Devices

The hardware behind your alerts

We choose, test and configure every device ourselves, then deliver it anywhere in Sri Lanka ready to use. Each one is tested in Sri Lankan heat, rain and coastal air. All of them send their alerts to the same place: WhatsApp.

Every device is watched, too

Our room and door units send a health check every 2 minutes. If a device goes silent for more than 6 minutes, because of a power cut, a Wi-Fi outage or tampering, it is marked offline and you get an alert. The dashboard shows each device's uptime, outages and battery history for the last 7 days.

All devices are configured and supported by LankaTrack, and come with an installation guide. Specifications may change as we upgrade our hardware.
