Site Survey Tool

MonnitSKU: MNO2-9-W2-SS-ST



The ALTA® Wireless Site Survey Tool helps you plan the placement of ALTA Wireless Sensors by measuring the strength and quality of the radio frequency (RF) signal from an ALTA Gateway.

Features of Monnit ALTA Sensors:

- Wireless range of 2,000+ feet through 18+ walls

- Frequency-Hopping Spread Spectrum (FHSS)

- Best-in-class interference immunity

- Best-in-class power management for longer battery life

- Encrypt-RF ® Security (Diffie-Hellman Key Exchange +Advanced Encryption Standard (AES)-128 Cipher Block Chaining (CBC) for sensor data messages)

- Sensor logs 2000 to 4000 readings if the gateway connection is lost (non-volatile flash, persists through power cycling): - 10-minute Heartbeats = ~ 22 days - 2-hour Heartbeats = ~ 266 days

- Automatic over-the-air updates to sensor firmware (future-proof)

- Free iMonnit Basic Online Wireless Sensor Monitoring and Notification System to configure sensors, view data, and send alerts via SMS text, email, and voice call
