1. Product introduction

Door gap sight glasses can be used in narrow door gaps as small as a quarter of an inch. The user can get all the information in the room from outside the door. The camera blade is only 5mm, which is suitable for various types of door gaps. It integrates audio and video, and is a portable system that is convenient for users to control themselves. It can be slid and bent left and right. Including indoor personnel activities, obstacles placed inside the door, booby-trapped mines, etc.

        The whole system is also equipped with an infrared illumination light source and a camera with night vision, which can be used in both day and night, and can create clear images even in dark environments. It is also equipped with a high-sensitivity microphone for sound collection and monitoring, which can transmit video/audio to monitors and other devices, and the indoor images are played back on the TFT screen of the system. The instrument has a wide field of view, high resolution, and clear imaging. The ideal aid for quick hostage rescues and catching criminals.
