Long-Range EO + LWIR Thermal + Laser Rangefinder Surveillance System | ETL-255

The ETL-255 is a long-range electro-optical surveillance system integrating a high-zoom visible camera, a long-wave infrared (LWIR) thermal imager, and a precision laser rangefinder. Designed for airborne and ground-based monitoring platforms, it provides reliable target detection, identification, and tracking in both day and night environments.

The visible imaging module features a 1920×1080 resolution camera with a powerful 55× optical zoom lens (4.25–234 mm), enabling wide-area observation and long-distance target identification with vehicle detection up to 25 km. The LWIR thermal imaging module operates in the 8–14 μm spectral band with a 640×512 sensor and a 20–120 mm zoom lens, providing stable thermal detection in darkness and low-visibility conditions.

The integrated 1535 nm laser rangefinder measures distances up to 9 km with high ranging accuracy and supports multiple measurement frequencies. Combined with a stabilized 360° gimbal platform and intelligent target tracking capability, the QJ-ETL-5569 delivers stable imaging and accurate long-range monitoring for applications such as border surveillance, maritime security, reconnaissance, and infrastructure protection.
