Tracer
The Tracer devices come in three versions, fixed, semi-fixed or mobile. Fixed and
semi fixed are attached to objects while mobile is carried by a person. The mobile
unit is battery-powered while the others may be mains and/or battery powered. Tracer
uses a positioning system to pin-point its location and a communication system to
convey its information.
The Tracer is a generic device suitable as a platform for a number of sensors, thereby
inviting third-party sensor manufacturers to develop sensors for diverse applications.
Typical applications areas where Portendo will partner in developing end-user products
are people and luggage screening systems and detectors used in military vehicles.
Maintenance is easy and cost efficient. Software updates can be performed automatically
over the communication network.
The communication between the Tracer and the Portendo OPC use advanced access control
to stop tampering, encryption to block eavesdropping and de-localization transmissions
to mask the occasional threat transmissions.
The processing unit utilizes the information gathered from the sensor unit to identify
if one or more substances are represented in the air sample. This is done by comparing
the results from the sensor with a signature database. If a match is found, the
device will use a positioning system (e.g. GPS) to establish its location and report
the findings over the chosen communication network (e.g. GSM network).
