Development of burglar alarms
Audible only intruder alarms (the ones which make a racket and annoy you and your neighbours), simply do just that, and very little else in the way of security.
Burglar alarms are so common around the world that it’s difficult to imagine a time when there wasn’t such a thing as an “alarm” in the form of some device that either buzzes, bleats, screeches, clangs, or makes some kind of noise to provide us with a warning that someone has broken into our home.
Ever wondered where the idea for a burglar alarm came from? The history of the burglar alarm is interesting because the need for people to protect their property and themselves goes back thousands of years.
Before any sort of modern alarm was invented, livestock or guard dogs were known to have alerted homeowners of unwelcome guests. Many policemen today will still recommend a dog as the best form of home protection.
As early as 386 B.C. the Romans used geese to warn them of danger. They believed that intruders could easily sneak past guard dogs or subdue them quickly, rendering them useless. They believed that the sound the geese would make upon being interrupted would definitely wake them up and allow them to intercept any trouble. ‘The intruders slipped past guards and dogs, all asleep, but the cackling of the birds and the clapping of wings awoke Marcus Manilius.’
The history of home security systems dates back to the early 1700s, when the English inventor Tildesley created the first home intrusion “door alarm”. Tildesley worked out that by attaching chimes mechanically to his door lock, the chimes would sound when the intruder used a skeleton key or similar device to open the door. Even though his design was quite simple, just a set of wind chimes linked to the door handle, it proved an extremely effective tool in deterring home invaders. Tildesley claimed, “It would doubtless prompt him to take precipitate flight.”
The latter half of 1700s also saw the creation and implementation of some of the first door locks, as the lever tumbler lock came onto the market in 1778.
It’s hard to believe but the first electro-magnetic alarm system in the world was patented on 21 June 1853 in the name of an American gentleman called Augustus Russell Pope. His device used magnets, electricity and alarm bells installed above door frames.
