You misunderstood about the "observation camera". It is a camera designed to be powered continuously while you drive mounted on the rear of the travel trailer (in essence a rear view mirror in use while driving).
While a "back up camera" is only designed to be used intermittently when the truck is in reverse using the power from the back up light circuit.
For a spy camera at the door, look into the Ring Door Bell system.
