Can I get voltage sensitive power control?
I'm putting a wireless backup camera on my car hauler trailer and I want it to be powered up only when the truck is running. So I'd like to use the hot feed coming from the truck to power the trailer ...

Of course there's a breakaway battery, but it's not relevant. I'm not going to use it to power a camera for the obvious safety reasons, plus that would make the camera always-on which is worse than just having it on whenever the truck is connected. I only want the camera on when the truck is connected AND running.
I'm not going to rework the 7 way connector to get an ignition-hot feed to the trailer so I can use a relay. If I can't find the equivalent of a vsr that works without a battery on the load side of the relay, then I'll just feed the camera from the running lights. But my strong preference is to have it automatically on when truck is running, and off when truck is not.
Thanks,
Fred
