  1. Personal Safetyand Alert Device CS 410 Blue Group Feasibility Fall 2010 Brittany Dufort, Daniel Cox, Marcus Henry, Braden Gibson, Ray Bland, Jon Szewczak

  2. Societal Need • In the event of a personal 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.

  3. Impact • First Responders • Must rely on victims reporting accurate location data after or during a traumatic event. • Victims • Must be aware enough to make a phone call to emergency dispatch personnel. • Larger Populace

  4. 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.

  5. Benefits of Solution • Cuts 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.

  6. 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

  7. 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. * Data for 2009 and 2010 has not been collected, but it is reasonable to assume that the statistics are similar.

  8. Old Dominion University • The interest in the concept is very high. • A couple of weeks ago, two team members met with ODU Police officials, and were shocked at the eagerness that was displayed. • There would likely 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.

  9. 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.

  10. Financial Issues (Hardware) • Each key fob has a nominal price of $20. • Uses Nordic Key Fob (model no. WRL-08602) as a base line • Each transceiver has a nominal price of $16. • Uses Nordic Transceiver (model no. nRF24L01+) as a base line • Does not include a NEMA-3 rated enclosure • Rough order of magnitude for quantities required: • Fobs = 4,500 (approx. # of students living on campus) • Transceivers = 5,000 (to maintain coverage over most important areas)

  11. Financial Issues (Hardware) • $20 (cost of Fob) x 4,500 (# required) = $90,00o • $16 (cost of transceiver) x 5,000 (# required) = $80,000 NOTES: • Cost of Fob could be passed on to students as an extra fee, or incorporated into housing fees. • The price of an adequate NEMA-3 or NEMA-3R enclosure was unavailable at the time this presentation was put together.

  12. Financial Issues (Software) • Two distinct areas of software development: • GUI interface for dispatchers • Firmware interface for hardware • Rough Order of Magnitude Estimates: • 400 – 600 man hours for GUI interface • 300 – 400 man hours for Firmware interface • Use a median value of $100 per hour (loaded) rate • $70,000 – $100, 000 worth of software development costs

  13. Financial Issues (Software) • Costs for initial software development are estimated. • Recurring maintenance and upgrades would be substantially less.

  14. Financial Issues (Miscellaneous) • Installation costs have not been addressed. • Customer will have to provide extra training for dispatch personnel on the use of the monitoring software. • There are equipment maintenance issues (i.e. battery replacement, faulty equipment replacement, etc.)

  15. Financial Issues (Summary) • $100,000 for initial software development • $160,000 for hardware • $260,000 total estimate of initial outlay • Unknown amount for other major line items NOTE: • These figures are not split between the customer and developer. • As previously noted, some costs could be passed on to the students in the form of additional fees.

  16. Project Team • There are 6 members of the Project Team • R. Bland () • D. Cox (Web / Presentation) • B. Dufort (PM / Software) • B. Gibson () • M. Henry (Hardware / Financial) • J. Szewczak (Hardware / Presentation) • Roles are defined by the skills and preferences of the team members.

  17. Project Team • Communication Methods • Team Members meet face-to-face twice a week • Out-of-class meetings utilize Google Chat services • One of the team members takes notes on the topics discussed during the meetings and post them to our project wiki.

  18. Risk Management • Financial • Technical • Legal • Possible Misuse / Deviant Usage

  19. 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.

  20. Technical Risks • FCC Guidelines / Licenses • Possible interference from other broadcasting devices (i.e. cell phones, baby monitors, etc.) • Mitigated by proven radio technologies

  21. Legal Risks • Device fails to send an alert to the monitoring authority – introduces possible liability issues

  22. 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.

  23. 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
