Video input selection

Switch the video source among up to four cameras connected to Video Server. When

clicking on the quad display button, a special quad display of all video inputs is available

for simultaneous monitoring. The picture refresh rate of quad display is slower than the

single input because it takes time to capture the valid image after changing the video

source. The actually appearing buttons depend on the system settings.

Video quality selection

It allows users to adjust the video quality for speed or smoothness. The performance is

also subject to the network bandwidth and the number of users. Five options are

available to be chosen from “Medium” to “Excellent”. “Medium” quality means the

picture has the quickest refresh rate but the worst image quality and “Excellent” quality

means the picture has the slowest refresh rate but the best image quality.

Video size selection

It allows users to adjust the image size with consideration of bandwidth and image

resolution. Five options are available including “Half”, “Half×2”, “Standard”,

“Standard×2” and “Double”. “Half×2” consumes the same bandwidth as “Half” but

has the same size with “Standard”. Of course the visual effect is worse than “Standard”.

“Standard×2” compared to “Double” is similar to the case. “Half×2” is especially suits

in the low bandwidth environment like a dial-up network. To fit into the small image area,

timestamp will be skipped in “Half” and “Half×2” modes.

While in the quad display mode, “Half” means the image is composed of half size image

of each channel. “Standard (fast)” will have higher frame rate and “Standard (clear)”

will have higher resolution image.

System configuration

There is a button or text link under video buttons for system configuration that only

appears in administrators’ main page.

External digital output control

There may be two remote control buttons for each digital output on the main page. If

there are external devices attached to digital outputs, administrators or permitted users
