I am not entirely sure I understand your question, but am I correct that you want to use the tablet as the camera? If so you can use the Milestone Mobile Client to do video push. Please have a look at the Mobile Client documentation for further info on this, or if you want to make your own app please consult with the MIP SDK Mobile documentation: https://doc.developer.milestonesys.com/mipsdkmobile/.
Thanks Peter, It´s correct. I will check the Mobile SDK Documentation.
