Product Introduction
The LifeSmart Defed Siren is an indoor siren from the DEFED security series launched by LifeSmart, a world-leading AIoT brand. It focuses on simple AI linkage via the LifeSmart App (iOS/Android support), allowing it to form a complete smart home security system with door/window sensors, motion sensors, and other devices. Once the system detects an intruder or an unexpected opening of a door or window, the Defed Siren immediately emits a high-intensity alarm sound and sends a real-time notification via the mobile app, helping users stay updated on their home safety status at all times.
Key Features
- 105dB High-Decibel Alarm: The volume and duration can be adjusted via the LifeSmart App. It provides a maximum 105dB high-intensity alarm, which triggers instantly when the Motion Sensor detects an intruder or a door/window is opened.
- Tamper Protection: The Defed Siren can be fixed to a wall using screws or 3M adhesive. If the sensor is forcibly removed from the wall, a tamper protection notification is immediately sent to the user's mobile phone, ensuring safety and reliability.
- CoSS Wireless Connection, Ultra-Long Battery Life: It connects to the Smart Station via CoSS wireless signal with a reception range of up to 800 meters. Featuring extremely low power consumption, it offers up to 5 years of battery life and provides two-way communication with the Smart Station for real-time status feedback.
