Zoom

You can use the zoom function if there is an area or object in the viewer that you want to zoom in and look at in more detail.

There are two different types of zoom:

Digital zoom:

  • The image is cropped and resized to the pixel size of the original image to zoom in on the required image area.

  • The quality of the image gets lower.

  • The use of the digital zoom is not reflected in the recording.

Optical zoom (only for PTZ cameras):

  • The camera lens physically moves to zoom in on the required image area.

  • The quality of the image does not change.

  • The use of the optical zoom is reflected in the recording.

Use Optical Zoom

The optical zoom is activated when you have selected the telecontrol mode in the toolbar. It works only in live mode. Your camera must support this features.

If you use the optical zoom on your camera while recording, the zoom levels used will be reflected in your recording.

The Area Zoom and Click to Move features only work with the following PTZ cameras and the respective IP camera plugins:

  • Axis

  • Bosch

  • G-Cam/E3

  • G-Cam/E4

  • G-Cam/E5

  • GNSD

  • Samsung

  • ONVIF

  • Hanwha cameras connected via the ONVIF plugin

    Some Hanwha cameras support Area Zoom via their own API, but not via ONVIF. To use the Hanwha Zoom in the ONVIF plugin, select the plugin in the Hardware module list and open the Advanced settings tab using the shortcut Ctrl + Alt + R. Change the following values:
    - system.ONVIF.UseHanwhaAreaZoom: Set the value to True.
    - system.ONVIF.HanwhaAreaZoomChannelID: Enter the Channel ID. For single PTZ cameras, this is usually 0. For multihead cameras, you must enter the correct channel ID. You can find this in the web interface of the camera. The IDs usually start with 0, i.e. channel 1 has the ID 0 and so on.

  2. Right-click on the specific position in the viewer. The camera moves to this position and centers it.
