- Step 1: Use the computer to start the stopwatch timer, and the camera is facing the stopwatch; use the mobile phone to take pictures of the time displayed on the computer and the monitor at the same time;
- Step 2: When not connecting to Cosmo C1: Computer time—Time1, monitor time—Time2; DT1=Time2-Time1;
- Step 3: When connecting to Cosmo C1: Computer time—Time3, monitor time—Time4; DT2=Time4-Time3;
So the delay of image transmission = DT2-DT1
