Light Brightness (BL-C160 Only)
The camera features a built-in light that can turn on automatically when it is
dark, or when the camera’s motion detection or sensor features are triggered.
The following brightness levels are measured 3 m (9 feet 10 inches) from the
camera.
Directly in front of the camera: about 8.5 lx
20° to the sides of the camera: about 2.5 lx
Note that the light may not provide enough light to illuminate the
surrounding area.
Effect of Brightness and Distance on Image Quality
Distinguishing faces is difficult in the following situations.
• When the person is too far from the camera
(Generally, faces should be distinguishable up to 3 m [9 feet 10 inches] away, however, other
variables, such as shadowing, backlight, angle, etc., may affect the distance at which faces can
be recognized.)
• In the late afternoon and at night, or other times when the surrounding area is dark
• When people are moving (which causes blurring) in front of the camera
