Entrance alerts may be known by a variety of names like entry alarms, entry chimes, and even exit alerts. Loosely speaking, an entrance alarm is anything that alerts you when someone, or something, enters or exits through a monitored zone. A quick example of one that's been around for hundreds of years is the shop keepers bell that hangs over a shop's entrance door.
