How to view IP camera via Internet








IP camera is a digital camera and based on internet. Of course, we can view it on the internet. We take the following network topology as an example.

WN-350R connects to Internet and gets two IP addresses, LAN IP and WAN IP.
On the LAN, each device will get one IP address from WN-350R so IP camera, OD-325HD, gets an IP address, 192.168.0.99 and your PC on the LAN gets an IP address, 192.168.0.100
If you would like to view IP camera on your PC on the LAN, just open browser and then, type “192.168.0.99.”
You will see Web User Interface to ask to enter account and password.


Default value in AirLive IP camera
Account: admin
Password: airlive
After enter a correct account and password, you can do the live view on your PC.

If you would like to view IP camera on the WAN, we need to set up WN-350R.
Enter WN-350R Web UI to select “Virtual Server” function.
Setting Local IP Camera (Private IP: 192.168.0.99) private port: 80 to Public
port: 33001.
Don’t forget to click APPLY button to save the configuration.
Now you can just type http://59.115.99.27:33001 on your browser and enter your account and password to do the live view no matter where you are.

How to make wireless connection in a far distance

  1. Please prepare GPS, compass, Hi-Power Binocular and Walkie talkie 
  2. Set up One Wireless Outdoor CPE as AP mode and the other Wireless Outdoor CPE as client mode. 
  3. Use Google Earth to mark a line between two APs. It can be helpful to adjust the direction and alignment. 


  4. Print the MAP and take the MAP to the point . 
  5. Please use the compass to find the north and let the MAP north in direction of north. 
  6. Please adjust CPE to face another point. Choose a landmark to be a goal if you can’t see the goal directly. Please make sure you have a clear line of sight between two APs. At least 60% of First Fresnel Zone must be cleared for acceptable performance. 
  7. 2 people in a group. One does antenna alignment. The other reports the RSSI values until the antenna alignment is perfect. 
  8. Use just enough output power. Excessive output power will create serious interference for everyone and reduce the performance.
