There are many external accessories for iPhone, such as external selfie sticks, scanners, lenses, etc. You must have never seen an external device that instantly turns iPhone into an infrared night vision device. This is Night vision company Flir develops accessories specifically for Apple phones. As long as this accessory is plugged into the charging port of the mobile phone, the display will display the captured heat source information image, and its working principle is the same as a night vision device. This is a very cool add-on for Apple fans who like to play with accessories.
