When the EN camera is controlled by light sensor, user can monitor the shutter value in EN setup
software by accessing "Camera Shutter" status register (Address = 233). Note that this Shutter value
is dial number and not actual exposure time, (left side of the table above).
User needs to set appropriate "ADR Shutter Max" and "ADR Shutter Min" config registers (Address =53
and 58 respectively) to limit exposure time. In daytime, "ADR Shutter Min" limits the shortest
exposure time (or faster shutter speed). In night time, "ADR Shutter Max" limits the longest exposure
time (or slowest shutter speed). The factory default settings of "ADR Shutter Min" and "ADR Shutter
Max" are as follows: Factory Default Settings of the ADR Shutter Min. and Max.
Table 6 Factory Default Settings of the ADR Shutter Min. and Max.

6.3.3 Video Amplifier Gain Control
Normally, video amplifier gain is controlled automatically by an ADR (Automatic Dynamic Range)
control algorithm inside the EN, based on the output from the light sensor. However, the user can
manually change gain value by using the EN setup software (See Section 7.2 on page 47 for more
