If the frame rate is too high, the image will lag. At 30 fps, we see nearly a second of delay between something moving in the camera's field of view and the image showing that motion. At 10 fps, there is no significant lag at all.

The Dashboard is programmed in LabVIEW. You can create a new Dashboard project and customize it however you like. There is no problem putting a crosshair image, or rectangles, or text, or whatever you like, on the video display. Look in the Vision and Motion >> Vision Utilities >> Overlay function subpalette for things that you can insert between the existing IMAQ Clear Overlay function in the Dashboard image loop and the indicator for the image.

The Axis camera also supports an in-camera overlay feature. I've never used it, so I don't have detailed instructions for you. Basically, you create a picture and send it to the camera with appropriate settings. The camera will add that picture on top of whatever it sends back as an image.
