HD-TVI 23x Zoom PTZ Camera User Manual
DAY/NIGHT Auto-switch
The camera provides color images during the day. As light diminishes at night, it switches to night mode and delivers black and
white images with high quality. You can also switch it to NIGHT mode manually to increase the sensitivity in low light conditions.
Slow Shutter
Slow shutter function extends the exposure time to accumulate more light when the light condition is low. Thus, the image can be
brighter.
Backlight Compensation (BLC)
If the camera focuses on an object against strong backlight, the object will be too dark to be seen clearly. The BLC function can
compensate light to the object in the front to make it clear, but this causes the over-exposure of the background where the light is
strong.
Wide Dynamic Range (WDR)
The wide dynamic range function helps the camera provide clear images even under back light conditions. When there are both
very bright and very dark areas simultaneously in the field of view, WDR balances the brightness level of the entire image and
provide clear image detail.
White Balance (WB)
White balance is the white rendition function of the camera to adjust the color temperature according to the environment
automatically. It can remove the unrealistic color casts in the image.
Patrol
The camera provides up to 8 patrols. In each patrol, you can 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 causes 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.
Time Task
A time task is a pre-configured action that can be performed automatically at a specific date and time. The programmable actions
include: preset 1-8, pattern 1-4, patrol 1-4, pan scan, tilt scan, random scan, frame scan, panorama scan, day/night mode or none.
