This document describes a proposed web-based online embedded security system and alertness via social media. The system uses a Raspberry Pi kit with a hidden Markov model algorithm to analyze frames from a web camera monitoring a bank. It detects changes and object movement to identify intruders. If an intruder is detected, alerts are sent via WhatsApp to the bank manager and police for security purposes. The system aims to provide improved bank security over existing CCTV systems by more quickly detecting intruders before they can steal money.
