What's the difference, CMOS vs CCD? In the digital video security camera industry there are two types of sensors used to convert light images into (ultimately) electronic images. Those two sensors are the Complementary Metal Oxide Semiconductor or CMOS and the Charged Coupled Device or CCD. In the following article, we'll take a closer look at each and see how they are both similar and different.
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.
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.
