bandwidth selection, select Fixed quality and select a video quality level. This setting will utilize more bandwidth

to send the maximum frames when images change drastically.

These settings are to optimize your camera performance with your available bandwidth.

Select a fixed bandwidth for your camera operation. This option allows the user to select a custom frame rate

suitable for the bandwidth and the storage space.

Selecting fixed quality will roughly select your image quality and will not be as accurate as setting by bit rate.

This setting is easier to use when image quality does not have to be precise. Below is a typical file size after

1 minute of recording at 30fps (frames per second). This is only an average measurement; your file size may

differ due to lighting, black/white or color setting, and frame rate.

Vertically rotate the video.

Horizontally rotate the video. Check both flip and mirror if the DCS-5220 is to be installed upside down.

White Balance is related to the color temperature. Color temperature is a way of measuring the quality of a

light source. It is based on the ratio of the amount of blue light to the amount of red light, and the green light

is ignored. The unit for measuring this ratio is in degree Kelvin (K). A light with higher color temperature (i.e.,

larger Kelvin value) has “more” blue lights than a light with lower color temperature. The default setting for the

camera is “Auto”.

Select this option to display the current date and time on the video image. All the snapshots and video data will

have the date and time locate on the corner of the picture.

Section ² - Configuration

“Best performance” means the image refresh rate should be the fastest possible and the video quality should be the

best possible at the lowest network bandwidth possible. Three factors, Maximum frame rate, Fix bit rate, and Fix quality

in the Video Configuration page, are related to performance.

Recording settings for real-time motion images

To achieve a real-time visual effect, the network bandwidth should be large enough to transmit 20 image frames

per second (fps) or more. If you are on a broadband network over 1 Mbps, you can set Fix bit Rate to 1000Kbps or

1200Kbps, or set Fix quality to achieve the maximum frames. The maximum frame rate is 25 in 50Hz system and 30 in

60Hz system. If your network bandwidth is more than 384Kbps, you can adjust Fix bit rate according to your bandwidth

and set the maximum frame rate of 25 to 30.

If the images vary dramatically in your environment, you may slow down the maximum frame rate to 20 to decrease

the transmitted data for better video quality. Since the human eye could not easily differentiate between 20 and 25

or 30 frames per second, the slower frame rate will not be noticed. If your network bandwidth is below 384 Kbps, you

should adjust the bit rate according to your bandwidth and experiment to allow for the best frame rate that can be

achieved. The faster frame rate in a slow network will blur the images. You may also try to choose 320x240 in size

option for better images or 640x480 for larger image size. Because the network has burst constraints and everyone’s

environment is not the same, any poor connection will impair normal performance.

Recording settings for clear identification for each image

To have the best video quality, you should set Fix quality to detailed or excellent and tune the Maximum frame rate to

suit

your network bandwidth. If you get some broken pictures in a slow network, you can set TCP protocol in Connection

type for a more accurate transmission but the received images may have a lag. Note that any slow connection with

multiple users will impair performance.

Recording settings to compromise between real-time and clear images

If you have a broadband network, set Fix quality to Good image quality, or higher, instead of setting the Bit rate.

Otherwise, fix the bit rate according to your actual network speed and set the frame rate to 30. If the image quality is

low, select a lower frame rate above 15. If the image quality is still not improved, select a lower bit rate.

From this screen you can fine tune the video image.

Image Brightness, Contrast, Saturation and Hue are all adjustable in the same manner. For each video compensation,

you can set from among eleven levels ranged from -5 to +5.

The default setting is zero for each adjustment.

You may use the

Motion Detection

Click the Motion Detection button from the Configuration screen to enable the motion detection function of the

DCS-5220 Internet Camera.

Check this option to turn on the motion

detection.

area of the image window. Up to 3

added.

The name of the motion detection

window.

Adjusting the sensitivity allows you to

set the “amount of motion” required to

trigger motion detection. If you want

to detect most or all movement, use a

high sensitivity. If you want to ignore

smaller amounts of movement, use a

low sensitivity.

Adjusting the percentage allows you to set a requirement on how much of the motion window

must be filled by movement. Example: If you set this to 50%, then the selected window must be

half filled by a moving object before it triggers motion detection.

A green bar means the image variation is under the monitoring level, and no motion detection alert is triggered. A red

bar means the image variation is over the monitoring level and a motion detected alert is triggered. When the bar goes

red, the window that the motion is detected in will also be outlined in red (

Note:

remember that you can have up to 3

windows selected for motion detection

). You can return to the DCS-5220 Home Page and the monitored window will

not be visible, but the red frame will show on the home page when motion is detected.

To display motion detection, a graphic bar will rise or fall depending on the image variation.
