I am having difficulty with my ew Elmo TT-02S Document Camera. I have noticed that when writing during "live action," there is a definite lag time between the video of the image and the live action itself (i.e. as I write on the tablet, all movements appear very choppy). This could be quite confusing to students as I write notes suing the document camear. Any idea? Thanks.
There is nothing wrong with your Elmo. The effect you are seeing is due in part to the speed/frame rate of the camera.
To minimize the lag you can zoom out and make sure you have sufficient light on what you are showing.
