Home Security Surveillance Systems - Nanny Cams and Motion Detectors Can Make Your Home a Safe Haven

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.

Window and door contacts: cheap and easy to install

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).

Motion detector alarms: inexpensive and highly effective

Since contacts guard your doors and windows, you should consider them the first line of defense for your home security system. Next on the list should be motion detector alarms. These, too, are relatively cheap. There are a few different technologies that allow for motion detection. Ultra wideband radar (BWR) detectors emit an inaudible signal over a fixed range. If that signal bounces back sooner than expected, the BWR detector knows that something has moved across its view, and trips the alarm.

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.

Nanny cameras: peace of mind wherever you are

Nanny cameras have probably evolved the most out of all home security surveillance systems - their footage can be viewed online over your cellphone, allowing you peace of mind even when you're over continent away. In fact, this is an effect you can have with your entire home security surveillance system. Simply install decent webcams covering relevant parts of the house, and you'll be able to see not only your baby but also whatever the nanny might be doing with the house while you're gone.

The data from your nanny cameras can be streamed to an online storage cluster, and stored for days, weeks or months (depending on how much you're willing to pay for the privilege), allowing you to review incidents long after they transpire. Of course, online storage is only cheap up to a point - a serious home security surveillance system might call for many terabytes of storage space, assuming that you're recording every minute of every day from multiple cameras.

There is a way to get around this, of course. It's as simple as using your motion detector alarms, along with your door and window alarms, to activate your webcams, so that they're only switched on when there's actually something going on in the house. There is a variety of software designed to integrate home security surveillance systems that allows for this, and numerous brands of security camera come equipped with motion detection right out the box.
