Migrating from HDVR to ExacqVision (Legacy)

Features gained by upgrading from HDVR to exacqVision:

  • 2-way audio added for certain cameras (see camera database to determine which cameras support this feature).
  • Remote server update is now accessible.
  • Archiving features available on Windows 7 systems (not supported in Windows XP).

The Exacq 6.0 Bundle installer consists of three components:

  • Server
  • Client
  • Web Service

This HDVR replacement bundle installer requires user intervention to complete the process. This document includes procedures for each component’s installer. After the HDVR installers are replaced with the exacqVision installers, use exacqVision versions for all future installations.


NOTE: After the migration, you will see the exacqvision “V” logo instead of the HDVR logo in all icons and shortcuts.

exacqVision Server

If the installer detects a previous HDVR server installation, a licensing message appears.

Click OK to install exacqVision Server over the existing HDVR server installation. This will install to C:\Program Files\HDVR, and video will be saved to existing directories.


exacqVision Client

If the installer detects a previous HDVR client installation, a warning message appears:

Click OK to install exacqVision Client over the existing HDVR client installation. This will install to C:\Program Files\HDVR, and all configuration XML files will be saved and applied to exacqVision Client.


exacqVision Web Service

If the installer detects a previous HDVR web service installation, a warning message appears:

Click ‘Yes’ to uninstall LightTPD and install Apache for better performance. You will lose configuration settings. See https://exacq.com/support/specsheets.php?perma=exacqVision+User+Manuals for configuration instructions.

Hiding a Web Server from Internet Searches (Legacy)

NOTE: This document only applies to exacqVision Web Service 2.4.0 to 8.8. Web Service 9.0.0 replaced Apache with proprietary WFE service.

If your exacqVision Web Service is connected to the Internet, the server could be located using certain search parameters in a search engine. To hide the server from an Internet search engine, complete the following procedure:

<br>

Note: Depending on the operating system, you might need to log in as an administrator to complete this process.

  1. Browse to C:\Program Files\exacqVision\WebService\Apache2.2\htdocs.
  2. Use Notepad to create a text file named robots.txt.
  3. Add the following lines to disallow all indexing on the entire Web Service:
  4. Restart the Web Service to ensure all changes are published.

Stack Overflow in S2 Integration in Internet Explorer 8

If you are using Internet Explorer 8 to connect to an S2 access control system integrated with exacqVision, a “Stack overflow error 0” message might appear repeatedly. This issue occurs more often if the S2 and exacqVision systems are connected on the same LAN, and it is caused by the way Internet Explorer 8 handles exacqVision JavaScript.

To avoid the error message, upgrade to S2 Release 4.1, Build 453 firmware, which is available from S2. Alternatively, you could connect to S2 using the Mozilla Firefox browser.

Changing Web Server Default Image Quality (Legacy)

Instructions

These instructions only apply to web services 9.4 and earlier. 

The changes described only affect the default image quality in “simple” mode and this process is not upgrade safe. You must perform this process again each time you upgrade Web Server.

<br>

  1. For Windows: Browse to C:\Program Files\exacqVision\WebService\bin\templates.

    For Linux:     Browse to /usr/local/exacq/webservice/bin/templates.
  2. Open the file config.html.mako.
  3. Look for the following section:

    query_string = urllib.urlencode([(“s”, hex(server.id)),
                                       (“p”, camera.plugin),
                                       (“d”, camera.device),
                                       (“i”, camera.input),
                                       (“w”, “320”),
                                       (“h”, “240”),
                                       (“q”, “7”)])
  4. Add a line to the end of that section as follows:

    query_string = urllib.urlencode([(“s”, hex(server.id)),
                                       (“p”, camera.plugin),
                                       (“d”, camera.device),
                                       (“i”, camera.input),
                                       (“w”, “320”),
                                       (“h”, “240”),
                                       (“q”, “7”),
                                       (“r”, “5”)])
  5. Change the values to match your preferred settings for the following parameters:

    NOTE: Starting in Web Server 2.1, the following values are stored in a cookie generated from the Web Server. However, you can add these values to the config.html.mako file to override the cookie.

    w = width
    h = height
    q = quality
    r = refresh interval
  6. Save the file.
  7. Open or refresh the Web Server page in your web browser.

When I use a web browser to view the video from the exacqVision Web Server, do I need to install any additional software or applets?

No. The exacqVision Web Server transcodes video into a JPEG that can be viewed by any modern web browser. This allows anybody to use the Web Server without downloading or installing additional software.

Can the Web Server run on an Exacq EL NVR system?

Yes, exacqVision EL supports a Web Server used to provide the mobile device video access. The Web Server is not installed on EL by default because if it runs simultaneously with exacqVision Client on the EL hardware, performance of both the local client and the Web Server could be noticeably slower (this is the tradeoff for the low power consumption and reduced cost of the Intel Atom processor). The loading introduced by the Web Server is roughly equal to the client. Remote clients connected to the exacqVision Server do not introduce significant CPU loading.

<br>

On exacqVision ELP systems, the Intel Celeron processor can run exacqVision Client and Web Server simultaneously. exacqVision Client performance is still dependent on the processor. See Client Workstation Hardware Requirements on this page for more information.

<br>

The installation of the Web Service is very easy and no different than for any other Ubuntu Linux-based system. The Web Service installer is available at https://exacq.com/support/downloads.php.
