Motion sensor trigger ...

Hmmm, the problem might be the other way around, they work at night but no idea if it could be swapped to daylight. Hadn't thought about that.

I think it's going to end up with us having to get something a little more expensive . I was in DSE this afternoon and they have an alarm system that detects motion up to 10 metres - but they couldn't tell me if this was in daylight as well .

If it's for an alarm then it would have to work in both wouldn't it? Not much point having an alarm that only works a few hours a day.

I think the problem is that most alarms are designed to be mounted indoors - not in direct sunlight - so even if they do work during the day the requirement may be that it is in the shade .
Actually I have one of those DSE alarms that I bought a while ago - I'll have to dig it out wherever it is and have a look !

If you can get a microwave motion sensor for a reasonable price, it would be better than IR, they can be tuned for distance/sensitivity & unaffected by light.

Any idea where from ? I just looked them up and emailed a company for a price - maybe I'll know on monday .

They're used as the sensors for automatic door openers and also for alarms where sunlight may strike them.

I managed to get one from Guardall years ago to fire a flash for a similar application, but could try a local alarm / automatic-door installer.

I dug out this old alarm I bought a few years ago - it works at quite a good distance even in direct sunlight .

on the subject of shooting at the right moment (motion sensor trigger aside), here's a photo I found that could be fun to create in a similar fashion. anyhow, good link to an outstanding photographer. each of his photographs hold much for the viewer.
