privacy - yes!

The MultiSensor uses a secure cellular connection and encryption to secure your data. It does not include a microphone or camera so your privacy is further protected.

backing up another monitoring system

The MC4000 can be a primary monitoring device and can also help you to monitor devices that rely on AC power, a fixed broadband connection, and/or a phone line. Because the MultiSensor works for 40+ hours without AC power and uses cellular service, MultiSensor alerts and condition reports are sent when other systems are disabled.

cell service

The MultiSensor uses a leading cellular data service, and works no matter whether you use AT&T, Verizon, T-Mobile, or some other cellular service on your smartphone. Signing up for the low-cost MultiSensor service is easy using the MultiSensor smartphone app or a Web browser.
