ExacqVision Server crash dumps can be found in the server log folder, typically C:\Program Files\exacqVision\Server\logs. The location of ExacqVision Client crash dump files varies based on the operating system. <br>
There is a known issue when decompressing H.264 video from Arecont cameras that might cause the exacqVision Client or Web Service to crash. This issue appears to be specific to Arecont cameras with hardware version 65212. The H.264 hardware version can be read by browsing to the camera’s web page. Our workaround to this issue is to facilitate the use the avcodec (http://en.wikipedia.org/wiki/Libavcodec) for decompressing H.264 video instead of the Intel Performance Primitives decompressor that is normally used by exacqVision. Arecont tests with avcodec and distributes it with their AV100 software; thus, any incompatibilities with their hardware compression should be minimized.
Following are instructions for downloading and installing avcodec for each supported operating system:
If you are using the exacqVision Web Service, complete these additional steps:
sudo apt-get install libavcodec1d
sudo ln -s libavcodec.so.1d /usr/lib/libavcodec.so
sudo ln -s libavutil.so.1d /usr/lib/libavutil.soIf you are using the exacqVision Web Service, complete these additional steps:
sudo /usr/local/exacq/webservice/service.sh stopsudo /usr/local/exacq/webservice/service.sh startsudo apt-get install libavcodec52sudo mv /usr/local/lib/audacity/* /usr/local/libTo make this fix work with an existing standalone *.exe file, complete the following steps:
Views and Groups are similar in that both of them are logical groups cameras based on more than just the server they are connected to. The major difference is that a View also defines a layout of the cameras onscreen. Because it specifies a layout, the maximum number of cameras in a View is limited to the maximum number of cameras that can be shown onscreen at once, whereas a Group does not have that restriction.

What-is-the-difference-between-a-Group-and-a-View.pdfYes, ExacqVision Client supports multiple monitors. We have tested up to four VGA monitors from a single workstation.
Typically, a user will run one instance of the ExacqVision Client per monitor. Because decompressing video is CPU-intensive, we recommend one core per Client for the best user experience. To drive up to four VGA monitors, we recommend an Nvidia T1000 graphics card. For always-on, higher end multi-monitor displays consider the Nvidia RTX A-2000 up to the Quadro GV100 discrete graphics cards.
The Nvidia P2000 has been tested running the ExacqVision Client with VGA and DVI monitors up to 1920×1200 resolution.

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:
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.
Lower Frame Rates Displayed Than Expected

If the red X appears over the cursor, the window is too close to the edge of the image.
Additionally, if you cannot digitally pan or tilt after zooming, the pan/tilt speed might be too high. The speed setting is the number of pixels to move in the image.
Click the PTZ Control button on the toolbar.
Decrease the Speed setting for the Pan/Tilt control.

In most cases, yes. Exacq strives to make the client software backward compatible. However, we recommend that you upgrade your client because newer versions have additional features, bug fixes, and enhancements. Older versions usually function correctly, but they most likely do not offer all the current exacqVision client features.
<br>
Is-my-exacqVision-Client-software-backward-compatible.pdfModern computer networks require each device on the network to have a unique IP address. These addresses are used so that computers know how to communicate with each other and so that network equipment knows where to route the traffic crossing its path.
When using the ExacqVision Desktop Client application from a client workstation to connect to your ExacqVision Server application on another machine, perhaps on the other side of your office, you will need to enter the server’s IP address so the two machines can communicate.
However, TCP/IP includes some “shortcuts” that make routing communication more efficient when two applications running on the same machine need to communicate. These “shortcuts” are called loopback addresses and tell the machine not to bother sending the message out onto the network only to have the network send it right back.
127.0.0.1 is an IP address that always refers to “this machine”; the local computer. An ExacqVision Client can always connect to a server running on the same computer using the 127.0.0.1 IP address, regardless of the actual IP address being used by the NIC in the computer. The same can be said for “localhost,” which may be used in place of the address 127.0.0.1 in many applications. Both “localhost” and the address 127.0.0.1 refer to “this machine.”
Do not delete 127.0.0.1 or ‘localhost’ from your systems list. Using 127.0.0.1 instead of the actual IP address of the NIC ensures the fastest and least troublesome connection to the ExacqVision Server running on the same computer.
<br>
The 127.0.0.1 loopback address is an IPv4 address. While IPv6 has been a growing protocol for several years, it is still primarily used by service providers and external routing. Within private networks such as offices and homes, the older IPv4 protocol is still standard.
In case you’re wondering, the loopback address in IPv6 can be written as:
0:0:0:0:0:0:0:1 or as ::1
At the time of this writing, ExacqVision Server does not support IPv6 addressing.

All versions of exacqVision software are released at the same time because the code that runs on Windows is the same as the code that runs on the Linux and macOS platforms but compiled for each operating system.
exacqVision Server, Web Service, and Enterprise Manager are currently available for Windows and Linux.
The exacqVision Desktop Client is available for Windows, macOS, and Linux.
