this causes the over-exposure of the background where the light is strong.
Wide Dynamic Range (WDR)
The wide dynamic range function helps the speed dome provide clear images even under back light
circumstances. When there are both very bright and very dark areas simultaneously in the field of
view, WDR balances the brightness level of the whole image and provide clear images with details.
White Balance
White balance is the white rendition function of the speed dome to adjust the color temperature
according to the environment automatically. It can remove the unrealistic color casts in the image.
Patrol
The high speed dome provides up to 8 patrols. In each patrol, user is allowed to specify the scanning
track by a group of user-defined presets, with the scanning speed between two presets and the
dwell time at the preset separately programmable.
Pattern
A pattern is a memorized, repeating series of pan, tilt, zoom, and preset functions that can be
recalled with a command from a controller or automatically by a configured function (alarm, park,
time task, or power-up). By default the focus and iris are in auto status during the preset is being
memorized.
Power-off Memory
This feature allows the dome to resume its previous position or status after power is restored. By
default setting, the dome supports the power-off memory capability with the dwell time of 3
minutes.
Alarm Response Action
The speed dome supports 2 alarm inputs which can be set to NO or NC. Upon having received the
alarm input signal, the dome will automatically activate a user-defined action, which can be
programmed to: preset 1-8, pattern 1-4, patrol 1-8, pan scan, tilt scan, random scan, frame scan,
panoramic scan, color or B&W mode. After the alarm is cleared, the dome is capable of resuming its
previous activity or position.
AUX Output
An auxiliary output is a configurable signal from the dome back box that can trigger another device
to operate. The dome provides one auxiliary output. The auxiliary output type can be set to NO
(normally open) or NC (normally closed). And the alarm dwell time is configurable as well.
Manchester Code Self-test
The speed dome supports Manchester code self-test for fault diagnostic. You can enable the
Manchester code diagnosis function by setting the positions 8 and 9 of DIP Switch to ON. The
corresponding fault code will be displayed on the screen (not available during park time) while
adopting Manchester protocol.
