This document presents a proposal for a smart home security system called the Smart Security System (SSS). The SSS aims to provide an affordable home security option that allows users to monitor and control their system remotely via a smartphone app. It includes features like motion detection, gas/smoke detection, temperature monitoring, and a built-in camera. This would provide multiple security features in one device, avoiding extra costs of separate components. The proposal describes the history of home security technology, current industry offerings, and technical research on security systems. It then outlines the project's engineering requirements, functional design, project management plan, proposed budget, and conclusions.
