You need a source of infrared light to see anything so I used a remote control I had lying around. Here is some video of me waving at the camera.
And shining the remote control at the camera.
To record the video I used the raspivid command with the night exposure option.
raspivid -t 20000 -rot 180 -ex night -o hand.h264
The omxplayer command is handy to playback the results.
