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.

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.
There are times when covert camera monitoring and recording are necessary and one of the best devices for this purpose is a hidden camera with SD card. Thanks to recent technological advances in the computer world as well as in general electronics, a camera can be made as small as to fit in the shell of an average writing pen.
When it comes to the appearance of a hidden camera with SD card, there are many types from which to choose. These cameras come in “bare-bones” mini versions, where the camera is basically undisguised but is small enough to be hidden, to disguised versions that look (and often times function) as clocks, mirrors, safes, stuffed animals, and many more.
The term “digital surveillance software” refers to a broad category of computer based sets of instructions that provides the instructions for either a computer or a computer based device to operate, control, and/or process binary (digital) data used or created for security and surveillance purposes. To narrow this definition down a little for the purpose of this article, digital surveillance software is the collective set of programming used to create digital video images for security and surveillance purposes.
One of the more recent digital video security camera system components is the wireless IP security camera. These cameras use the Internet as a network medium for the purpose of transmitting their digital video images and for allowing the user to control the camera remotely. This places the maximum power of remote accessibility as well as easy installation in the hands of the user.
It seems as if all of our electronic devices today utilize or have some sort of affiliation with, the Internet. So why shouldn’t the digital video security industry take advantage of its seemingly ubiquitous presence and cost-efficient use as well? That’s exactly what a wireless IP (Internet Protocol ready) security camera does.
