Maximum frame rate
This limits the maximal refresh frame rate per second
.
Set the frame rate higher for a
smoother video quality.
If the power line frequency is set to 50Hz, the frame rates are selectable at the following
rates: 1fps, 2fps, 3fps, 5fps, 8fps, 10fps, 15fps, 20fps and 25fps. If the power line frequency
is set to 60Hz, the frame rates are selectable at the following rates: 1fps, 2fps, 3fps, 5fps,
8fps, 10fps, 15fps, 20fps, 25fps and 30fps.

Intra frame period
Determine how often to plant an I frame
.
The shorter the duration, the more likely you will get
a better video quality, but at the cost of higher network bandwidth consumption
.
Select the
intra frame period from the following duration: 1/4 second, 1/2 second, 1 second, 2 seconds,
3 seconds and 4 seconds.
■
Video quality
A complex scene generally produces larger file size, meaning that higher bandwidth will be
needed for data transmission. Therefore, if Constant bit rate is selected, the bandwidth
utilization is fixed at a selected level, resulting in mutable video quality performances
.
The bit
rates are selectable at the following rates: 20Kbps, 30Kbps, 40Kbps, 50Kbps, 64Kbps,
128Kbps, 256Kbps, 512Kbps, 768Kbps, 1Mbps, 2Mbps, 3Mbps and 4Mbps.
On the other hand, if Fixed quality is selected, all frames are transmitted with the same
quality; bandwidth utilization is therefore unpredictable. The video qualities are selectable at
the following settings: Medium, Standard, Good, Detailed and Excellent.
If
JPEG
mode is selected, the Network Camera continuously sends JPEG images to the clients,
producing dynamic effects similar to movies. Every single JPEG image transmitted guarantees
the same image quality, which in turn comes at the expense of variable bandwidth usage
.
And
because the media contents are a combination of JPEG images, no audio data is transmitted
to the clients.
■
Frame size
Select the video size. Note that a larger frame size takes up more bandwidth. The frame
sizes are
selectable in the following resolutions: 176 x 144, 352 x 240 and 720 x 480.

Disable IR LED:
If you don’t want to let others know that the network camera is on, you can select this option to
turn off the LED illuminators. This will prevent the Network Camera’s operation from being
noticed.
