Overview: ABB-secure@home is a wireless security system designed by ABB to provide maximum protection for people and buildings. It detects dangers such as intrusions, water leaks, and fires, using a wireless communication system based on radio frequency signals.

Specifications: The system operates at 868.3MHz, a less crowded frequency band regulated by European norms, with a power of 25mW. It complies with European standards EN50131 Grade 2 and ETSI-RED (Radio Equipment Directive) 2014/53/EU.

Reliability: The system uses an ABB proprietary communication protocol optimized for long-range wireless communication, supporting distances up to 300m in open fields. Bidirectional transmission allows the central unit to monitor the status of each component.

Security: Communication is digitally encrypted with 128-bit encryption and a 65k rolling code remote control to prevent code replication. The system uses CSMA transmission to avoid interferences and signal collisions.

Features: Key features include bidirectional communication, simplified commissioning, long-distance capability, and robust encryption protocols.

Comparison with ABB-free@home: ABB-free@home focuses on home automation and operates on a 2.4 GHz frequency with a meshed network to mitigate interference. In contrast, ABB-secure@home prioritizes security with a lower frequency band for better signal propagation and data protection.

Conclusion: ABB-secure@home is designed to be secure and reliable, avoiding interference and fraudulent communication while monitoring system status to ensure proper functioning.
