Lightning is a powerful and unpredictable force of nature. A single strike can damage property, cause dangerous electrical surges and threaten personal safety. That’s why investing in a dedicated home lightning detector is essential for proactive protection of your home and loved ones.

What is a Home Lightning Detector?
A home lightning detector is a specialised sensor system that monitors atmospheric electric activity – handling both local disturbances and distant lightning risk. Unlike weather forecasts or simply detecting flashes, this technology:
- Warns of potential lightning before the first strike (through electric field and charged precipitation sensing)
- Detects all lightning types – cloud-to-ground, intra-cloud and cloud-to-cloud
- Minimises false alarms using robust, quasi‑electrostatic detection methods
Such systems are uniquely suited for home or small‑site installation, offering advanced warning and peace of mind.

How It Works
- The BTD‑200 sensor continuously monitors local electric field strength and charged precipitation.
- As the electrical environment changes – indicators of a forming thunderstorm – it issues an alert up to 20 minutes before the first lightning strike.
- The indoor Lightning Works software displays status, warning zones and can trigger alarms or remote notifications.
- Once the storm threat passes, the alert resets automatically, allowing normal activity to resume safely.
Installation Tips
- Place outdoors, ideally clear of obstructions, elevated (e.g. roof or mast).
- Ensure reliable power and PC connection for the Lightning Works software.
- Optionally incorporate SMS/email alerts via Lightning Works Messenger integration.
- Conduct routine self‑tests and check health status through the software dashboard.
