Program for Mac that records my computer screen 2+hrs ?

Hi reddit I'm looking for a program that would record my computer screen, for at least an hour or two. My dog is being boarded while I'm on business, there is a webcam I can access to watch him. Yes I know I'm over protective, but I need to make sure he gets his meds..and they've shown themselves to be a little careless with his care today. (no food/water refill before closing, and put in the wrong boarding area) Any ideas on a software for macs? Thank in advance.
