Problem Statement
Almost all home security systems available to consumers require monitoring by an outside party such as ADT and ESCO; these outside parties usually charge an installation fee and a recurring monthly fee.
Our design called The Smart Security System (SSS) will allow home and business owners to monitor their homes and businesses via their smart phones.
Activating and deactivating the sensors will be done via their smart phone wirelessly using Wi-Fi technology. This allows them to have control of the system regardless of where they are.
Our system will include a motion sensor, gas/smoke detector, temperature sensor, and a built in camera.

Engineering requirements
Low power consumption, maximum voltage 5 VDC at 300mA. Dimensions of system: 6’’H * 7’’W * 2’’D. Device has to be controlled wirelessly via Bluetooth or Wi-Fi. Visual images will be in Joint Photographic Experts Group (JPEG) format. At
least 2 Mega pixels. Device must detect common gasses (LPG (Propane/Butane), methane,
hydrogen, smoke and alcohol) at concentrations of 300ppm to 5000ppm. Detect levels of infrared radiation at a range of 110 degrees (front view),
70 degrees (side view) for up to 15ft. +/- 1ft. Temperature sensor must have an operating range of 35 to 120 degrees
Fahrenheit with accuracy of +/- 2 degrees Fahrenheit. Humidity range of 25 to 90% with accuracy of +/- 5% RH for the humidity.
