Don't replace your towers. Bring them back.

Upgrade aging blue light towers, e-phones, and call boxes into modern, connected, fully monitored emergency stations — without trenching, without rip-and-replace, and at a fraction of new-tower cost.

The real cost of waiting.

Replacing a tower can run $50K–$60K all-in.
Retrofitting is a fraction of that.

$20K-25K

Hardware alone for one new tower — before trenching, labor, permits, and downtime push the true cost to $50K–$60K. 

<$5K

 Average all-in retrofit cost per tower, using the housing already in place. 

~60%

 Typical savings versus full replacement across a network.

 30–40 units modernized — minimal disruption to campus or operations. 

A deeper breakdown of deferred-maintenance risk, procurement delays, and replacement math is in our blog, The Real Cost of Outdated Campus Emergency Systems.

Overview

It's time for an upgrade.

Whether your emergency calling equipment has been discontinued, sits dark half the year, or simply can't keep up with what a modern campus expects — the K1 Retrofit Kit modernizes the towers, e-phones, and call boxes you already own.

Every kit installs wireless cellular connectivity, optional solar power and battery backup, two-way emergency intercom, and self-monitoring software — all inside the housing that's already in the ground.

No two restorations are identical. Some towers need only new electronics. Others need refinishing, corrosion removal, or upgraded solar and battery to carry the new system. We assess each site and scope the work to match.

 

Ideally suited for: CASE Emergency Systems, Code Blue, Gaitronics, Talk-a-Phone and others.

More than a repair

Every retrofit is a node, not a dead end.

The retrofit kit isn't a one-off part. It runs the same core intelligence and connectivity that powers the rest of the Knightscope — so a tower you restore today can extend into the Autonomous Security Force of tomorrow, on your timeline. 

 

01 A unified intelligence control module across all Knightscope systems — proven hardware, not a one-off board. 
02 Two-way intercom on every unit — the same voice layer used across the Knightscope ecosystem. 
03 One connected pipeline — your retrofitted network reports into the same monitoring backbone as every other Knightscope device. 
04 Monitored the same way — our analysts watch a retrofitted tower exactly as they watch a robot or a new tower. One network. One standard.

 

Blue Light Tower

 
Trust and reliability, everywhere.

Installing the hardware is step one. Knowing it works is the job.

Every Knightscope unit — retrofitted or new — reports its operational status in real time. The moment a tower needs attention, the right people know. No more walking the campus to test call boxes one by one.

Our Risk and Threat Exposure Analysts (RTX) monitor deployed units around the clock, verifies alerts, and routes service before a small fault becomes an open headline.L
