Use a 4060 timer IC to get that 20 minute duration which cannot
be reliably done using a 555 on either side of the Atlantic ocean
UK or Florida.

I found a YouTube video that explains how to make a "motion detector spy [video] camera" system. The video is about 10 minutes long (so I didn't watch the whole thing), but those that commented seem to be very happy with the tutorial. I imagine you can adjust the recording time as well. I know its not the "laser" system you asked about, but perhaps this will work for you?

You can get something working with a Spy Gear laser trip wire kit and a programmable timer. Or you can use a Passive Infrared light switch to power up your video camera when it sees the heat from a body or animal.
