I am using a html script to control my old Sony SNC cameras via CGI, like this:

<TD>
<FORM ACTION="http://192.168.1.10:8080/command/visca-ptzf.cgi" METHOD=POST>
<INPUT TYPE="HIDDEN" NAME="visca" VALUE="8101040700FF">
<INPUT TYPE="image" SRC="STOP.ico" value="submit"></FORM>
</TD>

How can I edit this to control a PTZ camera that doesn't support CGI via Visca over IP?
Visca commands can't be send over http so I have to start a TCP or UDP session.
How can I do this in html and how do I implement the Visca commands?
