It's not a Truvelo as their flash is Infra-Red.

I know a guy who used to install Gatsos (i.e. a very good source) and he said that if they flash oncoming vehicles then they are loaded with a dummy camera. He says that in a live camera the radar is directional i.e. ignores oncoming traffic.

I really wouldn't worry about it. I'm sure you won't get a NIP.
