Despite the name, most home wireless security systems do require a few wires. These connect the main panel to power, a wired keypad, and a telephone line. Usually, a little planning will allow the unit to be located a short distance from these things. The few wires needed can be fished vertically through the wall, or stapled to trim or baseboards.
Here are some things to consider when deciding where to place each piece of equipment. Whether you’re thinking about a DIY home alarm system or shopping home alarm companies, this will help you get the best wireless home security system.
Home wireless alarm system panels are often placed in the laundry room, near the entry/exit door to the garage. Power can often be found along one of the interior walls, and a phone jack is sometimes wired in the garage. If there is attic access, a phone line can easily be run. This could go to the nearest jack, or directly to the service drop on the outside wall of the garage.
Non-monitored home wireless security systems don’t really need a telephone connection, unless you’re getting a system that allows remote access features. It’s still a good idea, since then you can easily have the system monitored in the future.
Power is supplied by a small plug-in transformer. This runs the panel, and charges its back-up battery. The outlet used must be un-switched, which is usually the case in laundry areas. If the transformer were plugged into a switched outlet, and someone turned off the switch, the alarm would drain its battery in a few hours.
Systems like the Ademco Lynx combine the keypad, dialer, receiver, and other major components in a single unit. These types of systems still need a nearby 110-volt receptacle, to plug in the transformer. They also need a telephone connection for monitoring to work.
This minimal wiring makes installation simpler than larger systems, and is a perfect fit for a smaller house or apartment.

Unlike the "all-in-one" types, other home wireless security systems use a keypad separate from the main panel. The keypad is needed for programming, and some alarm systems combine it with a built-in receiver. Locating the keypad directly below the panel, next to the garage door, is the easiest, since a short wire can be fished down the wall to connect the two.
The keypad can be placed inside or outside the door, your choice. Opinions differ on which of the two is “better”, even among alarm professionals. I’ll tell you the arguments for each, and you can decide!
Arming Option: A keypad inside the house can be used to arm and disarm the system,
without opening the door. This is good if you only have one keypad and
you intend to arm the system at while you’re home.
Audible Alerts: Inside keypads can be heard through the rest of the house much
easier than outside units. This is mainly helpful only if you plan on
having the “chime” feature on when you’re at home.
Tamper Prevention: Many people want the keypad inside to prevent tampering and
disabling the alarm. While modern systems can’t be disarmed without
entering a valid code, a keypad/receiver combination unit could be
damaged so as not to receive alarm signals from transmitters.
Security: Another worry with an outside keypad is that someone can see if the alarm is armed or not.
Both of the last two issues are more of a concern if you have an open carport, rather than an enclosed garage. Garages are fairly secure, considering how much easier it is to break into a window.
Early Warning: An outside keypad can alert you to an alarm condition before you even get out of your car. You can then back out of the garage, go to a neighbor’s house, call your alarm company, etc. This is probably the biggest single advantage of having a keypad in the garage, and many people base their decision on this.
Arming Option: Another minor plus to the outside location is extra arming options. When leaving the home, most systems allow you to arm the system without the usual delay on the garage door. This means the alarm will sound instantly on opening the door, leaving an intruder no time to try to defeat the system. It’s true that this is more secure than having a delay, but many people never use the feature anyway.
The Bottom Line:
Think about how you and your family will use the alarm system, along with the points above, and pick the keypad location you’re most comfortable with.
There is another benefit of placing wireless burglar alarm systems next to the garage interior door: This allows the door to be hardwired. Many wireless panels also have a zone or two available on the circuit board for hardwired points. How does this help us?
Being the main entry/exit door in most single-family homes, the garage door gets the most use of any opening in the house. If a wireless transmitter is used to secure it, it will transmit every time the door is opened or closed. (Many units are designed to send several rounds of signals for each opening or closing). This will wear its battery out much faster than the other transmitters in the system.
By hardwiring this door, there is no transmitter needed, and no battery to change. As a bonus, you’ll save a little money, since hardwired contacts are cheaper than wireless transmitters.
Even though home wireless security systems aren't totally wireless, plan ahead of time for the few wires that are required will make your whole installation go easier.
