How to change SenseCam's trigger mode settings:

example BOOT.BAT file (change file extension from ".txt to ".bat")

  1. Create a plain text file named BOOT.BAT containing the lines specifying the setting you want (see below). Note that there MUST be a single "comment line" (beginning with a #) at the end of the file.
  2. Connect SenseCam to a computer. It should be mounted as a volume.
  3. Place the BOOT.BAT file in the SYSTEM folder on SenseCam.
  4. Disconnect SenseCam from computer.

Example BOOT.BAT contents:

manual, timer-based, sense-driven camera (default):
trig 0x1F02

Sensor-triggering only:
trig 0x1C02

Timer-triggering only (uses default timer interval of GAP 30):
trig 0x0200

Timer-triggering only, using maximum rate of image capture (GAP 1):
trig 0x0200
gap 1

manual and timer-based trigger only:
trig 0x0300

only run as stationary PIR monitoring camera:
trig 0x0402

manual digital trigger only:
trig 0x0100
