Temporary File Location

The ExacqVision Client creates temporary files to locally store searched  audio, video, and exported files. Temporary files are created in a directory specified by an environment variable. The following environment  variables are searched in order to determine the path: TEMPDIR, TMP, TEMP,  USERPROFILE.

On systems built after May 2018, these environmental variables usually point to a file location within the C:\ Primary partition on Windows systems. Windows systems built prior to this date would have a 30 GB partition on the first physical disk for the purpose of storing the temporary file directory.

If the allotted space is not sufficient for your searching and exporting requirements, you can move the temporary directory to another location. To do this, complete the following steps:

  1. Run Start, Settings, Control Panel, System.
  2. Select the Advanced tab.
  3. Click the Environment Variables button.
  4. Edit the first of the variables listed above to point to your new location.
  5. Restart ExacqVision Client.

Validating ExacqVision Video (also known as Watermarking or Authentication)

The validation standard used in ExacqVision is known as HMAC, for Hashed Message Authentication Code, and uses a cryptographic hash and secret cryptographic key. HMAC is used by ExacqVision to verify the integrity of exported video.

The ExacqVision Client software calculates and writes out the message authentication code (MAC) during file export. The ExacqVision ePlayer later calculates a hash and verifies the MAC during authentication using SHA-256. The methodology ensures no alteration of the data as the hashed calculations are compared to be certain the hashes match.

To authenticate video in the ExacqVision ePlayer, select Authenticate from the Tools menu.

The following image shows a successful authentication:

Video may only be authenticated using the ExacqVision ePlayer. The ePlayer application is used to playback ExacqVision native files in .PS or .PSX file formats. It is also packaged in self-playing .EXE file exports. For more information on the features of exported file formats, refer to Article 1894.

Changing the Default Export Location

On a Windows-based Exacq NVR, video exported from the exacqVision Client is saved by default to the “exacqVision Files” directory in Documents for the current Windows user. A Windows user logged as a Kiosk user, or logged in to a restricted operating system account cannot select a different directory when saving the exported file, but Windows users with Administrator privileges can select another directory.

On a Windows machine, an administrator may change the default export location within the Windows registry.

WARNING: Only experienced administrators should edit the registry. Incorrect edits can cause drastic changes in the operating system or the OS may fail to work altogether if the wrong keys are changed. Before you edit the registry you should export a copy of the key(s) you plan to change so that this can be restored if problems are encountered.

To change the default export location edit the following key/value pair.

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal

Note: In Linux/Mac systems we write exports to the $HOME/exacqVision Files directory.

Camera Time Stamp Off by Years

Some cameras, particularly AXIS and Sony models, display an OSD date with an incorrect year. The time and date of the camera might be set to GMT and the Windows time is correct on the server, yet the OSD on the screen shows something like March 2, 2001.

<br>

This is usually a result of European Date Formatting (dd/mm/yy). Set the camera to USA date format (mm/dd/yy) to resolve the issue.
