CCTV systems are a valuable addition to any home security system. Choosing the right system for your home, however, can be tricky if, like most people, you don’t know much about the technology. It doesn’t have to be complicated, though. Just keep in mind the basics of CCTV systems and figure out which kind of security camera and monitor system is right for your home or business. This basic overview of CCTV systems will help you choose the right pieces to put together a great system.
Appearance
Let’s start with the least important but most obvious factor first – looks. The CCTV camera with many systems is quite obvious and easy to see. If you’re buying a security system for your store or business, this may be an advantage – it does have a deterrent effect. Likewise, an obvious CCTV camera mounted outside your front door will make it clear to a would-be burglar that their exploits may be filmed for posterity. If, on the other hand, you want to be able to conceal your surveillance, there are many systems that feature sleek, small cameras that are easy to conceal, or that fit right into your décor.
Black and White or Color?
Color is not always your best choice for a surveillance camera. The majority of CCTV systems that film outdoors are black and white systems, sometimes with low light or infrared settings to capture images after dark. A color CCTV camera is more expensive, but will give you better detail and definition for indoor surveillance.
Wired or Wireless?
Wired CCTV systems are more expensive and harder to set up than a basic wireless security system. Unless you’re a skilled home handyman or use a contractor to install your system, you’ll have cables and wires running along walls and floors. Basic wireless systems are less expensive, but the coverage can be spottier and the pictures are often poor quality. The technology improves every day, though, so keep your eyes open for improvements that may make wireless CCTV systems much more desirable.
Resolution
The higher the resolution of the security camera, the better the picture quality will be. Unlike digital cameras, which measure resolution in megapixels, CCTV cameras measure resolution in lines, usually abbreviated as TVLs for TV lines. A basic security camera will offer 380 to 420 TVLs. Better quality CCTV systems include cameras that offer up to 570 TVLs.
Choosing among the many CCTV systems available depends on knowing what you need and how you’ll use the system. Talk with an authorized dealer to find out more about available CCTV systems that will fit your needs.
