Home Security Surveillance Systems: How Nanny Cameras and Motion Detectors Can Make Your Home a Safe Haven

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, 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).

After contacts, which form the first line of defense after locks when it comes to home security, you’ll want to think about beefing up your home security surveillance system with motion detector alarms, which are generally of one of two types, and also tend to be generally cheap (think under 20 dollars). UWB detectors (the acronym stands for ultra-wideband radar) emit a radar signal across a fixed distance. If that signal echoes in a shorter than anticipated time the UWB detector will register the presence of a new object as motion, and sound 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 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.

There is, of course, no reason you shouldn’t have your entire home security surveillance system function in this manner. All you need to do is buy up a bunch of webcams and convert them into nanny cameras by putting them in common household objects and ornaments such as clocks and book-bindings. The only requirement is that your ornaments be located within reasonable proximity of a power point. The footage these makeshift nanny cameras capture can be transmitted directly to a storage cluster online, where it will remain, safe and secure, for days or weeks – the only dependency being how much you’re willing to pay for the storage space. Keep in mind that an extensive home security surveillance system might require multiple terabytes of space for just a few days worth of surveillance.

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.
