Buying Your CCTV Camera Security System

Security is a major concern for many homes and offices, a concern that may be addressed and corrected by a properly installed CCTV camera security system. A CCTV camera security system can provide one of the best monitoring equipment for any home or office building, primarily because it offers 24/7 security monitoring without the need for hiring too many personnel to do the job. Here's how you can choose a CCTV camera security system that is just right for your needs:

Consider if you truly need it. A CCTV camera security system is a very effective security device but it can be a very costly investment. Consider other deterrent tools such as lights, locks, alarms, fences or guard dogs before you purchase a security system. It might just save you a lot of money, time and effort.

Know the components. A CCTV camera system is composed of several equipment: cameras, monitors and recorders. There's also the cabling necessary to connect the whole system. Once put together, this system can be an effective deterrent and monitoring device to keep your home or office safe.

The surveillance camera is the unit you place to monitor areas you want to secure. Depending on your needs and on the area you need to cover, you'll probably need to buy one or two cameras or as many as 16 or more. Cameras may be either black and white or colored units.

You might also want to consider resolution, signal-to-noise ratio and light sensitivity. Resolution determines how detailed a picture your camera can capture while signal-to-noise ratio indicates how well a camera can transmit picture information as opposed to static. Light sensitivity indicates how well the camera can transmit images in different levels of lighting.

The monitor is the part of your CCTV camera security system that lets you see everything your cameras see. Although this is where you will be able to monitor the areas covered by the cameras, a monitor is often not a major buying decision.

The one thing you should remember about security system monitors is that they should be able to handle enough resolution and heat. Monitors will be turned on for many hours a day, something that an ordinary television may not be able to handle.

When choosing a monitor, buy one in a size that will show images effectively. For a monitor handling feed from a single camera, a 9" TV will do, provided someone is directly monitoring it. For a single monitor handling simultaneous multiple feeds from different cameras, buy one that is at least 15" big.

The recorder helps you store the images caught by the CCTV camera, an important function that may help you provide evidence or reference later. Older CCTV camera security systems used VCRs to do the job, although the more recent models make use of DVRs or digital video recorders. These let you record directly to a hard drive, which makes it more convenient to store and locate events for future reference.

The standard cable used for most CCTV camera security systems is the coaxial cable, the same type used with most video equipment. However, there are other types of cabling used, which may depend on the units you are using. Some cables, such as UTP or unshielded twisted pair types, may offer better monitoring because they provide less interference from electrical currents. Furthermore, they are also cheaper than standard cables.

You can also opt to go for a wireless CCTV camera security system, something that offers easier and less messy installation. The only challenge with wireless systems is that they are affected by interference from other electrical equipment.

Is a low-cost security camera system package worth it? Be wary about CCTV camera security systems being sold at very low prices. Very often, dealers throw in several low quality components to attract buyers who are looking for low budget systems. You might end up with a security system that may not be durable or reliable at all.
