LOCAL·SIMPLE·AUTOMATIC·
Your footage,
on your phone.
Automatically.
Your clips sync over WiFi, locally, with zero monthly fees.
CardBridge syncs clips from any recording device — dash cam, drone, action cam, DSLR, trail cam, body cam, and more — to your phone over WiFi. Privately, on your network, zero monthly fees. No SD removal. No cloud.
How CardBridge works
+ security cams, 360° cams, baby monitors…
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.
Plug in or insert WiFi SD
Connect any USB Mass Storage device — dashcam, drone, action cam, DSLR, trail cam, or SD card reader. CardBridge detects it instantly, no button needed.
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
CardBridge lives in your car. When you pull into the driveway, clips are already syncing. No cables, no card removal, no interaction.
Viofo, BlackVue, Thinkware, Nextbase, and most dashcams.
Drone
Sync the moment you land
Plug your drone into CardBridge when you get home. Walk away. The footage is on your phone by the time you sit down.
DJI Mini, Air, Mavic series and any drone with USB Mass Storage.
Action camera
From camera to phone in seconds
One cable, one plug, automatic transfer. Your GoPro, Insta360, or action cam clips appear in the app without lifting a finger.
GoPro, Insta360, DJI Osmo, and any USB Mass Storage camera.
And much more
Any device with a USB port or SD card
If it has a USB port or SD card, it works with CardBridge.
Stop doing transfers the hard way
CardBridge removes repetitive steps without locking you into a cloud subscription.

Your footage stays with you
CardBridge is local-first by design. Transfer clips inside your own network, without depending on external cloud storage.
Your footage stays home
Everything syncs over your local WiFi. Your clips never leave your house. We never see a single frame.
No internet required
Once set up, CardBridge works entirely offline. No cloud service to go down, no login to expire, no terms to change.
Fully open source
The entire firmware and app are on GitHub. Self-host it, audit it, modify it. No lock-in, ever.
Device Management
All your devices,
one dashboard
CardBridge auto-detects every device the moment it's connected. See storage, clip count, and last sync time — all from your phone, without touching a single SD card.
- Auto-detected the moment a device is connected
- Storage usage and clip count per device
- Last sync timestamp — always know what's fresh
- Custom device names (Viofo, Mini 3, Hero…)
- Multiple devices syncing simultaneously
