Digital Video Surveillance
Video Surveillance refers to the use of video cameras to observe a subject or an area. In the past video surveillance systems were often analog, storing their output
on a VCR or other similar device. With the advent of the digital revolution some systems began using DVRs (Digital Video Recorders), which, after converting the
analog information to digital, stored the images/video on a hard disk or in large banks of RAM. Systems using either DVR's or video recorders have in common the
same security vulnerability. The storage media can be easily damaged or stolen. As digital technology progressed a more advanced system became possible.
IP Video Surveillance
IP Video Surveillance refers to the use of "Internet Protocol" (IP) to transmit digital surveillance images/video. This technique allows images/video to be instantly
transmitted away from the site, precluding individuals from damaging or stealing the archived information. In addition to making the data more secure, the data is now
more available for viewing and analysis.
