8.3.7 Can’t access the IPCAM in the internet?
There are some reasons:
1 ActiveX controller is not installed correctly(see more details:5.1.4).
2 The port IPCAM used is blocked by Firewall or Anti-virus software. Please change a
port number and try again.
3 Port mapping is not success. You can do port mapping by two ways:
.Enter setting page of the router which IPCAM connect with to enable UPnP function.
Enter IPCAM “UPnP Settings” to enable UPnP and make sure the state is “UPnP
success”.
If your router has the Virtual Map function. Enter router setting page, add IPCAM‟s IP 
and port to the Virtual map list.
When use ADSL, the IP is dynamic. You should set DDNS(see more details 3.5.4 & 5.1.6)
and also make sure port mapping success.

IP camera tool can’t find the camera?
Except of the camera broken
1. Make sure the cable connector no problem, recommend connector
(AMP),it is with international standard. Another note, IPCAM’s data
transmission channel require higher than computer’s, so maybe the
computer can run normally but IPCAM can’t, Please press heavily when making the cable connector.
2. Confirm the power supply normally. First, check whether power indication
light turn on or not, If it is on,then check the yellow light on RJ45 Port
(power indication light) and green light (network indication light) are on or
not.If they are on,so power supply and cable runs normally.
3. Confirm all the firwall and antivirus software are close.The firewall often
block unrecognized data so if the firewall is running ,so maybe the IPCAM
TOOL can’t find the device.Suggest to close firewall and antivirus
software temporarily before searching.
