Surveillance IP camera have increasingly entered people’s field of vision, and their use in family life has become more and more everyday. But where should it be selected when it is installed, this still needs to be understood by ourselves. It would be bad if it would affect the recording effect. The editor told you what light is best.

Smart Waterproof IP Camera.

Forward light means that the direction of light irradiation is consistent with the direction of the field of view of the surveillance IP camera. The front of the person receives light uniformly, without shadows, and the color reproduction is normal. However, if the light is too strong, the surface level of the subject will be seriously lost. Backlight is the opposite of forward light. The projection direction of the light is opposite to the shooting direction of the surveillance camera. Its main modeling characteristics are that the front of the subject’s subject is not illuminated by light. Total loss, darkened face, and inability to recognize portrait features.

Side light is more common, and most of the side light environment is indoor installation. Side light is the direction of light irradiation on the side of the subject. This kind of light makes the subject half bright, half produces shadows, the dark part of the character will be lost, the surface of the character has a strong contrast between light and dark, and the color reproduction is acceptable.

When installing indoors, try to avoid choosing the installation location that causes backlight. If you can’t avoid it, you can use a wide dynamic surveillance IP camera to increase the light source. It should be noted that the contrast between the illumination of the front of the portrait subject and the illumination of the background when the backlight is strong is much larger than that of any existing wide dynamic surveillance camera. The implementation of most wide dynamic surveillance camera technologies enhances the details of the face, but cannot compare the imaging levels and details in a down light environment. So the choice of these three is very important.
