–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.
–Video quality:
The following video quality settings are selectable: Medium, Standard, Good, Detailed and Excellent.
