 We are deeply indebted to Preetpal Kang for his invaluable comments and assistance in the development of this prototyping project. We’d also like to thank Steven Yu for his advice and feedback in the PCB design process.
-== Introduction==
+== Introduction ==
 The project is a wireless home and small-business security system. This section describes the background of the project, and what the expected impact will be.
 === Problem Statement, Project Motivation, and Needs ===
-==== The Need for Home Security ====
+===== The Need for Home Security =====
 There is a strong need for security in home and small-business applications. The FBI reports that burglary is the most common threat to a homeowner. Consider a few facts [1]:
 * Over 2.5 million intrusions happen a year, and this is on homes alone
@@ Line 20: / Line 20: @@
 It is incredible that 83% of the public is without a security system in their home or business, when it considerably enhances the safety of the property and residents.
-==== The Past: Traditional Security Systems ====
+===== The Past: Traditional Security Systems =====
 It is no surprise that so many families and businesses are without a security system when looking at the high costs from paying a company to install a traditional security system and receive security alerts. Security systems, by companies such as ADT, start at around $40 a month and often have an installation fee exceeding $300 [2]. This is very costly for homeowners and small businesses who want to maintain low overhead.
-==== The Present: Low-Cost, User-owned Security Systems with Monthly Payments ====
+===== The Present: Low-Cost, User-owned Security Systems with Monthly Payments =====
 There is a strong need for lower cost security systems that don’t require paying the exorbitant fees that a big security company charges. Cheaper, reliable alternatives are starting to become available, but even these services have a monthly fee. SimpliSafe is a company that allows the customer to easily purchase and install a wireless security system in their home or business, but there is still a $15/month fee [3].
-==== The Future: Low-Cost, User-owned Security Systems without Monthly Payments ====
+===== The Future: Low-Cost, User-owned Security Systems without Monthly Payments =====
 There are very few systems that just require a one-time fee and offer security for free. Systems such as Iris [5] offer a free monthly service, but it is very limited, restricting the security system to only email or text one individual, and restricting mobile access. This is where the remote security system project comes in, putting complete control of security in the customer’s hands and eliminating recurring costs completely.
 === Project Application and Impact ===
 The wireless remote security system is designed to be a user-installed and user-owned system without a recurring monthly fee. A homeowner or small business owner can purchase the system, install it themselves, and have security in a particular home or business for the life of the hardware. This is accomplished by eliminating the call center, and directly contacting the user with intrusion alerts from the base station through email or text. Whether or not the wireless remote security system is marketed or not, the end product will be a working prototype of a security system that is expandable.
-==== Impact on Traditional Security System Market ====
+===== Impact on Traditional Security System Market =====
 Traditional security system owners will only be interested in a cheap security system if they are completely convinced that it will be as reliable as a traditional system. The goal of the project is to make the prototype security system very reliable, although many bigger businesses already have preexisting agreements with security companies and aren’t very willing to try newer, cheaper products. However, small businesses and homeowners which want to save money from their traditional security systems should be interested in this project’s low-cost alternative.
-==== Impact on Emerging Low-Cost Security Systems ====
+===== Impact on Emerging Low-Cost Security Systems =====
 Users of new and emerging products such as SimpliSafe are already willing to try alternatives to traditional security systems, and will likely be interested in a similar security system, but without the recurring payments.
-==== Establishing a New Security System Market without Recurring Fees ====
+===== Establishing a New Security System Market without Recurring Fees =====
 There are users that may not even have the money for the cheaper emerging security systems. Monthly costs may scare away many customers, so a product with no monthly fees creates a new market of customers who want to make a onetime payment for a security system. This project will establish a market of its own: homeowners and small businesses that are unable to unwilling to pay monthly fees.

 == Abstract ==
 Traditional security systems are expensive, requiring a costly installation and an exorbitant monthly fee. These costs can be prohibitive to both small business owners and homeowners, who both have limited resources to dedicate to a security system. By replacing wired sensors with user-installable wireless sensors, the cost of a professional installation can be eliminated. By substituting a call center with text alerts, a user-accessible web server, and an Android application, monthly fees can be eliminated and security can be placed into the property owner’s hands. The system will be comprised of a wireless base station, low-power wireless motion and door sensors, and a web and Android application. The base station will receive wireless transmissions from the sensors and notify the user of activity via a text alert. The user will also be able to use a web or Android application to view security reports remotely. The result of this project will be a working prototype of this wireless security system that is expandable.
