What is the function of an IR-cut filter in Axis cameras?

The function of an IR-cut filter in Axis cameras is to block infrared light during the day, allowing only visible light to pass through. This process enhances image clarity and color accuracy in daylight conditions. By filtering out infrared light, the camera avoids potential color distortions that could occur if infrared light were present in the scene, which is particularly important for producing vibrant and true-to-life images during the day when natural sunlight is available.

At night or in low-light conditions, the IR-cut filter typically opens up, allowing infrared light to enter, which is utilized by the camera's IR-sensitive sensors for improved visibility in darkness. This capability enables Axis cameras to maintain effective functionality across varying lighting conditions, providing clear images both during the day and at night. The design and operation of the IR-cut filter are crucial for applications requiring consistent image quality and accuracy throughout the 24-hour cycle.
