Outdoor Waterproof Laser Beam Sensor PIR Infrared Perimeter Barrier

Comparative item

Active infrared detector

Laser detector

Description

Adaption to rough environment

General

Extremely strong

Laser is mono-directional, with small angle of divergence, concentrated beam and strong signal, so t hat even attenuation resulting from rough environment will not influence its normal operation.

Multi-beam detection

Multi-beam simultaneous blocking alarm

Block of any beam of any layer can trigger alarm.

Each beam of laser detector has independent alarm function ; however, multi-beam of infrared detecto r is actually a set of system.

Mutual interference

For multi-frequency product, interference may still occur in straight long distance layout.

Closed-circuit transmission system, free from interference.

Mutual interference can result in alarm omission.

Actual operating distance

The actual operating distance is about 75% of nominal distance.

The actual operating distance is twice that of nominal distance.

Provide wide layout margin for design

Working temperature range

-25℃-55℃

-40℃-70℃

Laser detector can more appropriately resist high or low temperature than infrared detector.

Commissioning mode

Aiming through telescope, long distance commissioning is inconvenient

Adjust by fine adjustment device and laser seeker of laser optical path built in the equipment.

Commissioning of laser detector is convenient, accurate and quick, ensuring no deviation of beam in long-time operation
