We apply ?amp glow reduction technology? to our ASI224MC and ASI224MC-C camera, it is a hardware modification to reduce the amp-glow of the sensor, not every sensor can benefit from this modification, but it is obvious for ASI224MC, so this upgrade is for ASI224MC  and ASI224MC-C only . We made this change since April 2016, which means the current unit (ASI224MC and ASI224MC-C) we produce all equiped with the newest PCB version ?V1.3.
