Ubiquiti UniFi AI Multi Sensor 2 - Smart Security Multi-Sensor, White

Keeping an eye on every corner of your property can be a challenge, especially when you need to monitor more than just video. The Ubiquiti UniFi AI Multi Sensor 2 consolidates motion, temperature, humidity, air quality, sound, and tamper detection into a single compact device, giving you a comprehensive view of your environment without a tangle of separate sensors.

Who is it for

This multi-sensor is ideal for homeowners, IT administrators, and business owners who already use UniFi Protect and want to extend their security and environmental monitoring beyond traditional cameras. It is perfect for server rooms, warehouses, offices, or any space where conditions matter as much as intrusion detection.

Main features

• Detects motion with a PIR sensor up to 5 meters (16 feet) away, triggering alerts or automations.
• Monitors ambient temperature and humidity to help prevent equipment overheating or mold growth.
• Measures air quality by detecting volatile organic compounds (VOCs), alerting you to poor ventilation or chemical leaks.
• Listens for specific sounds like smoke or CO alarms, adding an extra layer of safety.
• Includes an accelerometer-based tamper sensor that alerts you if someone tries to move or disable the device.
• Connects via Wi-Fi 802.11a/b/g/n/ac (2.4/5 GHz) or Bluetooth 5.0 for flexible placement.
• Powered by USB-C (5V, 2A) or PoE with an optional adapter, so you can choose the most convenient power source.
• Features a built-in microphone and speaker for two-way audio and audible alerts.
• Designed for wall, ceiling, or desk mounting with a white polycarbonate enclosure that blends into any decor.
• Fully integrated with UniFi Protect (version 2.2.7 or later) for centralized management and notifications.

Tips

Place the sensor in a central location away from direct sunlight or heating vents for accurate temperature and humidity readings. For water leak detection, purchase the optional water leak cable and position it near potential sources like water heaters or under sinks. Use the UniFi Protect app to customize alerts for each sensor type, so you only get notified about what matters most to you.
