QJ-GFD 4K Thermal Gimbal Camera: Advanced Fixed Focus Surveillance Solution
The QJ-GFD 4K Thermal Gimbal Camera is a cutting-edge military grade EO/IR pod designed for precision surveillance. Combining 4K UHD resolution with a fixed focus thermal imager, it delivers exceptional clarity for detecting humans (2.4km) and vehicles (10km). Its robust AI surveillance camera system automatically tracks 20+ targets at ≥50FPS, even in complete darkness.
Key features include:
Dual-sensor system: 4K visible-light + 640×512 thermal imaging (8-14μm)
Autonomous tracking gimbal with ±0.3° accuracy and 60°/s movement
AI classification of 600+ objects (humans, vehicles, aircraft)
Extreme environment operation (-40°C to 60°C)
Ideal for border security, critical infrastructure protection, and UAV applications, this lightweight (260g) fixed focus thermal imager supports voice commands, VR controls, and automated patrols. The integrated AISP processor enhances image quality, while the autonomous tracking gimbal maintains lock during high-speed maneuvers.
As a complete AI surveillance camera system, the QJ-GFD enables:
✔ 24/7 all-weather monitoring
✔ Automated threat detection
✔ Seamless integration with defense systems
This military-grade EO/IR pod redefines long-range surveillance with unmatched 4K/thermal fusion and AI-powered analytics.

Object detection and small sample training based on multi-algorithm fusion: Achieving precise detection and classification of objects in common application scenarios, providing users with efficient and accurate image recognition services.
Beyond the recognition of rare objects, it can fulfill the majority of object detection and identification requirements across various military and civilian domains. This includes tasks such as firework detection, garbage patrol, detection of floating objects at sea, and inspection of military equipment.
Tracking fast-moving targets even in dark environment
Once the target is identified, the tracking algorithm continuously monitors the target’s position and movement within the thermal image. he AI adjusts the camera’s orientation in real-time to keep the target in the center of the frame, utilizing the gimbal’s 3-axis stabilization system for smooth tracking.
Strengthen the image stability by both software and hardware enhancement
When the subject becomes occluded, it estimates the subject’s movement through prediction. Based on the subject’s last known speed, direction, and movement patterns, it maintains a temporal coherence of the subject’s appearance and movement, ensuring the prediction is aligned with the expected behavior.
Each axis of the gimbal is controlled by motors that respond in real-time to feedback from the AI tracking system. This ensures that the camera can quickly and smoothly adjust its orientation to keep the subject in view, even when they move unpredictably.
Support locking targets through voice commands and digital keyboards
Easily track certain target from multiple messed targets
Each detected object is automatically assigned a unique Serial Number (SN). This SN acts as a unique identifier, similar to a label, that distinguishes each object from the others. Operators can interact with the system by typing the SN of the desired target into a user interface. Upon receiving the SN input, the system immediately switches the camera focus to the specified object, ensuring that the correct target is tracked without manual adjustment.
