Motion and Occupancy Sensors

Sense who’s coming or going.

Monnit ALTA® Wireless and Power over Ethernet (PoE) Sensors detect motion via passive infrared (PIR) technology to augment facility security, protect inventory, or optimize building services through use, access, and occupancy data. A wide-angle option is also available for facility managers wishing to audit the occupancy of desks, conference room tables, or hallways as part of a building use evaluation.

Plus, our three-in-one ALTA Wireless Motion+ Sensor can monitor movement, ambient temperature, and relative humidity (RH) in various facilities, including offices, warehouses, factories, data centers, hospitals, labs, kennels, greenhouses, and more.

Detect & Protect

Install and monitor within 15 minutes with these turnkey sensors that alert you via text, email, or call if people or animals move within a range of up to 4.5 meters or 15 feet. Know instantly if a sensitive or restricted area is accessed, if assets or animals are in safe climate conditions, or analyze traffic data to economize HVAC use and enhance sanitation.

These motion detection devices are available in compact coin cell (CC) battery, enterprise AA, Wi-Fi, or PoE models. The ALTA Standard Motion Sensors feature a software-adjustable motion range of 9’, 12’, or 15’ and an 80° viewing angle, making them ideal for general motion detection. The ALTA Wide-Angle Motion Sensor features less range but a 110° viewing angle.

Two AA batteries power the ALTA Wireless Motion+ Sensor. It detects movement within an 80° viewing angle, temperature between -40°F to 257°F (-40°C to 125°C), and 0–100% RH. No Monnit ALTA PIR Motion Detection Sensor uses cameras—the sensors only record heat signals.
