Date Format: The user can choose YYYY-MM-DD, MM-DD-YYYY, or DD-MM-YYYY.

Brightness: It indicates the lighting intensity at a unit projecting area. Increasing the brightness

helps in improving the general image effect; however, high brightness may cause insufficient

transparency of images. The setting range is 1 to 10.

LPRC300 User Manual

Contrast: It is the key factor to the visual effect. In general, the higher the contrast, the clearer the

images, and the more distinct the color. A lower contrast makes the entire image dim. The setting

range is 1 to 10.

Saturation: It indicates the brilliance of color and is also called the purity of a color. The higher

content of coloration, the higher the saturation. The higher content of discoloration, the lower the

saturation. The setting range is 1 to 10.

Hue: The color is presented by brightness and hue. Hue indicates the color properties excluding the

brightness and shows the tone of colors. The setting range is 1 to 10.

In the lower right corner of the interface, the display position of the title text, date, and time can be

adjusted, and the color and font of the text can also be set.

3.4.4 Streams

Stream is used to view or set the video code. It includes the parameters of Main Stream and Sub

Stream. The user can set this feature based on requirements and click [Save].

 Stream Type: "Mainstream", "Sub Stream" and "Third Stream" are available. The mainstream is

generally larger, with high definition and large bandwidth. The sub-stream and the third stream

has a reduced image format under the image environment of the mainstream, and the definition is

lower than that of the mainstream, occupying less bandwidth.

 Video Stream: The Mainstream has two options: "Video & Audio" and "Video". The Sub-stream

supports only Video & Audio.

 Resolution: The user can choose 1080P (1920 x 1080), 720P (1280 x 720), D1 (720 x 576), VGA (640

x 480) and CIF (352 x 288). (Note: The default resolution shall prevail.)

 Frame Rate (F/S): It indicates the number of compressed frames transmitted in every second by

the network module. The greater number of frames, the more coherent images, and also it lowers

the performance of the CPU in processing other events. The setting range is 1 to 25 or full. The

default is full.

 Video Encode: It indicates the video coding format. The user can choose H264 or H265.

LPRC300 User Manual

 Encode Level: It indicates the level of video coding. The user can choose the Baseline, Main Profile,

or High Profile.

 I-Frame Interval: An I-frame (Intraframe) is a complete keyframe used in compressed code

between frames, where the interval variation between I-frames will also modify the duration of the

GOP (Group of Pictures). The number of frames between two I-frames may affect the speed of the

GOP reading. If the interval between I-frames is too large, B and P frames will be used automatically

to reduce the consumption of total bandwidth. In this case, the image quality will be reduced.

Therefore, it is recommended to avoid large interval between I-frames. The setting range is 2 to 255.

 Bitrate Type: The bitrate type can be Variable or Constant.

 Variable: It is used when the image quality is constant, and the network bandwidth is

sufficient.

 Constant: The images are transmitted over a fixed bandwidth.

 Bitrate: It shows the maximum limit of the bit rate, which can be individually entered. The larger

the bit rate, the larger the energy use, and the greater the picture quality. The range is 16 Kbps to

16 Mbps. (Note: The standard bitrate shall prevail).



Note: The coding level is related to the coding algorithm. The coding levels comprise

Baseline, Main Profile, and High Profile when the coding algorithm is H264. The coding level

cannot be edited when the coding algorithm is H265.

 Quality: The user can choose from the Highest, Higher, High, Bad, Worse, or Worst. When the

image quality is set high, the images are clearer with better effect, and the higher the occupation

of resources.

3.4.5 Video Parameters

Here, the user can set the video parameters (do not randomly change the default parameters),

including Day & Night mode, Advanced Settings, Exposure Control, Aperture, Gamma, and Light

Board Control.

 Day & Night Mode: The Day & Night mode of the camera can be set using any one of the mode

Auto, or DayTime Period. The default mode is Auto.

LPRC300 User Manual

 Auto: In this format, the Day & Night format can be tuned automatically based on the

camera's visibility and color of the video images. Meanwhile, the camera fill light (i.e.,

photographic lighting of the camera) brightness can be adapted or switched off

automatically depending on the environment's requirements.

 DayTime Period: In this format, set the parameters with the same number of intervals for

the start and end period of the daytime so that the fill light will automatically be switched on

during night-time. For example, if the start time is set as 06:00:00 and the end time is set as

18:00:00, then the camera's fill light does not work between 06:00:00 and 18:00:00, and the

camera's fill light stays on from 18:00:01 to 05:59:59 of the next day.

 Advanced Settings: It is used to set the Color, Mirror, WDR (Wide Dynamic Range Imaging) mode

and its level, 3DNA (3-Dimensional Noise Reduction), Sharpness, and WB (White Balance) of the

camera. It cannot be modified by default.

 Color Mode: It is Normal by default.

 Mirror: Mirror mode is off by default.

 WDR Mode: It is WDR by default.

 WDR Level: It is Low by default.

 3DNR: It is Low by default.

 Sharpness: It is also referred to as clarity and is an indicator of uniform image clarity and

edge sharpness. If the sharpness is increased, the detailed contrast on the image plane is

higher, and the images are clearer. However, if the sharpness is too high, block lines can be

lined with white lines, and the images look shaded and glaring. The default value is 128.

 White Balance: It is used to set the white balance where colors are adapted to make the

images more natural. It is Auto by default.

 Exposure Control: The default mode cannot be modified.

 Shutter: The faster the shutter speed, the higher the brightness sensitivity, as well as the clarity

that the sound would be. The automatic shutter speed defaults to Higher.

 Aperture: The user can choose Manual or semi-automatic.

 Gamma: Gamma defaults to CURVE_2_0 and cannot be modified.

 Power Frequency: "Off", "50HZ" and "60HZ", the default is Off.

 Light Board Control: Set the light board mode and brightness.

 Mode: There are three modes, "Off", "Manual" and "Auto", the default is Auto.

LPRC300 User Manual

 Off: The light board is not controllable, and the light board is normally closed.

 Manual: The brightness of the light board can be adjusted by manually changing the

parameters, where the adjustable range is 1 to 100. The more the parameter value is, the

brighter the fill light will be, and the darker the image will become.

 Auto: The camera dynamically adjusts the light-board brightness by obtaining the current

image brightness, exposure, and gain, to achieve the optimal image accuracy with minimum

power.

 Brightness: When the light board mode is Manual, the brightness of the light board can be

controlled, and the adjustable range is 0 to 100.

Click [Save], after setting the parameters.
