Theoretical exposure time of shutter in each TV standard is as follows.

However, It is recommended to moke exposure not more than 2sec. since
visible dark-current nolse may occur on video signal due to the long time
exposure on CCD Image sensor.
2.
Do not Input Ext. VD signal at pln no. of
6P Multi connector.
Caution on Long Time Exposure Mode

(The falling edge of int. HD signal and Ext. VD signal are
phase-synchrozied.)
