*Pre-requisites: HTTP CGI server setup.
*Pre-requisites: SMTP server / HTTP CGI server setup.
Send URL commands
URL commands can be sent to HTTP CGI servers upon event. This provides the possibility of
highly intelligent response upon event. IP devices and many other devices also have embedded
CGI servers that may be controlled.
When Event Handler sends an URL command, it will send one set of command when the event is
trigged, and another as the event becomes inactive. Depending on the CGI design, the URL
commands may be able to be stringed together, and multiple commands may be issued in a
single line.
An example would be when the access control device at the entrance detects an entry, this
device provides a DI signal to the PTZ device, and triggers an event. This event then sends a
loopback command to the PTZ Device itself (by setting its own IP as the HTTP CGI server). The
PTZ Device then moves to a preset location, stays until the event is over, and then moves back to
another location. At the same time it moves to the pre-set location, it increases the bitrate from
1M to 3M, and the frame rate from 4 fps to 8 fps. The bitrate / fps changes are reverted at the end
of event.
