Charge Coupled Device (CCD) and Complementary Metal Oxide Semiconductor (CMOS) both have image sensors that are used for capturing digital images, but it is the technologies that are different. They each have their own set of strengths and weaknesses that give way to various applications. It is not as if one is superior to the other, but when you speak to vendors who only specialize in one of the forms of technology they will tell you that they feel otherwise. Throughout the last five years, there have been a lot of changes that have happened from both forms of technology. There are a lot of projections in regards to the demise of the technologies that have been proven false time and time again. Both forms of technology have a bright future, but there is still a need for the framework to be enhanced in regards to both of the CCD and CMOS imagers for their strengths and opportunities that they are going to be able to offer.

There are times when it is necessary to use a covert security hidden camera. Security Camera King offers a full range of hidden or disguised cameras, camera units that contain their own Digital Video Recorder or DVR, and high-quality low visibility powered microphones.
What exactly is a covert security hidden camera? It’s actually nothing more than a camera that captures digital video and audio (depending on the model) without the knowledge of the subject being recorded. The camera can be a standard sized digital video camera or it can be a very small disguised camera like our Phillips screw-head camera.
The Digital Video Recording Closed Circuit TeleVision system or DVR CCTV system is rapidly becoming one of the most popular security and surveillance documentation and monitoring tools in use today. Thanks to advancements in digital technology, not only is high-quality color digital video possible, but its also economically priced, easy to install, and versatile in application. In addition, these systems are even able to record clear videos in total darkness using infrared technology.
What is a mini CCTV camera? Arbitrarily we can say that a mini CCTV (Closed Circuit TeleVision) camera is any camera that is smaller than the majority of CCTV cameras sold as “Standard” sized cameras. But generally, when the term “mini CCTV camera” is used, reference is made to the small cameras normally used for covert recording.
Thanks to modern technology, anyone can own a mini CCTV camera. Just a few years ago, these cameras were so expensive they were cost prohibitive for the individual to own, if they were even available at all. Today, not only are they affordable but they come in a wide range of types, each designed to satisfy a specific purpose.
Infrared CCTV cameras are becoming one of the most popular types of security/surveillance cameras for residences and commercial applications alike. Before purchasing an infrared CCTV camera it’s important that you are familiar with some of the terminology and functions associated with this specialized aspect of a CCTV security system.
Most Closed Circuit Television or CCTV cameras today are digital cameras. Basically, they take pictures or video much the same way as a personal digital camera or camcorder. These cameras operate by allowing light to penetrate through an iris or variable opening, a lens, and then strike a Charged Coupled Device or CCD or a Complementary Metal Oxide Semiconductor or CMOS.
