The Atlona AT-OCS-900N is a network-enabled multi-function sensor designed for use in a wide variety of AV automation applications. This ceiling mounted sensor uses passive infrared (PIR) technology to detect occupancy in the coverage area. The OCS-900N utilizes an IP network to communicate with select Atlona products or our Velocity system to automatically control AV components based on whether the space is occupied. It comes with two lenses that cover up to 900 or 2,000 square feet depending on ceiling height. A blinder insert is included that limits the sensor’s field of view, preventing detection in unwanted areas such as doorways or windows with heavy cross traffic. Installation is simplified by Power over Ethernet (PoE), that provides both communications and power over a single cable as well as spring-loaded clamps that secure the sensor to a ceiling tile.

In addition to occupancy, the OCS-900N also captures temperature and ambient light level information. Its open standard design allows sensor information to be communicated to third-party ventilation, lighting, and other systems over TCP/IP using common protocols such as UDP, TCP, WebSocket, and MQTT.
The AT-OCS-900N works directly with the AT-WAVE-101 or Velocity™ to automatically control AV system startup or shutdown based on occupancy.
In addition to occupancy, the OCS-900N also captures temperature and ambient light levels, and allows the information to be communicated to Atlona and third-party systems over the network using common protocols including UDP, TCP, WebSocket, and MQTT.
Includes two lenses that cover 900 or 2,000 square feet depending on ceiling height and a blinder insert to help prevent unwanted detection from cross traffic. Configurable LED’s to differentiate it from other equipment in the ceiling. Single PoE connection provides both communication and power. Self-contained spring-loaded clamps secure the sensor to a ceiling tile.
