LY-BT75

Five-Channel Binocular Observation System

An all-weather long-range binocular platform integrating thermal, low-light, visible-light, laser-ranging, and positioning channels.

Product overview

LY-BT75 supports border and coastal surveillance, patrol, long-range search, and rescue missions by combining 640 × 512 thermal imaging, 800 × 600 low-light imaging, 1920 × 1080 visible imaging, 1535 nm laser ranging, positioning, and a digital compass in one handheld or tripod-mounted system. Image fusion, photo and video capture, Wi-Fi, and remote control support continuous detection, confirmation, and reporting in day, night, and low-visibility conditions.

Feature guide

Five-channel coordination

Thermal imaging detects heat signatures in darkness, low-light and visible channels add target detail, and laser ranging with positioning data supports range confirmation and target cueing.
