14.1.2.3 Network Address

This is the IP Address of the camera on the local boat network. If your network

includes a DNS server, this may be entered as a name.

14.1.2.4 Camera No.

When setting up an analog camera attached to the quad video server, the

channel number is chosen from a drop down list, in addition to the name and IP

address.

14.1.2.5 Mirror Image

The image will be flipped to produce a mirror image is this box is checked.

14.1.2.6 Compression, Frame Rate, and Resolution

There is a tradeoff between the quality of the picture displayed and the

bandwidth or data rate required to support that quality. On the local network of

the boat this is probably not important, but when transmitting the picture over the

internet you may wish to compromise the quality to save bandwidth.

Compression is the amount of pre-processing that can be done to each image

before transmitting to squash the image into a smaller size. Compression values

less than about 80% produce very little distortion in the image and can result in

significant savings in bandwidth It does require more processing power to do the

compression and then uncompress in N2KView.

Frame Rate is the number of frames that are transmitted every second. The

higher the frame rate, the smoother the video. Doubling the frame rate requires

twice the bandwidth.

Resolution is the amount of pixels (or dots) that make up the picture. The first

number is the number of dots across the screen, the second is the number from

top to bottom. The larger the resolution, the more detail can be seen in the

picture and the greater the bandwidth requirement.
