SecureLink – Smart Home Security System

SecureLink is a C++ and Qt-based smart home security system. It provides a graphical user interface to monitor and control simulated smart devices like door locks, garage, lights, and cameras. The app connects to a server using TCP sockets, handles user login, transfers log files, and displays motion alerts in real-time.
