Wireless Motion Detection Sensor
The ALTA wireless motion detection sensor uses an infrared sensor to accurately detect movements made by people/animals within 15 ft (4.5 m) range
Principle of Operation
The Wireless Motion Detection Sensor detects motion and movement using infrared technology. When the sensor detects movement it communicates with the iMonnit Online Sensor Monitoring and Notification System. iMonnit stores all data in the online system where the data can be reviewed and exported as a data sheet or graph. Notifications can be set up through the online system to alert the user when motion has been detected.
• Software adjustable range (15 ft/12 ft/9 ft)
Features of Monnit ALTA Sensors
• Wireless range of 1,200+ feet through 12+ walls *
• Frequency-Hopping Spread Spectrum (FHSS)
• Improved interference immunity • Improved power management for longer battery life ** (12+ years on AA batteries)
• Encrypt-RF® Security (Diffie-Hellman Key Exchange+AES-128 CBC for sensor data messages)
• Onboard data memory stores up to 512 readings per sensor:
-10-minute heartbeats = 3.5 days
-2-hour heartbeats = 42 days
• Over-the-air updates (future proof)
• Free iMonnit basic online wireless sensor monitoring and notification system to configure sensors, view data and set alerts via SMS text and email
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables. Other power options are also available.
