Tuya WiFi Smart Door & Window Sensor: Real-Time Security with 90dB Siren

Traditional door sensors tell you when someone enters after they are already inside. The MC400S WiFi Door Sensor goes a step further by providing an immediate audible deterrent. Whether it’s your main entrance, a safe, or a shop shutter, this device is your first line of defense.

Dual Protection: Local Alarm + Mobile Alert

Most smart sensors are silent, but the MC400S is equipped with a 90dB alarm sound.

• Instant Deterrence: If a door or window is pried open, the loud siren warns the intruder immediately.

• Global Monitoring: No matter where you are in the world, your smartphone will receive a push notification the second the magnetic contact is broken.

• App History: Keep a detailed record of every “Open” and “Close” event directly in the TuyaSmart or Smart Life app.

Smart Home Integration & Voice Control

As a core part of the Tuya / Smart Life ecosystem, this sensor plays well with others:

• Voice Assistant Compatible: “Alexa, is the front door closed?” or “Hey Google, check the office window.”

• Smart Linkage Control: Create automation scenes. For example, set your Tuya / Smart Life WiFi Switches to turn on the lights automatically when the front door opens at night.

• Low Battery Intelligence: Never worry about a dead sensor. The app provides low-battery detection alerts when the voltage drops below 2.4V.

Easy Installation & Reliable Design

Designed for the modern Bangladeshi home, the MC400S is sleek and unobtrusive:

• No Hub Required: Connects directly to your 2.4GHz WiFi router.

• Tool-Free Setup: Use the included high-quality double-sided tape to mount it on any surface in seconds.

• Wide Compatibility: Works on doors, windows, drawers, cupboards, and safe boxes.
