Background
 In times of need people call 9-1-1 for emergency
assistance.
 Personal Crimes (i.e. Robberies, Assaults)
 Accidents and/or Injuries
 Existing security paradigms rely on verbal
communication with people in need – which usually
comes after the event has occurred.
 During a personal crime the victim often cannot call 91-1 for fear of aggravating the assailant.

Societal Need
 In the event of a personal crime or emergency, security
professionals at higher education, business and civil
complexes need an effective way to allow individuals to
quickly and silently communicate their location to first
responders.
26-Jul-16
5
Proposed Solution
 Individuals would be equipped with a key fob.
 Pressing a button or combination of buttons would
trigger an alert at a security dispatch center.
 The alert would be repeated every 30 seconds until
first responders reset the unit.
26-Jul-16
6
Benefits of Solution
 Aids in improving response time
 First responders do not need location information from
victims.
 Victims do not have to fumble around for a cell phone and
dial a number; a button push is all that is required to summon
aid.
 If the victim is moving (i.e. on the run), the system will
report their movement.
 Based on proven technology.
 Could act as a deterrent.

Determining Customer
 Many possible customers:
 Universities or Colleges
 Business complexes (i.e. Google, Microsoft, Intel, Trump
Tower)
 Civil complexes (i.e. the Capitol Building)
 Scoping Issues
 Due to time constraints the focus will be on Universities.

In particular Old Dominion University

Old Dominion University
 Spends approximately a $262,000.00 on security every year.
 Personnel, Security Devices, etc.
 In 2008
 10 personal crimes on campus
 2 in residence halls
 4 off campus
 46 in the surrounding neighborhoods
 That averages 1 crime per week for the entire year.

Old Dominion University
 The interest in the concept is very high.
 A few weeks ago, two team members met with ODU
Police officials, and were surprised at the eagerness that
was displayed.
 There would be very little financial return on
investment. However, the ability to make students,
staff, and faculty a little safer could be considered an
adequate return.

Technical Aspects
 Radio based
 Key fob alert units (approx. 100’ range).
 Transceivers stationed to give maximum coverage to
the most logical areas (approx. 330’ range).
 Relay Transceivers
 A master receiver which would interface with the GUI
at a dispatch station.
 A software suite (most likely based on the Google
Maps API) to provide a GUI for dispatch stations.

Process Flow Diagram
Through a series
of transceivers
that signal would
be translated to
dispatch.
When a fob
button(s) is
pushed a signal
would be sent
out.
The dispatch
station will
have a graphic
user interface
that maps the
location of the
emergency
beacon.
Once activated the fob would
automatically repeat its
broadcast until reset by
responders.
Dispatch would route a
responder at a high
priority to assess the
situation.

Risk Management
 Financial
 Technical
 Legal
 Possible Misuse / Deviant Usage
26-Jul-16
35
Financial Risks
 There is a substantial initial outlay
 Potential recovery of costs for customers is marginal
 Project puts emphasis on safety and not commercial
viability
 Unless hardware costs can be controlled, the system
may preclude smaller institutions.
 Setting up transceivers may need a large labor force.
 Possibility of running into Unions
26-Jul-16
36
Financial Management
 The system is expensive, yet the clients we market to have
ways of helping to offset this cost.
 Old Dominion University has an annual tuition rate that
incurs for every student. Part of this fee goes towards campus
safety.
 In terms of budgetary oversights, we plan to have SBIR
funding in the grants section. This along with outside
investment should allow some leeway for budget
constraints.
26-Jul-16
37
Financial Management
 Staffing is an issue, and we will have to work with unions
when the time comes for installation.
 Virginia is a right-to-work state therefore unions will not
constrain our venture.
 The recurring cost issue is one that only comes up when
new employees or students matriculate to the university or
complex. The initial system itself (the transceivers) is
already intact. Therefore recurring costs will not be as high
as the initial outlay and can easily be covered by tuition or
new employee safety fees.
26-Jul-16
38
Technical Risks
 FCC Guidelines / Licenses
 Possible interference from other broadcasting devices (i.e.
cell phones, baby monitors, etc.)
 Mitigated by proven radio technologies
 There is also a probability that hackers or trouble makers
may find ways to use our system aside from its proper
function.
 Another issue is that our system will rely on signal
propagation or piggybacking and it may be hard to find
technical experts to help on this venture.
26-Jul-16
39
Technical Mitigation
 The FCC has information readily available online about what
frequencies are available to businesses. As can be seen from our
milestones, we will test what frequencies our system is able to use and
run it by the FCC for approval.
 The issue of radio interference is another aspect of our milestones,
while testing the frequencies we will make sure that they do not
interfere with other businesses.
 It is always possible for people to find ways to achieve mischief; as such
we will make sure that the signals sent out by our fobs are encrypted so
that only our transceivers will pick them up for transmission relay.
 We believe that the use of Old Dominion University professors well
versed in signal processing and transmission will enable our project to
move forward with the aforementioned transmission methods.

40
Legal Risks
 Device fails to send an alert to the monitoring
authority – introduces possible liability issues
26-Jul-16
41
Possible Misuse / Deviant Usage
 A lost alert device could be used by a criminal element
to distract monitoring authorities from a real event.
 System is used to pull pranks, instead of alerting first
responders to a real emergency.
26-Jul-16
42
Scope
 Since the project is very large, it will have to be broken
down into a more manageable chunk.
 Customer – Old Dominion University
 Hardware – a working prototype communicating with
software
 Software – a working GUI interface for mapping the
location of the alert
