software, which greatly facilitates
and accelerates the whole process. All
system functions are provided at the
intersections by basic hardware with
appropriate licenses. This way purchase
cost, installation and maintenance costs
can be decreased.
The 20 megapixel camera generates
high speed, 20 FPS JPEG2000 video
stream, where even fast motions are
rendered continuous. License plates
can be recognised in the large-scale
monitored area. Together with the
integrated SensorTec IR Flash, the
camera provides suitable images
whether day or night. Images in the
SensorTec System are compressed
individually with visually lossless
JPEG2000 compression standard. The
embedded multi-resolution capability
of the JPEG2000 is a key factor of the
dynamic bandwidth management
function. Due to their wide dynamic
range feature, SensorTec ONE cameras
together with the infrared flashes
provide clear and sharp images of the
license plates even in most extreme light
conditions. Since the system provides
traffic counting information as well,
traffic flow can be effectively managed
both automatically and by real-time
operators in the monitoring room.
Violation management
If a vehicle breaks the traffic rule,
the video content analysis module
“SensorTec city
surveillance
functions
include real time
monitoring of
cameras, archive
playback as images
are recorded, fast
pan-tilt-zoom
camera control.”

automatically detects it with high
precision. It marks 5 corresponding
images that show the offending
vehicle and creates a violation package
that contains the automatically
cropped license plates as well. These
packages are then sent to the Violation
Management Center via WiMAX
wireless communication installed by
Infinet Wireless. “At the current
state of the project
70 intersections
have been equipped
with SensorTec
components.”
This unique architecture also allows
optimising the bandwidths from each
of the traffic junctions to the central
control rooms. This is performed by
pulling only the required data pixels
from the video images by using
JPEG2000 visually lossless compression.
At the same time SensorTec archives
over one month of videos on-site itself. and user-friendly VMS, the Control
Center software. The programme
provides functionality to access the
most detailed live videos of the situation
and watch archived footage.
The violation packages with the
processed camera images arrive at
the Violation Management Center via
high-speed wireless network provided
by Infinet Wireless. The Violation
Management Server manages the
violation packages, stores them
in a centralised database, and it
downloads several images of the
offending vehicle to a centralised
image container. It maintains
communication with the Automatic
Number Plate Recognition Server, the
Government database and transmits
violation packages to the violation
management clients.
Control room
In Cairo, two monitoring centres
operate within the SensorTec System
in two different locations. Both centres
are designed for real time operation,
but inside one of them the Violation
Management Centre has been set as well.
They are able to fully control the IP video
system in real time. Basically, one of them
is intended to concentrate only on city
surveillance tasks, and the purpose of the
other is to fulfil traffic surveillance. There is
5 GB, high-speed, wireless communication
line between the two monitoring centres,
provided by Infinet.
A huge video-wall and a couple of
workplaces serves the operators for real-
time monitoring at each control rooms.
They use the industry’s most reliable
In the Violation Management Control
Room, there are workplaces for the
operators and for the supervisor to
confirm the processed traffic violations.
The police officers use the Violation
Management Clients to confirm
automatically detected violations. The
user-friendly design of this software
ensures a daily 10,000 citations
throughput for each workstation. This
high performance is essential, because on
the streets of Cairo every camera could
detect thousands of violations every day.
The confirmed violation report can
be automatically exported for the
government summon issuing system.
This export contains every essential
information of the violation, such as
pictures about the violation, car data, date
and time, and violation types. The format
of the export is customer dependent, by
default it is an XML file. Additionally, the
SensorTec Traffic system can generate
a complete police report. This PDF file
contains images and violation details,
according to the user defined format.
SensorTec System is maintaining the
security in Cairo’s everyday traffic by
detecting and recording several types
of traffic violations and providing
irrefutable evidence for local authorities.
As drivers know their offending actions
could be captured, they will comply with
traffic rules. Such a well-functioning
system helps to improve traffic,
increased throughput of roads, reduced
traffic jams, and lowering of transport
time and costs. n
