A good video surveillance system should deter criminals, protect you when you're home, alert you to events, and provide rock-solid evidence should something happen. All the while, your security camera system should be easy to install, easy to use and definitely earn you some bragging rights of being able to say, "They picked the wrong place to mess with."
Unfortunately, many people purchase a video surveillance camera system blindly from a consultant, dealer or website and often have regrets.
To make sure that doesn't happen to you, this guide shows how to select the right video surveillance system for your application. It will provide you key points to consider that will uncover your true needs, and help you select the right gear to match your needs and your lifestyle.
Here are some things to consider in making your selection near bulletproof:
Selecting security cameras with the proper lens size is by far the most critical decision for obtaining clear suspect identification. A camera suited with the right lens will yield great results – even when used with modestly performing cameras.
Lens sizes are measured in millimeters. The bigger the number, the more telephoto or zoom capability the security camera will have. To give you an easy to use reference – one of your eyes has about the same field of view as a 3mm surveillance camera lens – or roughly 90 degrees.
So, when you are surveying a camera location, closing one eye will generally tell you what a surveillance camera with a 3mm lens will see. Using a lens with a higher millimeter (focal length) will get you a tighter shot.

Security camera styles
The style of security camera you choose is more important than just a fashionable appearance, although ascetics should definitely be considered. Some camera styles are better for specific mounting locations while others may be more universal.
Another important consideration is protection from the elements – both environmental and criminal. Regardless of the style that meets the needs of your application, nearly all security camera styles offer similar features – so it should not be a limiting factor.
Traditional security cameras
Traditional type surveillance cameras, such as box cameras or fixed cameras are without a doubt the oldest type (hence traditional) and still are the most popular. There are literally thousands of different lenses available for these fixed cameras that make them useful for everything from home/business security to border enforcement and even to covert surveillance operations.
Dome security cameras
Dome security cameras have become much more popular over the past few years and can come equipped with all the bells and whistles, such as a 3-axis internal camera adjustment, a varifocal lens and infrared illumination for night vision. One reason CCTV dome cameras are so popular is that they can be mounted indoors, outdoors, underneath over-hangs, on walls… virtually anywhere.
Like dome cameras, bullet cameras, or lipstick cameras, offer nearly every feature you could want in a camera and more, including longer-range infrared illumination (for see-in-the-dark capabilities at longer distances) and very powerful varifocal lenses. Most lipstick cameras are best mounted vertically on walls or poles.
PTZ security cameras give you the power to remotely control pan, tilt and zoom functions. This allows you to adjust your shot as the action is taking place, and thanks to advanced features offered by most DVRs these days, allows you remotely survey your property from virtually anywhere in the world.
