What is the function of a day/night camera?

A day/night camera is designed to enhance surveillance capabilities by adapting to varying lighting conditions. The key feature of this type of camera is its ability to switch automatically between color recording during daylight and black-and-white recording in low-light or nighttime situations. This automatic transition is crucial as it allows for optimal imaging depending on the available light, providing clear and usable footage both during day and night.

The technology behind day/night cameras typically includes the use of specialized sensors and filters that enable this transition without needing manual intervention. This ensures that the camera can seamlessly adjust to changes in lighting without requiring user input, making it highly effective for continuous surveillance.

Other options suggest limitations or specific features that do not accurately reflect the capabilities of a day/night camera—such as only recording at night, requiring manual mode changes, or functioning solely in low-light conditions. These characteristics do not represent the intended versatility and efficiency of day/night cameras in surveillance applications.
