index.dat format

The index.dat file is an array of these structures:

struct BIDBindex
{
QWORD record; // database offset for associated clip
QWORD utc; // start time with msec resolution
DWORD msec; // duration

DWORD flags;
DWORD camera; // camera serial number

BYTE balert;  // true/false
BYTE extension[3];  // the associated clip's file type
};

All authenticated web server users can download index.dat from the web server via /db/index.dat. Admin privilege is required for other files in that folder.
