I have an analog camera signal, the power for the camera, and a dc motor which is activated by a switch and all share the same ground. When the motor is activated, the video feed blanks out for a second. I tried putting a capacitor on the + - rail but that didn't do anything. What can be added to this circuit to prevent the video signal from being interfered with?
In the illustration below, when the switch/button is pressed, the lcd screen blanks out because some sort of interference is being caused but the presence of the electric motor. This interference happens when the motor is switched on and under load AND when again when it is switched off but not while it is on! I can't change the wiring but I can add something to the circuit to filter out the interference somehow. What can be added to this circuit to prevent the video signal from being interfered with?
