Image display performance
To display camera video streams (both live images
and playback of recordings)
on your PC via the browser, the digitally compressed
data must be transmitted from the recorder to your PC
and then "decrypted". This process will take up a
different amount of processing power on your PC
depending on the camera resolution. The higher the
resolution and bit rate of the individual camera stream,
the greater the required processing power for the
decryption process.
If the number of camera streams to be displayed
exceeds the decoding power of the PC, the CPU
usage will reach 100% and operation will be slow.
Should this occur, reduce the number of cameras
to be displayed at the same time in live cast or
playback view.
The recorder web interface provides the option of
displaying a sub-stream for individual cameras in the
live image to facilitate this. This approach reduces the
bandwidth and requires less processing power for
decryption on the PC.
In playback view, the cameras are played back in the
corresponding quality of the recording (main stream).
Depending on the application and camera type, this
may mean that not all cameras can be displayed at
once. Split the cameras into different views to work
around this limitation.
System requirements
Use up-to-date PC hardware (no older than two years)
in order to ensure the smooth operation of the software
in combination with cameras and the recorder.
The requirements for your PC system increase with
the number of camera channels, as well as with the
related video resolution and bit rate of the cameras.
The camera display (resolution, bit rate and number of
channels) strongly depends on the software functions
used (live image display, playback, time of analysis).
The following table provides a starting point and
reference for the PC configuration actually required:
Minimum requirement:
Operating
system
(32-bit/64-bit)
Windows 7, Windows 8, Windows 8.1,
Windows 10
CPU
Intel Pentium 4 3 Ghz or higher
RAM
1 GB or higher
VGA
256 MB or higher
Note
Use a 64-bit operating system with 4 GB or
higher, if possible, in order to achieve optimal
performance. The following table provides the
performance data for using and selecting a
suitable CPU.
Warning
Check your PC's CPU usage when displaying live
streams or playing back recorded data using the
Task Manager (on Windows).
CPU usage < 100%
Select sub-stream
