*Sentry is designed for direct detection of smoke within the monitored space.

This is a small and sleek security device that allows you to control the decibel settings for noise alerts 🔊

It does need power and wifi to work. We stashed it away in a discreet spot on top of the refrigerator 🫣

What types of smoke does Sentry detect?

Sentry detects cigarette, marijuana, cigar, and vape.

Note: Sentry alerts do not specify which type of recreational smoke is occurring. It tells you if someone is smoking recreationally and time stamps the incident to provide proof.

How is this different from a normal smoke detector?

A normal smoke detector can’t tell the difference between cooking/candle smoke verses recreational smoke such as cigarette, cigar, marijuana, and vaping. Sentry will give you an alert and a report when someone smokes in your property, so you can ask them to stop and/or file a claim.

Note: Sentry is not intended to replace your traditional smoke detector.

Can the device listen to my conversations?

Sentry protects yours and your guests' privacy and cannot listen to your conversations. Sentry only measures noise levels and it does not store any sound data or transmit sound data to the cloud.

Who gets notified when guests are too loud?

Whoever installs the Sentry mobile app and enables sentry on their account. You can enable notifications for App notifications, SMS notifications, and/or email notifications.

How many do I need for my property?

Generally, one Sentry per contiguous indoor space you'd like to monitor. Sentry can detect smoke ~30ft away within minutes of the incident happening.

How sensitive are the smoke sensors?

Can they detect smoke from neighbors, on guests clothes that come onto the property, or if someone smokes out of a window while inside?

Sentry is designed for direct detection of recreational smoke within the monitored space.

How much space will the tamper device covering take up over the plug & outlet?

It will only cover the one outlet where the Sentry is plugged in. It will not cover/interfere with the second outlet in a double outlet socket.

Why is there one subscription per a Sentry device?

The subscription charge is for monitoring, app development and constant improvements. Each device monitors a space where it is placed, independent of others either in the same or another property. Each device requires a subscription.
