CRESTRON CEN-ODT-C-POE Crestron motion detector Passive infrared (PIR)/ultrasonic sensor

The Crestron® CEN-ODT-C-POE is a low-profile, ceiling-mounted occupancy sensor that features passive infrared (PIR) and ultrasonic (US) motion detection technology.

The CEN-ODT-C-POE is designed for areas up to 2,000 square feet, making it great for use in large spaces such as auditoriums, warehouses, and building lobbies. It is an effective solution for reducing energy consumption and enhancing the functionality of lighting and environmental systems.

A single-wire Ethernet connection allows the CEN-ODT-C-POE to report to the Crestron XiO Cloud™ service when no control system is in place. Crestron XiO Cloud integration allows for device configuration, occupancy status reporting, and online/offline status.

Dual-Technology Occupancy Sensing
Achieving consistent and dependable occupancy sensing is accomplished using a combination of ultrasonic (US) and passive infrared (PIR) sensing technologies. Ultrasonic motion detection is highly sensitive to small movements over a large area, while passive infrared sensing ensures superior immunity to false triggers from vibrations, inanimate objects, or movement in an adjacent corridor.

Ultrasonic motion detection can be turned on for Side A, Side B, or both sides of the occupancy sensor to avoid false occupancy readings when the sensor is facing a hallway or doorway. The CEN-ODT-C-POE provides independent sensitivity adjustment for each sensor type for optimum performance in any space.

Crestron XiO Cloud™ Service
The CEN-ODT-C-POE is compatible with the Crestron XiO Cloud™ service, which is an IoT (Internet of Things) based platform for remotely provisioning, monitoring, and managing Crestron devices across an enterprise or an entire client base. Built on the Microsoft® Azure® software platform and utilizing Microsoft's industry leading Azure IoT Hub technology, Crestron XiO Cloud enables installers and IT managers to deploy and manage thousands of devices in the time it previously took to manage just one. Unlike other virtual machine based cloud solutions, Azure services provide unlimited scalability to suit the ever growing needs of an enterprise. For more information, visit

Enterprise-Grade Security
Crestron employs enterprise-grade networking with robust security features such as 802.1X authentication, TLS encryption, HTTPS connectivity, and Active Directory® service integration. These features are imperative to protect your network against service interruptions and malicious intrusions, and to ensure compliance with your organization’s network policies. Cloud-based provisioning and management streamlines the process of configuring, monitoring, and updating every device on the network.

Walk-Through Mode
Walk-through mode prevents the lights from remaining on for a long period when someone quickly enters and then leaves a room. The sensor enters walk-through mode when it detects occupancy for less than 90 seconds. When walk-through mode is activated, the sensor indicates that the room is vacant after 60 seconds.

Grace Occupancy Feature
When the lights turn off in a room programmed to vacancy only mode, a 15-second grace period starts during which the room lights can be turned on again by simply waving a hand to trigger the sensor.

Versatile Installation
The CEN-ODT-C-POE achieves a discreet, nearly hidden appearance when installed on a typical drywall or droptile ceiling. Hardware is included for fast and simple mounting in a standard 4-in. octagon box or in a hole created with the help of the provided cutout template.

Power over Ethernet
Using PoE technology (802.3af), the CEN-ODT-C-POE gets its operating power through the LAN wiring from a PoE power source (PWE-4803RU, CEN-SW-POE-5, or CEN-SWPOE-16, all sold separately).
