What is the VGA Acceleration Mode feature on the Client page?

The process of decompressing and displaying hundreds of video images per second is processor-intensive. It is possible to use the capabilities of modern display adapters to offload the main workstation processor from some of this work.<br>

The ExacqVision Desktop Client tries to automatically determine the best operational mode and colorspace for the available display hardware. Because various display adapter vendors have different levels of support or tests for the various modes and colorspaces, occasionally situations arise where the automatically detected mode does not work properly. The Client settings page allows the user to control the selection of the mode and colorspace of the display acceleration.<br>

The following modes are available:

  • In Auto mode, the Client will attempt to detect the correct GPU decoded path for your operating system. The Client will revert to None automatically if it detects that the display adapter does not support that mode.
  • In Direct3D mode, additional options are available for selecting specific colorspaces. Direct3D is a decoding method developed by Microsoft for Windows only GPU decoding. Direct3D enables applications to interact with display hardware from any vendor that provides a Direct3D driver and provides a method for applications to determine the modes of hardware acceleration that are available in the display hardware.
  • In OpenGL mode, additional options are available for selecting specific colorspaces. OpenGL is a cross-platform GPU decoding method, meaning it can be used on non-Windows operating systems as well. When selecting OpenGL, the processor decompresses the frame and provides it to the display adapter in a supported colorspace. The display hardware scales the image and copies it to the overlay buffer. Each time the monitor retraces, the display adapter combines the frame buffer with the overlay buffer to produce an output. This mode offers the best performance because the workstation processor does not have to scale images or convert colorspace. It also reduces flicker because any onscreen graphics are in the frame buffer, which is independent of the images that are updated in the overlay buffer.
  • In None mode, the workstation processor does all the work and makes no use of display adapter acceleration. The None setting for VGA acceleration is the most conservative setting in terms of minimizing potential issues with VGA drivers. However, selecting None requires more CPU horsepower to decompress and display images in the Client.

NOTE: While the None mode is reliable, because it does not depend on a driver from the display adapter manufacturer, this mode could result in a reduced displayable frame rate if the workstation processor is 100% in use. You can assess this setting in a Windows Client by running Task Manager and monitoring CPU usage while running in Live Mode. Remember that a single instance of the Client cannot run on multiple cores, so if you have a two-core processor, it might display 50% CPU usage when fully loaded by a single Client.

The following article may also help in determining the cause of any frame rate discrepancies.

How can I find the version of my exacqVision Client, Server, or Web Service software?

exacqVision Server

  1. Open the exacqVision Client and connect to the server. Click the Configuration (gear icon) button.
  2. Select Systems from the Configuration tree to open the Systems page.
  3. Find the entry row for the server.
  4. View the version number in the Version column. (If you do not see the Version column even if you scroll all the way to the right, right-click a column header and make sure ‘Version’ is selected.)

Does the exacqVision Server support automatic burning of video files to CD/DVD or USB?

Yes, exacqVision’s Auto Export profiles allow you to automatically burn a specified video event to a writable CD, DVD, or USB thumb drive. This function can easily be associated with a soft trigger button in the exacqVision Desktop Client using Event Linking.

CD/DVD writing is a one-time operation for each export. If using a USB thumb drive, Auto Export may be performed multiple times up to the drive capacity.

Auto Export is performed on the server, so the media you choose must be inserted into the NVR, not your Client workstation.

View our User Training Videos on Auto Export and Event Linking, or refer to the exacqVision User Manual for more information

What IP cameras are supported by ExacqVision?

IP Camera Integration Database

ExacqVision supports thousands of cameras from a large number of manufacturers. The IP Camera Integrations database provides a complete list of test records for supported camera models. Search by brand, model, or firmware version, and filter by camera feature.

The following video describes how to use the database to its full extent:

<br>

What if my camera isn’t listed as supported?

It would be impossible to list every camera ever made. However, just because a camera model isn’t listed doesn’t necessarily mean it will not work with ExacqVision. It DOES, however, mean that we cannot assure any features or functionality.

  1. If you find that a particular firmware version from your camera manufacturer is listed as supported on another model from the same brand, there is a good chance it will work with the same Plugin/Device Type listed.<br><br>
  2. If your camera supports Onvif, it may still work if you add it to your system selecting ‘Onvif’ from the Device Type selector. Note, that while Onvif is described as an open standard, not all manufacturers implement it adhering to the standards. Additionally, some advanced functionality may not be supported when using Onvif.

    Onvif compliant cameras are not usually considered “plug and play,” meaning that minor software revisions may be necessary to receive metadata regarding motion data or other signals.<br><br>
  3. If your camera provides an RTSP video stream, a final option may be to use the ‘RTSP’ Device Type. This would allow ExacqVision to record the video stream only. Features such as motion data, analytics, and inputs/outputs are not supported via RTSP.

Will Exacq support my camera?

While Exacq supports a very large number of cameras, that cover a wide range of capabilities and features, we also understand that your particular camera or firmware may not be listed as supported.

What can you do? See the below section.

Submit a request for testing

  1. From the IP Camera Integrations database, click Can’t Find Camera?
  2. Complete the New IP Camera Integration Suggestion form.
  3. Check ‘I’m not a robot,’ to pass the Captcha test.
  4. Click Submit Form.

This form will provide your request to our Product Team for consideration. Please be aware that we plan our releases months in advance, and we can not guarantee that support for your camera will be available in a specific time frame. If you have a sizeable project that requires a camera we do not support please contact Sales to discuss your requirements.

Assigning the Device Number to an eDVR Board in Linux

To assign the device number to an eDVR board in Linux, complete the following steps.
<br>

NOTE: This process is usually required when replacing or adding boards. This is the same as using Control Center in Windows.

  1. Exit the ExacqVision software.
  2. Open the Terminal from Start>Accessories>Terminal.
  3. Type the following to stop the Exacq Service: sudo /etc/init.d/edvrserver stop
  4. Type the following: sudo /usr/local/xdvapi/bin/startxdvmods
  5. Type the following to detect an initialize the boards in the system: sudo /usr/local/xdvapi/bin/startxdvccl. This will remove the old entries for the board and check for any existing boards.
  6. Type the following to stop the XDV: sudo /usr/local/xdvapi/bin/stopxdvmods
  7. Type the following to start the Exacq Service: sudo /etc/init.d/edvrserver start

<br>
You should now be able to launch the exacqVision software and see your boards.
