DVR is short for digital video recorder. Wireless Camera and Surveillance System
In today's world we all need to take precautions to protect ourselves, our families and our investments. The increasing amount of crime should lead us to consider the need to purchase a video surveillance system. But first lets cover a little history of Video Surveillance.
Systems were initially implemented for use for the police in big cities to control traffic and violence in the streets. Subsequently they began to be used in big business and banks, with cameras that sent the signal to a TV monitor where an operator could switch from one camera to another because only one camera could be seen at a time.
In the 70s multiplexers came allowing the monitor to be divided in four screens, VCRs that recorded the images on videocassettes and more elaborated cameras. These systems were very basic and very expensive.
In the mid-90s appeared the (Digital Video Recording) that can record digital images with higher resolution and allows tagging images with date and time, and access them from remote locations via internet.
Today cameras come with a lot of technological advances such as high resolution, color recording, day/night recording, among others.
