Is the Tiny Traveler fully wireless, or do the camera and monitor require physical power cables?

The video connection between the camera and monitor is wireless, so no video cable is needed between the front and back seats. However, the standard camera still needs power while in use.

Full Answer:
Tiny Traveler uses a wireless video connection between the backseat camera and the dashboard monitor, so you do not need to run a video cable through your car.
The monitor has a built-in rechargeable battery, but for everyday driving, we recommend keeping it plugged in.
The standard camera does not have a built-in battery, so it needs to be connected to power using the included cable. For a cord-free camera setup, you can use the optional Portable Power Bank Cradle.
