Geovision audio problem, what's enough bandwidth??

[deocctv 0]

Have a Gv800 4 port card with garbled audio at Web cam client also with a loud pulsating noise. Video is OK, 1 camera. I’ve done the following:

1. Connected the GV800 card to a 4 port audio extension card, by a 4 pin Molex connector.

2. Tested audio at serve, it’s OK.

3. Tried a 2nd computer, same problem.

4. In web cam setup on RPB tab I limited bandwidth to 125kb

5. Played with the gain setting in audio setup menu

6. Opened firewall in windows xp and made sure router audio port 6550 is open

The Geovision server is running on Comcast cable and Web cam client on AT&T DSL with incoming speed of about 1300 kbps. Is this a bandwidth problem, any suggestions appreciated. Played with for days & I’m at wit’s end, Thanks

Sounds like you have done everything right, from memory there is two audio codecs you can use so try the other one, Audio does not take up huge amounts of bandwidth....be carefull that your audio is not looping and causing noise IE you record ausio at site and it comes through live at speakers, but then the mike is too close to speakers so you record audio egain, causing a continuos loop which eventually wil become a booming type of noise as it builds up, to test cover or turn of mike for a few seconds.

Thanks, changed the codecs, same pulsating sound. Sounds like the alien message in the Jodie Foster movie Contact. It’s got me beat, I plan on upgrading the system soon, new computer, Geo card, AC lines etc so we’ll see what happens then. At least I know I don’t have to upgrade bandwidth. Maybe it’s best I don’t hear what my customers are saying in my place anyway.
