The Nightfox 100V is a digital night vision device that emits infrared using an LED. A camera picks up infrared light and displays the image on a screen inside the viewfinder of the device. Unlike a traditional night vision device with an intensifier tube, the Nightfox can’t be damaged by sunlight and its display is colour during the day, black and white at night. Established in 2016 and based in Bristol, Nightfox has fast become one of Amazon’s top digital night vision brands with thousands of customers in over 80 countries.
