Recording from the browser
Videos and snapshots that are recorded via the browser are saved on your computer
and not on the recorder.
Select a camera and a day to search from on the calendar displayed, and then click
Search. The timeline below the page indicates video recorded for the specified day.
The timeline also classifies by color the type of recording.
Click and drag the marker across the timeline on where you want video playback to
begin, and then click Play on the playback control toolbar. You can capture a snapshot
of a video image, save the video clips, or download the recorded video.
Dual stream recording
The recorder allows dual streaming if the camera supports it.
Dual streaming allows high quality video to be viewed in one stream (Main stream) and
lower quality video to be viewed in another stream (substream), which can be easily
streamed through a narrow bandwidth.
The normal main stream has the frame rate, quality, and resolution as configured in the
encoding menu. However, in a substream data thinning has been carried out so that it
has a lower frame rate, quality, and resolution. This allows more video to be recorded
on the HDD.
Dual streaming is available in both live and recording modes.
To select dual streaming type in playback:
