have installed a camera and set it up the problem I have it displays mirror image to actual IE should i have a blank work sheet and place a white sticker bottom right it displays top left ,but the framing will be where the sticker has been placed. I need to mirror image the camera to correct this may even have to flip left to right as well. is there a control for this. My mount is at rear to make this work I would need to have the mount at the front ( in the way)
