Nanny Cameras And Motion Detector Alarms: Maintaining Peace Of Mind With A Home Security...

The last twenty years has seen the complete democratization of communication and information technologies. Gizmos with functions formerly reserved for companies with hundreds of millions in their pockets can now be found on the desks of ordinary working people. High quality nanny cameras, which capture digital footage as perfect as any camcorder, are one of the technologies to make their way out of the homes of the wealthy and award-winning and into the lounges of the world. This is also the case with door and window alarms, and with the ubiquitous motion detector alarms.



Indeed, to say that window alarms now cost about as much as a few burgers from McDonalds is really no exaggeration. You can purchase contact pads, the simple magnetic components for door and window alarms, at large hardware and department stores, often at bargain-bin prices of under five dollars. These magnetic pads form a circuit which, when broken, signals the central alarm hub and gets that siren sounding. Even for someone with little experience in terms of working with hardware, taking on the task of installing contacts as part of their home security surveillance system will probably not pose much of a hurdle. You scarcely need more than the cabling, the contacts, some wood glue and a silicone gun. This is a service you can also have done for you by the majority of security companies, though you won't get their best prices unless you've signed up to use them to monitor your alarm system.



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.



Out of all home security surveillance system components, nanny cameras are probably the devices that have evolved the most. From the fuzzy, pixilated footage of yesteryear, these devices are now more sensitive than most human eyes and can be easily rigged to stream their footage to your very own secure website, allowing you to check on your baby even if you happen to be a continent away with nothing but a cellphone.



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.
