Digital security surveillance system

A video surveillance system, comprising:

• a plurality of input devices that receive video signals from video surveillance feeds in the video surveillance system;
• at least one storage device in communication with the video surveillance system;
• a video signal storage device, implemented at least partially in hardware, that stores each video signal of the plurality of video signals on the at least one storage device as a digital video signal;
• a first subsystem, implemented at least partially in hardware, that, in response to receiving a command to view a specific video surveillance feed, extracts a digital video signal for the specific video surveillance feed from the at least one storage device;
• a second subsystem, implemented at least partially in hardware, that simultaneously sends the extracted digital video signal and a real time video signal of the plurality of video signals to a display device, content of the extracted digital video signal is different from content of the real time video signal;
• and
• wherein the sending subsystem further comprises:
• a third subsystem, implemented at least partially in hardware, that switches between stored digital video signals and real time video signals of the plurality of video signals in response to receiving a command to view specific video surveillance feeds.
