusion Alarm. 980nm infrared alignment laser is used with a receiver to form an infrared warning line, an alarm is triggered upon obstruction, used for perimeter protection of walls, pipelines, and important areas.
Night Vision Aiming and Auxiliary Positioning. Infrared reference dot indication and positioning for security and inspection equipment, usable covertly both day and night.
