5. Other Q&As
What’s the valid transmission distance of common 5-kind twisted-pair cables?
The standard distance is 100m. With the help of Hub or switch, the distance can be
increased to 480m.
How long of a USB extension cable can a cradle-head webcam support?
The standard length is below 5m. For special USB extension cables, the length is up to
20m (i.e. the distance between two webcams is 40m). However, such special USB cables
are hard to buy and are expensive (maybe more expensive then a server), so that it is not
feasible.
Can QIPCAM be put outdoors?
QIPCAM is designed for indoors use mainly. If being used outdoors, the effect may be
slightly less satisfactory, and you need to add a protection shield.
Why can't I view images via the Internet while I can view them within the LAN?
You need to map the port "80” in “virtual server” or “forward rules” of the router to the LAN
IP of QIPCAM. Port 80 corresponds to the TCP protocol.
My QIPCAM is not placed behind a firewall. Why DDNS cannot be realized?
Please make sure whether the dynamic domain name server is correct and whether the IP
address of your router is consistent with DDNS. If the two settings are both correct, please
modify the DNS of QIPCAM to the DNS address of your local Telecom or Netcom.
How to apply for and set up a dynamic domain name?
Take 3322.org dynamic domain names as an example. In the site
http://*.net
, log on
using your registered username and password. Then, as shown in the figure, click
“domain management” to enter it. Click “dynamic DNS” on the left side to show a pull
down menu. Then, click “Create” to create your own sub domain name. Do not modify
other settings, and then click OK to make the domain name take effect. As shown in the
figure, add the applied domain name to the dynamic domain name option of QIPCAM. As
shown in the figure, you can also directly add it to the network setting in the Web interface
of QIPCAM.
