Numerex Announces OrbitOne(TM) Next-Generation Satellite Tracking and Asset Monitoring Solution

October 23, 2007

Long Life, Low Cost Satellite Solution Delivers Supply
Chain and Logistics Tracking for Military, Government and
Commercial Markets


    ATLANTA, Oct. 23 /Xinhua-PRNewswire/ -- Numerex
(Nasdaq: NMRX), a leading single-source provider of
solutions and networks for Machine-to-Machine (M2M)
applications, today announced the commercial release of the
OrbitOne SX1 solution, a breakthrough in satellite-based
asset monitoring and tracking technology.  Operating on
Globalstar's Low Earth Orbit (LEO) simplex satellite data
network, the OrbitOne SX1 provides GPS visibility, event
monitoring and asset management data on a near global
basis.  

    Developed by Orbit One Communications, Numerex's
recently acquired satellite solutions business, the SX1 is
one of the smallest satellite communication devices in the
industry with a footprint of only 7.25 x 3.25 x 1 inch (184
x 83 x 25 mm) and weighs a mere 13 ounces (369g). 
Delivering up to seven years of uninterrupted service on a
field-replaceable battery, or operating on line power, the
SX1 provides mission critical reliability under the
harshest environmental conditions.  Certified and
manufactured to exceed IP68, NEMA 6P, and MILSTD 810
environmental specifications, the highly-ruggedized device
can be installed, activated and operational in less than
one minute.

    For systems integrators the SX1 provides a reliable and
open data architecture compatible with virtually any legacy
supply chain, logistics or tracking application making it
the ideal choice for the security, management and tracking
of military, government or commercial assets such as
inter-modal shipping containers, trailers, buoys, or
barges.  The OrbitOne solution is also capable of providing
global supply chain logistics visibility, resulting in
reduced demurrage, increased security and minimized fleet
downtime.

    "We are very excited about the launch of OrbitOne
SX1, which we believe is a ground-breaking achievement. 
The solution provides our military, commercial and
government clients with true visibility of their mobile
assets nearly anywhere in the world - we think of it as
Global RFID," comments Stratton Nicolaides, chairman
and CEO of Numerex.  "For large scale and global
deployment OrbitOne offers one of the most cost-effective
solutions available and complements our existing cellular
tracking and monitoring platforms.  The solution also
extends our global reach and positions Numerex to offer our
military, commercial, and government customers a broader
range of device and network communication options."

    Originally developed and deployed for the military and
disaster response communities, the SX1 expands the
satellite and cellular network services that are monitored
and managed through the company's TAV (Total Asset
Visibility) application.  This comprehensive tracking and
monitoring solution provides secure mapping, display, and
management tools for tens of thousands of global assets
from any internet connection worldwide.  In the next few
months Numerex intends to introduce an accompanying
portfolio of sensor options to meet customer demands for
additional real-time security and intelligent monitoring.

    Orbit One Communications, the developer of the SX1 and
TAV Software, was recently acquired by Numerex.  The
company is a recognized leader in satellite tracking
solutions that offer visibility and event monitoring for
emergency management, global supply chain logistics, and
field asset and personnel tracking.  Orbit One is the
supplier of satellite tracking solutions to DHS-FEMA, the
American Red Cross and prime contractors to federal and
state agencies for disaster and emergency response
operations.

    The SX1 is commercially available now through Orbit One
Communications LLC, a wholly-owned Numerex subsidiary, with
a multi-year warranty to end users, systems integrators and
value added resellers.  For additional product information
