Industrial IoT Coverage Beats Sensor Richness — FourJaw Proves It.
FourJaw started with the classic approach: pull rich data straight from CNC controllers. It worked on the first few machines. Then every new site became its own integration project.
Customers mainly wanted one answer: is this machine making us money?
So FourJaw switched to a simple external power sensor that clips onto any machine’s cable. Lower resolution, but it works on decades-old equipment and unfamiliar brands. They pair it with an operator tablet for reason codes.
The next bottleneck was the network. Customer Wi-Fi and security policies killed more rollouts than the sensor itself. The fix was shipping cellular routers that never touch the corporate network.
The lesson for buyers: score vendors on how many machines they can reach without controller access, what a new site costs without a vendor visit, and whether connectivity can route around a Wi-Fi refusal.
Coverage decides whether monitoring survives past the pilot. Resolution does not.
