Bosch Smart Home Twinguard Smoke Detector with Air Quality Measurement and App Function, Compatible with Apple HomeKit

Twinguard With the Twingard from Bosch Smart Home, false alarms can be avoided: The device is able to distinguish between harmless candle smoke and a real fire hazard. In the event of smoke, the unique Dual Ray technology triggers a low-noise prealarm before the main fire alarm is activated. In addition to its function as a smoke detector, the Twinguard continuously serves as an air quality monitor and measures room temperature and relative humidity to ensure healthy indoor air. The data can be stored for up to three months. In case of bad room air, the user is informed via the app Bosch Smart Home with a push message. Thanks to pre-defined sensitivity values, false smoke alarms such as during cooking in the kitchen can be avoided. The Twinguard can be networked with other Twinguard smart smoke detectors. It is also integrated into the Bosch Smart Home System and, together with the Smart Home cameras, provides reliable all-round protection in the event of fire or burglary. In the event of fire, the Twinguard activates not only all other integrated smart smoke detectors but also the cameras networked in the system, so that the fastest possible response can be made from anywhere at any time - even when no one is at home.
