Home-Securtiy 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. Even if you’re only about as good with a computer as the average 11-year-old, odds are you’ll be able to set up your own, personal wireless security camera system. Simple motion detection software can be downloaded off the internet (check out http://bit.ly/T8KF6), ensuring that your cameras only record when there’s actually something going on in front of them. Concealing a wireless security camera in a desktop ornament, like a paperweight, teddy bear or clock, is as simple as removing the intended housing’s components and drilling a couple of holes (one for the lens of the camera, and another for the feeder cable to power the device). Wireless webcams, it seems, are getting smaller with every passing day, even as the quality of the footage they’re capable of producing increases to dramatic, even superhuman levels. 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 technologies have been in use for quite some time. Indeed, one of them is indubitably responsible for flicking the light in your driveway on when someone walks across it. As a side note, the sensors have also been very well-refined in order to prevent false alarms, such as those resulting from a cat or small dog walking past a sensor. ‘Pet-immune’ home security systems utilize PIR detectors fitted with a mirror or lens modified so as to stretch the heat blip created by moving objects. Through some clever manipulation, these mirrors magnify the blip produced by a human, and reduce those of a do or a cat. If you have the money lying around, it’s also possible to find wireless security cameras equipped with the software to discriminate between animals and humans in a similar fashion. Remember, throughout all of this, that the location of your wireless security cameras and home security sensors is probably the most important consideration when it comes to setting up a modern home security system, especially if you’re trying to keep prices down. Windows, doors and skylights should be first on your list of things to cover, as these are the only points by means of which a criminal can reasonably access your home. If you can only cover a limited number of your access points, rather choose to focus on the more obscure, the doors and windows away from the street, where exposure to public view would, normally, prove too much of a risk for would-be intruders. The other, most crucial question in this business is – who exactly is going to monitor your home security system? It’s no good having an alarm system if there’s no one around that’s paid to respond to it, and respond quickly, with due diligence and a bit of fire power. If you aren’t signed up with a security company, the best your system could do is scare intruders away with a loud siren, or perhaps even call the police with a looped recording requesting their assistance. Neither of these methods is as foolproof or reassuring as actually having a security company, like Chubb or ADT, at your beck and call. Security companies will often install any of the aforementioned home security system components – home security sensors, motion detectors, wireless security cameras – at low rates for new customers that sign security contracts with them.
