7.2 factors influencing system capability
You muse consider the whole system capability issue, factors influencing your system
and system optimized settings when you set up your system. Bandwidth including
stream rate setting, frame rate, and too many client connections influencing frame
rate is the main issue that we need to consider.
Following are the common factors that will influence the server efficiency that we
need to concise:
Firstly is your bandwidth. Generally in LAN the bandwidth is not a problem but we must
consider the upload bandwidth in WAN or some private networks. If the upload
bandwidth is 513k or lower, you would better set the output stream of server within 512k,
otherwise there the video or audio will not play fluently.
We must emphasize the ADSL. Usually we are considering the download bandwidth of
ADSL, but in the Network Camera application, we are using its upload bandwidth. Thus
at this point we have to concern about the upload bandwidth for the system design,
for example, for an ADSL with 1.5M download bandwidth, the upload bandwidth is less
than 512k. Thus the upload bandwidth is what we have to concern about mostly for
network design.
About the image parameter setting according to network please refer to
“ image
advanced setting ” in “ image setting ”
Too many clients viewing from a Network Camera will influence the server capability
cause the frame reducing. Consequently, we recommend that the maximum viewing
connections is 20 channels.
Capture function provided by Network Camera is using the front-side high definition
image capture method. Frequently capture will influence the server capability and
cause frame rate reducing.
Too much network load will influence the system capability and cause the audio and
video playing not fluently.
CPU capability insufficiency will cause the audio and video playing not fluently.
Wireless transmission will cause the disconnection and server re-connection from client
due to the unstable
of wireless network.
8 Speed Dome Operation
Check Proceedings before Operation
√
Check the cable connection carefully before input power.
The camera ID of the controller must be identical to that of the target camera. The camera
ID can be identical by reading DIP switches in the camera.
√
Since Preset 95 is reserved to start the OSD menu, this can not be used as regular Presets.
Therefore, the description of “ Preset 1~128 ” always means excluding preset 95 in this
manual.
