Suppose the displayed image of the camera is shown as follows.
To rotate the image vertically, for example, select Flip video. The displayed image is reversed as
shown below.
Following are descriptions of different video rotate types.

Normal video – The image appears as it is viewed.

Flip video – The image is reversed along its horizontal axis.

Mirror video – The image is reversed along its vertical axis.

90 degree clockwise – The image rotates 90° clockwise (to the right).

180 degree rotate – The image rotates 180° counter-clockwise (to the left).

90 degree counterclockwise – The image rotates 90° counter-clockwise (to the left).

7.4.1.5 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 2 to 64. A longer GOV means decreasing the
frequency of I-frames. Click Save to confirm the GOV setting.
7.4.1.6 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
