SumLight™ Function

The SumLight™ function substantially increases the sensitivity of the CMOS array in the event of a reduction in the light level, thus enabling observation in conditions of low light without using the IR illuminator.

  1. Turn off the IR illuminator before using the SumLight ™ function.
  2. To activate the SumLight™ function, press briefly the LEFT (8) button.
  3. Press the LEFT (8) button once more to switch off.
  4. The SumLight™ icon (on or off ) is displayed in the status bar.

Attention! When the SumLight™ function is activated, the noise level in the image increases, the frame rate decreases and the image slows down. Any sharp movement of the device may cause the image to become “blurred”. Such effects are not defects. Luminous white dots (pixels) may be visible on the device’s display. The number of dots may increase when the SumLight™ function is enabled. This is due to the nature of how this function works and is not a defect.
