A530 Going to "Sleep" after Few Mins. w/MD?

Loaded all-in CHDK software to get my Canon A530 acting as a security camera with motion detection. The MD works fine, but if there's no movement, the camera "goes to sleep" until I flip from Recording to Playback. It won't take a picture--even manually--but the lens stays extended and the green light is on, so it's not really completely powered down. Very frustrating. Turned off Auto Shut-0ff and am running it on AC power. Any ideas?

I believe your camera enters power saving mode (different from auto shutdown) in which it disables the LCD and the sensor. Motion detector obviously won't have an input image to work with when the sensor is shut down. Thsi is easily fixed.

Set CHDK menu -> miscellaneous -> disable LCD off: alt (or script)

to make CHDK prevent this power saving mode. The reason you can't shoot in this mode is probably because you didn't remember you are in CHDK ALT mode while running this script... to verify, you can of course press alt to pause the script and then attempt to shoot (or full press shutter to interrupt the script, then press ALT to exit ALT mode and then shoot).

Fudgey,

Thank you for advising, but the camera still seems to "sleep" even when "disable LCD Off" is set to "Alt" (which I just tried) or "Script" (which is what it had been set on previously). Very frustrating. Any additional thoughts?

Does this happen in both slow and fast modes using the MDFB script? The fast mode waits for motion with shutter half pressed which alone should probably be enough to prevent power saving (I'm not sure about that, though).
