– Video quality:
A complex scene generally produces larger file sizes, meaning that higher
bandwidth will be needed for data transmission. Therefore, if Constant bit rate
is selected, the bandwidth utilization is fixed at the selected level, resulting in
variable video quality performances. The bit rates are selectable at the following
rates: 20 Kbps, 30 Kbps, 40 Kbps, 50 Kbps, 64 Kbps, 128 Kbps, 256 Kbps,
512 Kbps, 768 Kbps, 1 Mbps, 1.5 Mbps, 2 Mbps, 3 Mbps and 4 Mbps.
On the other hand, if Fixed quality is selected, all images are transmitted with
the same quality; bandwidth utilization is therefore unpredictable. The following
video quality settings are selectable: 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. As the media contents are a
combination of JPEG images, no audio data is transmitted to the clients.
– Maximum frame rate
This limits the maximum frame refresh rate per second. Set the image rate
higher for a smoother video quality.
If the power line frequency is set to 50 Hz, the image rates are selectable at the
following rates: 1 ips, 2 ips, 3 ips, 5 ips, 8 ips, 10 ips, 15 ips, 20 ips and 25 ips. If
the power line frequency is set to 60 Hz, the image rates are selectable at the
following rates: 1 ips, 2 ips, 3 ips, 5 ips, 8 ips, 10 ips, 15 ips, 20 ips, 25 ips and
30 ips.

The following video quality settings are selectable: Medium, Standard, Good,
