Burglar Alarm

Ancient Japanese temples and castles had thief proof "Nightingale" floors that chirped when walked on.

Before electronic alarms, the first man-made intruder warning system was created in England in the 1700s by an inventor named Tildsley. It used a simple set of chimes mechanically linked to the door lock. This rudimentary system would make noise if someone tried to use the wrong key, alerting the homeowner and potentially scaring off intruders.

Augustus Pope was awarded a patent for the “development of an electromagnetic alarm” in 1853. He then sold his patent for US$1500 to Edwin Holmes, a manufacturer of ladies’ hoop skirts in Boston Massachusetts who was a far better publicist. Holmes installed the first burglar alarm on February 21, 1858.


By 1877, Holmes had established the first network of alarms monitored by a central station in NewYork and sent his son, Edwin Thomas Holmes, to copy this system in Boston.

Edwin Thomas Holmes' workshop was used by Alexander Graham Bell as the young Bell pursued his invention of the telephone. Thomas Holmes was the first person to have a home telephone.

The late Nirvana singer Kurt Cobain's body was found in his Seattle home by an electrician sent to install a burglar alarm. He was believed to have died of a self-inflicted gunshot wound three days earlier.

Approximately 40% of United Kingdom households have a burglar alarm installed, but surprisingly, 34% of those rarely set it.


It's estimated that 9 out of 10 burglars would choose to target a home without a burglar alarm over those with one.

A burglar occurs approximately every 18 seconds in the United States, equating to almost 200 per hour or 4,800 every day.

Only 1 per cent of car alarms go off because of an attempted theft.
