The major part of the surveillance
system forms the main control centre. Here all available
information of the surveillance sensors are collected,
processed, analysed and stored. The main goal is a reliable
fully automated alarming system. The PSS-20-04 system is
designed to meet this challenge especially when different kinds
of a photonic sensors are used. To process the variety of
surveillance sensors like cameras, Laser light barriers and IR
motion sensors a sophisticated combination of hard- and software
is required. The Synoptical Panel provides all these means for a
fully automated visual control of each corner of the area under
surveillance. |

The software
covers two major parts:
Synoptical Control
The visible part of the Synoptical Control is a map of the area
under surveillance. In this map all kinds of sensors are shown.
Via an alarming bus all sensors except the cameras are connected
to the microprocessor based Alarming Unit. This unit
sequentially polls the surveillance sensors. In case of an alarm
the map is zoomed to the specific location of the sensor caused
the alarm. Furthermore, the video control is instructed to show
the image of the camera which is located closest to the sensor.
Visual tools are provided to place the individual sensor as well
as camera with respect to their actual position within the area
of the map. Furthermore, each sensor is provided with a unique
identifier.
In case of an alarm the area map is zoomed in such a way that
the place of intrusion is shown.

Video Control
The Video Control section is responsible for the camera section.
The cameras are connected to the video boards, which are
initialised and controlled by the video control software module.
The image processing software module sequentially collects the
camera images and performs for each image the motion detection.
Hereby it compares the actual with a reference image. In case of
a significant difference of both images an alarm is generated
and passed to the Synoptical Control. The map is zoomed to the
particular camera and the Video Control switches the display to
full screen mode as shown in the figure on the left.
Furthermore, the recording of the camera pictures starts, unless
it is stopped by the user. The video sequences are stored on the
harddrive of the video processor for later analysis.
The Video Control software also operates the remote zooming,
panning, and tilting of cameras equipped with these facilities. |
