Classification of infrared surveillance cameras:

Infrared cameras are the kind of cameras that are monitored 24 hours. Categories: ordinary infrared camera and lattice infrared camera. The dot array infrared camera is better than the ordinary camera, the distance of exposure is far, the painting quality is fine and clear, and the service life is longer than that of ordinary infrared. Infrared camera is sensitive to infrared, in a certain band range, such as 800nm-1100nm. If it is spectral, it is similar to the principle of common camera. The principle of infrared camera is that infrared light radiates objects, diffuse reflection, is received by the surveillance camera, and forms video image.

Different ways of avoiding infrared cameras:

If that’s the only way, it’s impossible. Unless you have a reclusive. If there are other options, please bypass.

If you don’t have to choose, first look at whether the camera is a ball camera or a gun camera. The spherical camera is generally wide-angle, and the gun camera is usually a long barrel. The spherical camera can take a wide-angle picture, basically can see the whole road condition, the picture is relatively clear, but the picture takes the character far away from the picture is not very clear, you can walk a little away from the camera edge corner, so that the proportion of your shooting in the whole picture is small, not very clear, of course, it is impossible to see you completely. If it is a gun camera, the image of the camera is clear, but only local picture, you can try to squat down or walk by the corner of the wall on the side of the gun camera. In this way, the gun camera takes a far away part picture, which is unlikely to see you pass.

In addition, the camera is turning black and color in the dark. After the red light is on, the image is black and white, but the face can be seen clearly. Except for the light source of the red light is too strong, it will cause the face to be too bright and white.

Blind area of surveillance camera:

The blind area of the monitoring camera is indeed present. In fact, the monitoring camera is like the eye. When the user is standing, the position under the foot is invisible, so the blind area of the monitoring camera also exists. Generally speaking, the blind area of the monitoring camera is about one square meter below the monitoring camera.

Generally speaking, the smaller the number of surveillance cameras, the smaller the blind area exists. In such cases, a camera can be installed directly opposite the camera, so that there will be no dead angle. This can also directly install a panoramic camera not only can rotate or dead angle.

Correct method of avoiding infrared camera:

Normally, infrared camera infrared light has the function of face recognition through mask. In the face of high-performance infrared cameras, you need to use infrared cut-off masks to ensure your privacy. For the ordinary ordinary unethical face recognition to grab infrared camera, using privacy glasses is a low-key method that is not attracting attention.
