Locks,
Keys, and Keeping Your Home Safe
The combination keypad-electronic deadbolt is another
alternative to the traditional lock of old. It replaces the deadbolt in
your door to provide keyless entry. To lock the door, simply touch the
lock button on the keypad, and the deadbolt slides into place. To unlock,
enter your combination, and the deadbolt slides into the locked position.
You can change your security code as often as you like, and can program
a secondary list of access numbers for service people who may need entry
to your home. Since this lock runs on batteries, no external wiring is
required, but you'll want to keep your batteries fresh. An alarm can be
added, and will sound after 3 consecutive incorrect codes are entered.
These locks retail for around $200, and will pay for themselves through
increased peace of mind. X10 wiring enables these systems. X10 is a communication language that allows compatible products to communicate via your home's existing electrical wiring, without affecting the regular function of the power lines. Installation of X10 products is easy; you need only install the X10 modular receptacles and program a keypad to control the products you want on the system. The performance of an X10 system depends on the number of devices you have in your house: surveillance cameras, security alarms, door and window locks, security lights, for example, are devices you can place on a house-wide X10-controlled system. Each device is plugged in to an X10 module or switch. Then, using a control pad or your home computer, you can create scenarios for the optimal performance of your X10 system. If you want lights to come on for security purposes, you plug each lamp into a lamp module and change traditional wall switches to X10 switches. Then, using a control pad, or a wireless remote, you program the lights to come on at the desired time and to go off as programmed. This simple application will run about $13 per wall switch and $5 for each lamp module. The controller costs about $8, and can control up to 256 devices, called addresses. Any device that is powered by electricity can be programmed through your X10 system. As long as you have electricity, this technology is available to you! The advantage to X10 technology is that you achieve a
high level of control without re-wiring your house. All it takes is a
remote control that can be programmed to arm the security system, turn
on the lights, lock and unlock the front door, or control the perimeter
cameras that monitor the yard. If you do use a key chain remote, make
sure that you have a spare somewhere, in case you lose the one you use
regularly. And keep the batteries fresh at all times to prevent failure.
