DV/DVR MD80 Spy Cam with sound detection or a similar camera?

[germany]

I want to observe my bike with a little spy cam which records on a micro SD card via motion or sound detection. Because somebody is pushing my bike from time to time down to the ground. The DVR MD80 has all of that and the battery lasts about 2 hours they say so I guess it's only 1 hour:

The question now is, do you guys know how long the battery lasts in Motion detection mode?

If you guys know another opportunity let me know. It should cost not too much because it's possible that it gets stolen or destroyed very fast.

I baught now the USB spy cam (it's called U8) it has motion detection and has a 200 hours standby time of course I guess that is exaggerated.

Think this would fit your needs?
I only think this item will run for 24 hours, but that's based on a 4GB card. You post a good question and I only mention this product in your thread as I am looking to figure out information such as you and
just thought maybe this product offered any similarities.
