Plus, the app sends timely battery replacement alerts—keeping your home secure without the stress of surprise power loss.
- Built for Security and Durability: The U50 doesn’t just look smart—it’s built tough. Meeting BHMA Level 3 safety standards, it features a strong zinc alloy construction and an IPX5 water-resistance rating. Whether it’s rain, shine, or freezing conditions down to -18°C (-0.4°F), the U50 performs reliably year-round, making it perfect for any environment.
