between manual and automatic settings. The camera offers 3 gain levels (L/M/H) that you can select simply by
changing the position of the ISO/GAIN switch. By choosing manual settings you can change the ISO speed or
gain value to adjust the sensitivity of the sensor.
You can also perform this function remotely using Browser Remote on a connected network device (A 177,
