Part 2 - Configuration
Exposure Options
● AE Target Gain: Specify exposure compensation's
target gain. Exposure is compensated automatically
based on the specified target gain. Higher the gain,
brighter the images.
● Local Exposure: Activate Local Exposure. Use Local
Exposure on images that appear too dark due to
backlighting conditions and on images containing
over-exposed sections. Greater the value, clearer the
image. e.g.) Dark parking lot entrances and gas station
entrances at night (Local Exposure compensates
for the bright light coming from incoming vehicle
headlights and makes it possible to see the license
plates).
● Anti-Flicker: If the lights in the area where the
camera is located use alternating current, specify
the frequency of the lights to minimize flickering.
Matching the frequencies can eliminate flickering
completely. (NTSC: 60Hz, PAL: 50Hz).
● Slow Shutter: Activate Slow Shutter. The slow shutter
mode functions only under low lighting conditions.
When the slow shutter mode is enabled, images
are displayed bright even under the low-lighting
conditions. There may be a difference in the way it
functions depending on the camera model. See the
camera user's manual for details.
● Focus Mode: Used to change the focus movement
format as Auto/Manual/Semi-Automatic. It may not
be supported depending on the device.
● WDR: Disables or enables the WDR (Wide Dynamic
Range). When the very dark and very bright areas
exist simultaneously on the screen, WDR allows you to
recognize the both areas.

look darker. (DC-IRIS (Auto) type only)

Slow Shutter are both set to Off.

conditions and adjust the shutter speed and gain
automatically.
