Must have WiFi sender in trunk

Works well for the price. WiFi sender is about 15 inches from camera. Yet power cord is 6 or 7 feet long. Slight flaw, the WiFi unit should be 6ft long so it's closer . Just behind rear seat would be ideal. Luckily WiFi unit just reaches my trunk in a BMW Z4. So unit is just behind me. Tried placing unit in my bumper, but video was jumpy. Had to drill hole into the trunk. Now video is perfect. Real time.I tapped into license plate light
