Appendix

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
