Best wireless camera to play table tennis?

[scrubplayer]

I happen to come across this video:

1. can anyone name that camera?
2. will that camera affect play?
3. Are there small wireless camera out there that can attach to shirt that doesn't drop and doesn't affect play? It would be awesome to have it and record it.

He's probably just using a GoPro with a forehead mount.
