How to see if there is a camera in the warehouse?

You can use the camera detector to see if there are cameras in the warehouse.

Close all doors and windows in the room, draw curtains and turn off all light sources in the room, so that the whole room is in a dark state. If the mobile phone doesn't have the function of filtering infrared rays, then take out the mobile phone, turn on the camera function of the mobile phone, and see everything around the house 360 degrees without dead ends (don't turn on the flash). If you can see a red dot on your phone, the place where the red dot is emitted is where the camera is. If some cameras don't have infrared function, now you need to take out a flashlight and use the principle of physical reflection to find every corner of the room and check whether there is a camera. When the power is turned off, the camera needs power to keep working. If the power is turned off, the camera will naturally not work normally.

Camera or webcam is a kind of video input equipment, which belongs to a kind of closed-circuit television and is widely used in video conferencing, telemedicine, real-time monitoring and other fields. Cameras generally have the basic functions of video shooting, transmission and still image capture. After the image is captured by the lens, the image is processed by the photosensitive element circuit and control element in the camera and converted into a digital signal that can be recognized by the computer. Then it is input into the computer through the parallel port and USB connection, and then the image is restored by software, thus forming a picture.
