Onboard IP networks and CCTV installation
NAVION designs, installs and services vessel IP networks and camera systems in Busan and its ports, Vladivostok and China: bridge and accommodation cabling, managed PoE switching, VLAN separation of navigation and crew traffic, accommodation Wi-Fi, and IP cameras recording to an onboard NVR. Remote viewing is set up over the vessel's own satellite link and tested against it, not against a shore connection. The work is scheduled inside the port-call window and handed over documented.
Message us on TelegramA fishing vessel already runs a data network whether anyone planned it or not: chart machines, sounder and sonar processors, a Marport receiver, an AIS and NMEA gateway, the satellite modem, crew phones, and now cameras. On one flat subnet behind an unmanaged switch under the chart table, the failure modes are predictable: duplicate addresses after a blackout restart, a broadcast storm that stalls the plotter feed, a crew download eating the airtime during a set. Planning the vessel IP network removes that whole class of problem.
What the job includes
- Network survey and IP address plan
- Structured cabling, bridge to accommodation
- Managed PoE switch and cabinet installation
- VLAN segmentation of navigation and crew traffic
- IP camera installation on deck and in machinery spaces
- NVR installation, recording and retention setup
- Accommodation Wi-Fi coverage
- Remote viewing over the satellite link
- Network hardening and credential handover
- Fault-finding on an existing vessel network
Timing
- Survey and network audit
- 2-4 hours
- Adding one to three cameras
- typically 4-8 hours alongside
- Full CCTV system with NVR
- typically 2-4 days
- Network rebuild with VLANs
- typically 1-2 days
- Accommodation Wi-Fi coverage
- typically 1-2 days
What we need from the vessel
- Access to the bridge, accommodation alleyways, engine room and the deck areas to be covered, with hot-work permits arranged if brackets need welding.
- A supply at the planned cabinet position, ideally on an emergency or UPS-backed board, and confirmation of who may open the distribution panel.
- A crew electrician or fitter for routing through cabins and for any penetration the vessel does not want cut by an outside contractor.
- Existing network details where they exist: modem and router credentials, satellite airtime plan, current switch and NVR passwords.
- A short quiet period on the bridge for addressing and reboot testing, when navigation displays can be restarted safely.
- A decision on who ashore gets remote access, to which cameras, and for how long.

Frequently asked
Can you add cameras to the NVR we already have?
Usually yes, if the recorder and the new cameras both speak ONVIF or the same manufacturer protocol, and the recorder has channel licences and PoE ports left. We check the model, firmware and free channels during the survey and tell you before ordering whether it will work or whether the recorder is the limiting part.
Will CCTV and crew Wi-Fi slow down the satellite link?
Only if they are configured to. Recording stays on board; nothing goes over the satellite link unless someone ashore asks for it. Remote viewing uses a low-bitrate sub-stream and event clips, and crew traffic sits on its own VLAN with per-user limits, so navigation and telemetry keep priority.
