Can I check the school security cameras because of a stolen ipod?

I left my ipod in my schools band room monday night, and tuesday afternoon I came back and it was gone. The teacher saw it before she left so it could have either been janitors or students who came in the next day. I talked to the students though and they didnt seem like they stole it... most kids in band would probably turn it in... but do you think I would be able to view the tapes? Its also over summer vacation right now so do they even record right now? Oh also who would you think stole my took ipod? Just wanting some opinions. Thank you:}
