HI – HIT Web Server
Thousands connections
to Internet
One FTP stream
Read the entire manual on following link:
http://www.axis.com/techsup/cam_servers/tech_notes/live_video_iis.htm
HI –HIT configuration
a) Configure Web Server
Create the image directory on the Web server.
Example: c:\inetpub\ftproot\live
Create a Web Server alias (virtual directory) and use this as the image path in the Web page
Example: http://[WebServer]/live/
Get the LiveImg.dll and copy it to the "execute" directory in your Web server
file tree (typically c:\inetpub\wwwroot\cgi-bin if you are using Microsoft IIS/PWS).
b) Configure Camera to FTP transfer
HI – HIT modification of Camera stream
Change these Parameters in your HTML code:
path: The image path (i.e. /live/image.jpg).
fps | fpm: Frames/second or frames/minute.
duration: For how many seconds the images should
be pushed to the client.
timeout: The image feed stops after timeout seconds
if the image has not been updated.
Examples:
Deliver 3 images/second during 60 seconds. Stop after
30 seconds if the image has not been updated (default parameter values):
http://<web_server>/cgi-bin/liveimg.dll?path=/live/image.jpg
