Types of SuperLink Sensors

UniFi’s Protect Sensor Family consists of multiple sensor types, each designed for specific security, automation, or environmental monitoring purposes.

Glass Break Sensor

The Glass Break Sensor detects the unique acoustic signature of breaking glass, identifying forced entry attempts or accidental damage. Unlike traditional motion-based security systems, this sensor provides an added layer of perimeter protection for homes, offices, and retail spaces.

According to ADT Smart Security, acoustic-based glass break detection is a critical feature in modern intrusion prevention systems, offering faster response times compared to motion-based security alone.

Siren

The Siren emits audible alerts when triggered by security threats or emergency conditions. It can be integrated into custom automation workflows, allowing businesses and homeowners to activate deterrents for break-ins, environmental hazards, or unauthorized access.

As noted in NIST’s Cyber-Physical Security Guidelines, audio-based alerts are an essential component of layered security strategies, ensuring quick response to potential threats.

Environment Sensor

The Environment Sensor monitors temperature, humidity, and water leaks, providing early warnings for potential property damage. This is especially valuable for server rooms, basements, and climate-sensitive storage areas, where environmental conditions must be carefully regulated.

Studies from The U.S. Environmental Protection Agency (EPA) highlight that excessive humidity and temperature fluctuations are a leading cause of equipment failure in IT environments, making smart environmental monitoring essential for businesses.

Relay

The Relay acts as a control interface for external devices, allowing users to activate automation triggers such as turning on lights, locking/unlocking doors, or controlling ventilation systems.

Relay-controlled automation is widely used in industrial IoT applications, where remote control and process automation increase operational efficiency and security resilience.

Entry Sensor

The Entry Sensor detects when doors or windows are opened or closed, helping businesses and homeowners monitor access points and unauthorized entry attempts.

Reports from Cybersecurity & Infrastructure Security Agency (CISA) emphasize that entry sensors play a key role in access control, providing real-time insights into physical security vulnerabilities.

Alarm Hub

The Alarm Hub serves as the centralized control point for managing security alerts and automation rules. It integrates multiple Protect Sensors into a unified response system, ensuring coordinated action when threats are detected.

A study from SANS Institute found that centralized security response systems significantly reduce reaction times to security threats, making automation hubs a critical element in modern security infrastructures.

Air Quality Sensor

The Air Quality Sensor measures indoor air conditions, monitoring particulate matter, CO2 levels, and volatile organic compounds (VOCs).
