Function Introduction
Record Stream Type

General & Event are available only for Primary Stream. General refers to continuous record video, while Event includes events that can trigger alarms, such as Motion, Exception, LPR and so on.

This item can separately set different bit rate and frame rate for different Recording Stream Types. If user chooses Event, video will be recorded according to the configuration of video stream type when an event happens, thereby greatly reducing the recording storage space.
Enable Event Stream This item is optional only if you selected the Event.
Video Codec

H.265/H.264/MJPEG are available.
Frame Size

Options include 8M(3840×2160), 6M(3072×2048), 5M(2592*1944), 5M(2560*1920), 5M(2560*1440), 4M(2592*1520), 3M(2304*1296), 3M(2048*1536), 1080P(1920*1080), 2M(1600 *1200), 1.3M(1280*960), 720P(1280*720), D1(704*576).

For Secondary Stream, it includes 704*576, 640*480, 640*360, 352*288, 320*240, 320*192, 320*176.

For Tertiary Stream, it include 1920*1080, 1280*720, 704*576, 640*480, 640*360, 352*288, 320*240, 320*192, 320*176.

Note: The options of Frame Size are variable according to the model.
Maximum Frame Rate

Maximum refresh frame rate of per second and it is variable according to the mode.
Bit Rate

Transmitting bits of data per second, this item is optional only if you select the H.265/H.264

Set the bitrate to 32~16384 Kbps. The higher value corresponds to the

higher video quality, and the higher bandwidth is required as well.
Smart Stream

Optional to turn On/Off Smart Stream mode. Smart Stream mode remarkably reduces the bandwidth and the data storage requirements for network cameras while ensuring the high quality of images, and it is a 10-level adjustable codec.

Level: Level 1~10 are available as needed.
Bit Rate Control

CBR: Constant Bitrate. The rate of CBR output is constant.
Bit Rate Control

VBR: Variable Bitrate. VBR files vary the amount of output data per time segment.
Image Quality

Low/Medium/High are available, this item is optional only if you select VBR.
Profile

The option is for H.264, Main/High/Base can be selected as needed.
I-frame Interval

Set the I-frame interval to 1~120, 50 for the default. This item is optional only if you select the H.265/H.264. The number must be a multiple of the number of frames.
