Vertical-cavity surface-emitting lasers (VCSELs), leveraging their exceptional properties in the near-infrared wavelength range (e.g., 850nm, 905nm, and 940nm), are reshaping the security industry. Their powerful penetration, anti-interference capabilities, and low power consumption make them ideal light sources for applications such as facial recognition access control, intelligent surveillance, intrusion detection, perimeter defense, and drone detection. As an innovative company specializing in VCSEL packaging, Yuanjing Optoelectronic Technology provides critical support for the development of intelligent security through its high-quality solutions.

Core applications of VCSEL in the security market

1. Facial Recognition Access Control System

VCSELs emit 940nm infrared light, providing precise illumination for facial recognition access control systems. This wavelength captures facial features like contours and texture, enabling rapid authentication. This invisible wavelength reduces visual distraction and enhances the user experience. Thanks to high-performance VCSEL technology, access control systems offer significant improvements in security and convenience, and are widely used in locations such as office buildings, residential communities, and airports.

2. Intelligent Monitoring

VCSEL LiDAR technology (850nm or 940nm wavelength) has brought breakthroughs to intelligent surveillance, accurately measuring target distance and speed, supporting target tracking and behavioral analysis. In traffic monitoring, VCSEL LiDAR can monitor vehicle trajectory and speed in real time, helping to prevent traffic accidents and improving monitoring efficiency and intelligence.

3. Intrusion Detection

VCSELs demonstrate the advantages of high sensitivity and low false alarm rates in intrusion detection, enabling rapid detection of unauthorized intrusions and triggering alarms. Compared to traditional technologies, VCSELs are more stable in complex environments and are suitable for protecting high-security scenarios such as warehouses, museums, and parking lots.

4. Perimeter protection

VCSEL LiDAR sensors excel in perimeter defense, monitoring area dynamics in real time, detecting unusual approaches, and triggering alarms. Their long-range detection and high sensitivity significantly reduce false alarm rates and labor costs, providing reliable protection for factories, military bases, and other applications.

5. Drone Detection and Countermeasures

With the increasing popularity of drones, drone detection has become a new security requirement. VCSELs use infrared light of specific wavelengths to precisely locate drones. Combined with jamming technology, they can force drones to land, ensuring airspace security in scenarios such as airports and major events.

Unique advantages of VCSEL technology

1. High-precision ranging and positioning

Compared with ultrasonic and microwave technologies, VCSEL lidar technology has higher ranging accuracy, longer detection range, and sub-millimeter positioning accuracy , providing reliable data for security systems.

2. Low power consumption and fast response

The low power consumption and fast response characteristics of VCSEL ensure long-term stable operation of the equipment, reduce maintenance costs, and meet high-efficiency requirements.

3. Strong anti-interference ability

VCSEL infrared light sources perform stably in complex lighting and electromagnetic environments, ensuring the reliability of security equipment under harsh conditions.
