different housecodes, same unit code triggered on both

[birdzeye]

One camera on B11 and a light on E11 are both turning on when only the B11 camera is triggered ON by RF remote. Why is this happening?

I've never heard of a duel RF signal coming from a remote.
Barring a macro to tell it to turn on the other, it appears that the devices functionally consider themselves on the same address.
There's a chance that the dial setting is wrong or even a small chance that the setting dial is defective. Go to to the device that shouldn't be coming on and reset it's code. If it has dials, rotate them a few times before resetting.

also try different house codes on remote or try using another rf sending device to see if its a bad remote
