Zkteco PL-852D33F-AM [7/42] Functions

 Auto brightness control

1.2 Functions.

 Control: The pan/tilt movement and zoom actions of dome can be controlled by the control keyboard, DVR, matrix, etc.

 Auto Scan: The dome provides 5 scanning modes: pan scanning, tilt scanning, frame scanning, random scanning and panorama

scanning. The scanning speed can be set by OSD menu from level 1 to 40, with the corresponding speed ranging from 1°/second

to 40°/second.

 Presets: Each of the user-definable presets can be programmed to use pan, tilt, camera settings and other settings. When preset is

called, the dome will automatically move to the defined position. User is allowed to add, modify, delete and call each preset.

 Auto Flip:In manual tracking mode, when a target object goes directly beneath the dome, the dome will automatically rotate 180

degrees in horizontal direction to maintain continuity of tracking. When the dome rotates (flips), the camera starts moving upward

as long as you continue to hold the joystick in the down position. This function can be realized by image center flip depending on

different camera models. The feature can be enabled/disabled through the menu.

 Proportional Pan/Tilt:Proportional pan/tilt automatically reduces or increases the pan and tilt speeds in proportion to the amount of

zoom. At telephoto zoom settings, the pan and tilt speeds will be slower for a given amount of joystick deflection than at wide

zoom settings. This keeps the image from moving too fast on the monitor when there is a large amount of zoom.

 Auto Focus:The auto focus enables the camera to focus automatically to maintain clear video images. In manual mode, it can

controlled by "Near" and "Far". When the PTZ moving or lens zooming, the manual mode will back to Auto fucus mode

 IR Cut Filter:The IR cut filter can be set to Auto, Day and Night. In auto mode, the camera is capable of automatically switching Black

& White mode (Night) and Color mode (Day) with regard to environment lightening conditions. In manual switch mode, user can

increase sensitivity in low light conditions by switching to Black & White mode, while the Color mode is preferred in normal lighting

conditions.

 Low Light Electronic Shutter:The shutter speed will automatically slow down in low illumination conditions to maintain clear video

images by extending the exposure time. The feature can be enabled/disabled by the menu.

 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.

 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.

 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.
