Choose the mounting location based on the space’s layout and the coverage needed: ceiling-mounted sensors provide broad, 360-degree coverage, wall-mounted sensors cover a 180-degree area, corner-mounted sensors suit rooms with a 90-degree viewing angle, and hall-mounted sensors support longer, narrower spaces. Also consider potential obstructions or cross traffic, whether the sensor will control lighting or AV equipment, and whether a wireless or Power over Ethernet connection fits the installation.

Occupancy sensors can send motion or vacancy signals to compatible lighting controls, such as dimmers and switches, to turn lights on or off based on room use, while wireless models communicate through radio frequency and networked models can use Power over Ethernet (PoE) and IP connections. In AV, building automation, and smart home systems, these signals can trigger equipment control, room monitoring, energy-saving actions, and other programmed routines through compatible control platforms, gateways, or protocols such as TCP, UDP, WebSocket, and MQTT.

Wired occupancy sensors connect to a lighting, AV, or automation system through physical cabling, while wireless models typically use batteries and radio or Bluetooth communication for easier placement where new wiring may be difficult. Power over Ethernet (PoE) sensors are a networked wired option that carries power and sensor data over one Ethernet cable, supporting integration with compatible AV or automation systems.

Plan coverage around the room’s layout by choosing a mounting position and field of view that cover occupied areas while limiting sightlines into doorways, windows, hallways, or adjacent spaces. Use corner-, wall-, hall-, or ceiling-mounted sensors as appropriate, and consider models with adjustable or customizable detection areas, such as a field-of-view insert, to help reduce unwanted activity from cross traffic.
