M3S - MultiMedia Monitoring and Surveillance

Developed for Polixel S.A (June 1999 - October 2000)

M3S Objectives

Provide software and hardware tools for remote:

surveillance of still or moving objects using digital video;

monitoring sensor states for alarms;

voice communication between system operators and other staff members.

M3S Architecture

The system has an opened architecture. It is based on two basic system modules:

MultiMedia Concentrator (M2C) – a hardware unit which concentrates signals coming from local sensors (cameras, microphones, alarm sensors etc.) optionally joined with speakers;

Operator Program (OP) – a software unit which implements operator interface to video streams, audio streams and alarm signals for the overall computer network.

From the network point of view, the system has the client-server architecture. It is based on TCP/IP and UDP data transmission protocols. The multimedia concentrator is a server of digital signal streams which are requested by operator programs which are clients in this system (see figure below).

Family of products offered for M3S

The M3S system can be built from independent hardware and software components. They are defined to meet users needs and desired costs. The products are categorized by the features of the video sensing and video recording subsystems. The hardware requirements on the CPU, RAM, graphics and disc capacity are easily met by currently sold low-cost computers.

  1. Video subsystem located at the concentrator:

    Live video with all cameras observable at one time at the concentrator (up two four cameras per M2C)

    Live video with switching cameras (up to four cameras observable at one time at the concentrator out of up to 128 cameras)

    Slow motion video with one camera observable at the concentrator

    Slow motion video with switching cameras (one camera observable at one time at the concentrator out of up to 128 cameras)

  2. Video recording subsystem:

    video recording at the concentrator (to a local secondary memory by overwriting old data)

    video recording at the remote database (to a remote secondary or tertiary memory)

    on line video recording at the operator site (to a local secondary memory)

  3. Video subsystem at the operator:

    Live video with online controlled camera (required life video at concentrators controlling cameras)

    Live or slow motion video from still cameras (up to four observable windows)

  4. Audio subsystem:

    one way voice communication

    two way voice communication

  5. Alarm signaling subsystem

Graphical User Interface

For the user/operator, the only entry to the M3S is provided by the operator interface program. It presents to the operator a collection of hierarchically structured region, terrain, and building maps (see left top window in the figure below).

By mouse clicks, he/she can easily navigate from one site to another site reaching to icons representing signal capturing devices, such as cameras, microphones, and alarm devices.

Location searching can be accelerated if the operator clicks on tree representation of maps. The representation is organized in a similar manner to the computer file catalogues in Windows system (see top right window).

The lower frame of the right top window above includes the system log.
