4.2 SHUTTER (1/60

F1/100,000)
The SHUTTER speed can be selected according to user preference in the SHUTTER and
MANUAL modes. The shutter speed of 1/60 (NTSC), or 1/50 (PAL) seconds are recom
-
mended for most environments.
4.3 IRIS (OPEN, CLOSED, F16.0
a
...
a
F1.8)
The IRIS of the camera can be set to user preference in the IRIS and MANUAL modes.
4.4 AGC - Automatic Gain Control (0 ~ 30)
The AGC is automatically controlled in the AUTO, SHUTTER, and the IRIS modes. You can
have manual control over the AGC in the MANUAL mode only. This function is used to
amplify the video signal when it falls below the set parameter. Increasing the AGC level
brightens the overall screen, but a setting too high can produce noise.
4.5 DSS: Digital Slow Shutter (OFF, 2X, 4X
a
...
a
128X, 256X)
The DSS can be set to user preference under any AE mode setting. This function is used
to boost the light sensitivity of the camera by slowing down the effective shutter speed.
Increasing the DSS enhances the low light performance of the camera, but also produces
“ghosting” effect, which becomes more pronounced.
4.6 BRIGHTNESS (0 ~ 90)
The brightness can be set to user preference under any AE mode setting. The brightness
ranges from 0~90 - 0 at its darkest, and 90 at its brightest.
4.7 FLICKERLESS (ON, OFF)
Enable the FLICKERLESS mode if the screen flickers due to differences in light and
electric frequencies.
