Site Security System NS3-CT
The
Navtech Site Security System NS3-CT is designed to provide automatic
perimeter security for airports, ports, large industrial sites,
and other high value installations. Using a networked array of overlapping
Navtech security radar, the whole perimeter and internal area can
be monitored from a single central control and display unit. With
the addition of the CCTV interface, targets can be tracked and viewed
without any user interaction.Based on the Navtech 'W series' security
radar, the NS3-CT monitors stationary and moving targets up to a
range of 800 meters from each sensor, in all weather and light conditions.
See specification for specific target detection ranges.

How Does
It Work?
Each radar system constantly scans a full 360º across the
entire designated area, from close range up to 800m.
If objects are detected in the preprogrammed alarm zones, the NS3-CT
will command the CCTV cameras to focus on these. Capable of detecting
multiple intruders in different areas simultaneously, it can also
be configured to trigger audible alarms or activate other security
equipment.
Advantages
Enhanced site
security. With fully automated detection capability, the NS3-CT
removes the possibility of human error caused by a lapse in operator
concentration.
Very difficult to evade.
Continuous tracking of target allows intelligent assessment of intruder
threat.
A simple and easily understood display of all detection data can
be overlaid
on the site map.
A rapid and low cost installation which can be used for temporary
or permanent applications.
Can be used where other security systems are not practical e.g.
over water.
Reduced manpower costs. Only one person is required to supervise
operations.
Manned patrols can be reduced or eliminated.
NS3-CT system features:
Configurable
to identify objects above a given size, so that irrelevant background
movements are filtered out.
Discriminates between threats and background clutter based on heading,
speed and geographical area.
Detects small objects including a walking, crouching or crawling
person.
Provides a record of movements over time across the entire survey
area, or it can focus on specific areas, for example the walkways
between buildings.
Directs a CCTV camera to a detected threat and automatically control
the camera to follow the threat in head/shoulders or wide area settings.
Records avi files and raw data sets or screen shot bitmaps.
Overlays a detected intruder position on a background map or aerial
photo of the area.
Selectable zones of interest to display in the field of view.
Assigniment of detection zones, providing different levels of alarm
in sensitive areas.
Assignment of non critical zones to allow for normal site operation.
Automatically compensate for background changes to the environment
e.g. moving trees, grass etc.
The system calculates heading, position and velocity of intruders
and plots their track.
