T-DAR®
(Tailgate Detection, Alarm and Recording) System
Features:
The
patent pending Newton Security T-DAR®
system uses Newton's proprietary 3-Dimensional
optical tracking system as the primary technology
to track personnel passages though a secure door.
This optical tracking is combined with other sensor
technologies developed at Newton to provide a
very robust tracking system. The main features
of the system are:
1.
Accepts data from virtually any badge or pass
system including biometrics and smart ID systems
for an authorized entry.
2.
Confirms the transit of only one human for each
pass entry, while allowing for carts, parcels
and other non-human objects.
3.
Alarms and records the violator in real time video
for any violation of the rule of one human per
authorized entry. In addition the time and pass
number used for the authorized passage are recorded
with the video.
4.
Communicates to the central security system in
real time the alarm condition and the recorded
video over a video link or a digitizing link such
as Ethernet.
5.
Installs with no modifications required to the
portal and allows the swing of the door to be
into the secure or the public side of the portal.
Operational
Details:
The
Newton T-DAR® system detects movement
in or around the secure side of the portal with
Newton's proprietary motion video and then utilities
Newton's sophisticated Machine Vision technology
to identify and tag each human within the field
of view of the tracking (overhead) camera. It
maintains that tag on that person so long as he
or she (or some portion of the person) remains
in the view of the camera. That information is
than combined with the data provided by the access
device, door contacts and other input data to
determine if the tagged person is a legal transit
or is a tailgater.
The
Newton T-DAR® system is extremely
powerful, operating with 3 microprocessors (including
1 high speed Pentium class processor) and is easily
able to execute any desired logic pattern combining
the input data with it's position and direction
knowledge of the tagged persons to detect illegal
behavior around and/or in the portal. The frontal
view camera is capable under software control
of the system to provide video from full time
(as would a simple CCTV system) to event only
video. In addition, the system also provides local
digital recording and the ability to send to a
remote station any desired segment (including
full time) of that video, either in Ethernet or
NTSC format.
The
Newton T-DAR® system is highly
configurable, including reconfiguration on the
fly from a remote processing center (such as a
central security station). The standard configuration
for airport portal control is as follows:
Stage 1. Door Closed-No activity from Access Control
system
Tracking
Camera active, tagging persons in the field
of view of the camera (secure side of portal).
Frontal View Camera running a continuous non-permanent
loop of recorded video with time and date stamp.
No other system activity.
Remote system can activate remote control to
view Frontal View Camera video at any time for
real time video of secure side of the portal.
(T-DAR® system emulates CCTV
system).
Stage
2. Door Contact or Access Control activity
Tracking
Camera active, tagging persons in the field
of view of the camera (secure side of portal).
Frontal View Camera running a continuous non-permanent
loop of recorded video with time and date stamp
and the pass number of the person who activated
the Access Control system.
Logical determination of legality of persons
transiting the portal, portal open time and
other predetermined criteria.
A.
If no illegal behavior is detected, no further
system activity. Video stored in local continuous
loop only. Return to Stage 1.
B.
If illegal behavior is detected:
1.
Local alarm is sounded. If the person
returns through the portal and portal
closes with no other illegal behavior
present, system returns to Stage 1.
2. Frontal Camera video is semi-permanently
locally stored for later review in the
system, with time and date stamp and the
pass number of the person who activated
the Access Control system. Recording to
be semi-permanently stored takes place
for the period of time as motion is present
in the view of the camera and/or the portal
remains open.
3. An alarm and real time video with time
and date stamp and pass number of the
person who activated the Access Control
system is delivered to a remote station.
Remote alarm and video period can be controlled
by the remote station, terminated when
the portal is closed and no other illegal
activity is detected, and/or for a pre-determined
period of time.
