Câmara de visão noturna digital Fnirsi NVS-20 com gravação 4K-HD — gravador portátil de mão

NVS-20 is a compact 4K HD digital infrared night vision camera with a 36 MP CMOS sensor and an integrated professional video processing chip. It provides clear images in low-light and nighttime conditions, supports up to 6x digital zoom and uses an 850 nm infrared lamp with six settings to adapt illumination. The camera includes a rechargeable 3.7 V lithium battery and a built-in memory card for straightforward export of recorded material.

Advantages

The camera delivers high-resolution 4K imaging from a small, lightweight body and combines a high-resolution CMOS sensor with professional video processing for improved image clarity. The 6x digital zoom and adjustable 850 nm infrared illumination extend observation range in darkness up to the device's specified limits, while a rechargeable lithium battery and built-in storage simplify mobile, outdoor use.

How to use

Charge the built-in 3.7 V lithium battery via the USB Type-C port before use. Turn on the camera, select the desired infrared illumination level (one of six settings) according to ambient darkness, and use the 6x digital zoom to frame distant subjects. Recordings are saved to the built-in memory card and can be exported by connecting the camera to a computer via USB Type-C or by removing the memory card if accessible.

Recommendations

For best nighttime results, set the infrared illumination to a lower setting when subjects are nearby and increase the level for more distant scenes. Avoid pointing the infrared lamp directly at reflective surfaces to reduce glare and ensure the battery is fully charged for extended outdoor sessions.
