Exposure mode/ shutter speed

Hi, I have generic Chinese camera, 1080p PTZ 18x zoom. I wanted to set it as LPR camera but changing exposure mode does not change anything! I was able to turn down AE so that I can read LP quite OK (with tape over IR sensor to force IR mode) but I have no idea how to actually turn down shutter speed to 1/2000 or 1/4000 or to check what is it set to right now. Any tips?
