At first you can use our Installation Wizard to get the IP address of our products and connect to them and you can download it. If it doesn't work, you have to refer the following.

1. Your Network environment has DHCP service:
   • Please restore your camera to factory default settings first, and then use Installation Wizard to find its IP address.
2. Your Network environment does not have DHCP service:
   1. If you are using 2000, 3000, 6000 series and IP7137/IP7135/PT7137/PT7135 cameras, Please follow the under steps:
      1. Restore your camera to factory default settings.
      2. Connect your camera to your PC directly by a cross-over line directly. If you do not have a cross-over line, please refer to the following picture to connect your camera to PC:
      3. Set IP address of your PC to be 192.168.0.100
      4. Power on your camera.
      5. Open an Internet Explorer and type 192.168.0.99 to connect the camera.
   2. • If you are using our new product such as IP7138/IP7139/FD7131/VS7100… etc, no matter your network environment is what, you can always find the camera by Installation Wizard II with the IP address 169.254.x.y.
      • And then, please double click the camera found by Installation Wizard II or directly type the IP address to your Internet Explorer URL box to access your camera (you do not need to change your PC's IP address). After access your camera, please go to "Network" page to configure proper network settings.

Please try the following steps:

1. Restore the camera to factory default settings. Please refer to the link for how to restore this camera.
2. Connect your camera to the router, and use Installation Wizard to find the IP address of your camera in LAN. You can refer to the following picture to set up your equipments:
3. If the LAN IP address of your camera is 192.168.2.10, please forward some ports for 192.168.2.10 in the router side:
   • If your camera is 6000 series, please forward
     • HTTP port 80
     • UDP audio channel port 5002
     • UDP video channel port 5003
   • If your camera is 7000 series, please forward
     • HTTP port 80
     • RTSP port 554
     • RTP port for audio 5556
     • RTCP port for audio 5557
     • RTP port for video 5558
     • RTCP port for video 5559
   • If your camera is 3000 series camera, please forward
     • HTTP port 80
     • Control channel port 5001
     • Video channel port 5003
     • Audio channel port 5002
4. Find the WAN IP address of your router, for example, if the WAN IP is 203.67.124.123, and then please open an IE and input URL http://203.67.124.123 to connect your camera via internet. Please refer to the file BELKIN router for 7000 or BELKIN router for 6000 to configure your router.

Reason: You didn't forward the ports of network page of the camera on your router. Solution: You have to forward your ports for your camera on your router. The following example is the default port numbers of our products.

• If the model of the camera is 6000series,the numbers you have to forward as below;
  • HTTP port 80
  • UDP audio channel port 5002
  • UDP video channel port 5003
• If the model of the camera is 7000series,the numbers you have to forward as below;
  • HTTP port 80
  • RTSP port 554
  • RTP port for audio 5556
  • RTP port for video 5558
• If the model of the camera is 3000series,the numbers you have to forward as below;
  • HTTP port 80
  • Control channel port 5001
  • Video channel port 5003
  • Audio channel port 5002

If you don't want to forward port on the router manually, you can enable the "UPnP port forwarding" in the network page of the camera to forward the port on the router directly. (Note that your router has to have "UPnP" function as well)

"Port Forwarding" function will detect and map the port numbers of Network page with the router to see if they are already used by other devices or not.

If the camera detects that there are no conflicts with the ports in the router, then it will forward the ports in the router directly.

If the camera detects that the ports have been used for other devices, in the network page, it will show "red prompt" suggest which port number you have to change to (for 3000, 6000 series and IP7137/IP7135/PT7137/PT7135 cameras) or it will automatically change the port number.

After you changed the port numbers, you can access the camera by using http://<WAN IP of router> : <http port number of the camera>

You have to check the following settings on your camera.

1. Please make sure that your camera is 7000 series camera.
2. The view mode is set to "mobile viewing" on the Audio and Video page.
   (video size is 176x144/176x120,Max frame rate is 5,Constant bit rate is 40kbps,audio type is GSM-AMR)
3. You have to disable RTSP authentication on the Network page.
4. IYou have to forward the HTTP port 80, RTSP port 554,RTP port for audio 5556,RTCP port for audio 5557,RTP port for video 5558,RTCP port for video 5559 of your camera on the router.
5. You can access the camera with rtsp://<public IP address of the camera>/live.sdp

The following steps are the correct procedures.

1. Set up your camera in the LAN or connect to your PC by a cross-over line
2. Configure the valid settings of the SMTP server or FTP server on Email and FTP page.
3. Configure the valid settings (user name) of PPPoE connection on network page.
4. Click save , the camera will connect to internet via PPPoE after it booted.
5. The Email or FTP will receive a system log file contains the IP address of the camera.
6. Check the system log and find the IP address of this camera.
7. You can connect to the camera with the IP address.

As you know, in our products you can select constant (fixed) bit rate to control the amount of the video stream data per second. If you select fixed quality, the amount of video stream data would be floating depending on the motion in the video. (From 1Kbps~300Mbps) Fixed quality uses a higher bit rate during fast motion scenes and a lower bit rate during slow motion scenes. Constant (fixed) bit rate means a constant bit rate must be used. The available bandwidth is fixed, like videoconferencing delivered on channels with fixed bandwidth. So you may lose some images during fast motion scenes.

The following steps are the correct procedures.

• 2000 series: no audio, need HTTP port, default is 80.
• 3000 series: audio/video, need audio/video/control/HTTP port, default is 5001/5002/5003/80.
• 6000 series: audio/video, only HTTP port is needed (default is 80), but also can use UDP mode therefore 5002/5003.
• 7000 series: audio/video/rtsp, need HTTP/RTSP port number, default is 80/554.

Regarding the 6000series,3000series,and 2000series, their default IP address is 192.168.0.99. If you have three our products, their IP address will be 192.168.0.99,192.168.0.100,192.168.0.101.Regarding the 7000series and our new models, their default IP address is 169.254.X.X that can be connected by your computer in any network address.

The following table is for your reference only. It may vary from different environments. Test approach: Play an action movie (name: Matrix) at 30FPS and record for 10 minutes.

Most office has setup firewall to filter packets other than 80 port, the default HTTP port, and the public IP address is shared by multiple workstations. That's why there are many methods used in VoIP, instant messenger, file exchanger to bypass this rule for communication.

Our 3000 series products need one port for video, one port for audio and the other port to control the handshake and synchronization. If users can only use HTTP mode, there is video only transmitted via HTTP. To utilize HTTP port for general web data and such heavy multimedia content may make network administrator unhappy. They cannot separate either one for best management. However, users have to solve multiple servers located inside the firewall. That needs NAT support. NAT should have port mapping for different private IP address to one public IP address.

I would like to talk about what is multicast before talk about how to use Multicast with VIVOTEK camera. Multicast is a one-to-many transmission technology. It's an efficient way to deliver a single stream of live data to, in theory, unlimited number recipients at the same time. Instead of sending 1000 streams of information to 1000 users, it sends only one stream of audio, video, or data. The single stream will then be delivered to unlimited number of users via dedicated multicast routers dispersed throughout the Internet.

So if you enable multicast item on Network page of the camera, which means the camera support multicast. Anyone in the same local area network can choose to use multicast method to link to the camera. You can just go to the client settings page and choose multicast for protocol options.

Here is the directions about how to use Multicast.

1. Please go to the Network page of your camera.
2. At the client's site, please go to the client settings.

After that, the IE is viewing the camera via Multicast. Besides, the Multicast is more suitable to work in LAN than Internet because the following information.

Multicast is a method of forwarding IP datagrams to a group of interested receivers. But multicast is hardly to be used over the internet. It needs to have all routers that route to the camrea over the internet support multicast function. So we do not suggest users to open ports for multicast.
