OSD is the texts superimposed on a screen. It can show the menu

Synchronous System:
There are two modes for the camera synchronization. Internal
synchronization is realized by the synchronous signal which is
generated by the inside crystal oscillator.
ICR Auto Switch:
The filter will filter infrared light during the daytime and change to
normal filter at night to ensure a high sensitivity and clear image.
WDR (Wide Dynamic Range):
The wide dynamic range (WDR) function helps the camera provide
clear images even under back light circumstances. When there are
both very bright and very dark areas simultaneously in the field of
view, WDR balances the brightness level of the whole image and
provide clear images with details.
EIS (Electronic Image Stabilization):
Electronic image stabilization function can reduce certain ranges of
vibration which is caused by the external environment.
3D Digital Noise Reduction:
Comparing with the general 2D digital noise reduction, the 3D
digital noise reduction function processes the noise between two
frames besides processing the noise in one frame. The noise will be
much less and the video will be clearer.
HLC (High Light Compensation):
