FNIRSI NVS-20 digital night vision device with 4K HD recordingThe FNIRSI NVS-20 is an advanced digital night vision device that can record 4K high-definition video and take 36 MP quality images - both day and night. With a built-in day/night mode, adjustable 850-nm infrared illumination and a 7-level IR power scale, the device provides excellent visibility in all conditions. In total darkness you will observe objects up to 300 meters away, and in good light - without limitations.Zoom in without losing qualityWith a digital zoom of up to 6x, you can easily zoom in on any detail without losing focus. The lens' precision focus dial allows you to quickly get a clear image, regardless of distance. You can not only record everything you see, but also play it back with the function of previewing recordings and photos on the built-in 1.54-inch IPS screen.Compact and functionalThe NVS-20 is a device with a smart, compact design. It fits in the palm of your hand, making it lightweight and comfortable to use with one hand. A silicone lens hood protects the lens, and a tripod-mounting thread allows stable positioning of the equipment, making it easy to take photos and recordings in the field.Long runtime and easy operationPowered by a replaceable 18650 lithium battery, the night vision device operates for up to 8 hours without IR and up to 4 hours with active IR illumination. The built-in 32GB memory card allows you to store a large amount of recorded footage, which can be easily transferred via USB-C port to a computer or other device. So you can conveniently share captured moments in the wilderness with family and friends.Ready for any challengeThe FNIRSI NVS-20 is the perfect companion for camping, nighttime wildlife observation, field exploration and scientific research.
