Files to Make a Backup
Storage Location of Video Data, Audio Data, and Event Data
Video data being recorded is saved in a temporary file (refer to “About Temporary File”
below), and the file is settled and saved as video data when its size reaches 1 GB (by
default) to the storage drive.
Audio data is recorded using the G71 µ Law format, and saved in the QuickTime file
format. The audio recording bitrate is 64 Kbps.
The recorded video data, audio data, and event data are saved in the following folders
according to your settings for Save video in and Drive when you register Camera Servers
(➝ P. 98).
