5.4.1. Formatting
The SD card should be formatted in FAT16 format. If not, the flash can be formatted using
global setting->format file system box.
5.4.2. Recording
The set the recording mode make sure the AVI unit‟s video encoder is set up correctly and
the video feed connected from the camera. On the configuration tab->recoding pane enable
the record tick box.
The data is recorded onto the SD card in 30s chunks. Therefore the size of each chunk is the
encoded bit-rate (in bits/s) * 30 / 8. Set the maximum number of chunks to be less than the
capacity of the card over the chuck size, to prevent the data from exceeding SD card
capacity.
To check recording is taking place move to information->file system->flash card->stream
directory.
Each file is one chuck representing 30s of data. Once the number of chucks is reached, the
oldest file is deleted and recording continues providing the SD capacity is not exceeded.
