Mount and wire your WTR20 wireless video transmitter and receiver correctly. Follow these steps for a clean, reliable setup and long-term care on board.
Quick answer
Mount the WTR20 transmitter and receiver in dry, secure spots with clear line of sight, then connect each unit using the simple 2-wire power connection. Keep the 35 ft wireless range in mind and secure all wiring to avoid vibration damage.
Why placement and power routing matter on a boat
The WTR20 is a universal wireless video transmitter and receiver with a 35 ft wireless range. On a boat, that range can be reduced by metal structures, enclosed cabins, or dense wiring, so where you mount each unit directly affects signal reliability. Choose locations that are as open as possible and away from large metal obstacles.
The 2-wire power connection is simple, but marine environments demand extra care. Vibration, moisture, and constant movement can loosen connections or chafe wires. Routing power leads through protected channels and using corrosion-resistant connectors will help prevent intermittent faults.
When the WTR20 is not the right fit
If your boat has multiple decks or heavy metal bulkheads between the transmitter and receiver, the 35 ft wireless range may not be enough. In that case, consider a wired video solution instead. Also, the WTR20 is not waterproof, so it must be installed in a sheltered, dry location; do not expose it to direct rain or spray.
Step-by-step WTR20 mounting and wiring
- Choose dry, secure locations: Select mounting spots for the transmitter and receiver that are sheltered from water and vibration. Keep them within 35 ft of each other with as few obstructions as possible. Common mistake: mounting inside a closed metal compartment, which can block the wireless signal. Check that both locations stay dry and have a clear path between them.
- Mount each unit firmly: Use the included mounting hardware or appropriate fasteners to secure each unit. Ensure the surface is flat and clean. Do not overtighten screws, as this can crack the housing. Common mistake: leaving the unit loose, which leads to rattles and premature wear. Give each unit a gentle tug to confirm it is secure.
- Route the 2-wire power cables: Run the power wires from each unit to a 12V power source, using grommets or conduit where passing through bulkheads. Keep wires away from sharp edges and moving parts. Common mistake: running wires through areas where they can be pinched or chafed. Protect wires with loom or clips along the entire run.
- Make secure, corrosion-resistant connections: Connect the two power wires to the boat's 12V supply, observing correct polarity. Use marine-grade butt connectors or terminal blocks, and apply dielectric grease to prevent corrosion. Common mistake: twisting wires and taping them, which fails in wet, vibrating environments. Tug-test each connection to ensure it is mechanically sound.
- Test the system before final reassembly: Power on the transmitter and receiver and verify video signal at the intended distance. If the signal is weak, adjust the mounting location or reduce obstructions. Common mistake: skipping the test and discovering issues after panels are reinstalled. Test with the boat in its typical operating configuration.
- Perform regular care checks: Periodically inspect the units for moisture, loose fasteners, and worn cables. Clean the housings with a damp cloth and mild soap; avoid harsh solvents. Common mistake: ignoring small cracks or corrosion until failure occurs. Add a quick visual check to your pre-departure routine.
Product facts
- WTR20: Universal wireless video transmitter and receiver with a 35 ft wireless range. Plan your mounting locations so the distance between units stays well within 35 ft and avoid obstructions that could shorten the effective range.

WTR20 - WTR20: Simple 2-wire power connection. Only two power wires are needed, so you can use existing 12V accessory circuits, but make sure the connection is secure and protected from moisture.
- WTR20: Small and easy to install. The compact size gives you flexible mounting options in tight spaces, but still allow room for cable routing and ventilation.
