Home Security Surveillance Systems: How Nanny Cameras and Motion Detectors Can Make Your Home a Safe Havenby Jeffrey Parker - home-security-pro.com

Home security surveillance systems have come a long way in the past twenty years and, as the frontline of technology has moved, so the prohibitive price tags on their more sophisticated components have fallen away. Things like nanny cameras have come out of the domain of the rich and famous, and become affordable for ordinary people with day jobs. The same is true of motion detector alarms and door and window alarms.

Indeed, the last of these now cost about as much as a packed lunch. You'll be able to find contacts, the twin magnetic components used to make door and window alarms, for under $4 at most hardware stores. Magnetic alarm contacts form a circuit, which is broken when a door or window is opened, a disruption which in turn signals for your alarm sirens to sound and the police to come a-running. Door and window alarms are so easy to install, you might just as well take the task on as a DIY project - a little silicone and some wood glue and you'll be feeling safer in no time at all. Alternatively, most security companies will provide this most essential part of any home security surveillance system for you relatively cheaply (provided you've agreed to sign a security contract with them, of course).

Installing contacts should be your first priority, as they constitute the first line of your home security surveillance system's defense against that hostile world trying to break into your home. The second line, should someone succeed in breaking in by smashing or cutting the glass of your windows, should be motion detector alarms. These are also fairly inexpensive. There are a few different types, which use different technological principles but wind up having pretty much the same effect. UWB (Ultra-Wideband) radar detectors are one. These emit sonar or radar signals, the same technology used to, you guessed it, detect enemy submarines in times of war. If the signal such a device emits gets bounced back sooner than expect, the device will register that something has moved across its detection field, and activate the alarm siren.

Passive infra-red (PIR) motion detector alarms have become integral to most everyday home security surveillance systems. They measure the infrared light that radiates from objects within their fields of view. When an object of one temperature, such as person, passes before an infrared source with another

temperature, such as a couch, the PIR detector registers that as motion. In this instance, the term 'passive' is used to indicate that PIR detectors do not actually emit a beam of infrared light (you'd need to pay quite a bit more for that), but just passively accepts incoming infrared light.

Out of all these devices, though, the potential of nanny cameras has probably grown the most. You can use them to check your house out at any time of day, by viewing their footage on your computer or cellphone. All you need to do is install them in the relevant parts of your home (which if you're actually a new parent, are those parts of the home where your baby should be), and you'll be able to tell whether the nanny's doing her job.

You can even have the data gathered by your home security surveillance system sent to a remote online storage cluster. Such clusters sell users whatever quantity of space they require at low rental rates. Assuming you're using a looped system of recording (which is really the wisest option, as multiple nanny cameras might record many terabytes worth of footage if left running for too long) you could purchase enough space to store days or weeks of footage for later perusal.

The smart way to circumvent the need for vast quantities of disk space is to have your door and window alarms and your motion detector alarms activate your home security surveillance system. Numerous brands of nanny cameras and home security cameras actually come with motion detection software or hardware pre-installed, so shop around to see what's on the market before you dive in to using software to integrate your door and window alarms with your cameras.
