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�

Example: request a single snapshot image
