Hardwired vs. Wireless Systems
Depending upon customer preference, home security systems can be hardwired or wireless. If your home already has wiring from a former alarm system, a hardwired system is very easy to add. However, if this is the first time you are installing a security system and no such wiring exists, then adding a wireless system might be the way to go, as there will be no need to drill holes, lift up carpeting, or otherwise disturb your home.
Hardwire systems operate on switching circuits, and don't need
batteries or radio signals. This makes it all but impossible for
even the most technologically advanced criminal to clone the
codes. However, hardwired systems can be tampered with if the
wiring is visible, so it's very important to hide it well.
Most wireless systems are controlled by key fobs, which makes codes unnecessary. They are not connected via wires to a main control panel, and it's easy to include other buildings, such as garages and sheds, within the security zone. Since wireless systems are run on batteries you'll have to monitor each sensor to make sure the batteries are still operating. Many systems have signals that tell the homeowner when the batteries are running low.
Security System Components
A home security system usually requires some or all of the following components:- Control panels. Usually hidden in the back of the garage or closet, this is connected to all the other alarm components. It is the main power source for the entire system.
- Security keypads. Used in hardwired systems, this is located at the front of your home and allows you to punch in your code upon entry.
- Motion detectors. Installed at doors and windows, these detect changes in infrared energy levels or ultrasonic sound wave patterns, and let you know if an intruder is present.
- Door and window contacts. Let you know if a door or window is opened.
- Glass sensors. These go off and trigger the alarm if glass is broken.
- Sirens. These alert the neighbors, and also scare off intruders. These can also include horns, strobe lights, or a combination of attention-drawing sights and sounds.
- Signs and stickers. These can be posted to your home to let an intruder know that the home is equipped with a security system.
