How high is the mobile phone bracket suitable for postgraduate entrance examination and re-examination

Generally, except for the second seat behind the examinee, it is no longer recommended to have other sundries, so we need to prepare a mobile phone stand, which is mainly used to place the second seat (auxiliary seat). 45 behind, distance from me1m. After sitting down, the average person's height is about 80 cm-1 10 cm. It is suggested that the height of the bracket can be adjusted to 140cm. Because if you shoot from a higher angle, candidates' screen income will be greater and more complete, and it is easier to meet the conditions.

The requirement in the second interview is that the camera on the mobile phone can be used as the "second position" to shoot from the back of the candidate at a distance of 1m, and can capture the side of the candidate and the full screen of the main equipment computer. Make sure that the interviewer can clearly see the screen in the first position from the second position.
