Becoming A Home Security System Expert: How To Use Wireless Security Cameras And Home Security Sensors

By Jeffrey Parker

Getting a home security system is not something to put off for the future, to jot down on that list along with getting fit and picking out a great outfit for your cousin’s wedding. It’s something that should qualify as a top-level priority for anyone seriously concerned about their own well-being, that of their family and that of their personal possessions. These days, installing a home security system is far from being the colossal hassle it was in previous years, when the technology was still fresh and adequate knowledge confined to those with an understanding of sophisticated electronics and complicated, arcane computer user interfaces. Wireless security cameras and home security sensors, of both the infrared and contact variety, are sufficiently easy to install that you can learn all you need to know in an hour of web-surfing. What’s more, they’re cheap enough to make the cost-risk equation a real no-brainer.

Creating a Hollywood-style spy camera inside a teddy bear, a toy, or a paperweight is one carnival trick that’s become very easy to perform. You can set these covert wireless security cameras up as an integral part of your home security system, even if you know no more about computers than your typical 7-year-old kid. Just drill a hole in the underside of the device you’re using to conceal the camera, cut a lens hole, drill another hole in the surface on which you plan to keep the ornament (for the power cable) and voila, you’re all set. If the feed cable is a USB, then the camera doesn’t even need to be wireless – you can power the device and retrieve information simultaneously. Note that you can save a lot of money on storage space by using basic motion detection software, which will activate the recording function on your cameras, thus eliminating the need for constant recording.

There’s no reason why you shouldn’t have your wireless security cameras activated by motion detection devices, home security sensors that require none of the disk space called for when recording footage. UWB (ultra-wideband) radar sensors are one such form of home security sensor. They function by bouncing a signal over a fixed range. If the signal returns more quickly than usual, the sensor reads this as indicating motion, and sends your home security system into high alert. Passive infra-red (PIR) sensors operate by a similar principle, only by sensing infra-red radiation instead, activating when an object of sufficient heat move across their visual fields.

These are the same kinds of motion sensors that activate your porch light when someone walks across the driveway. The technology has been around for a long time, and has just about been perfected, to the point that upper-range home-security systems incorporate sensors with pet-human discrimination technology. PIR detectors can be made to discriminate between pets and humans by use of a modified lens or mirror that vertically stretches the zones in regions closer to the sensor, an effect that reduces the size of the ‘blip’ created by, say, a cat, and increases that created by a person. The industry term for such discriminator home security systems is ‘pet immune’. Wireless security cameras can be programmed with software for a similar effect.

If you plan to install a home security system incorporating wireless security cameras and home security sensors all by yourself, there are a few important considerations you’ll want to keep in mind. One is location. Ideally, cameras and sensors should cover those areas through which an intruder will have to pass in order to access the house. So doors, windows and skylights should be first. Be more concerned about those entry points that are off the street and shielded from public eyes, as they’re the ones morel likely to be used by intruders.

Now, perhaps the most important factor in rendering a home security system effective is good monitoring. Most home security companies, along the lines of Chubb and ADT, will be willing to install your wireless security cameras and home security sensors for you, and provide you with a fully integrated, professionally tweaked home security system from the word go – provided, of course, that you plan to sign a home security contract with them. Despite the fee every month, such backup will really provide the ultimate in peace of mind short of having your own bodyguard. If you’d prefer to be independent in terms of the monitoring of your system, then be sure to install a loud siren to activate if your perimeter is breached, and, to further discourage intruders, a sign proclaiming your membership with ADT or some other security company. You might even want to rig your system so that your computer calls the police with a looped, pre-recorded message requesting their assistance (though there is, of course, no way of knowing how the police will respond to such a call).
