    Manual for the SECO-LARM ENFORCER NE-AE01-030TQ Ethernet over Coax with PoE — extends a PoE Ethernet device, such as an IP camera, over existing coax cable, delivering both data and power over a single run up to 984ft (300m).

    Overview

    This transceiver pair is designed to connect a PoE camera or other PoE device using existing coax cabling — perfect for upgrading an old analog CCTV run to a modern PoE IP camera without pulling new cable. It supports IEEE 802.3af/at PoE standards and 10/100 Mbps Ethernet speeds.

    Key Features

    • Extends powered Ethernet devices (e.g., PoE cameras) over existing coax cable
    • Connects PoE cameras to 10/100BaseT PoE injectors/switches over a single coax cable
    • Supports PoE: IEEE 802.3af/at
    • Supports 10/100 Mbps transmission rate
    • Extends up to 984ft (300m)
    • Note: works only with PoE-compatible devices

    Parts List

    • 2x Transceivers
    • 2x 6" Cat5e crossover Ethernet cables
    • 8x Mounting screws
    • 8x Plastic wall anchors
    • 1x Manual

    Sample Installation

    1. Determine the locations for the two Ethernet-over-Coax units and how much coax cable is needed.
    2. Ensure the PoE mode switch is set correctly on both units (default: Mid Span). Important: disconnect the Ethernet cable from the PoE switch before switching PoE modes to avoid damage.
    3. If your PoE switch supports "Auto MDI"/"MDI-X" mode, use two standard Cat5e/6 cables (not included, max 6.5ft/2m) to connect the camera to one transceiver and the PoE switch to the other.
    4. If your PoE switch does not support Auto MDI/MDI-X (or the mode is undetectable), use the included crossover patch cables instead.
    5. Connect the coax cable between the two transceiver units.
    6. Power on and verify the green LED lights above each unit's Ethernet port. For distances over 328ft (100m), manually set the PoE switch link speed to 10Mbps.
    7. If not functioning correctly, repeat steps 2~5 with the PoE mode set to "End Span" on both units.

    Troubleshooting

    Issue Solution
    PoE device doesn't function properly If distance is over 328ft (100m), set link speed to 10Mbps. Check the PoE mode switch is set the same on both transmitter and receiver. Confirm both the input and output devices are powered on. Test the coax cable between receiver and transmitter. Try installation again using the crossover cables with PoE mode set to "End Span."
