Note: the player must be able to support transport stream packets (MP2T – suitable players
include VLC media player). Ports on different AVI NETNodes should be set to different
unique values (use even addresses for RTSP/RTP).
The source mask, internal multicast address, service name and port number are still used in
this mode.
It is possible to stream just the video elementary stream rather than the complete transport
stream. This is performed by:
rtsp://<ip_address_of_AVI_unit>/video1.sdp
This can be useful for players which don’t accept MP2T streams.
2.10 Working with Stream Recording and Playback
The NETNode Robust allows recording of the video from the AVI unit onto a micro SD card.
Files are recorded in 30 second lengths called chunks, and are stored in a compressed
transport stream format. They can subsequently be downloaded through the web browser
from the file system, or alternatively the card can be inserted into an external computer.
Files are stored in FAT16 format and thus are easily read. The date and time is always stored
in UTC format regardless of the time-zone setting.
Step 1: Insert an SD Card
To use this facility first put a 2GB micro SD card into the slot on the NETNode.
This will cause the green LED on the SD card slot to come on. The card must only be
removed when the LED is green to prevent corruption of the data on the card.
Step 2: Format the SD Card
The SD card must be formatted in FAT16 format. If not, the flash can be formatted using
Global setting Format file system button.
Step 3: Observe the File Length
This is the maximum number of files stored on the card and the oldest will be removed first.
This must be set so that the number of files does not become bigger than the capacity of the
SD card.
Step 4: Start Recording
To set the recording mode make sure the AVI unit’s video encoder is set up correctly (See
Chapter 8 Section 8 Working with the Encoder Tab ) and the video feed connected from the
camera.
1. Connect your PC to the NETNode and login.
2. Make sure the Encoder tab has been set up correctly.
3. Navigate to the Configuration tab.
4. In the Recording pane, select the Record checkbox.
5. Click the Apply button to accept the changes.
