15 Image Transmission
The device can be congured as an active network element for the continuous transmis-
sion (streaming) of the produced video data (see section “Video Server” on page 49).
In addition, the device, as a passive network element, can be triggered for transmission of
video data via various transport and data protocols by external devices and applications.
15.1 Web Browser
Current video data can be requested as a single image (JPEG) by any web browser.
Transmission protocol HTTP
Transport protocol TCP
Port 80
Note that
• the used encoder must be congured for MJPEG encoding.
• the used encoder must be enabled.
• the JPEG live access right/permission must be enabled.
Use the following URL request for the various encoders:
Encoder 1 http://IP address of the device/live/image0.jpg
Encoder 2 http://IP address of the device/live/image1.jpg
The displayed image can be refreshed at any time. The URL request can be integrated in
an HTML (JavaScript) page that refreshes the image automatically.
15.2 RTSP Application
The live video can be actively requested and controlled (start and stop) by external RTSP
capable applications. For more information, refer to section “RTSP” on page 53.
Communication protocol RTSP
Transmission protocol RTP
Transport protocol UDP/TCP
Port 554
Note that
• the used encoder must be enabled.
• the RTSP server in the camera must be enabled.
• the RTSP live access right/permission must be enabled.
