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 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 followed by a box with the referred syntax as seen
below. The name of the server is written as . 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:///cgi-bin/viewer/video.jpg
Description of returned data is written with "Return:" followed by the returned data in a light grey
box� All data returned as HTTP formatted, i�e�, starting with the string HTTP is line separated with a
Carriage Return and Line Feed (CRLF) printed as \r\n�

URL syntax examples are written with "Example:" followed by a short description and a light grey
box with the example�

General CGI URL syntax and parameters
CGI parameters are written in lower-case and as one word without any underscores or other
separators� When the CGI request includes internal Network Camera parameters, the internal
parameters must be written exactly as they are named in the Network Camera or video server� The
CGIs are organized in function related directories under the cgi-bin directory� The file extension of
the CGI is required�
