Installing a security system is all about making your home a less desirable target to potential thieves. For undeterred burglars, it's also important to make sure that ample evidence is available to help law enforcement investigate and convict the culprits responsible. To that end, the cameras you install will be invaluable, so it's important that you choose the right balance of image clarity and concealment, without placing too much emphasis on either one.
The Evolution of Small Cameras
As time has gone on, technology has continuously gotten smaller, and the same is true of cameras. This has allowed manufacturers to produce cameras that are small enough to hide virtually anywhere you'd like to put them. However, the smaller a camera is, the lower the image quality tends to become, so it's a good idea to pay particular attention to the image resolution when selecting smaller cameras.
The primary limitation here is the result of the lens size necessary to capture high quality images. Very small lenses are unable to capture as much light, which reduces the amount of detail in the images they produce. There are some very high resolution pin-hole cameras on the market, similar to those found in smart phones, but any smaller and it's unlikely you'll end up with usable video.
The Advantages of HD Quality Security Cameras
Small cameras make it incredibly easy to camouflage and conceal them, but larger cameras have their place, too. Not only is it easier to find cameras capable of capturing high quality video, but they also tend to be easier to install without having to purchase a separate power source. Further, a camera which is large and visible can be a deterrent all on its own, making it obvious to burglars that they'll be caught on film.
When using cameras that are hard to conceal, it's important that you position them in such a way that they are difficult to reach from the ground and far from any entry points. This will help ensure that they have the best possible chance of capturing an intruder in the act, and will reduce the likelihood that they'll be disabled during a break-in. Properly installed, a good camera with a wide-angle lens should cover as much of the room as possible, limiting the chances that a thief will be able to pass it unseen.
When it comes to security cameras, bigger isn't necessarily better, but that doesn't mean standard sized cameras don't have their place. Remember, there's a balance to be found between these two extremes. Make it easier on yourself though, and work with an experienced security consultant, like those at Home Theatre Designs, to make sure you choose the best product for your home and your budget.
