Our ALERT2 Products


Blue Water Design's ALERT2 products employ rugged designs meant for unattended use in remote locations.


Our ALERT2 encoders allow long distance communincation over VHF radio frequencies, and are designed to be run off a solar panel and a battery.


ALERT2 devices use TDMA (time-division multiple access) and sophisicated error detection and correction algorithms to ensure that messages arrive consistently and are free from errors.


Our ALERT2 devices are meant for remote command and control applications where secure, encrypted, bi-directional communication is required.

About ALERT2

ALERT2 is a low-bandwidth, high-reliability data protocol intended for transmission over VHF/UHF radios. It is an open standard published by the National Hydrologic Warning Council (NWHC), and uses a TDMA, a time-slot scheme, to ensure device transmissions do not occur simultaneously. ALERT2 is often used for the collection of hydrological data, but is flexible enough that it may be used for many applications. If you have remote sites that need reliable communications, ALERT2 may be a good solution for you. Contact Blue Water Design for further information.
