How to Record Boat Telemetry Video
Recording on the water is mostly about setup. Once the mount is right and the phone has a GPS lock, VelocityCam behaves the same as it does on land — but the environment adds constraints worth planning for.
1. Protect the phone
VelocityCam does not make the phone waterproof. Use a marine-rated mount and, where appropriate, a waterproof case. Keep the phone out of direct spray, submersion, and prolonged sun.
2. Get a clear view of the sky
GPS reception on the water is usually excellent because there are no buildings or canopy in the way. Mount the phone somewhere the top of the device is not covered by metal.
3. Wait for GPS lock, then record
VelocityCam blocks recording until GPS is locked. Once recording, GPS-derived speed tracks the run in real time on the Performance HUD, capturing how the boat handles swells and turns.
4. Route Trace playback
With VelocityCam Pro, Route Trace overlays the run's GPS path during Library playback and in exported video. Mini Inset keeps it compact; Full-Screen Ghost Route takes over the frame, and Top Speed, Best 10s, and Best 30s are highlighted along the route. Route Trace works entirely offline — no map tiles are downloaded and no map API key is required, and it is not drawn on the live recording screen.
5. Export and share
Export the session in the format you want to share. GPX and KML route exports (Pro) let you review the run in other tools. The original recording is left untouched.
FAQs
Do I need cellular data on the water?
No. Recording, playback, Route Trace, and export are offline.
Can I keep the phone in an under-console position?
You can, but the camera needs to see what you want to record and the phone needs a clear enough view of the sky for GPS. Test the position before a real run.
