How Home Alarm Systems Keep Your Home Safe

old lockIn olden days, home alarm systems were made up of locks, bolts, guard dogs, and a shotgun over the mantle. Homes were more spread out, and families, for the most part, had to fend for themselves, relying upon the man of the house as a protector and guardian. If danger came knocking, help was hard to reach, and most homes were left to their own devices for defense.

In today’s busy world, many things have changed. More and more people spend less and less time at home because of busy work schedules, and suburban areas force burglars to be cleverer and make home fire hazards a hazard for the whole neighborhood. Help may arrive faster, but that’s only assuming you are at home and aware of the emergency or are able to get to a working phone in time. Let’s face the facts: these modern perils require modern defenses.

Those Modern Defenses

With advances in circuitry, the possibilities are endless. Take a typical door alarm, for instance. All it takes is a simple circuit to alert you to a breach of your home. The kinds that work the best are closed circuit, meaning, when the door is shut, the circuit is closed and electricity is able to flow easily through it. This is usually done by placing the circuit switch on or in the doorframe and a magnet on the inside edge of the door. The magnet keeps the switch closed, so when the door is opened, the switch is released, breaking the circuit and sounding the alarm. This same simple circuit concept applies to window alarms and pressure mats. If a window is opened or broken, the circuit opens and sounds the alarm. In pressure mats, the circuit is originally open, and then it is closed when stepped on, thus sounding the alarm. Most professional home security systems have wiring throughout the house that is connected to a control box separate from these devices, which triggers the alarm and can only be stopped by a correct pass code.

Motion sensors are also incredibly interesting. Rather than using simple circuitry like typical door alarms, many motion sensors are photoelectric. On one side of a room is a light or laser, and on the opposite wall is a photo detector, which detects the light emitting across from it. If the light is interrupted, say, by an intruder, the photo detector will notice the absence of light and immediately sound the alarm. Some smoke detectors even work this way, with a photo detector and light beam placed 90 degrees from each other. When smoke enters the space, some of the smoke particles cause the light to bounce off of them in the direction of the photo detector, which triggers the alarm upon detection.

With the touch of a button, they can call your home and gauge the situation. With no response or an incorrect response, they immediately alert the police or fire department, resulting in a much faster response time, whatever the emergency. This kind of backup and response takes much of the burden of the protection of your home off of your shoulders. It provides for faster response times and goes a long way toward stopping and preventing crime and disaster. In fact, 9 out of 10 burglars avoid houses with wired security systems because it simply isn’t worth the risk and effort. The more homes opt for these systems, the fewer criminals are willing to take a chance at breaking and entering.
