The ObservIR LRF 35-640 Thermal & Digital Day/Night Binoculars combine thermal imaging, low-light digital vision, and laser rangefinding in one device. Designed for 24-hour use, it allows you to detect, identify, and measure the distance of your target in various light conditions.
Thermal Imaging Performance
Equipped with a 640 x 512 thermal sensor and sub-15mK NETD sensitivity, this binocular captures clear thermal images with reduced noise. It offers a 1312-yard detection range for a human-sized target and supports black hot, white hot, and red hot fusion palettes to enhance visibility in different scenarios.
Digital Night Vision Capability
The 3840 x 2160 CMOS sensor and 850nm IR illuminator deliver sharp visibility in low-light environments. The illuminator has adjustable power and beam angle with a range exceeding 400 yards, ensuring reliable image capture even in complete darkness.
Accurate Laser Rangefinding
The built-in laser rangefinder measures distances up to 1093 yards with 1-yard accuracy. This allows you to determine target range quickly and confidently.
Dual Use: Day and Night
Both the thermal and digital channels can be used during the day or at night. Thermal magnification ranges from 3x to 22x, while digital zoom offers 5.5x to 22x, providing flexible observation options in any lighting condition.

Record photos and videos directly to 64GB of internal storage, or stream wirelessly through the built-in Wi-Fi feature.
