Your Home Under Surveillance

DIY Home Security Systems – Putting Your Home Under Surveillance With a Home Security Camera System.

Suggest the possibility of DIY home security systems a decade ago, and most people would probably have thought of Kevin McAllister’s booby-trapped course of swinging paint-tins and electrified doorknobs in Home Alone. Indeed, visual, auto-detection and information technology was, at the time, something only lettered professionals could really muck around with (and was, even then, notoriously glitchy and unreliable).

But right now, we’re in an age where hardware crashes are rarer things. Computers are tougher, and are used as control hubs for countless robotic technologies, of which detection, recording and media-storage are some of the least logistically challenging. Setting up a DIY home security system is really not something to be intimidated by – home security camera systems can be constructed from the simple webcams people use to chat online, and, for a little more money, infrared security cameras can conquer issues of lighting and motion detection in the gloomier parts of your home.

Don’t get ahead of yourself

If the prospect of constructing a DIY home security system appeals to you, the best place to start is with the lowest of tech. An estimated 60% of burglaries in North America occur due to a door or window being left open. Make sure that you and your family are in the habit of locking everything up, even if you’re just nipping down to the 7-11 for a pack of cigarettes.

On from this, you’ll want to install contact sensors on all your windows and doors. Contact sensors are simply two pads which, when in contact, complete an electrical circuit. If that circuit is broken by, say, the opening of the window, a switch will trip in the contacts, causing them to signal to their central hub (which, in the case of a DIY home security system, would probably be your personal computer). Contacts can be purchased for less than ten dollars at most hardware stores.

Video surveillance on a budget

If you’ve decided to rig up a full-fledged home security camera system as part of your DIY effort, you could arrange your contacts in such a way that they’ll activate your security cameras, setting them to record as soon as the circuit is broken. For DIY home security systems, there’s no reason to get anything more sophisticated than a webcam to act as your security camera. These can be had for under $20, and are widely available in department stores and through computer supply chains.

For those with more cash in hand

The purchase of an infrared security camera, on the other hand will almost indubitably leave your wallet substantially lighter. Their benefit over night-vision cameras lies in their ability to present detailed, high-quality images regardless of lighting conditions. Infrared cameras do this by recording the black body radiation of objects, something living creatures display a lot more of than inanimate objects do. The inclusion of infrared security cameras will not only eliminate your need for smoke sensors (as they double as fire detectors) but will bring your home security camera system firmly into the 21st century, as it renders it immune from changes in lighting and atmospheric conditions.
