1. How to run NetCamCenter 3.0 on Windows Server 2012.

To run NetCamCenter 3.0 on Windows Server 2012, please follow the steps below.
  • Install the Media Foundation and Desktop Experience
  • Restart the Server
  • Launch Server Manager from the taskbar.
  • On the top right menu click Manage and point the cursor to Add roles and features
  • Click Next. Select the server you wish to configure.
  • select Features on the left node and scroll down to User Interfaces and Infrastructure.




  • Expand this feature and select Desktop Experience. When you are prompted for installing required features, click Add Features




  • Click Next and follow the wizard to completion, which will require a restart of the server.


2. I'm unable to connect to my RTSP camera.

Here're the check list:
  • Make sure RTSP port, path are correct.
  • For cameras on local area network, always try RTSP-UDP first. If the camera is at remote location, then try RTSP-TCP or RTSP-HTTP first. The reason is, about all RTSP cameras supports RTSP-UDP, but not all RTSP cameras support RTSP-TCP/RTSP-HTTP. Also, for LAN, UDP is a better protocol choice. For going thru Internet/Firewall/Router, TCP/HTTP are easier to setup.
  • When using RTSP-HTTP, some cameras use port other than the web server port. So you have to assign RTSP-HTTP port properly by not using camera's web server port.


3. I'm unable to connect to my ONVIF camera.

ONVIF camera transmits video based on RTSP protocol. You can setup your camera as ONVIF camera, make sure you have inputed address, port number, username, password correctly, click on ONVIF button, NetCamCenter shall pull camera info. Please see #2 and make sure you selected correct protocol. Note at this moment, ONVIF isn't as mature as RTSP, not all ONVIF cameras respond to ONVIF commands correctly. You may want to consider selecting the camera as RTSP instead.


4. The video window indicates connected, but I don't see video (video window is black).


For performance, NetCamCenter utilize DirectX 9 to render video. Some display card may not work properly with DirectX. On Video Window, Setup, Misc tab, uncheck Render Video by DirectX 9, this shall fix the problem. If you need to monitor live video but having this issue, you should consider using a display card that can do DirectX 9 video properly.

Please note you'll also see this as free edition does not support MPEG4 codec yet.

5. The video sometimes becomes blocky or blurry.


This could be one or a mix of the followings:
  • Your system is running out of resources for hardware acceleration. On video window, click on Setup, Misc tab, disable "hardware H264 decoding" for some cameras. You may also need to disable "GPU acceleration" and "Render video by DirectX 9" for some cameras too. Note disable acceleration will add more CPU loading.
  • Your system is low on memory.
  • The system isn't fast enough. On video window, Setup, Misc tab, reduce rendering frame rate. E.g. drop from 30 frames/sec to 10 frames/sec.
  • Networking issue (e.g. not enough bandwidth hence data packets are being dropped), especially if you are using wireless network.

6. How do I view NetCamCenter video streams over the Internet?

  • For NetCamCenter CamNebula Free Edition, the only option is thru CamNebula service. For CamNebula editions, this is fairly easy as you only need to go to each camera Setup/Cloud/Enable CamNebula. For remote viewing the video streams, install the required desktop plugins or mobile apps. Note you should use CamNebula Viewer app instead of NetCamCenter Viewer app.

  • For NetCamCenter Basic and Professional, besides thru CamNebula, you can also setup the built-in web and RTSP server for remote viewing. Video streams are served direct from your PC. This requires a good understanding of IP network and configuring router properly. This option is not recommended for average users not only because it needs more know how, a misconfigured router will also open your network for outside attacks.

    To enable no-plugin MJPEG viewing thru web server, on CamCenter Setup, Server, Enable web server.

    To enable streaming with RTSP server, on CamCenter Setup, Server, Enable RTSP server. For RTSP stream 2 (mobile stream), you'll also need to enable RTSP streaming on each camera, to do so, on camera Setup, Streams, Enable mobile RTSP stream. For cameras with H264 encoding, you can view both stream 1 and stream 2 with RTSP viewers (e.g. Apple QuickTime, NetCamCenter, VLC ...etc.) For other cameras,  only stream 2 is available when you use RTSP streaming. Stream 1 offers best quality.

    For remote viewing, you'll need desktop plugs or mobile apps. For mobile apps, you'll need NetCamCenter Viewer.

    Please note audio is only available when viewing with RTSP streaming.

7. How do I setup remote viewing for NetCamCenter Basic/Professional?


NetCamCenter Basic/Professional (includes CamNebula Basic/Professional Editions) provide web server and RTSP server for remote viewing, plus CamNebula integration.
  • For web server, on CamCenter, Setup, Server, Enable web server. 

  • For RTSP, on CamCenter, Setup, Server, Enable both web and RTSP Server. NetCamCenter provides dual RTSP streams. 1st stream is only available for H264 IP cameras. 2nd (mobile) stream can be used for all supported cameras. To enable 2nd stream, on each camera Setup, Streams, enable mobile RTSP stream. Adjust frame size based on your mobile devices. You can adjust 2nd stream bit rate at Setup/Cloud, Remote Recording bit rate.

  • Assign port numbers properly based on your network configuration. It is recommended you check Authorization required option. For viewing with RTSP, you'll need QuickTime plugin for desktop and install mobile apps. RTSP provides you much better video quality compare to thru web server.

8. Which ports should be open for NetCamCenter?


Click Setup on CamCenter. On the Server tab, you shall see the web server port number there. If RTSP server is also enabled, you will need to open RTSP port as well.



To check your Windows Firewall settings,

  1. Clicking the Start button, and then clicking Control Panel. In the search box, type firewall, and then click Windows Firewall.

  2. In the left pane, click Allow a program or feature through Windows Firewall.

    check Windows Filewall setting

  3. In the Allowed apps and features list, Check NetCamCenter Camera Process, and NetCamCenter Media Server Process.

    check Windows Filewall setting


9. How do I move my data folder?

Please close NetCamCenter, go to download page, download and run "Tool for NetCamCenter".
The tool allows you to move primary data folder. It is recommended you use internal hard drive as primary folder.

Note the tool only help you move primary data folder (camera settings), it does not move your existing videos to the new folder. Some camera settings are stored in Windows registry. NCCBF does not touch those registry settings.

For Professional version, you can assign each camera to different folder. Again internal hard drive is recommended. If you want to use NAS or USB hard drive, please make sure their performance meets the requirements. The hard drive must be able to write at least as fast as your cameras generate data.

11. What're the recommended hardware and OS for NetCamCenter??

For Professional, we recommend running the software under Windows 7/8/10 with Intel core processors (3rd gen or later). For Basic version, Windows 7/8/10, both Intel or AMD CPUs are fine. Faster is always better.

Video data are huge. Hence, to make it work, often the hardware and software have to arrange a special channel for video. That's why you have AGP, PCIe x16, DirectX (DirectX means direct access to video card, sound card ...etc), GPU ...etc espeicially desined for video accelleration. On the other hand, server OS and hardware don't like complicate hardware and application software to have direct access to hardware. (more stable) That's why on server OS, all multimedia related features are not pre-installed. (less complixity means less chance of failure) So fundamentally, the 2 contradic each other.

Running NetCamCenter, or software simliar to NetCamCenter under virtualization is a bad idea as you'll have very poor performance. Only use server OS if you must use a rackmount server, but unable to find a vendor to provide you one with Windows 7/8/10. When running NetCamCenter under such environment with remote desktop, you may want to uncheck Setup/Restore all video windows when CamCenter window is restored. Only activate one video at a time, make the window size as small as possible. You can minimize (but DO NOT CLOSE) all video windows once you complete setup. By doing this you can avoid RDP runing high CPU usage on compressing all video channels.

Some users may also want to use old machines, or purchase used servers to run video surveillance. Often when customers asked about this, the machines mentioned are more than 4 years old. Please beaware a 3.0 GHz 5 year ago and a 3.0 GHz CPU perform quite differently. CPU clock alone can no longer be used to estimate the performance. Also, the newer machines also have much faster I/O, which often ignored but is an important factor for DVR/NVR.

It is ok to use such machines for testing, but it is not recommended for production use. Video data are huge and needs lots of real time processing power, by doing so, you are essentially assigning the heavy loading task that needs to be run 24/7 to a machine that is near end of life and not qualified for the job. For home and small business, to cut cost, you may want to instead use a mid-high end PC with dual monitors to run both your typical desktop tasks and NetCamCenter Professional. (Please make sure the PC has enough power to run all the jobs.) Newer CPU not only is much faster, the new Intel core processors also provides GPU to help video applications. They are also more energy efficient.


12. Tips for runnign NetCamCenter on server or thru Remote Desktop.

When running NetCamCenter under such environment with remote desktop, you may want to uncheck Setup/Restore all video windows when CamCenter window is restored. Only activate one video at a time, make the window size as small as possible. You can minimize (but DO NOT CLOSE) all video windows once you complete setup. By doing this you can avoid RDP runing high CPU usage on compressing all video channels.

13. I'm unable to view live video thru CamNebula.

First make sure you have the feature enabled by going to video window, Setup, Cloud, Enable CamNebula. (default is off)

If you are not using CamNebula Editions, you probably entered your NetCamCenter built-in web server username/password. The username, camera tokens should be the ones provided by CamNebula service, not something you created, or from other services (e.g. Google, Facebook ...etc). Please see and follow the screen shots on how to copy and paste your username and camera tokens into NetCamCenter. Also see CamNebula FAQ.

If you still have trouble setting it up, we recommend you use CamNebula Editions (e.g. Free Edition). CamNebula Editions will automatically config this part for you based on your subscription. You can open the dialog box and see how this is configured, use it as an example, and switch to NetCamCenter standalone version if you wish.

14. I can't start web server, error message "component is missing".

If you see this message after installing CamNebula Edition, re-install with standalone version. By default, the standalone version and CamNebula Editions are installed to different folders. CamNebula Free Edition does not contain components like built-in web server, media server ...etc. You'll see this message when you try to run standalone version after installing CamNebula Free Edition.


20. How do I configure email program to send alarm email on Windows 7?

If SMTP setting is not configured, you will see the following message when NetCamCenter tries to send an alarm email.



To install the email client,
  1. Click Control Panel.
  2. Click All Control Panel Items.
  3. Click Default Programs.
  4. Click Windows Live Mail.
  5. Click Set this program as default. Click OK.

21. Can I run Microsoft Security Essentials with NetCamCenter?

Yes, you can run Microsoft Security Essentials with NetCamCenter. Please refer to the steps below to configure Microsoft Security Essentials. (Note: you may want to turn off Schedule scan to avoid slowing the system performance. )

  1. Double-click Microsoft Security Essentials.
  2. Go to Settings tab.
  3. Click Excluded files & locations. Click Add.
  4. Select the folder where NetCamCenter is installed. Click Save changes.




  5. Click Excluded file types. Click Add.
  6. Enter *.wmv.
  7. Click Add. Enter *.asf.
  8. Click Add. Enter *.jpg. Click Save changes.





22. I want to customize PTZ settings. (see 23.)
23. I setup the camera as an RTSP/MJPEG camera. I can now view the camera. But there's no PTZ (Pan/Tilt/Zoom) control.


  • Please go to your NetCamCenter data folder (default is c:\netcamcenter).


  • Close NetCamCenter

    Download sample Axis ptz file, unzip the file, use it as a template to customize your PTZ commands. You can use notepad to edit the file. Replace Axis camera PTZ commands with your camera's PTZ control. You may need to contact camera manufature or search online for required information.

  • Copy the xml file to NetCamCenter data folder


  • rename it as ipcamptz.x , where x is your camera channel number

    e.g. if your camera on NetCamCenter is channel 3, then rename it as
    ipcamptz.3
    restart NetCamCenter and channel 3 will use the PTZ xml file for ptz commands.
