<human>: I live with my parents and my 2 younger siblings, both each invite their friends over a lot. I trust my brother, who sometimes server himself from my own mini-fridge but end up telling me whenever he does. My sister, on the other hand, has quite the history of doing as she pleases and taking whatever she wants. I don't trust any of their many friends either (they are pretty shady).

The mini-fridge used to be for everyone, but i ended up being the only one using it, so i was authorized to move it to my room, hoping i could keep a closer eye on it. To no avail. 

This month, half the beer i bought were stolen. No attempts were made to cover it up except moving them up so it looks like nothing was touched. That may work for a can or 2 once in a while, but not for 8 cans of beer OVERNIGHT. 

That's simply insulting. Which is why i want to catch whoever is stealing my drinks and be able to prove it without the shadow of a doubt. I am fairly certain it's my younger sister.

I attempted to record, using xsplit and a webcam, last night. Before i left, i counted all my cans of coke and beer and placed them neatly. I am sure i am not being paranoid here. So when i noticed i was missing a whooping 8, i was excited to know i had it all recorded and could finally expose her as she is, without the possibility of her denying it.

Unfortunately, the video is only 8 hours and 33 minutes of the nearly 24 hours i was gone... and it freezes 1 minutes and 33 seconds in.

So reddit, what would you suggest me to catch her, or whoever is stealing my drinks, red-handed. I am moving soon so buying a lock would not achieve much anymore, and quite frankly, would be so unsatisfying. What recording program, or clever ideas, would you suggest me?

Can you give me the gist of the text in a nutshell?
<bot>: My sister is a spoiled cunt and she or her friends are blatantly stealing from my mini-fridge on whatever occasion they get. How can i catch and prove whoever is stealing from me.
