1. How do I prepare for video broadcast online?
- Internet connection with 128kbps uplink bandwidth and above
Your uplink bandwidth decides the quality of the broadcasting.
You may wish to use Webcam 1-2-3 trial and compare the video quality of different
data rate.
- Windows XP PC
- Video capture device
Note:
1. if you need to broadcast audio as well, please make sure that the audio
of you network camera is supported by NetCamCenter. WCSA440C is recommended if you need to
broadcast multiple channel of audio and video.
2. You need to enable Windows Media streaming in order to use this service.
3. If the computer is behind a firewall, please open a
port for Windows Medis streaming.
2. How do I calculate the uplink bandwidth needed for video broadcasting?
If you select 160 kbps data rate for Windows Media™ streaming, you need at least
160kbps uplink for one camera. If you have multiple cameras, you need 160kbps * the
number of camera. For example, if you wish to stream 4 cameras at the same time,
you need at least 640 kbps uplink (160 * 4 = 640 kbps). It is recommended you
have a bit more bandwidth than the bandwidth needed in theory, e.g. adding an
additional 20% to it. As in reality, a 640kbps could be less than that
because of many factors. (e.g. network traffic)
3. Do I need a web site for video broadcasting?
This requirement is optional.
If you do not have a web site, you can instruct the viewers to
watch the broadcast with Windows Media™ Player. To watch
with Media™ Player,
- Click File
- Click Open URL. Enter your camera's URL.
