Our take on the FNIRSI NVS-20 4K HD Monocular Night Vision Device Infrared 6x Digital Zoom

The FNIRSI NVS-20 is a handheld digital night vision monocular with a 25mm objective lens, a 1.54-inch IPS color screen and infrared illumination for viewing in weak light or total darkness. It records 4K video and stills to a TF card, plays them back on the device and exports files over USB, and it offers up to 6x digital zoom. It suits campers, wildlife watchers, boaters and property owners who want an affordable recording night scope rather than a Gen 2 or thermal unit. Against analog night vision it adds recording and a color screen but relies on digital zoom and IR, so image quality in deep dark is grainier than pricier digital rivals with larger sensors.

What reviewers say

  • 4.7 / 524 ratings

Owners rate it highly overall, treating it as a capable budget night vision monocular that records video and is simple to carry. They like the daylight-to-dark flexibility and the IR reach for the money, while noting image grain at long range and short battery life.

Questions and answers

How far can it see in total darkness?
FNIRSI rates the infrared range at up to 300 m in full dark. In practice, recognition fades well before that, and the IR illuminator works best on nearby subjects.
Does it work in daylight?
Yes. It has a color mode for day use and switches to infrared for low light and darkness, so it doubles as a spotting scope.
What is included in the box?
The monocular, a USB-C charging cable and a carry strap are the usual contents. A TF card and a spare 18650 battery are not included, so add both.
Is the 6x zoom optical?
No. It is electronic zoom, which crops and enlarges the sensor image, so expect softer detail at high magnification.
Can I record and transfer video?
Yes. It records 4K video and stills to a TF card and exports files over USB, and the card slot also supports firmware updates.
How does it compare with thermal night vision?
It is far cheaper but needs infrared light and cannot detect body heat. Thermal units see heat signatures through total darkness and light foliage but cost much more.
Where is the FNIRSI NVS-20 4K HD Monocular Night Vision Device Infrared 6x Digital Zoom cheapest?
At FNIRSI, for $49.99, as of our latest check.
