Home Security Systems
Over the past several years, the face of home protection and intruder detection has changed dramatically.
Among the new and improving technologies included on the 'hot list' are the wireless home security systems.
It used to be
that the most effective security solution required installing a hardwired alarm
system. Despite the labor-intensive need to run wires throughout a building, these
traditional alarm systems were reliable, and for the most part, relatively inexpensive.
Then wireless technology came along,
giving us an alternative. But despite the convenience, early wireless home security
systems were less reliable, and usually more expensive. This turned people away
and back to the traditional hard-wired alarms.
Wireless Home Security Catches Up
Over the last couple years, wire-free security equipment has become mainstream, with much better technology, greater reliability and lower cost. So for good reason, wireless home security systems are the fastest growing section of the security market. Now anyone with can install a professional quality alarm system without running wire through all of the walls, significantly reducing the installation time, and ultimately reducing the overall price.
Due to the technology, wireless equipment can sometimes cost more. But they make up for it in savings on installation labor. To reduce the cost further, some people install an inexpensive wired control panel, run cables to the part of the home they can reach, and then add wireless to the rest. With the numerous accessories available, it is easy to extend your system outdoors.
If
your property isn't already pre-wired, a wire-free alarm system should probably
be your first consideration.
How It Works
Wireless home security systems use sensors, cameras, and other peripherals that run on radio wave frequencies. Self-illuminated keypads at your front and back doors allow you to deactivate your alarm with pass-codes you select.
These devices communicate with the control panel, the brains of the system. If the alarm is set off, a monitoring station confirms if it was intentional and sends authorities to the scene. And if your power goes out, a backup system kicks in to make sure you maintain 24/7 protection.
Wireless
sensors and cameras are designed to transmit a unique identification code to a
controller. The controller learns the identity of each device and links it to
an appropriate zone. Each sensor also transmits status information such as battery
voltage, condition of the sensor switch, and other diagnostic messages.
Wireless Monitoring and Notification
Taking advantage of the cellular technology that seems to be everywhere, one of the newest wireless features uses the cellular telephone network to monitor your alarm system and to signal for help if an intrusion or other problem is detected.
For example, a motion detector or alarm might trigger a call to your cell phone in order to inform you of some unexpected activity. You might then log on to the internet and get pictures from your security camera of what's going on at your home.
If the power is out (and therefore your internet connection is down), or if an intruder has cut the phone lines, alarm signals can be immediately transmitted through a cellular connection from your home security system to a central monitoring company for emergency notification and dispatch.
The advantages of wireless
home security systems are significant, and there are a whole range of sizes and
price ranges to fit almost any need.
