Traditional home alarm security systems rely on sensors that, as long as someone has remembered to turn them on, can detect windows or doors opening. It is a simple cause and effect relationship: a trigger sets off an alarm to alert neighbours or passersby, or an alarm goes off at the police station or the local security company.



The paid, and often expensive, local security company maybe phones to hear if everything is OK, or maybe even drives by. The police might show up if they're not too busy, but the system is prone to many loopholes. The proclivity of false alarms and the dull routine of the job means that security forces are often slow to respond, and the Police are often too busy. However, that was then, this is now. Wireless home security has changed the way we protect our homes. Let's take a look at some of the benefits a modern domestic security system has to offer.

Wireless: Just One Feature of Many

A wireless home security system is more than simply a traditional alarm system minus the cables. There are two keys to the system:

1. The whole system is digital, so you can program it to function in the way you want.

2. The system is part of your home networks.

What does this mean for your home security? If your house is broken into, the system could ring your mobile phone, or send a text message. You could set it to send messages to more than one cell phone. It could be connected to webcams positioned around the house, all accessed from your cellphone or Blackberry. In short, if it can be programmed, it is possible.

The Central Nervous System to Calm Your Nerves

Once you have a wireless home network with a powerful CPU at its heart, you can pretty well add any kind of detector. Why not cover every eventuality and hook up smoke, carbon monoxide, temperature or motion detectors? If anything abnormal takes place in and around your home, you can get a message via your mobile phone. If your mobile phone can access the Internet, the possibilities are even greater. You could call up your browser and get some live footage from your array of webcams, switch to infra-red if it's dark and maybe listen in too. The security possibilities are obvious, but it also sounds like something that would be great fun to play with... so with motivation that high, your home would be safer than ever.

Suddenly you can monitor all kinds of things going on at home without having to be there. Motion detectors and webcams can let you know whether the dog has curled up on your favourite armchair again. You can monitor the temperature of your greenhouse in winter and your wine cellar in summer. And you can even send a message via the network to regulate the temperature before anything gets spoiled. I'm not sure what you'd do about the dog though. 'Train' it when you get back, I suppose.

The Home of the Panic Button

An often overlooked, but extremely useful feature of a wireless home security package is the addition of a panic button. If you have an elderly or infirm family member, a panic button is a must. If someone sounds the alarm, you can pick up your cellphone and find out what is going on by taking a look, listening in or answering the distress call. Perhaps the sound of your voice coming from the loudspeakers would be enough to sooth your confused aunt with Alzheimer's or your sick child off from school. Perhaps you could even shout at the dog to get out of your lazy-boy.

Finally, the big advantage of building up a wireless home security system is its inherent flexibility. You can add, reposition and take away different components such as motion sensors or webcams without having to rip out lengths of wiring. As the hardware becomes more readily available and commonplace, it is falling in price. Upgrading your entire home would have meant employing a team of professionals just five years ago. Now you can do it all yourself after a brief and relatively inexpensive trip to the mall. Nervous about your home security?
