how far can security cameras see at night
The distance at which security cameras can see at night depends on several factors, including the type of camera, the quality of the sensor, the lens used, and whether it has infrared (IR) or night vision capabilities.
-
Infrared (IR) Cameras: Most security cameras use IR LEDs to illuminate the scene at night. These cameras can typically see in low light conditions, and some can see up to 30 meters (about 100 feet) or more, depending on the number and power of the IR LEDs.
-
Night Vision Cameras (Starlight Cameras): These high-end cameras use special sensors that are more sensitive to light, allowing them to see in very low light conditions without IR LEDs. These cameras can often see in color at night, but their range is limited to the available ambient light.
-
Thermal Cameras: Thermal cameras detect heat rather than visible light, so they can see in complete darkness. The range of thermal cameras can be much longer, often up to several hundred meters, depending on the resolution and quality.
- High-End Security Cameras: Some high-end security cameras combine IR and advanced image processing to enhance night vision, allowing them to see further and provide clearer images in the dark.
In summary, a typical security camera with IR can see up to 30 meters at night, while high-end models can see much further, depending on the technology used.
