"It's quite easy once you know how, one simple Freezing Charm on these absurd burglar alarms they use instead of Sneakoscopes and make sure the neighbours don't spot you bringing in the piano."
Horace Slughorn on breaking into homes[src]

A burglar alarm is a Muggle electronic device used to detect home intruders. Wizards can easily disable a burglar alarm by a casting a Freezing Charm upon it, as demonstrated by Horace Slughorn, when he disabled the alarm of a house in Budleigh Babberton in the summer of 1996.[1]
