URL Commands for the Network Camera/Video Server

Overview

For some customers who already have their own web site or web control application, the Network

Camera/Video Server can be easily integrated through URL syntax. This section specifies the external

HTTP-based application programming interface. The HTTP-based camera interface provides the

functionality to request a single image, control camera functions (PTZ, output relay etc.), and 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, text within angle brackets denotes content that

is to be replaced with either a value or a string. When replacing the text string, the angle brackets

should also 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 further down in the page.
URL syntax is denoted with the word "Syntax:" written in bold face followed by a box with the referenced

syntax as shown below. For example, name of the server is written as and 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:" in bold face followed by the returned data in a box. All data is

returned in HTTP format, i.e., each line is separated with a Carriage Return and Line Feed (CRLF) printed as \r\n.
Return:

HTTP/1.0 \r\n

URL syntax examples are written with "

Example:" in bold face followed by a short description and a light grey box

with the example.
Example: request a single snapshot image
