Home Security Surveillance Systems: How Nanny Cameras And Motion Detectors Can Make Your Home A...

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.



Magnetic alarm contacts, the twin magnetic pads used to make door alarms, cost less than $4, and are available at the majority of major hardware stores. These contacts are used to form a circuit that's broken when a door or window is opened. They're so easy to install that many people these days are undertaking the job of incorporating them into their home security surveillance system themselves. Of course, if mucking about with silicone guns and tubes of wood glue isn't your bag, security companies such as ADT are usually willing to do the job at minimal cost for their customers (though this will, of course, only apply if you're signed up for their security services).



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.



PIR motion detector alarms are the more common variety in modern home security surveillance systems. The acronym stands for 'passive infrared', as these devices passively sit and 'stare' over a fixed distance, registering the heat of the various objects in that area. If the temperature of that area changes in just one place (rather than ambiently), the motion detector will register that as motion. These are the kinds of devices you'll typically find over peoples' front doors or driveways, used to switch on a porch or outdoor light when they sense any disturbance.



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 a 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.



Still, this is only cost-effective up to a point. Luckily, there's a simple way to get around the need for making excessively large quantities of storage space one of the costs of your home security surveillance system. All that you need to do is have you motion detector alarms and door and window alarms wired to your nanny cameras. If you set this system up in such a way that the various sensors or detectors set your home security surveillance system recording when there's movement in the house, you'll wind up eliminating the need for redundant recordings of empty rooms. You can also get cameras programmed with motion detection software to begin with - these will actuate this function without the need for any fancy fiddling on your part.
