9.4.1.1.3 GOV Settings
You can set the GOV length to determine the frame structure (I-frames and P-frames) in a video stream for
saving bandwidth. The setting range is from 1 to 255. A longer GOV means decreasing the frequency of I-
frames. The default GOV setting for H.264-1 and H.264-2 is 25/30 (PAL/NTSC). The default GOV setting for
H.264-3 and H.264-4 is 25/30 (PAL/NTSC). Click

9.4.1.1.4 H.264 Profile
The H.264 standard defines 21 sets of capabilities. These are referred to as profiles and they target specific
classes of applications. In the security industry, the most common are as follows:
·
Baseline Profile (BP)
Primarily for low-cost applications that require additional data loss robustness, Baseline Profile is
used in some videoconferencing and mobile applications. This is the most common profile used in
IP security cameras due to the low computational cost of processing the video using this profile.
·
Main Profile (MP)
This profile provides improved picture quality at reduced bandwidths and storage costs and is
becoming more common as the camera processors (DSPs) become more able to handle the
processing load.
Main Profile can save 10-12% over Baseline . This is the default profile.
·
High Profile (HP)
High Profile is the primary profile for HD broadcast applications. It can save 10-12% of the storage
cost over Main Profile . However, it may also increase video latency, depending on the stream
structure. Units default to the Main Profile to provide the best trade-off between storage size and
video latency.
