The matrix by vehicle type

What goes into rail rolling stock

TENTAK MMI

Cab terminal — CCTV, lighting and passenger information in a single panel.

RAILFLECT

Digital mirror — exterior camera and cab monitor, local detection.

SENTINEL

Onboard CCTV, per compartment of the train.

Passenger Counter

ETH variant, OT3 thermal class (-25 °C to +70 °C).

Ethernet Switches

Onboard network for rail rolling stock.

Lighting

NRL001 bars — EN 50155 / EN 50121-3-2 test passed (ISQ, 2023).

Onboard network → ground

What stays on board, what reaches the ground

What each system records on board is only worth something once it reaches the ground. The PCC — Central Control Room — is NSS's platform for that side: where the fleet is tracked, an incident is handled and what to do next is decided. The integration sold today (via SAE) is on the road side; for rail rolling stock, connecting the onboard network to the PCC is handled case by case, using the same network protocols already in use on board — Ethernet, managed switches.
