Camera Angle And Positioning
During security camera system installation, it is important to consider the distance of the camera from its subject. All the right areas should be in focus and clearly visible at all times. Avoid placing the cameras where they can be obscured by glare — this means cameras should not face direct sunlight, as too much light reduces visibility.
Security cameras should generally be installed pointing at a downward angle, unless it is a round camera such as a dome camera. If you mount a camera to a wall or structure, make sure it’s mounted properly so the camera won’t shake and distort the picture.
Do Security Cameras Work In The Dark?
Not all security cameras work in the dark. Security cameras that have low-light capabilities have a shutter that allows more light to enter the camera’s sensor. The more light that is allowed to enter the camera the brighter the image will be. However, even these low light capable cameras have digital noise that make the dark image look fuzzy. To combat this fuzzy image some security cameras come equipped with 2D and 3D digital noise reduction. Some security cameras now come with infrared light that is invisible to the human eye but can be picked up by a security camera’s sensor.
