SECURITY ALARM SYSTEMS AGAINST THE SAVAGE CRIMINALS
In ancient times, the story of the barbarian raids filled halls and homes. The sacking of Rome and the building of the Great Wall of China are some of the many historical notes about the barbarians and the savages which threatened great civilizations of ancient times. Devices were used to stop them, and these include the use of early warning devices to give time for the army to warm up and face the barbarians. In civilized nations, these early warning devices and mechanisms saved many people from the attacks of the savage criminals. Protecting one’s property has been every individual’s business, and he has to do something to stop the potential burglars and murderers. In these modern times, the fear of the savage criminal is still present as we hear news of people brutally murdered in their homes or wives raped wretchedly in the middle of the night. We don’t need to fence our properties with granite walls or high fences, but we can protect our loved ones and properties through installing security alarm systems like CCTVs, early warning devices, and the like.
A Honeywell Vista 20p can serve like a tower in the Great Wall of China. If the Mongolian hordes from the Siberian plains become visible or they are in an attack position, the Han Chinese guarding the tower will burn wood and create smoke. The defenders of the nearby towers will see the smoke and they in turn will burn wood and produce smoke. The process is repeated until the commander or his agents will come to know of a potential invasion. The commanders will then assemble an army to face the invaders or send a contingency to protect the weak points of the wall closest to the invading army. Honeywell Vista 20p functions in a similar manner such that the alarm system will create a sound so loud that it wakes up the inhabitants of the house. In other words, the alarm will give them some time to prepare to confront the burglar or call the neighbors using their mobile phones.
