Leaving the video facing across the body of the vehicle meant we had to walk down to the thing to use the remote control.
I solved the problem by cutting one ‘blister’ from a lozenge pack and pushing the foil seal (left partially attached) into one half of it. I then taped the blister over the infrared receiver window with the open end facing the front seats.
The foil acted as a mirror for the infrared signal, turning it at 90 degrees, straight into the receiver window!
It’s a principal which will work for any remote control where the receiver is in an awkward position.
