The TRiOTop Video Gateway System is an integrated inspection and monitoring package built to support the TRiOCam and TRiOLight range, powered from the surface and interfaced subsea through the TRiOBoost-S signal extender system. A portable topside display and control unit connects to the subsea package via an umbilical, delivering a field-ready system for deployment, viewing, and control. At the surface, the gateway provides a clean operator interface for live video display, lighting control, and 4-20 mA sensor monitoring. Alongside video, the display presents real-time measurements from two 4-20 mA inputs. These displays can be configured in various layouts to support inspection and alignment tasks in demanding environments. For maximum portability, the topside unit includes internal batteries capable of up to approximately 6 hours of operation with lights off and up to approximately 3 hours with lights on, enabling short campaigns and rapid mobilisations with or without an external power source.
