EO LRF Camera 5km Laser Ranging Range | QJ-ETL-22
The QJ-ETL-22 is a two-axis, two-frame gyro-stabilized three-sensor EO pod, designed for compactness, lightweight operation, and industrial integration. It features a fixed-focus dual field-of-view visible light camera and a 5 km laser rangefinder. This pod is ideal for imaging, detection, tracking, and recognition of ground targets in surveillance, law enforcement, emergency response, line inspection, accident investigation, and counter-terrorism operations.
Benefits and Features
The QJ-ETL-22 delivers stable, accurate, and intelligent target detection, recognition, and tracking, even in complex environments.
High-Precision Tracking
Equipped with dual sensors and AI-assisted tracking, the pod delivers stable detection and recognition of humans, vehicles, ships, and other objects.
Electronic Image Stabilization
Two-axis gyro-stabilization and sub-pixel electronic image stabilization ensure smooth and clear imagery, even during carrier motion.
Intelligent Target Recognition
AI-assisted locking and anti-occlusion tracking provide automatic detection, recognition, and continuous tracking of multiple targets.
Remote Control & Flexibility
Supports web-based remote upgrades and dual-sensor photography/video recording for easy post-analysis and real-time operations.
