On-board solution

Satlink has designed this solution to integrate all on-board electronic monitoring technologies. Collected data is encrypted to ensure its privacy and confidentiality; the system cannot be tampered with.

  • control-unit-ad7d3a7b Electronic monitoring
    SeaTube components


    The SeaTube control unit is the “brain” of the system. It powers all components of the system and manages the recording and storage of information (video and data). The core unit is normally connected through a UPS (uninterruptible power supply) to the vessel’s power supply.

  • EM-Camara2-501439f5 Electronic monitoring
    SeaTube components


    SeaTube is designed to work with PoE cameras and supports up to 4 (Nano) or 8 (Nano+) cameras without additional hardware. These cameras can record video in a resolution of up to 2 MP (1920x1080) and offer the highest image quality on the EM market, even in dark environments.

    The cameras are mounted with Satlink’s proprietary waterproof housing, making them the only ones on the market to achieve IP-68 (submersible) grade.


  • almacenaje-electronic-monitoring-f33f009b Electronic monitoring
    SeaTube components


    The SeaTube control unit has 2 (SeaTube Nano) or 4 (SeaTube Nano+) removable HDD/SSD hard drive bays (2.5” and 7 mm high).

    All video, image, sensor and metadata recordings are stored on removable HDD/SSD for their later transmission. It can manage up to 4 SSDs of 8TB, storing data for periods of up to 1 year without any additional hardware.

  • cam-repeater-mock-up_r-fa959f27 Electronic monitoring
    SeaTube components


    The SeaTube Cam Repeater unit is a portable computer that is installed on board the vessel with a web browser for watching camera-generated streams, as well as displaying system health status and sensor information in real time.
    The SeaTube system allows as many Cam Repeaters on board as needed, enabling the captain to monitor on board operations.

  • sensores-grafico_r-b766efa9 Electronic monitoring
    SeaTube components


    Depending on its configuration, the SeaTube may include a sensor box along with several connected sensors.
    The sensor box supports up to 8 analogue and 8 digital sensors. While more features can be added on demand, the system currently supports the following sensors: hydraulic, rotation, light, temperature, main haul door opening, crane scale.

  • EM-Antena_r1-50ef35a3 Electronic monitoring
    SeaTube components


    SeaTube can relay the output data through any communications gateway, including:

    • A satellite communications unit
    • A GSM/4G router
    • A VMS unit (type-approved)
    • A Wi-Fi router
    • Any pre-existing IP satcom device

    All transmissions are made via secure protocols (HTTPS type).

  • gps%20unit_r-ddce799f Electronic monitoring
    SeaTube components


    The system includes an external GPS unit to retrieve position information and can use the connectivity unit to relay this data on shore, etc.
    SeaTube accurately tags videos and updates the position watermark on the video periodically.

    On shore Solutions

    Satlink has designed a powerful suite of software tools to optimise the on-shore review of fishing videos and to provide an effective fleet management tool.

    • satlink-view-manager-software-web-d725b280 Electronic monitoring


      Satlink has developed its own proprietary software to offer the best tool to thoroughly analyse data obtained from EM systems and generate reports.
      The SVM provides all the necessary tools to review videos in a timely manner (i.e., speed and time filtering, synchronous camera player, sensor graphs, playback speed settings, etc.).
      It includes several default fishing profiles to assist EM analysts while tagging footage and offers a measuring tool to analyse fish sizes.
      Once the EM analyst work is completed, the SVM automatically generates reports in the different formats required by regulators.

    • fleet-management-tools_cuadrada-39d37463 Electronic monitoring


      Satlink has developed a web platform that allows regulators and fleet owners to efficiently manage their fishing operations in real time.
      This is particularly useful for real-time compliance objectives (i.e., compliance with fishing closure periods or corporate codes of conduct).
      This tool shows the position of each vessel in the fleet on a map and, if equipped with a broadband connectivity module, can display images at fixed intervals.
