What kind of security does your LO's school have?

We went to her open house last night and I noticed there is no key pad entrance like there was at her last school. The office to the school isn't even directly in front of the main doors, so anyone could just walk in at any time...so it seems. I hope they have some other sort of security in place that I'm just not aware of yet. I would totally help pay for a security guard to work there full time!
