Description
Increasing the resolution improves the video
quality but devours more bandwidth. The
options are as follows:
 1080P: The resolution is 1920 x 1080,
about 2 megapixels.
 720P: The resolution is 1280 x 720, about
0.9 megapixels.
 D1_PAL: The resolution is 720 x 576,
about 0.4 megapixels.
 D1_NTSC: The resolution is 720 x 480,
about 0.34 megapixels.

CIF_PAL: The resolution is 352 x 288,
about 0.1 megapixels.
 CIF_NTSC: The resolution is 352 x 240,
about 0.084 megapixels.
NOTE
 The PAL standard is applicable to China, Japan,
and Europe.
 The NTSC standard is applicable to America
and Japan.
You can set the bit rate type when Constant
bit rate is set to H.264.
Bit rate is the number of data bits transmitted
during a specified period.
 Constant bit rate: The average bit rate is
constant, while the compression speed is
faster. If the bit rate is improper, large
dynamic images are unclear.
 Variable bit rate: The bit rate varies
based on the image complexity to ensure
that large dynamic images are clear.
However, the compression speed is slow.
