The default HTTP server on the camera requires HTTP authorization (basic or digest).

IPADDR[:PORT] is an IP address:port of the camera. E.g. 192.168.1.5
PACKAGE_NAME is the name of the package. E.g. clock

Redirected to package http port.

http://IPADDR[:PORT]/local/camscripter/proxy/PACKAGE_NAME/*

Example:

http://192.168.1.5/local/camscripter/proxy/clock/test.cgi

Redirected to package http public port.

http://IPADDR[:PORT]/local/camscripter/proxy_public/PACKAGE_NAME/*

---
