Your footage,
on your phone.
Automatically.
Your clips sync over WiFi, locally, with zero monthly fees.
CardBridge syncs clips from all your cameras — dashcam, drone, action cam, DSLR, and more — automatically to your phone. One unit handles everything simultaneously. Footage goes directly to your phone, nothing stored on the device. No SD removal. No manual transfers. No cloud.

CardBridge
Raspberry Pi Zero 2W
From camera to phone in 3 steps
After a one-time 5-minute setup, this is all you ever do. One CardBridge unit handles all your cameras at the same time.
Arrive home. That's it.
For dashcams with a WiFi SD card, syncing is fully hands-free — no cables, no touching anything. For drones and cameras, a quick USB plug-in is all it takes. Either way, everything after that is automatic.
CardBridge syncs automatically
New clips are detected in real time and transferred to the Pi. No apps to open, no buttons to press. It just works.
Open the app — clips are there
Open the CardBridge PWA on your phone. Your footage is ready to watch, sorted by device, streamed in full quality.
First time? Setup takes 5 minutes — power on your CardBridge unit, scan the QR code in the box, connect to WiFi.
A workflow for each recording style
Dashcam commutes, drone weekends, action-cam trips. Same simple flow.
Dashcam
Never touch the SD card again
For truly hands-free sync, the Dash kit's WiFi SD card lets your dashcam keep recording while clips transfer automatically in the background — no cables, no card removal, no interaction. USB sync is also supported for manual sessions when you park.
Viofo, BlackVue, Thinkware, Nextbase, and most dashcams.
Drone
Sync the moment you land
Get home, connect your drone once. Walk away. The footage is on your phone by the time you sit down — no file management, no card removal, nothing.
DJI drones and other models that support USB Mass Storage mode. Check your model's settings — not all drones work by default.
Action camera
From camera to phone in seconds
Connect once, then forget about it. Your GoPro, Insta360, or action cam clips appear in the app automatically, without lifting a finger.
GoPro, Insta360, DJI Osmo, and any action cam with USB Mass Storage mode enabled.
On the go
No home WiFi needed
Share your phone's data plan. CardBridge connects to your personal hotspot and syncs your footage anywhere — no router, no fixed network required.
iPhone Personal Hotspot, Android Hotspot, or any mobile WiFi.
And much more
Works with most USB cameras and SD card readers
Requires USB Mass Storage mode (the device appears as a drive on your computer). Most dashcams, trail cams, body cams, and SD readers work out of the box. Some drones and action cams may need storage mode enabled in their settings.
Stop doing transfers the hard way
CardBridge removes repetitive steps without locking you into a cloud subscription.

"I shoot drone footage every weekend. Before CardBridge, I'd spend 30 mins syncing. Now? By the time I'm home, everything's on my phone. Complete game changer."
Sarah Chen
Content Creator & Vlogger
"Managing 15 dashcams across our fleet was a nightmare. No cloud vendor was trustworthy. CardBridge gave us local control and our drivers love the simplicity."
James Rodriguez
Fleet Manager
"I've audited the code myself. It does exactly what it says — your footage never leaves your home. That's worth everything to me."
