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, 320 x 240 and 640 x 480.
■
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.
