B. URL commands of the Network Camera
Overview
For some customers who already have their own web site or web control application,
Network Camera/Video server can be easily integrated through convenient URLs. This
section specifies the external HTTP based application programming interface. The HTTP

The image and CGI-requests are handled by the built in Web server.
Style convention
In URL syntax and in descriptions of CGI parameters, a text within angle brackets
denotes a content that is to be replaced with either a value or a string. When replacing
the text string also the angle brackets shall be replaced. An example of this is the

URL syntax' are written with the “Syntax:" word written in bold face followed by a box
with the referred syntax as seen below. The name of the server is written as
<servername>. This is intended to be replaced with the name of the actual server. This

http://<servername>/cgi-bin/viewer/video.jpg
