Closed-circuit television video security cameras have come a long way ever since being first launched into the market in the late 1960s. There are all types of CCTV video cameras today for example dome cameras, bullet cameras, IR video cameras that can scan at night and even tiny small pen cameras like in the James Bond movies. The security camera business has become one of the fastest growing industries in recent years since Sept 11th. Analog and Internet protocol video cameras are the two kinds of Closed-circuit television video cameras offered presently on the market. Although analogue Closed-circuit television video cameras are still the most widely used type, the functions and flexibility that end-users & corporations can benefit by utilizing Internet protocol Closed-circuit television systems compared to analog are immense. Some features include, video cameras running on power over Ethernet (POE).

What this means is that the camera can be powered and transfer video feed by using one Cat5 cable, rather than operating a power cable and a separate video cable the way that analogue cameras do. Another advantage of using IP CCTV cameras is that the quality that can be attained far surpasses the video quality that can be delivered while using analogue technology. IP cameras resolution is calculated in digital megapixels as opposed to TV Lines (TVL) as standard analog video cameras do. What this means to the users is a clearer, crisper, and more detailed image than what is achieved using analog. With the launch of IP cameras there came another method of recoding and saving footage taken by CCTV systems. The Digital Video Recorder also known as a DVR is used to take footage or video taken with a security camera and storing it as the label says, digitally, onto a hard drive.

Now users can view up to a months worth of video footage on a Digital video recorder without having to change old VHS tapes for certain days as was done in the past. IP video cameras also known as Internet Protocol cameras use Network Video Recorders in order to record footage which can then be viewed remotely from anywhere that has an internet signal. Currently folks can even watch a CCTV transmission via their own internet enabled smart phones. With this feature customers can have more freedom and a better sense of security knowing they can browse their CCTV system anyplace. But with all the perks in which IP CCTV camera technological innovation can deliver there is a downside; because IP technology is still new to the industry the cost of setting up an Internet protocol security system remains to be significantly higher than going with an Analog Closed-circuit television System. With the rate of how quickly technology improves in todays age, analog cameras are still very capable of delivering the convenience, safety, as well as security that customers have come to expect at a lower cost than IP.
