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

Description of returned data is written with "Return:" in bold face followed by the returned data

in a 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.

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.
