Perimeter Protection Parameters
For guarding the perimeter of your home, there are several basic home security systems.
One simple home security burglar alarm has a small button, which is used as the switch mechanism. The professionals or do it yourselfers that install the home security system embed this button into the door frame and then when the door closes the button embeds itself into the door frame so that the act of closing the door actually pushed the button in. If, however, somebody opens that door the home security button would be released. This would change the circuit on the burglar alarm and the alarm would sound.
These home security systems are, however, so basic as to be seriously flawed. The reason is that if the burglar closes the door the alarm shuts off. In order to improve the home security systems, the newest burglar alarm systems have upgraded these button systems to include a home security system control box into the circuitry.
The control box of these home security systems are joined to an alarm circuit, and sometimes more than one circuit, but they also are powered by a separate power source. This power supply monitors the home security system circuit and sets off the alarm when the circuit is broken, either by the entryway being opened or closed depending on which type of home security system is being used. The added safety feature installed with this circuit box, however, is that a security code must be entered into the home security systems keypad before the alarm will deactivate once it is set off. These home security systems’ installers are clever about where they install the keypad too, placing them in places where a burglar is not likely to locate them.
There are so many ways to use the control box home security systems. You can choose windows or doors as entryways. For a window the home security system’s current would run through a foil wire attached to your window glass. If a burglar were to break that glass, she or he would be breaking the circuit and thus setting off the alarm.
You can even incorporate your rug or floor mat into the circuitry of these highly adaptable home security systems. Your simplest floor mat, for example, would have a home security circuit installed as two widely spaced metal strips. An intruder stepping on the mat would create enough weight and pressure to bring the metal strips in contact with each other. This circuit completion would set off the alarm of this home security system.
While these open circuit and closed circuit entryway home security systems are good burglar deterrents and detectors for keeping your home free of intruders, they are only adequate for protecting the perimeter of your home. That is because there are just so many entry points from the outside of your home and it’s clear what these are - your doors and windows. It’s easy enough, therefore, to focus your home security systems on the various doors and windows when protecting the home’s perimeter.
When it comes to protecting your home’s interior, however, a burglar’s options become far too numerous for these home security systems. This is when motion detectors are the ideal home security systems.
