Do it Yourself Security System Installation
Do it yourself home security systems uses the same principles as a commercial security systems . That is, the layout of the security system is organized according to security zones. The advantage of having security zones , is that if something goes wrong with a particular device, or if an alarm is sounded, you'll be able to trace the source of the problem or malfunction.
Security system control panels have a group of circuits, connectors or terminal strips where wires from each security zone are plugged in. Security system that you buy at a store will have a limit to the number of security zones covered. Some do have add-on capabilities but you'd be well-advised to ensure that your desired system has enough security zones to cover your house and property.
Each security system installation is unique because each house or property is unique and homeowners will want certain rooms or locations protected. That means you will have to plan your layout floor by floor. You'll need to know where each security zone is, how many sensors will occupy those zones, and if you're using a hardwired system you need to know how many feet of wire you'll need to connect all your devices.
Whether you're using a wireless or hardwired system, you need to know where your power outlets are, where the telephone jacks and where the most suitable location is for your main control panel .
If you plan well and are handy with connecting devices properly, you can handle a do it yourself security sys...
Hard Wired Vs. Wireless Home Security Systems
We receive many questions about the merits of wireless vs. hardwired home alarm systems. As you may have read on other areas of this site, we definitely recommend using hard wired alarm components wherever possible. You should also know that some of the "all in one" wireless alarm packages can easily be defeated by even a novice burglar. To understand why, let's first take a look at how a standard hardwired alarm system is set up:
Many people think of the keypad as the "brain" of their alarm system. But it merely sends orders to the circuit board inside your control panel, which is usually installed in your basement (or above a drop ceiling, for example). Ripping the keypad off the wall will not prevent the system from going into alarm, nor will it prevent the alarm from sending its signal. The control panel also stores the back up battery, ensuring your alarm functions during a power failure (average 4-6 hours).
Your alarm's special phone jack can usually be found near the demarcation point of your phone line (where your phone line first physically enters your home). This phone jack enables your alarm to "seize" the phone line to send its signal to the monitoring center. So if a burglar takes the phone off the hook, your alarm will still be able to communicate with the outside world. Another benefit of a regular hardwired system is that you can install your siren in a concealed area, away from the control panel and keypad. This prevents tampering by a would-be burglar.
"All in one" wireless home alarms combine your circuit board, keypad, back up battery and siren all in one "convenient" package. These types of wireless alarm systems have grown in popularity over the last five years or so, but not because they're superior. Many of the "free" alarm companies will only offer this type of unit because they can be installed very quickly and cheaply. Now here's the problem: It's possible that a burglar could completely disable this unit before it has time to send its signal. Now, if this were a regular hardwired keypad, it wouldn't matter. The signal would be sent through the control panel down in your basement or otherwise inaccessible area. But when a burglar disables this unit, it disables everything: your circuit board, wireless receiver, dialer, keypad, back up battery, and even the siren! These "all in one" units can be extremely vulnerable and give you a false sense of security. But What If I Have To Use Wireless, Because Of My Home's Construction?Your home may have a completely finished basement with plaster ceilings. Or, you may live in a much older house that uses plaster walls. In these cases, you have no choice but to go wireless. But you can avoid using an "all in one" unit by simply adding a wireless receiver to a regular alarm system. This receiver would usually be installed, safe and sound, with your control panel to communicate with your wireless devices (motion sensors, door contacts, etc). In addition, some brands of keypads already have wireless receivers built into the unit. Home alarms that use both hardwired and wireless devices are known as "hybrid" systems.
