Directory Structure of Image
Memory
The images are recorded in the memory with the
following directory structure.
ATA memory card (A-slot): Slot A
ATA memory card (B-slot): Slot B
Built-in memory: Drive C
Each slot or drive has the following directory structure.
A represents a folder created automatically. The
Date folder has a 6-digit folder name consisting of the
lower two digits of year (2 digits), month (2 digits) and
date (2 digits) . The Sensor 1, Sensor 2, Sensor 3 and
Act Det (activity detection) folders correspond to alarm
modes. The Timer folder corresponds to the periodical
recording mode. And, the Manual folder corresponds to
the manual mode.
JPEG image files are stored in each folder. If the digest
viewer is allowed, an HTML file (.html) and a Java
Script file (.js) are created automatically at the time of
each alarm event. For the periodical recording mode, an
HTML file (.html) and a Java Script file (.js) are created
automatically every 100 JPEG image files.

recorded in the alarm buffer with the current image size
