This security system combines environmental risk monitoring—such as fire and gas leaks—with anti-intrusion protection to safeguard both lives and property. Sensors on doors, windows, and perimeter areas detect unauthorized entry, while dedicated units monitor smoke and combustible gas levels in real-time; if thresholds are exceeded, the system triggers an immediate local alarm and sends remote notifications. The system can also integrate with smart valves to automatically shut off the gas supply upon detecting a leak, reducing the risk of explosions or gas poisoning. Video equipment records the scene during an incident, facilitating post-event review. The system supports tiered alerts, distinguishing between early warnings and critical emergencies. Devices perform regular self-checks and proactively notify users if maintenance is required. Suitable for various types of residences, this solution addresses both security threats and common household environmental hazards, covering two core categories of home risk with a single system.
