What Is the History of the Burglar Alarm?
Burglar alarms have been around for thousands of years. The most basic alarm used by ancient humans was the dog. It would protect property and guard against people who were attempting to take valuables. Over time, humans used other tricks like chimes to warn them against burglars. Modern burglar alarms, however, are far more elaborate and use advanced forms of technology
Invention:- In 1852, Edwin Holmes invented the first electric alarm system in Boston. The basic design featured a tripwire that electrically powered a solenoid that struck a gong when it was set off. He started a business with the concept and moved to New York
Implementation:
- In 1905, the American Telephone and Telegraph Company purchased the Holmes business. Using the advanced electrical grid that was established in New York, the company linked the personal burglar alarms to police and fire departments
Motion Sensors:
- Starting in the 1970s, a number of alarm systems came equipped with motion sensors. These used basic ultrasonic technology that were emitted from a sensor and reflected back. Any change in sound would cause the system to go off
Improvements:
- During the 1980s, improvements to motion sensors merged with other technologies. Motion sensors began to use infrared technology to avoid false positives and also superior electrical components to establish full home protection systems
Integration:
- Throughout the 1990s, the prices on home security systems fell. Many companies offered free installation packages with a monthly fee. The system was integrated with not only safety services, but also phone support from the company itself
Package Included:
- 1 x Sound and Light Host
- 1 x Wireless Remote Control
- 1 x Wireless Door Sensor
- 1 x Alarm
- 1 x Power Adapter
- 1 x Wireless Infrared

10-28-2009- Other Thoughts: I bought this product just over a month ago. This product works as promised. Very Loud alarm, I particularly like the alert-phone-dialing when security is breached. Exceptionally easy to set-up. Anyone can do it. It takes less than an hour (and I am not much of a handy-man). Programing is very simple, just follow instruction. I did have an issue, however. One item came defective. I called the product manufacturer and the support was less than satisfactory.
