Operation

7.1 Glossary
Alarm Linkage
This dome camera supports four switch alarm inputs, one switch output and one digital output. The
camera starts running a preset action as soon as it detects an alarm signal.
Auto-Adaptive to Protocol and Module
This dome camera will automatically adapt to the available protocol.
3D Allocation
The user can move the image of an area to the centre.
Privacy Masking
In monitoring mode, a zone the user is not willing to display can be set as a privacy-protected area.
Pattern Scan
The scanning pattern can be saved into the memory. This camera has 4 path patterns. Each path can
record 512 different instructions (during max. 15 minutes).
Zero Alignment
The zero point is that point to which the camera returns after operation.
Auto Flip
In manual scanning mode, when driving beyond the maximum tilt angle, the camera will automatically
rotate 180° in horizontal direction to maintain scanning continuity.
Focus
The auto focus enables the camera to maintain a clear image. The camera will not automatically focus in
following conditions:

The target is not in the centre of the screen.

Attempting to view images that are far and near at the same time.

The target emits a strong light, e.g. a neon lamp.

The target is behind a windowpane covered with droplets or dust.

The target is moving quickly.

The target is too dark or faint.
Back Light Compensation (BLC)
If the background light is bright, the target in the picture may appear dark. The BLC enhances exposure of
the target in the centre of the picture. The camera adjusts the iris according to the centre of the picture.
Iris Control
Default is automatic camera aperture. The camera senses changes in ambient light through moving and
automatically adjusts the lens aperture to make the output image brightness stable.
Ratio Speed
Intelligent pan and tilt speed is variable and depends on the zoom factor. When zooming in, the speed
will decrease; when zooming out, the speed will increase.
360° Scan
The camera continuously scans the scene at the set speed in horizontal direction, provided that the pitch
angle remains the same. In scanning status, the operator can move the joystick to exit the scanning mode.
Preset
After the camera keeps an arbitrary PTZ location, it will automatically move to the defined position when
the preset is called.
Guard Tour Scan
The camera scans according to a certain edited preset order.
Limited Points Scan
The camera scans at a certain speed between the set left and right points. The range between these two
points is 20° to 340°.
