URL Commands for the Network Camera

1. 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.

2. 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 <servername> 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 <servername>
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://<servername>/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 <HTTP code> <HTTP text>\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
http://mywebserver/cgi-bin/viewer/video.jpg
