FNIRSI NVS-20 Digital Night Vision Device with 4K HD Recording

The FNIRSI NVS-20 is an advanced digital night vision system designed for high-resolution imaging and recording in both daylight and complete darkness. It supports 4K video recording and captures still images at up to 36 MP resolution, providing detailed visual documentation for outdoor observation, research and field operations. The device integrates a dual day/night imaging system with an 850 nm infrared illumination source, offering adjustable IR intensity across seven levels to adapt to varying environmental conditions. In total darkness, it enables observation distances of up to approximately 300 meters, while in daylight it operates without range limitations.

The optical system includes a 6x digital zoom function combined with a precision manual focus control, allowing users to accurately adjust image clarity and magnification without significant loss of detail. A built-in 1.54-inch IPS display enables real-time viewing as well as playback of recorded photos and videos, supporting efficient on-device review and documentation.

The NVS-20 is designed with a compact, ergonomic housing that allows comfortable one-handed operation in field conditions. It includes a silicone lens hood for protection against glare and environmental impact, as well as a standard tripod mounting interface for stable stationary recording during extended observation sessions.

Power is supplied by a replaceable 18650 lithium battery, providing up to 8 hours of operation in standard mode and approximately 4 hours with active infrared illumination. The device includes 32 GB of internal storage for recording and supports data transfer via USB-C, enabling easy export of captured media to external devices. Multi-language interface support enhances usability across different regions.
