Remote access intercom systems?

[Haley M.]

Hi everyone - we're looking to update our intercom system in our 4-unit building in Boston. I'm interested in a remote-access system so that people can buzz in deliveries even if they're not home since we don't have a doorman (and packages get stolen all the time here if left on the steps). Does anyone have these types of systems, and if so, which ones should I be looking into? I had received a quote about a Comelit system but I can't find any information about them. Thanks!
