[Five Nights at Freddy's]Why doesn't the security guard not just protect the restaurant by standing guard outside?

Mainly talking about the first game. Like from my knowledge I don't recall any of the phone calls talking about why they need to actually even be inside the restaurant. Like maybe the first night they might not know the animatronics try to kill them, but after the second night, I wouldn't want to spend time inside with them risking my life for a meager 24 dollars a night. 

So why doesn't security person just go outside at start of the shift, deadlock the doors with chains and stuff, and just watch the restaurant from there. If someone really wanted to rob it or something, they'd have an easier job of stopping them. Also, not having to deal with murderous robots.

I used to work security, and the answer is... post orders. The guard has probably been given orders on what exactly he is and isn't allowed to do. And going against said orders is grounds for termination.

Now of course there's some suspension of disbelief here as the very first night a guard would see these dangerous animatronics coming for him he'd be well within his rights to do whatever the hell he wanted, inform local law enforcement, bring in a gun against post orders, take his getting fired up legally if it went there, etc.
