Causing images produced by a wireless camera to be presented on a display disposed on a vehicle
A video interface for signals between a wireless camera and a display, disposed on a vehicle, can include a microcontroller, a first port, and a second port. The microcontroller can be configured to process analog signals to produce digital signals. The analog signals can represent images produced by the wireless camera. The digital signals can represent the images for the display. The first port can be configured to be connected to an antenna, disposed on the vehicle, for the analog signals. For example, the wireless camera can be configured to be mounted on a trailer configured to be towed by the vehicle. The second port can be configured to be connected to a cable for the display. The video interface can be configured to be disposed on the vehicle. The wireless camera can have two external single pole antennas.

13 . The video interface of claim 12 , wherein:
the user interface comprises a turn indicator stalk, and
the user interface is configured to cause, in response to a position of the turn indicator stalk being in a specific position to cause a turn signal to be:
activated, a production of the at least one of the command signal or the control signal, and
deactivated, a cessation of the production of the at least one of the command signal or the control signal.
