OK here's a sort of tricky one, I want to buy a small sports cam suitable for filming my many failed exploits as a cat sailor, thats the easy part as there are loads of sports cams availible. Now the tricky part, to keep " her indoors" on side I also need it for two other applications, both require an external trigger that will be operate the cam for as long as the trigger is operated.

Can anyone recommend a particular cam ?
