What is a video encoder?
A video encoder (also referred to as video server) digitizes analog video signals and sends digital images directly over an IP network, such as a LAN, intranet or Internet. It essentially turns an analog video system into a network video system and enables users to view live images using a Web browser or a video management software on any local or remote computer on a network.
It allows authorized viewers from different locations to simultaneously access images from the same analog camera, as well as network cameras if they are added to the system.
An IP-based surveillance system will give you the ability to secure people and property, or monitor equipment and facilities, remotely from anywhere there is a networked computer. In addition, by utilizing the serial ports of a video server, you can remotely control existing equipment such as pan/tilt/zoom devices or time-lapse tape recorders. A video server can be connected to a wide variety of specialized cameras such as a miniature or microscope camera.
Computerized monitoring lets the computer do all the searching, only notifying security when it perceives a problem through analysis of its own data.
Another CCTV advancement has been with individual tracking. Security cameras are limited to the directions they can point, and the visible area within those directions. When a person goes out of the range of the camera, they are no longer visible. But more advanced CCTV technology allows these security cameras to pick up where one camera leaves off, following the person as they move from visible area to visible area.
CCTV advancements can pick up actions, such as fights or loud noises, and tell the security cameras to focus on these actions so that the sound and activity can be more easily viewed. Cameras can be automatically programmed to move and zoon in towards the commotion in order to get a better view of what is happening. Technology for CCTV cameras and systems has come a long way over the past several decades. What originally was a basic way to monitor security cameras all in one place has advanced to become its own data system that allows for easier management, greater monitoring, and improved crime prevention. As things like VCA continue to evolve, it will not be long until it becomes extremely difficult to get away with any illegal activities without getting caught.
