ICR True Day and Night Auto Switch

ICR (Infrared Cut Filter Removal) True Day and Night Auto Switch is advanced camera technology designed to deliver clear, accurate video around the clock. It works by physically moving an infrared filter in and out of the optical path. As a result, the camera automatically adapts to changing light conditions. It maintains the best possible image quality in both bright daylight and low-light environments.

During daytime mode, the infrared cut filter remains positioned in front of the image sensor. Its job is to block invisible infrared light, which helps preserve natural color reproduction and prevents the image from appearing washed out or tinted. Therefore, colors stay true to life. They closely match what the human eye sees in normal daylight.

When night falls or lighting drops, the camera’s light sensor detects the reduced illumination and activates a tiny mechanical motor. This motor shifts the infrared filter away from the sensor, allowing the camera to become much more sensitive to available light. At this point, the system automatically switches to a black-and-white image feed. This improves nighttime clarity.

Without the filter in place, the sensor can capture both visible light and near-infrared illumination, such as moonlight or light from IR LEDs. This greatly enhances low-light performance and produces brighter, clearer footage in dark areas where a standard camera would struggle. Consequently, the result is more useful surveillance video. It has better detail and visibility after dark.

ICR technology also helps prevent common daytime problems caused by unfiltered infrared light, such as purple or tinted color distortion. By blocking IR light during the day and removing it at night, the camera delivers balanced performance across all lighting conditions. As a result, this makes it a reliable solution for spaces that need consistent image quality. It can be used in homes, businesses, parking lots, and entrances.

Best of all, the auto switch function works without any manual adjustment. The camera responds automatically as the sun rises and sets or as indoor lights change throughout the day. With true color accuracy in daylight and high sensitivity at night, seamless automatic switching is possible. Therefore, ICR technology provides dependable 24/7 surveillance with minimal effort.
