How IR-cut works in an IP camera - Get the scoop
IR-cut can be powerful, but what does it actually do? Find out how to take advantage of this special IP Camera feature.
What does IR-cut do?
IR-cut (Infrared cut-off filter) is a mechanical shutter design. It is placed between the lens and the image sensor, and is controlled by a motor or an electromagnet.
It is designed to block or deliver the infrared in order to provide a true color reproduction high-quality image at day and night.
What is infra-red?
Infrared, which spans 700nm to 1000nm on the EM spectrum, is beyond what the human eye can see, but the IP camera sensor can detect it and make use of it.
How does IR-cut work?
During the day, the IR filter is switched on. It will block infrared and only allow visible light to pass through. This ensures it does not distort the image colors, generating true color representation – exactly as the human eye sees them.
In the night (or in low-light conditions), the IR filter is switched off so IR and all other forms of light will be allowed to reach the sensor (CCD/CMOS). The image sensor can absorb sufficient light and the camera will turn to black-and-white mode, which is more sensitive to infrared.
