Utilities need to know what is happening on site before anyone else does. Labor and system security are major industry challenges. Sentry addresses both economically.
John founded Mission Communications, the company that brought cellular and web-based SCADA to remote water and wastewater sites when the idea was still new. He sold his stake in 2010.
He has since written on the history of SCADA in the water sector for Wastewater Digest, and has built four businesses across nearly thirty years in communications and security.
By the time he wrote that history, he had already started building the part he thought was still missing.
What was missing then was affordable and reliable remote site video.
The review screen at the office, and the phone of whoever is on call at 2 a.m.
Event review at the office: the clip, the tags that were true at that moment, and the human form record kept together.

THE CASE
Three questions an alarm leaves open
Is the site in trouble
A level goes high. Nothing in the alarm says whether the pad is flooding or a float stuck.
Is a person there
Human form detection answers it before anyone gets in a truck at 2 a.m.
Does a truck need to roll
Clip, tags and record arrive together, the answer before the drive.
THE COMPLIANCE LAYER
An evidence package, not a stream
Sentry answers with a picture, the SCADA tags and the human form record instead of a full time stream. That file is also the compliance and insurance record. Cyber gets the headlines, but a picture of who opened the door is not a firewall. It is a lock with a log.

The founder still takes the early calls.
John still answers the early calls himself, keeping Sentry practical, focused, and grounded in the realities of municipal wastewater operations.
