Frequently Asked Questions

Choosing the right detection system is an important decision. Below you will find answers to the most common questions about MethAlarm — from how the device works to deployment, alerts, and data security.

Device & Technology

How sensitive is the device?

It detects airborne meth particles starting at 1 ppm.

Does it record sound or video?

No. The device collects no audio, video, or imagery — only air quality data.

What are the weight and dimensions of the device?

Weight: 258g (330g with batteries). Dimensions: 115mm x 90mm x 60mm (approx. 5.9″ x 3.5″ x 2.5″).

What is the coverage area?

Approximately 7,500 ft³ — about the size of a single-level, 3-bedroom home.

How often does the device take readings?

The test frequency is user-defined — as frequent as every 15 minutes.

What do the LED indicators mean?

Green: Sensor active
Red: Threshold exceeded
Violet: Network connected
White/Cyan: Tilt/tamper notification

Deployment & Use

How long does it take to install the device?

10–15 minutes.

How is the device powered?

Operates with 3 AA alkaline batteries (Energizer Max recommended) or can be connected to AC power.

Can the device be moved?

Yes, but movement triggers tamper/tilt alerts. For best results, one device should be assigned per location.

How do I know when to act?

Review spike trends and average ppm in the dashboard. A spike usually indicates recent use; a sustained baseline increase suggests contamination buildup.

What happens if contamination is detected?

Use surface swabbing to confirm, then consult professional remediation services if needed.

Data & Security

How are alerts delivered?

Alerts are sent instantly by SMS and email. All results are also logged in the secure AWS-hosted cloud portal.

Is the data secure?

Yes. Data is encrypted, stored on AWS servers, and requires a username/password to access.

Can people avoid detection?

No. Tamper and tilt alerts prevent intentional interference or removal.
