Notes:

Few times, Amazon shipped wrong camera to customers by their mistake. If you order NDI camera, but you received wrong camera(No NDI), pls contact avkans.pro@gmail.com. We can update your Camera to be NDI camera. The camera updated will be the same NDI camera you re-order. 

If you order HDMI camera, you may receive NDI camera, then you are the lucky one, keep it and enjoy it.
