With only 2Mega Pixels the quality of the recording will be affected by the speed of movement. When using it whilst mountain biking, it can be jerky but when walking the quality is good. Remember that it is a £30 camera, not a Hero. Certainly worth a try.
All comes down to lighting available as well. Its not expensive so worth a try also note that battery on my camera lasts at most 2 hours before needing charged up again hopefully that would be long enough for you. As the other reviewer states all depends how quickly you are moving as well which I would imagine would be quite slow.
