01
The Challenge
Remote sites and confidential meetings have requirements that off-the-shelf hardware rarely meets: secure cloud connections, compact units that install quickly, reliable operation on site, and privacy for the people in the room.
Stock products fail one or more of these requirements, so the work needed custom hardware.
02
The Solution
A suite of three devices, each built on custom hardware: the 4G Compact Camera, the 4G Remote Audio Monitoring Unit and Guardian Dock, a meeting privacy dock.
All three are built around in-house PCB designs, with firmware optimised for secure connections and battery life.
