When using the audio input terminals on the rear of an ExacqVision Hybrid NVR, you will need a microphone with a a pre-amplifier capable of producing a line level output that can be connected directly to the ExacqVision audio terminal inputs.
If using a mic level output microphone, you will need a mic pre-amp to boost the audio to line level output for connection to the rear audio input terminals.
There are many options available in the market. The following is a list of some common choices:
- Louroe ASK-4 #101 Single-Zone Kit
- Louroe ASK-4 #102 Single-Zone Kit
- Louroe ASK-4 #104 Four-Zone Kit
- Louroe ASK-4 #108 Eight-Zone Kit
- AKG PZM10 LL Microphone with line level output
- AKG PZM11 LL Microphone with line level output
- ETS SMI-9 Eight-Zone Kit
If you choose to use other surveillance or boundary layer microphones with mic level or XLR connection outputs you will need an intermediary device that provides a line level output to use with the audio input terminals.

ExacqVision Server software has supported 64-bit Windows since Server version 6.4.
sDVR and tDVR analog capture board installers for 64-bit Windows ExacqVision Hybrid systems are also available.
For a list of currently supported operating systems, refer to the software product pages on Exacq.com, then click ‘System Requirements.’

Yes. Exacq offers the exacqVision Surveillance Keyboard for this purpose.

If you have replaced a failed/failing hard drive, or added an additional hard drive to your Windows system in a JBOD (non-RAID) configuration, the steps below will guide you through setting up the drive for recording using Windows OS tools.
NOTE: It is best practice to make hardware changes with the system powered off.<br><br>
- Log into the operating system of the system running the ExacqVision Server application with administrator privileges.<br><br>
- Open the Disk Management tool.
- Windows 11, 10, 8, 7
Click on the Windows (Start) icon and begin typing ‘Create and format’ or ‘Disk management’ to locate the ‘Create and format hard disk partitions’ option from the Control Panel. Click to open it.
<br><br>
- Windows 11, 10, 8, 7
- The newly added disk will not be listed by Windows until it has been configured. Windows will typically detect this and automatically prompt you to initialize the new disk. If it does not, simply open the ‘Action’ menu and select ‘Rescan Disks’.
<br><br> - In the pictured example, this is the second SATA spinning hard disk added so it is listed as ‘Disk 2’ under ‘Select disks’.
Modern disk sizes, greater than 2 TB, require you to select ‘GPT (GUID Partition Table)’ as the partition style. Select ‘OK’ to continue.
<br><br> - The disk now appears as ‘Unallocated’ space.
<br><br> - Right-click the ‘Unallocated’ space and select ‘New Simple Volume…’ to begin the New Simple Volume Wizard.
<br><br> - In the New Simple Volume Wizard, click ‘Next’.<br><br>
- You will be asked to specify the volume size. By default this should automatically be set to the size of the entire disk, creating one large partition for the entire disk. This is fine for ExacqVision use and will create one “Drive Letter” for each partition seen by Windows. Click ‘Next’.
<br><br> - The example system, pictured, already has a C: volume for the operating system, as well as a D: volume for the first recording disk. You may select any unused drive letter for your new volume, but it is common to select the next sequential letter, in this case E:, so click ‘Next’.
<br><br> - Use the default chosen, ‘NTFS’ as the File System for the new volume and the ‘Default’ Allocation unit size. You may leave the Volume label as ‘New Volume’ if you choose. Click ‘Next’.
<br><br> - Click ‘Finish’ to accept your selections and close the wizard.<br><br>
- The system will quickly format the new volume and you will see this listed in the Disk Management screen.
<br><br> - Before ExacqVision can see this new volume and use it for recording you must restart the ExacqVision Server service.<br><br>
- Click on the Windows (Start) icon and begin typing ‘Services’, and click to open Service from the Control Panel.
<br><br> - Locate ExacqVision Server, click to highlight it, and choose one of the following:
- Click the ‘Restart’ icon from the toolbar.
- Click the ‘Restart’ link from the left-hand options.
- Right-click the highlighted ExacqVision Server row and select ‘Restart’.

If you are looking to add a surge protector between an analog PTZ camera and your ExacqVision server, some options that provide both BNC video connections as well as RS-485 terminals such as the following:
If a system is built with the Radisys motherboard or has two or more eDVR boards, there are more then four serial ports. However, Ubuntu 8.04 enumerates only four serial ports by default. To change the number of serial ports enumerated, complete the following steps:
<br>
- Edit menu.lst by typing sudo nano /boot/grub/menu.lst
- Find the line that starts with # kopt= and ends with ro and add the following to the end: 8250.nr_uarts=16
- Save the file by pressing Ctrl-o and then Enter.
- Exit by pressing Ctrl-x.
- Execute the following command to refresh grub: sudo update-grub
<br>
NOTE: The first character in “lst” is the lowercase letter L and not the number 1.

Enumerating-more-than-Four-Serial-Ports-in-Linux.pdfTo disable automatic login on Linux, complete the following steps:
- Log in to the Admin account.
- Run Start -> System -> Administration -> Login Window.
- After you enter the admin password, the Login Window Preferences dialog appears. On the Security tab, deselect Enable Automatic Login. You can also change the User to admin if you want to always login as admin; however, this is not recommended for security reasons.

Disabling-Automatic-Login-in-Linux.pdfRun fsck
On Linux systems, if a disk encounters a filesystem error, the physical drive may still be good but require a file system consistency check. Perform the following steps to attempt to correct this.
If the affected volume is a video storage volume:
- Stop the ExacqVision server service. Open a Terminal window and enter:
sudo service edvrserver stop<br><br> - Unmount the volume:
sudo umount /mnt/edvr/X
Replace the ‘X’ with your volume number.
Example: If you have a write error on /mnt/edvr/2, you would enter:
sudo umount /mnt/edvr/2
NOTE: If this command fails, see Appendix below.<br><br> - Run fsck on this volume, again replacing ‘X’ with the volume number:
sudo fsck -yv /mnt/edvr/X
This command will tell the system to automatically attempt to fix any issues it encounters. This may take minutes or several hours depending on the number of filesystem errors and the size of the volume. When completed, the Terminal will return to a prompt awaiting a new command. <br><br> - When you have run fsck on all the affected storage volumes, reboot the system by entering:
reboot
OR
Return to the Desktop and use the power icon to restart the machine. The drives will remount upon boot up.<br>br>
<br>
Appendix
If drive fails to unmount, you will need to open the fstab file and comment out the mount point of the drive in question.sudo gedit /etc/fstab
- You will need to place a ‘#‘ character to the left of ‘Label=/mnt/edvr/X’
- Save
- Reboot the machine.
- The drive that was commented out should not be mounted at this point.
Continue with step 3 above.
Reminder: Do not forget to re-edit the fstab after the fsck is finished and remove the # you added.

What does fsck do?
The fsck command performs a consistency check and attempts to repair the filesystem from errors.
What causes filesystem errors?
When system processes or user activity require saving data or making changes to the filesystem, that data is first written to a buffer in memory (RAM). The system periodically moves the data waiting in the buffer to the hard disk. Therefore, at any moment, there is a difference between file changes waiting to be written to disk and what exists on the disks.
Filesystem errors and inconsistencies can develop due to hardware degradation, system halts, or unclean shutdowns. Sudden power loss and forced shutdowns occurring before the changes in the buffer are moved to permanent disk storage.
Components checked by fsck
Inodes
Inodes contain metadata about a file, which includes information like: whether the file is read/write or read-only, the type of file, the user ID of the file owner, file creation and modification date and time, and the number of bytes in the file.
Data Blocks
These contain the data that actually makes up the file.
Superblocks
The superblock contains details about the filesystem, such as the state of the filesystem, the filesystem size, the filesystem name and volume name(s), path name of the mount point, and number of inodes. Every change to the inodes also requires changes to the superblock.
