Slow network speed.
Appendix 2.3.5 What should I do if the Internet speed is quite slow?
The more channels opened, and the slower the video transmission speed,
therefore try to use one channel display mode when the network speed is
slow.
TIP
There may be some surplus channels that have no video input. Switching off the channels
will help to improve transmission speed. (Refer to ‘4.1 Basic Configuration’ about
switching on/off channels.)
Appendix 2.3.6 Why can’t I start Webcam server or RPB server?
Possible causes:
Other software is using these ports. If so, please change Webcam ports
configuration or stop other software.
Appendix 2.3.7 How much hard drive space do the recorded files take
up?
To use the table below, find the picture quality setting you are using and
multiply the used space figure by the number of cameras you are recording.
Divide the result into the amount of hard drive space available and you will get
the number of hours you can record on the available hard drive space.
Example using medium quality with 4 cameras with 200GB available:
48.12MB X 4 Cam = 192.48MB/HR, 200GB/192.48 = 1064 HRs = 44 days
