Question about modification usb - cat 5 ftp for web camera

[weather1967]

I would like to make a question if somebody for you have try to replace the usb cable with cat 5 ftp shield for to have more distance signal for usb web camera picture .
Because i have observe after 9 meters away with usb cable ,camera lost the signal picture with pc ,and after 14 meters away it lost the signal picture with pc ,if i use hub usb with external power .
I see the usb cable it is shield like cat 5 ftp ,but the inside cables it is smaller and many-ply and not one-ply like cat 5 ftp ,and one-ply cables it is better for long distances.
I wonder if this way we can to have signal picture web camera-pc for 20 or 30 meters away

You need an active hub with seperat ac every 5 meters minimum. But remember that more than 30 meters is not possible cause the time the signal needs on his way is then too long.

I have here 15 Meters USB with two active hub and it works.

The maximun defined length of an unamplified USB-Cable ist 5 m.
You can entend this by couppling several amplified USB-cable together, but all in all, the maximum lenght ist 30 meters.

When you want to extent USB-cables, you can use special USB-extenders, that will use a CAT5 cable between the special extender-boxes.

Here is a german link to such an extender: http://www.pearl.de/a-PX3148-1413.shtml
(this extender is only USB-1.1)

here is an english link to such an extender (also only USB-1.1):

Ich kenne das Gerät von Pearl frage mich nur ob es für eine Webcam reicht? Man will ja doch anständige Bilder haben.

Gut die alten USB Cams lieferten schon entsprechende Bilder aber die neuen mit USB 2 denke ich werden mit dem Adapter nicht zufrieden sein.

Hat wer Erfahrung?
