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 based camera
interface provides the functionality to request a single image, to control camera functions (PTZ,
output relay etc.) and to get and set internal parameter values. 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 description of the name for the
server, denoted with <servername> in the URL syntax description below, that is replaced with
the string myserver in the URL syntax example, also below.
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 can either be a name, e.g.,
"mywebcam" or "thecam.adomain.net" or the associated IP number for the server, e.g.,
192.168.0.220.
Syntax:
http://
<servername>
/cgi-bin/viewer/video.jpg
