QIR1975T Dual IR Thermal Sensors Object Tracking Gimbal Camera

Dual-IR thermal sensors on a single 3-axis gimbal for object tracking applications
Two separate uncooled long-wave infrared imagers (8 µm–14 µm), one with a 75 mm lens and one with a 19 mm lens, enabling long-range detection plus wider-field surveillance.
Built-in object tracking algorithm: supports deviation update at 50 Hz, tracking minimum object size, memory time for object persistence, suitable for UAV, security and defense payloads.
Gimbal stabilization and control features: pitch/tilt, yaw/pan motion, ±70° roll, smooth motion, one-key centering, supports many control interfaces (PWM, TTL, SBUS, TCP/UDP).
Multiple output formats including micro-HDMI (1080p50) or IP streaming (720p/1080p) and local TF-card recording up to 512 GB. Designed for integration in UAV and ground systems.
