What is it you'll be filming with front, rear and 360 footage? Off on a trip somewhere?
Good question.
I'm setting up front and rear cameras at 1080p 60 frames per second for accident/incident recordings.
I've got 128GB fast memory cards which are shock-waterproof and the camera's will be set up for a 5 minute file rolling recordings.
The front and rear cameras are fixed to bike and linked Master-Slave. So whatever I ask them to do, both will do the same, and video footage is GPS timestamped so always in sync and always mirrored with bluetooth voice overlay.
If the camera detects a severe G-Force jump (like an accident) it'll write protect the file its recording on. If I use voice activation to protect a file, it'll do that as well.
If direct power feed is cut or switched off, they'll revert over to battery power so you should always get enough footage (even after you've left the bike if necessary).
Idea being that the only files left at end of day will be noteable 'protect' files, which save huge amounts of editing. Download them all if wanted and reformat card for next ride.
All waterproof out of the box.
The Garmin Virb 360 on helmet is just superb, take a look at it. That'll be used for noteable events or 360 degree accident protection.
I'm using mine for trips, safety, Blood Bike work and training purposes.
