Security camera systems are widely used in both residential, commercial and industrial settings. If you are thinking of buying a security camera system, it is important to know the technical terms that you will hear when looking for a security system. Otherwise you aren’t able to effectively communicate with the sales people. For instance, firewire camera is likely the jargon you’ll hear about. A security camera system is referred to as a CCTV system. For example, if you are offered a Sony CCTV camera then you will immediately know what you are being offered and won’t have to ask!
One thing you should know is the Charge Coupled Device (CCD) which is basically the technology used for security cameras. The CCDS take the images that the camera captures and transfers them to electronic impulses.
You should also know how camera formats are measured. Basically, the are discussed in inches and the majority are either ¼” to 1″. In most CCTV systems the security system will use either ¼” to 1/3″ without sacrificing any quality.
Color and resolution are other factors you need to consider while shopping for a CCTV. Security guards can determine what the individual is wearing and what they look like much better with a color camera than with one that is black and white. Resolution is important because it will determine how detailed the pictures the camera receives are.
