First of all I do not have an LED walk test light hooked up to either of my cams and the do not have timers. When I intially power up the sensor I leave the camera power on, but switch off the connection to the relay. The trouble is when I turn it on the camera always takes a pic. Is this normal? It works fine after that. I just don't want to always waste that first pic when i turn it on. Is this normal. I am pretty sure I hooked both sensors up OK.
