A/V Settings

Basic



Audio: Enables and Disables the Audio stream

Resolution : There are 4 different resolutions to choose from:
D1 :720x480 NTSC/720x576 PAL
VGA : 640x480
SIF :352x240 NTSC/352x288 PAL
QSIF: 176x112 NTSC/176x144 PAL

Frame Rate: The frame rate can be set between 1-30fps.

Encoder Format: Format can be selected for MPEG4 or MJPEG

Bitrate: There are 6 different constant bitrates to choose from between 64Kbps and 1Mbps, and 4 variable bitrates between Low and High quality.
If you are planning on using the device on an Internet connection It is recommended that you select a constant bitrate that corresponds to your actual upload speed. It is also recommended that you modify the frame rate and resolution as well, otherwise the video stream may become blocky or otherwise distorted. The recommended values are as follows:
64Kbps: <10 fps QSIF (<5 fps SIF)
128Kbps: <15/12 fps QSIF (<10 fps SIF)
256Kbps: <10 fps SIF (<5 fps VGA, 30/25 fps qsif)
512Kbps: <15/12 fps SIF (<10 fps D1/VGA)
768Kbps: <10 fps D1/VGA (30/25 fps SIF)
1Mbps: <15/12 fps D1/VGA
For higher frame rate use a variable bitrate instead. However, this is not recommended for Internet use.
For Good Quality, full resolution (D1), and full frame rate (30/25 fps) it is recommended that not more than 4 users connect simultaneously.
For High Quality, full resolution (D1), and full frame rate (30/25 fps) it is recommended that not more than 2 users connect simultaneously.

Interlace mode: There are two modes available: Interlaced or Progressive.
Interlaced mode is a storage mode. An interlaced video stream contains fields rather than frames, with each field containing half of the lines of a frame.
A progressive video stream consists of only full frames.
Interlaced video streams can bring a lower bitrate but may cause lower quality.

TV Standard Select the TV mode according to your needs, options are NTSC, PAL and SECAM

MPEG Sequence mode: There are 2 different modes available:
I-frames only
I-frames and P-frames
P-frames, or predictive frames, are predicted based on prior P or I-frames plus some additional data. They have a much higher compression ratio than I-frames.
I-frame only mode has very little compression resulting in large file sizes.
I-frame and P-frame mode offers relatively good compression with medium file sizes. Although this requires more work on the host PC to decode the video.

GOP Size: GOP stands for Group Of Pictures. It defines the number of frames from one I-frame to the next. Since an I-frame uses very little compression, while P/B frames use much higher compression, a larger GOP size, results in smaller file sizes. For more information about I/P/B-frames, see below.
For MPEG-4 there is no maximum GOP size defined. It can be as low as 1 V just an I-frame - or into the thousands. However, as the GOP size increases, the compression increases, and therefore the more likelihood of errors. A higher GOP size also results in higher buffering times.
For DVDs the GOP size is 15. The default on the MVS is set to 60, which offers fair compression with a low likelihood of errors.
Peak Bitrate - This is used to set a maximum bitrate that can be achieved. This is useful for setting bitrates between the values that are available from the Video Encoder bitrate list.

Image Adjustment

Video Server P-1401

Contrast, brightness, Hue and Saturation can be adjusted.
Values run from -100 through 100.
Rotation: Select the Digital Rotaion for the camera: 1- 90 Degrees; 2- 180 Degress; 3- 270 Degrees; 4 - 360 Degrees.
Load Default: sets the image adjustments back to factory default.

IP Camera P-400



Contrast, brightness, Hue and Saturation can be adjusted.
Values run from -100 through 100.
Rotation: Select the Digital Rotaion for the camera: 1- 90 Degrees; 2- 180 Degress; 3- 270 Degrees; 4 - 360 Degrees.
Load Default: sets the image adjustments back to factory default.
Electronic Shutter: The shutter will automatically adjust the exposure of the built-in CCD to get the better illumination when set to Open.

Auto Gain Control: Normally “off” with maximum 10db gain, “on” will increase to maximum 24db. It's useful to increase sensitivity in low illumination environments (set to “on”), but more gain will produce more noise.

Note: When using Lens with DC-Driver Auto IRIS capabilities in low light conditions, you should disable AES to get optimal lens performance. In strong light conditions it should be enabled to prevent color loss.

PTZ Settings:

Change the serial port mode and configure the serial port settings. Revise your PTZ device for the type of data require.

External Sources


The Video Source feature allows the user to set additional channels for the device.
Information such as
IP address: Enter a valid IP address from an IP Camera or Video Server
Port: Enter the port number used for the IP address to display the video
Video Type: select MJPEG and MPEG4.
Rotation: Rotation degrees run from 0 to 270 degrees for a permanent digital position.
Name: Enter a name for the device
Video Channel: 1~4. Video channels from 2 to 4 are applicable for Video Servers.
Username/Password: Enter the respective Username and Password if applicable. If no user has been set for the device, the default value should be root and pass respectively.
PTZ Model: Enter a PTZ model in case the device is a PTZ model or controls a PTZ
RTSP Port: Enter a RTSP Port used for streaming in case the external source is an MPEG4 device
Product Type: Select from MJPEG or MPEG4 Video Servers or IP Cameras. Please refer to the original document of the device for a better description.

 

On Screen Display

The on-screen display is used to identify a video source from the video stream.
On Screen Display-Click enabled to use the on-screen display.
OSD Text- Enter a description of the video source.
OSD Coordinate X/Y - Select the X/Y coordinates. The default is the top left-hand side.
Display Font Grey Level - Define the shade of gray used for the font. The level goes from 0 to 255.
