While a clapper may be useful, any short, loud noise will work the same way (including a hand clap).
Also, one caveat about using consumer grade audio with consumer grade video – when I first started out, I recorded a friends wedding – For the ceremony I used a personal voice recorder for audio and a consumer mini-dv camera for video and when I tried to sync, the audio was not an exact match for the video, causing me to have to match up audio to video for every 30 seconds or so – a lot of needless, extra editing. If you’re filming short sequences with a clapper in front of each this shouldn’t be a problem, but if you’re filming 30 minutes at a time, it will be.
