In addition to the panic stations, there is an app that UNCC uses, as well as many other Universities, called LiveSafe on Google Play. Pretty sure there is an iOS equivalent but I can't seem to find it. Anyway, this app provides an option to press one button to call for help either via 911 or to Campus Police. Calling for help will send your GPS location to the police as soon as you press the button.
This app will also allow you to send anonymous tips to Campus Police if you see something happening that you think shouldn't be but don't want to give away your identity.
