How Do Night Vision Security Cameras Work?

Night vision security cameras using infrared (IR) light to see in the dark. IR LEDs emit invisible light that the camera can capture, allowing for clear footage and dependable surveillance even in low-light or no-light conditions. While many night vision cameras rely on IR LEDs, some also use spotlights to illuminate the area and improve visibility.

However, not all night vision cameras are created equal, and different types of cameras employ different technologies to achieve the same goal.

For example, IR cameras typically have multiple built-in IR LEDs surrounding the lens, while spotlight cameras can provide even better night vision capabilities. Additionally, many IR security cameras include an IR cut filter that enables them to detect ambient light and adjust their settings accordingly for greater clarity and color during the day.
