Quite frankly a Raspberry Pi with camera run off a battery is all you need.=
 I would suggest a 6V motorcycle battery float charged off a solar panel if=
 there is no power source available. If you are attending it on a regular b=
asis then such a battery would probably allow the Pi to run 24/7 without a =
float charge and you have some auxiliary battery to charge it from while in=
 attendance. A switching regulator down to 5/3.3V as required would keep th=
e voltage at the Pi stable. This way you have the Pi to do the smarts for m=
otion detection, buffering and storage to SD/USB. The Pi camera is very sma=
ll and could be looking through a miniscule hole. There is a Pi Noir camera=
 which has the IR filter removed for night use if that works for you.
