GOV Settings
Users 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 setting is 30 . Click SAVE to confirm the GOV setting.
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.

Video Compression
From the Video Compression page, you can specify MJPEG and H.264 compression settings.
