A smoke camera is a kind of camera with the shape of a smoke detector, which is generally difficult to recognize, mainly for concealment. It is mostly used in more Ming-sensing places, in order not to arouse the disgust of the guests.
When the smoke concentration reaches a certain value, the weak current generated by the sensor is amplified by the amplifier and directly drives the camera or drives the camera through the action generated by the servo system, and shoots until it is burned out, so the recording equipment is best as far away from the collection site as possible.
