Hello Haley,
We use Art Sentry and its been great. You can set it yourself and monitor it from an iPad, phone, or pc. and it can be either set as a voice or an alarm sound. The cameras are very small. I would suggest talking to them to see what they can do for you. They are the high end solution though, so pricey, but worth it in my opinion. If anything, they will be willing to point you in the right direction to what you need. They are a great resource as well.
Hope that helps!
