System Definition for Digital Video Security Systems

      Described is a hardware implementation that defines a Digital
Video Security System (DVSS) which provides remote video surveillance
through the use of video compression algorithms.

      The DVSS eliminates the need for special networking
infrastructures and provides selective viewing area motion detection
for criminal trespassing detection.  It also provides for remote
personal alarm notification as well as local police notification.

      The DVSS is designed to exploit the intrinsic properties of
digital video compression technology combined with land-based modem
transmission facilities to provide a security system with the
following features:

1.  Motion detection based on intruder detection with user defined
    areas of activation within the viewing field.  It enables
    authorized motion within the motion detection field of view.

2.  Remote personal viewing of protected areas using standard phone
    lines.  It provides portability of the remote viewing feature.

3.  Remote personal alarm as well as local police notification when a
    protected area is invaded.

4.  High quality still images and video capture, plus audio capture
    of an intrusion event stored locally.  It provides superior
    quality for positive identification of trespassers.

5.  Lower quality still images and video capture, plus audio capture
    of intrusion event stored remotely.  It is impossible for
    criminal trespassers to corrupt captured video and audio if the
    security mechanism is discovered.

      In prior art, security systems, including burglar alarms, were
based on detecting circuit breaks associated with windows and doors
being opened when not expected.  Motion detectors sent alarm
notifications when movement occurred within the area of the motion
detector mechanism.  Burglar alarms typically were based on vibration
detection to detect intruder entry caused from window breakage.
Video surveillance systems had a special cable infrastructure
installed to connect with a remote surveillance office.  All of the
prior art items were effective to a point, but all had their
drawbacks in terms of effectiveness and cost.  The concept described
herein improves on the prior art systems through the use of the DVSS.

The DVSS consists of the following elements:

    a.  Surveillance Camera Enclosure (SCE) - Intended to be mounted
        in a position within the area to be monitored.  Typically in
        an upper corner of the ceiling.  The SCE includes the
        following components:

            -   Video camera with wide angle lens suitable for
                capturing the entire field of view of the area to be
                monitored.

            -   Video code that can compress the video image to an
                approximately 11 Kbps...
