Now that poor "Roadkill" has been replaced, there seems to be a problem with the camera signal. The video saved is clean and clear, but the view on the ST10 and the ST12 is erratic. Screen splits at time and there seems to serious lag. Does same thing on both controllers, almost like it is getting out of range, but it's happening within 20 to 100 ft. Don't remember the original camera acting this way. Is this normal or should I be asking for a warranty claim. Has 12 month warranty and only had it a couple weeks
