Mechanical IR-Cut Filter
The camera has a built-in mechanical IR-cut filter placed in front of the image sensor to filter out infrared light in the daytime, producing better color reproduction. At nighttime or when the built-in light sensor detects low-light conditions, IR-cut filter is automatically removed to achieve better light sensitivity.
What is an IR Cut Filter?
An Automatic IR Mechanical Cut Filter blocks infrared light but allows colors visible to the naked eye to pass through. During low/no light conditions, the IR Cut Filter moves away from the lens to let in100% of the infrared light for maximum night vision performance. This results in the camera image changing to Black and White for better image quality.
NOTE: Not all Day/Night Cameras have an Auto IR Cut filter.
