Hi there :) Thanx for your script and your time/work Andrew Hazelden

Unfortunately this script does not work correctly on ixus 220 aka elph 300hs.

"There appears to be an issue where the motion detection function doesn't reset for the next photo unless the image review mode is disabled. To disable the image review feature, open the main Canon menu by pressing the menu button on your camera. Scroll down to the option labeled Review and set it to Off."

Even if I set review to OFF. The problem persist.

I have the lastest stable build: ixus220_elph300hs-100c-1.0.0-1892-full_ALPHA

Hi Frojnd.

I'm interested in hearing more about the Motion Detection Plus script issue on the Canon IXUS 220 camera. Could you describe what happens when you try to run the script? Does the software get stuck in a continuous photo taking loop?

Regards,
Andrew

Hi Frojnd.

It appears the issue you are experiencing is due to the script's motion detection "trigger sensitivity" threshold. I have an updated script that has a lower default sensitivity and provides control over the parameter.

After I run a camera test on my lawn for a day to make sure it works I will post the improved script.

Hi andrewhazelden,

When I try to run the script, the grid naturally shows up and then whenthere is a change in a position, in my case it was rather coludy and script recognized the movement of the clouds and start shooting. But it shoots every n seconds (I don't know how many seconds n was exactly)...

I think the software gets stuck in a continuous photo taking loop.

I'd be more then glad to try new version :) I wasn't able to actually shoot any light burst with this camera and your script has the most potential :)

Hi Frojnd.

I have created Motion Detect Plus v0.2.

This upgrade adds a "Motion Threshold" parameter that lets you control the responsiveness of the motion detection feature. If the camera to takes photos continuously increase the "Motion Threshold" setting for a reduced motion detection response.

Here are several typical motion threshold levels:
12=Sun 24=Cloudy 36=Dawn/Dusk

I would like to thank Waterwingz for his help in troubleshooting the issue.

Today I released version 0.3.1 of the Motion Detect Plus Script.

You can download the CHDK Motion Detect Plus script here:
chdk-motion-detect-plus.zip

This version improves the script by reducing the continuous photo issue and adds a "Number of Shots" attribute that takes multiples shots during a motion detection event.

@andrewhazelden :  I can't believe that I have not suggested / requested that you make a wiki page out of this thread. The first posting is especially great stuff and when I finally get my "Best of the Wiki" page done, this one would be near the top.

Hi Waterwingz.

Thanks for the suggestion of adding the Motion Detect Plus script to the CHDK Wiki. When I get a moment I will write up a new wiki page with the latest info.
