SMT18SQ6 is our mature product that integrates a 18x optical zoom camera, a 640x480 thermal imaging sensor, and a high-precision 3-axis stabilizing ball-type gimbal. It adopts high-precision FOC encoder and it is characterized by high stability, small size, light weight, and low power consumption. The camera supports visual and infrared imagining. Its low light level sensor has 4,000,000 effective pixels and the thermal imaging sensor adopts a 640x480 resolution non-guard sheet imaging detector imported from America. Besides, it provides real time picture-in-picture(PIP) displaying function in HDMI videos and allows storing their data in local TF card. More practically, it is very convenient for users to do switch among different PIP displaying modes without interrupting data transmission(visual&infrared images) and zoom function.
