(Automatic Exposure) mode to have the camera automatically set
the shutter speed and/or aperture value to match the brightness of

AE-DSS
[Except for 18X PTZ cameras]
Function:
Enable/disable the DSS capability, and set the digital
slow shutter.
The digital slow shutter (DSS) slows the picture frame
rate and enhances the camera's sensitivity in poor light
environments. Light sensitivity improves as the value of
DSS increases.
Option: AUTO -
(default) auto digital slow shutter function
The classification of manual DSS is relating to the
formats of the High-speed PTZ cameras.
Under the PAL format, the range could be adjusted as follows:
1/1.5, 1/3, 1/6, 1/12, 1/25, 1/50
Under the NTSC format, the range could be adjusted as follows:
1/2,1/4,1/8,1/15,1/30,1/60

PTZ camera.
SHUTTER
Function:
Select the shutter speed-priority AE mode, and set a
suitable speed.
Once a shutter speed is set, the camera will
automatically select an aperture value to match the
brightness. Faster shutter speeds allow the camera to
capture instantaneous streak-free images of a moving
subject, while slow speeds improve light sensitivity in
poorly illuminated areas.
