Handleiding

a. Shutter is used to control the light that comes into

the lens. A fast shutter speed is ideal for scenes in

quick motion. A slow shutter speed is ideal for

scenes that change slowly.

i. You can set a shutter speed when

Exposure Mode is set to Manual or

Shutter Priority.

ii. If Slow Shutter is set to Off, the

reciprocal of the shutter speed must be

greater than the frame rate.

B. Gain (dB)

a. Control image signals so that the camera outputs

standard video signals according to the light

condition.

i. You can set this parameter only when

Exposure Mode is set to Manual or

Gain Priority.

C. Slow Shutter

a. Improves image brightness in low light conditions.

i. You can set this parameter only when Exposure Mode is not set to Shutter Priority and when

Image Stabilizer is disabled.

D. Slowest Shutter

a. Set the slowest shutter speed that the camera can use during exposure.

i. You can set this parameter only when Slow Shutter is set to On.

E. Compensation

a. Adjust the compensation value as required to achieve the desired effects.

i. You can set this parameter only when Exposure Mode is not set to Manual.

F. Metering Control

a. Set the way the camera measures the intensity of light.

i. Center-Weighted Average Metering: Measure light mainly in the central part of images.

ii. Evaluative Metering: Measure light in the customized area of images.

iii. Highlight compensation: Ignore the brightness of the overexposed area of images. But selecting

this setting will decrease the overall brightness of the image.

iv. You can set this parameter only when Exposure Mode is not set to Manual.

G. Day/Night Mode

a. Automatic: The camera outputs the optimum images according to the light condition. In this mode,

the camera can switch between night mode and day mode automatically.

b. Night: The camera provides high-quality black and white images using the existing light

c. Day: The camera provides high-quality color images using the existing light.

d. Input Boolean: The camera switches between day mode and night mode based on the alarm input.

H. Day/Night Sensitivity

a. Light threshold for switching between day mode and night mode. A higher sensitivity means that the

camera is more sensitive to the change of light and becomes more easily to switch between day mode

and night mode.

i. You can set this parameter only when Day/Night Mode is set to Automatic.

I. Day/Night Switching(s)

a. Set the length of time before the camera switches between day mode and night mode after the

conditions for switching are met.

i. You can set this parameter only when Day/Night Mode is set to Automatic.

J. WDR

a. Enable WDR to distinguish the bright and dark areas in the same image.

i. You can set this parameter only when Exposure Mode is set to Automatic, Indoor 50Hz, Indoor

60Hz and when Image Stabilizer and Defog is disabled.

K. WDR Level
