RailCam By: Chris Perilla, Enrique Hernandez, Dale Mahabir, and Youssef Faltone. 1
Introduction ● People find great comfort in having a security system for their home or business to keep them altered of intrusion. Our product is not like other security systems, it has two major features that separates it from the rest: ○ A rail system with an inductive charging station for one camera to be able to monitor a large area. ○ WiFi communication that allows our camera to send captured images to the end users e-mail allowing for instant and informative intrusion notification. Our project consists of an indoor or outdoor PTZ (Pan Tilt Zoom) night vision capable security camera that ● travels horizontally using a simple rail system alongside an indoor or outdoor wall. It will also store images taken by the camera onto an SD card and transmit the images via WiFi to the end user's email. The system will have a backup 5 V battery, that will be charged wirelessly using inductive charging technology. A solar panel will be used as energy source for the camera system during the day. 2

Market Analysis/Regulations ● Industry grew from $11.5 billion in 2008 to $37.7 billion in 2015 and growing. ● In 2013 NewYorkTimes poll showed 78% of respondents supported the use of security cameras in public places. ● Beijiayue, a chinese based company, whose railcam system costs $12,000, our only competitor. ● Our system will be affordable to the everyday business/ residential customer ● Florida Regulations Harvard studies “Summary of statute(s): All parties must consent to the recording or the disclosure of the contents of any wire, oral or electronic communication in Florida. Disclosing communications in violation of the state’s statute is prohibited. Both criminal and civil penalties exist for such infractions. The state’s video voyeurism law bans the secret recording underneath or through the clothing of individuals without their consent, or in areas where they have a reasonable expectation of privacy. - See more at: http://www.rcfp.org/reporters-recording-guide/state-state-guide/florida#sthash.GngGJfFW.dpuf” - State of Florida 3
Top Level Driving Requirements ● Constant 5.1V to avoid data SD card corruption ● Total current draw at least 2000 mAh ● Zilu back up Battery: 5 volt, 4400 mAh ● Motion detection using PIR Sensors and object detection through cam ● OpenCv for object detection ● Inductive charge bases must be 2-3 mm for 500 mAh ● Email notification through Gmail ● Solar cell 9-12V in 5 V out ● Edimax Wifi Dongle to provide internet connection 18.75 Mbytes/s ● Servos with 1.6kgcm torque current weight (279.2 g) ● Rail system 4
Specifications/Power consumption Total power provided P = I*V = (5V)(4.4Ah) = 22Wh Estimated power consumption is 10.4 Wh The above voltage and Amp-Hours are from the data sheet of each component. We will measure these when we start experimenting. 5

WiFi communication from SD ● card to end user’s e-mail (via DropBox/Google Drive). Camera night vision and auto ● focus (already integrated in camera). 9
Technical Trades Power Consumption: A proper UPS to manage between two supplies to reduce probability of SD corruption. Microprocessor: Raspberry PI with possible addition of Arduino to free up processing space. Language: PYTHON and C Battery: The type of battery may change but for now it is the Zilu battery pack. 10

Risk Analysis x1: Complexity of project x2: Coding skills being able to fulfill wireless data transfer task. 15
Risk Mitigation Keep research and work ahead of schedule in order to correct problems ● early on. Research, learn, and sharpen coding skills pertaining to project. ● Complete proper research prior to buying any materials or components ● to lower chances of surpassing budget and buying unnecessary or useless parts. Begin project prototype assembly by Summer and try best to recycle ● parts and components. Research common mistakes/issues made/found in home security ● products to optimize product. 16
Closure Plans BOM is still open and we plan on finalising the components before summer. Learning PYTHON basics is an essential part of our project and needs to be completed by mid summer. More research on components to get best performance for lowest price. Ensure compatibility between all components before summer. 17
