6.3.2. Digital Zoom
Digital zoom increases the view size without increasing resolution. The digital zoom
function can be used within any panel (even in full screen mode) with the following
steps:
1. Right-click the panel that zoom is required on, and select Digital Zoom to
activate the function. A picture-in-picture showing the whole screen framed
by a yellow box will appear.
2. Use the mouse scroll to zoom into the center of the image. Scrolling forward
will zoom in, scrolling backward will zoom out. Click the corners of the box
and drag to the area of interest. The main picture will show the digitally-
zoomed output, while the picture and picture will display the entire view.
6.3.3. Instant Playback
The instant playback function gives users the ability to instantly playback up to 45
minutes of video, from 20 sec to 45 min. Right-click the video panel that playback is
required on, and select Instant Play > [Time Length] to activate the function. A
popup will open with the desired playback. Time lengths available are dependent
on, and will not exceed the pre-alarm recording time set in Pre/Post Recording.
