11. FAQ
1. I do not have a network or internet connection. Can I still use the VWS2?
Yes, you can connect the VWS2 directly to your PC or notebook for remote control and video storage purposes.
2. Can I use ISDN to connect to the VWS2?
No ; the VWS2 can only be connected via ADSL or cable modem. It does not support ISDN connection.
However, a router that supports ISDN, RJ-45 and port forwarding, can be used with the VWS2.
3. What kind of frame rate can be expected?
This depends on the bandwidth and the average image size.
The formula to calculate the frame rate is: bandwidth / (8 x average image size) = number of images per second.
The average image size is: CIF: low=6Kb ; middle=9Kb ; high=12Kb ; VGA: low=24Kb ; middle=36Kb ; high=48Kb
Example: at a 512Kbs bandwidth and low CIF image quality (1 image = 6kb),
the frame rate is: 512 / (8x6) = 512 / 48 = 10.6 images/second.
