Chicago is a city that has seen its fair share of crime. The city currently experiences a higher murder rate than larger cities, such as New York City and Los Angeles. Only 60 percent of murders in the Chicago area are solved. In general, Chicago has a higher than normal crime rate. Approximately 300,000 crimes are committed annually in Chicago with nearly 1 in every 30 residents becoming a victim. The security needs of homeowners in the Chicago area are going to be somewhat different than elsewhere. Residents of Chicago are more likely to be victims of burglary and theft than people in other cities. An alarm system can have a dramatic impact on the security of a home. A home with a security system is three times less likely to be burglarized. Stealth's home security solutions ensures Chicagoland security systems are installed properly so you maximize your return on all your security system investments. Wherever you work in and around Chicago, IL,Stealth's home security solutions will install your security system to manufacturer specifications and your personal satisfaction.

18. Risks/Contingencies
1. Wireless communication adds to
sensor interface complexity
*Remove wireless link from sensors.
Use simple wires.
2. Number of remote units increases
complexity
*Decrease number of remote units

19. 3. PC interface functionality of graphing
and displaying data
*Simplify the Visual Station graphing
functionality
4. Remote access via web server
*Simplify the web server or use the
Visual Station instead
