Verkada | QT11-W Wireless Universal Transmitter Sensor

Verkada QT11-W Wireless Universal Transmitter Sensor

Cloud-managed wireless universal transmitter that brings compatible third-party wired sensors into Verkada New Alarms through VLink wireless communication.

The Verkada QT11-W Wireless Universal Transmitter Sensor is designed to help organizations connect compatible third-party two-wire sensors to a Verkada New Alarms deployment without running new wire back to the alarm panel. Instead of replacing every existing wired sensor, the QT11-W can convert a supported wired sensor into a wireless device that communicates through Verkada’s VLink wireless ecosystem.

This makes the QT11-W especially useful for retrofit alarm projects, mixed sensor environments, and locations where a wired sensor is already installed but cabling back to the panel is difficult, expensive, or impractical. Verkada describes the QT11 as a universal transmitter that allows customers to turn third-party two-wire sensors into wireless sensors and supports supervised wiring to help detect wire tampering.

Key Features

• Wireless Universal Transmitter: Converts compatible third-party two-wire sensors into wireless alarm sensors for Verkada New Alarms.
• Supervised Wiring Support: Helps detect wire tampering or wiring issues through supervised input wiring.
• One Wired Alarm Input: Includes one alarm input compatible with variable end-of-line resistors from 1kΩ to 4.7kΩ.
• Long Wireless Range: Supports up to 2,000 ft / 600 m open-field line-of-sight range when paired with a compatible Verkada VLink hub.
• Up to 10-Year Battery Life: Runs on two included Energizer Ultimate Lithium L91 AA batteries with up to 10 years of typical battery life.
• VLink Wireless Communication: Uses Verkada’s sub-GHz VLink wireless network for New Alarms sensor connectivity.
• Flexible Retrofit Use: Useful for incorporating existing wired contacts or third-party two-wire sensors into a wireless-first Verkada alarm design.
• Tamper Detection: Includes tamper detection with breakaway tab support.
• Cloud-Managed in Command: Sensor activity, device status, alarm events, and video context can be managed through Verkada Command.
• New Alarms Compatibility: Compatible with Verkada New Alarms VLink hubs and not intended for Classic Alarms hub variants.

Built for Retrofit Alarm Projects

The QT11-W is a practical tool for projects where existing wired sensors are still useful, but the customer wants to modernize the alarm system around Verkada New Alarms. In many buildings, door contacts, specialty contacts, or other two-wire sensors may already be installed in useful locations. The QT11-W allows those compatible sensors to be brought into the Verkada ecosystem wirelessly, reducing the need to pull new cable back to a panel.

That makes it a good fit for offices, schools, healthcare facilities, retail stores, warehouses, utility spaces, and multi-site businesses where existing alarm infrastructure can still provide value.

Supervised Input for Better Alarm Integrity

The QT11-W supports supervised wiring, which helps the system detect tampering or wiring faults instead of simply treating the connected sensor as an open or closed contact. This is especially valuable in security environments where the condition of the wire matters as much as the state of the sensor. Support for variable end-of-line resistors from 1kΩ to 4.7kΩ gives installers flexibility when working with compatible two-wire sensor configurations.

Cloud-Managed Through Verkada Command

As part of Verkada New Alarms, the QT11-W can be monitored and managed through Verkada Command. Teams can review sensor activity, investigate alarm events, check device health, and pair alarm activity with video context from Verkada or compatible third-party cameras. Verkada’s Q Series is designed for cloud-managed wireless alarm deployments with easier installation, servicing, and reliable performance.
