Crestron CEN-ODT-C-POE – Dual-Technology PoE Ceiling Occupancy Sensor

Product Overview

The Crestron CEN-ODT-C-POE is a dual-technology ceiling-mount occupancy sensor powered by Power over Ethernet (PoE), combining passive infrared (PIR) motion detection with ultrasonic occupancy detection to provide reliable room occupancy data for Crestron-controlled commercial AV, lighting, HVAC, and building automation systems. Designed for open-plan offices, conference rooms, classrooms, and commercial spaces where single-technology sensors produce false vacancies or false occupancies, the dual-technology approach ensures accurate occupancy state detection even when occupants are stationary. It communicates occupancy status to Crestron 4-Series control processors via PoE Ethernet, integrating directly into room automation programs without separate sensor power infrastructure.

Product Description

Single-technology occupancy sensors are a documented source of false vacancy events in commercial AV and lighting automation installations: PIR-only sensors miss stationary occupants, while ultrasonic-only sensors can trigger on air movement rather than actual presence. The CEN-ODT-C-POE eliminates these failure modes by requiring both PIR and ultrasonic detection to agree on a vacancy state before outputting a vacant signal — preventing lights and displays from powering off while a meeting room is occupied. PoE powering eliminates the need for separate low-voltage sensor power wiring by delivering both data and power over a single structured Cat5e or Cat6 cable, reducing installation complexity and cost in commercial spaces where PoE network infrastructure is already deployed for Crestron AV devices. Ceiling mount form factor and adjustable sensitivity accommodate the range of commercial ceiling heights and room sizes common in corporate office, conference room, and classroom deployments. The sensor’s occupancy state is reported to the Crestron 4-Series control processor via standard Ethernet, where it can trigger automated AV system power on/off, HVAC setpoint changes, lighting scene recall, and occupancy logging for space utilization analytics. For building managers deploying Crestron room scheduling and resource tracking, the CEN-ODT-C-POE provides the reliable occupancy ground truth that scheduling panel data alone cannot deliver. Refer to the Crestron data sheet for full specifications including detection range, coverage pattern, PoE classification, and environmental ratings.

Key Features

• Dual-Technology PIR + Ultrasonic Detection: Combines passive infrared and ultrasonic sensing — both technologies must confirm vacancy before a vacant state is reported, eliminating the false vacancy events that cause lights and AV systems to power off in occupied rooms.
• PoE Powered — No Separate Power Wiring: IEEE 802.3af or 802.3at PoE delivers both data and power over a single Cat5e/Cat6 cable — eliminates dedicated sensor power infrastructure in commercial spaces with existing PoE network switches.
• Crestron 4-Series Native Integration: Communicates occupancy state to Crestron 4-Series control processors via Ethernet for automated AV, lighting, and HVAC control without third-party middleware or sensor hubs.
• Ceiling-Mount Form Factor: Flush ceiling installation provides wide-area occupancy detection coverage appropriate for conference rooms, open-plan offices, and classrooms of varying sizes. Refer to Crestron data sheet for coverage pattern and range specifications.
• Space Utilization Analytics Support: Occupancy state data logged through the Crestron control system supports space utilization reporting for facilities management, real estate optimization, and corporate workplace analytics programs.
• Adjustable Sensitivity: Detection sensitivity can be tuned to minimize false triggers from adjacent-space activity or HVAC air movement, improving occupancy accuracy in open-plan and lightweight partition environments. Refer to Crestron data sheet for adjustment specifications.

Typical Applications

• Conference rooms with Crestron AV automation requiring reliable occupancy detection for automated display power-off and AV system sleep
• Open-plan offices with stationary workers where PIR-only sensors produce frequent false vacancies and occupants must repeatedly trigger lights to stay on
• University classrooms and training rooms with mixed active and stationary occupancy patterns during lectures and individual study periods
• Government and corporate meeting rooms where occupancy data feeds room scheduling panels and space utilization reporting
• Private offices and focus rooms with automated lighting and HVAC setback requiring confirmed occupancy before energy-saving modes activate
• Huddle rooms and collaboration spaces in commercial office buildings with Crestron-integrated lighting and AV automation
• Healthcare conference rooms and administrative spaces with energy management programs requiring dual-verification occupancy sensing
• Hotel meeting rooms and event spaces with automated AV and lighting control triggered by confirmed room occupancy

Frequently Asked Questions

How does the dual-technology approach prevent false vacancies?
The sensor requires both PIR and ultrasonic detection to agree on a vacancy state before sending the vacant signal to the control system. PIR detects infrared heat movement, while ultrasonic detects subtle physical movement (breathing, micro-movements). A stationary occupant who is invisible to PIR will still be detected by ultrasonic, so the sensor correctly reports occupied. Contact Creation Networks for sensitivity configuration guidance.

What Crestron control hardware does the CEN-ODT-C-POE integrate with?
The CEN-ODT-C-POE communicates occupancy state to Crestron 4-Series control processors via Ethernet. Compatible processors include the CP4, CP4N, MC4, and RMC4. The sensor status is programmed in Crestron SIMPL or SIMPL# to trigger AV, lighting, and HVAC automation actions. Contact Creation Networks for programming and commissioning support.

What PoE switch classification is required?
The CEN-ODT-C-POE is powered via IEEE 802.3af or 802.3at PoE. Most commercial managed network switches with PoE capability will support this sensor. Refer to the Crestron data sheet for the specific PoE power class consumed by this device to confirm switch port budget requirements.

Can the sensor’s detection range be adjusted for different room sizes?
The CEN-ODT-C-POE includes adjustable sensitivity settings to tune detection for different room sizes and ceiling heights. Specific adjustment procedures and sensitivity ranges are documented in the Crestron data sheet and product guide. Contact Creation Networks for commissioning guidance.

Is the CEN-ODT-C-POE compatible with Crestron room scheduling and XiO Cloud?
Occupancy data from the sensor is reported to the Crestron control processor, which can relay it to connected systems including Crestron room scheduling and space analytics platforms. XiO Cloud manages the sensor device itself for enterprise monitoring. Verify specific integration capabilities with current Crestron product documentation or contact Creation Networks.

What is the warranty on the Crestron CEN-ODT-C-POE?
Crestron provides a standard 3-year limited warranty. Contact Creation Networks for warranty service details and support options.
