5 Inch Network High-definition Speed Dome User Manual
If a bright backlight is present, the subjects in the picture may appear dark or as a silhouette. Backlight compensation (BLC) enhances
objects in the center of the picture. The dome uses the center of the picture to adjust the iris. If there is a bright light source outside of
this area, it will wash out to white. The camera will adjust the iris so that the object in the sensitive area is properly exposed.

Wide Dynamic Range (WDR)
When the Wide Dynamic Range (WDR) function is on, the dome is able to balance the brightest and darkest sections of a scene to
produce a picture that is better balanced in lighting and provides more details.

White Balance (WB)
This feature automatically processes the viewed image to retain color balance over a color temperature range. The default setting for
white balance is AUTO.

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 pattern is being memorized.

Power Loss Position
The dome supports the power loss position capability with the predefined dwell time. It allows the dome to resume its previous
position after power is restored.

Alarm Response Action
The speed dome supports 1 alarm inputs which can be set to NO (normally open), NC (normally closed). Upon having received the
alarm input signal, the dome will automatically activate a user-defined action, which can be programmed to patrol, pattern or preset
callup.

AUX Output
An auxiliary output is a configurable signal from the dome back box that can trigger another device to operate. The dome provides 1
auxiliary outputs: AUX1. The auxiliary output type can be set to NO or NC by menu. And the alarm dwell time is configurable as well.

User Management
The dome allows the users to be edited in groups with different levels of permission. In the admin login status, the user is allowed to
configure the user groups and user parameters. Multiple users are allowed to access and control the same network speed dome via
network simultaneously.
