C3 Laser Beam Intrusion Detection System
Reliable and cost-effective protection for short-distance perimeter security.
- Fast Detection
- Stable Operation
- Dual-light Source Design Allows Quick Alignment and Less False Alarm
Laser Through-Beam Category Advantages

Strong Beam Penetration

Even in rain or fog, the beam can still reach the receiver normally, helping avoid false alarms.

The laser’s extreme monochromaticity makes it less likely to create false alarms due to interference.
Our Laser Beam Intrusion Detection System Solution
Our C3 All-Network Intelligent Laser Beam Solution creates an invisible laser detection line between the transmitter and receiver. When the configured beam is blocked, the system triggers an alarm for entrances, walls, corridors, and perimeter zones.
- Laser Beam Detection: Coded laser beams detect blocking events and trigger alarms quickly.
- Fast Alignment: Red light supports visual alignment; laser handles concealed protection during operation.
- Smart Alarm Logic: Adjustable beam quantity and trigger time help filter short-term disturbance.
- Networked Management: Supports RS485/TCP/IP, remote parameter setting, and alarm/video linkage.
- Outdoor Deployment: IP66 housing, -40°C to 80°C operation, ±20° adjustment, and flexible power options, support wall, pole, slope, solar, and battery-powered sites.
Core Strengths

Lower False Alarms
Laser penetration and narrow-band filtering reduce interference from rain, fog, dust, and strong light.

Easier Installation
Red-light alignment, one-click tuning, and OLED status display simplify commissioning.

Smarter Detection
Per-beam control and adjustable alarm timing help distinguish intrusion from temporary disturbance.

Lower O&M Cost
Remote settings, local upgrades, rugged housing, and flexible power reduce maintenance workload.
How It Works
The working principle is based on the emission and reception of the laser beam. During operation, the transmitter is adjusted to emit the laser beam to ensure that the beam is normally received by the receiver. When an object blocks the beam, the laser beam system will generate an alarm.

Frequently Asked Questions
How does the C3 Series Laser Beam achieve covert perimeter security?
The system uses an 808nm invisible laser as the detection light source. While achieving perimeter security, it offers extremely strong concealment, making it difficult for intruders to detect the detection path.
How does the system solve the problem of signal crosstalk when multiple laser beams coexist?
The system applies intelligent frequency conversion technology, assigning a unique transmission and reception frequency to each pair of laser beams. This physically avoids signal interference between adjacent devices, significantly reducing the false alarm rate.
How is the system's reliability ensured in harsh weather conditions such as fog and rain?
Lasers possess extremely high collimation and energy density, giving them strong penetrating power. The C3 Series optimizes its algorithms to effectively suppress environmental interference from wind, frost, rain, snow, and fog, ensuring system stability.
What is the practical technical significance of the "Dual Light Source Design" for engineering installation?
The main unit integrates a red auxiliary light and the invisible laser. In alignment mode, the red light serves as a visible reference, assisting technicians in quickly completing optical axis calibration. In working mode, it switches to the covert laser.
How does the system filter out instantaneous obstruction interference caused by birds flying over or falling leaves?
The system supports customizable alarm trigger response time (adjustable from 10ms to 500ms). By setting a reasonable response threshold, the system can identify and filter out instantaneous foreign object obstructions, triggering alarms only for actual unauthorized intrusion.
In what aspects is the system's remote management capability reflected?
The system supports RS485 or network communication. Management personnel can remotely adjust alarm thresholds, arm/disarm, and switch modes via software without needing to go to the perimeter site, greatly improving operational efficiency.
Does the system have a security protection mechanism if the equipment is illegally disassembled or replaced?
The system is strictly designed according to the highest national security level. It features an equipment anti-replacement alarm and a removal-from-installation-surface alarm function, ensuring the integrity and security of the front-end hardware.
What standard does the C3 Series achieve in terms of physical protection level?
The product uses a high-strength aluminum alloy housing and achieves an IP66 protection rating. It can withstand water and dust ingress in extreme environments and operates reliably in a wide temperature range from -40°C to +80°C.
