4.2 Basic Setup

Basic Setup includes setup for video, audio, and image settings.

Resolution, frame rate, etc. can be adjusted in this section. Each setting can be adjusted per stream. There are 3 streams in total – one main

stream and two sub streams.

Codec: For the main stream and sub stream 1, this is set to H.264. For sub stream 2, there is an option to choose between

H.264 and MJPEG.

Resolution: Set the desired resolution for each stream from the drop down list.

Frame Rate: Set the desired frame rate for each stream from the drop down list. Range is from 1 fps to 30 fps.

G.O.P: Stands for "Group of Pictures". This determines how many frames are processed in between unique I-frames. For example, if the frame

rate is set to 30 fps and the GOP value is set to 1, there would be 30 I-frames per second. I-frames contain much more data compared to P-

frames or B-frames. The higher the GOP value, the higher the image quality will be. For decoding process considerations, GOP should be set to a

value equal to or greater than the frame rate.

Bitrate Mode: Choose between CBR (constant) or VBR (variable). The bit rate used in video encoding has a direct impact on the video quality

and the bandwidth used to stream video over the network. As opposed to constant bit rate (CBR), VBR files vary the amount of output data per

time segment.VBR allows a higher bit rate (and therefore more storage space) to be allocated to the more complex segments of media files while

less space is allocated to less complex segments. The bits available are used more flexibly to encode t he video data more accurately, with fewer

bits used in less complex scenes and more bits used in complex scenes. CBR is the best option if the available bandwidth must be limited.

Bitrate: Sets the target bitrate. The acceptable minimum bitrate is around 1 Mbps per megapixel. So a 1080p resolution (2MP)

should be set to 2Mbps at a minimum.

Profile: Select between Baseline, Main, or High profiles for H.264.

Corridor View: This changes the camera view from a landscape view to a portrait view. This mode is useful for looking down a narrow

hallway for example.
