A fixed safety station for sites with no mobile coverage, no grid power and few maintenance visits. It is designed for a real winter, with the aim that it is still working on the day somebody needs it.
Safety networks · Campuses, remote sites and open water
The first minute counts.
In an emergency in a school, at a remote site, or in the water past the flags, what matters is getting a signal out to somebody who can act — and having the equipment still work on the day it is needed.

The problem
Buildings are good at stopping signals.
Many school buildings are steel and concrete, with poor interior coverage, a network built for classroom traffic, and a safety system that has to work on a day nobody rehearsed for. A remote site may have no coverage at all, no grid power, and winters that are hard on electronics.
Both are the same design brief written twice: get a signal out of a hard place, and design the equipment to stay dependable for years.
These systems are in development and none is offered for sale. The material below says what each is for and where it stands, not how it is built.
Campuses and remote sites
A fixed emergency alert for a building during an active incident, with K-12 schools as the main use. It is meant to let responders and others arriving at a school know that an incident is under way.
Light that helps people in a corridor see which way to move, without an announcement anyone has to hear or understand.
School funding
Public programs have funded school safety work.
Programs that have funded school safety work include the U.S. Department of Justice COPS Office School Violence Prevention Program, the Bureau of Justice Assistance STOP School Violence program and Georgia’s school safety grants. E-Rate may apply to the network side of a project where that part qualifies.
Each has its own rules, set by the agency that runs it. Katachi makes no claim about eligibility, amounts, dates or the outcome of any application, and none of these programs is tied to anything Katachi is developing.
Open water
The hard part starts where the guarding stops.
Much of the water people swim in has no lifeguard. Inside a guarded zone, a trained person is keeping an eye on the water. The design problem starts at the edge of that zone, where nobody is looking and nobody is counting, and word of trouble can arrive late.
A lifeguard tower covers a limited stretch of beach. Beyond the flags and below the surface, phones and everyday communications become unreliable. The shoreline keeps going, and so do the people.
Our brief is a system that is meant to support the guarded beach and to be useful beyond it: equipment carried by people in the water, equipment along the beach, and a view for the person running the shift. It also means designing for salt, sand, sun and a season that runs from a slow weekday to a holiday weekend.
The open-water system
Three parts, designed to work together.
Devices carried by the people already in the water — beginning with guards, and extending to swimmers and surfers who want them. Designed for someone with cold hands, no phone, and no time to read anything.
Equipment along the shore that extends coverage past the tower and gives a reported incident a position rather than a description. It is designed to be handled by the crew already on the beach.
A shore-side view of the equipment in use for the person running the shift, and a record afterwards for the people who have to report it. Designed to hand an incident off cleanly to the agencies that respond on the water.
What this is, and is not
It is designed to help locate and reach people who carry the equipment, and to support the judgment of the guards on duty. It does not replace lifeguards, it does not recognize trouble on its own, and it cannot find anyone who is not carrying the equipment.
Where this stands
Engineering is active. Nothing is offered for sale, and construction detail is not published.
If you run a school district’s safety program, a beach, a county water safety program, or a lifeguard service, we would like to hear from you.
