System Design Concept
2) CPU: Pentium4 3.6GHz, memory: 1GB, graphics board: Quadro FX1700
When using the VB-C60 with Resolution=340 x 240 and Quality=3:
Total frame rate:
JPEG image---Max. 260 fps
MPEG-4 video---Max. 210 fps
3) CPU: Pentium4 3.8GHz, memory: 1GB, graphics board: Quadro FX1700
When using the VB-C60 with Resolution=340 x 240 and Quality=3:
Total frame rate:
JPEG image---Max. 280 fps
MPEG-4 video---Max. 240 fps
Network Bandwidth Concept
You should consider the network bandwidth when recording video or viewing live video
from the network camera.
The network bandwidths should be calculated separately for recording and live viewing.
Example:
With one recording server (QVGA, 1 fps) and two live viewing servers (QVGA, 5 fps):
Bandwidth for recording
15 (KB/frame) x 1 (frame/sec) x 8 (bits) = 120 Kbps
Bandwidth for live viewing (per server)
15 (KB/frame) x 5 (frame/sec) x 8 (bits) = 600 Kbps
Therefore, required network bandwidth is calculated as follows:
120 Kbps x 1 + 600 Kbps x 2 = 1320 Kbps = Approx. 1.3 Mbps
Note that the line speed unit is bps (bits per second).
The total frame rate is calculated as: Number of Camera
Servers in the Viewer window x Frame rate. That means, with
10 Camera Servers and 10 fps frame rate, the total frame rate
is 100 fps.
Note that the total frame rate above varies depending on the
combination of the PC and graphics board. It is also affected
by other applications (e.g., anti-virus application) running on
the same PC.
When displaying MPEG-4 video in VGA, the maximum frame
rates are the one-forth of the above frame rates.
