3 GETTING STARTED

This chapter describes the initial steps required to start using the NVR-AS 4000.

Server installationFollow the instructions provided in the Getting Started Guide to safely install the server.

Before installing the NVR-AS 4000, review the safety instructions and guides provided withthe system.

Complete the operating system setupWhen you power up the NVR-AS 4000 for the first time, Windows performs initialconfiguration. During the initial configuration:

• Specify the locale• Read and accept theWindows license agreement• Define the administrator password.

The passwordmust meet the following criteria.• Be at least six characters in length• Contain characters from three of the following four categories:

English uppercase characters (A through Z)English lowercase characters (a through z)Base 10 digits (0 through 9)Non-alphabetic characters (for example, !, $, #, %)

During this process, Windows may reboot a number of times.

AfterWindows configuration is complete, the NVR-AS 4000 InstallationWizard opens. Usethe wizard to:

• Read and accept the IndigoVision license agreement• Specify aName and Location for the device• Choose whether to start an ONVIF recording trial or use a standard server license

On completing the wizard, it performs device configuration and prepares the video storage. Ifyou don't complete the wizard, you are prompted to do so again the next timeWindows startsup.

10 User Guide - v7

Do not interrupt device configuration and storage preparation after it has started.

When the configuration process has finished, Windows reboots. After the reboot, the NVR-AS 4000 is fully operational.

On delivery, the NVR-AS 4000 RAID arrays commence a background initialization process.During this operation the RAID array is fully operational but does not have full redundancyuntil it completes. The process takes up to 25 hours.

You can now configure the network settings as normal. DHCP is enabled by default.

All devices in the IndigoVision system should be time synchronized using the same NTPserver. If they are not, warnings are issued, and certain functionality may not behavecorrectly, including aspects of video playback.

ONVIF recording trialThe standard NVR-AS 4000 license permits recording any number of IndigoVision proprietaryprotocol streams indefinitely (up to the stream limit of the device). It also permits recording asingle ONVIF stream.

If you want to start recording from multiple ONVIF streams straight away, an optional triallicensemechanism is provided.

You must register a full license before the trial expires to continue recording more than oneONVIF stream.

An ONVIF recording trial runs for seven days from the point that the installation wizardconfigures the NVR-AS 4000. During the seven day period the trial permits recording anynumber of ONVIF streams (up to the stream limit of the device) from the following:

• IndigoVision BX Range• IndigoVision Ultra Range• Third-party ONVIF cameras• Third-party cameras integrated through Camera Gateway.

After you start or reject the trial and have selected Next in the installation wizard, the chosenlicense is programmed and the option to start a trial is no longer available.If you chose to reject the ONVIF recording trial license, the installation wizard sets up astandard NVR-AS 4000 license.After you have rejected the trial license option, you cannot select this option at a later date.

4 OPERATIONS

This chapter describes common tasks required for the operation of the NVR-AS 4000.

Disk managementDisk and array management uses the Dell™ OpenManage™ Server Administrator (OMSA).TheOMSA can be started from the desktop shortcut or from the Start menu. These shortcutsopen Internet Explorer with the correct URL to allow maintenance of the server.

• When accessing the OMSA, Internet Explorer indicates that there is a problem withthe website’s security certificate. Click Continue to this website to open theOMSA.

• Internet Explorer then opens aWindows Security dialog requesting credentials. ClickCancel to close the dialog.

• TheOMSA then requests credentials. Enter the user name Administrator and theadministrator password currently set for the operating system.

Alternatively, you can configure Internet Explorer to avoid the requests for credentials:

1. Select Tools > Internet Options in Internet Explorer. The Internet Options dialogopens.

2. Click Local internet from theSecurity tab.3. Click Sites.4. Clear the check box Automatically detect intranet network.5. Select the check box Include all local (internet) sites not listed in other zones.6. Click OK. The Local internet dialog closes.7. Click OK. The Internet Options dialog closes.

The next time you start OMSA from the desktop shortcut or the Start menu, click Continueto access OMSA, without having to enter the credential checks.

RAID redundancyThe 2U variant uses RAID1 for operating system and configuration information, and RAID6for video storage. The 1U variant uses RAID5 for both video storage, and operating systemand configuration information.

The RAID1 and RAID5 array can tolerate a single disk failure. The RAID6 array can tolerateup to two disks failing.

If a disk fails, it must receive attention at the earliest opportunity to maintain maximum arrayredundancy.

14 User Guide - v7

Replacing a faulty diskWhen the Dell OpenManage Server Administrator (OMSA) reports that a disk is faulty, itmust be replaced as soon as possible. Contact IndigoVision Partner Support to arrange for areplacement to be supplied.

• Remove the faulty disk and replace it with a disk of the same capacity.• The RAID controller automatically incorporates the replacement disk and starts

rebuilding the array.• Confirm that the disk is incorporated into the array and has started rebuilding using the

OMSA.• In some cases the disk may need to bemanually added as a hot spare. Shortly after

adding a new disk, the controller starts rebuilding the new disk.

In the rare event that two disks have failed in the NVR-AS 4000 2U variant:

• Replace one disk and allow it to completely rebuild.• After the first disk has completely rebuilt and the array has redundancy, replace the

second disk.

Do not remove disks unnecessarily while the device is in operation. This causes the systemto consider the disk as failed.

Whole storage array replacementWhole storage array replacement is only possible on the 2U variant. This allows a runningstorage array to be archived.

Archiving a running storage array

You can archive the storage array from a 2U variant by removing the disk array.

1. Navigate to theServices Panel on the NVR-AS 4000.2. Stop the IndigoVision NVR-AS service.3. Disable the IndigoVision NVR-AS service.4. Shut down the device so that it powers off.5. Remove the entire storage disk array.

Label the disks appropriately to ensure you can identify them at a later date.

After you have removed the disk array, you can replace them with either:

• An archived disk array, or• A new set of disks that can be configured as a blank storage array.

Restoring an archived storage array

You can restore an archive storage array to a 2U variant by replacing the archived disk arrayin an NVR-AS 4000 that contains no storage disks.

The NVR-AS 4000 is configured using the NVR-AS Administrator. You can access this toolvia the Start menu:

Start > IndigoVision > NVR-AS > NVR-AS Admin

It is not possible to use the NVR-AS Administrator until you have completed the initialinstallation of your NVR-AS 4000.

Identification dialogEnter the server (NVR-AS) name and location as required. These are the name and locationthat are used by IndigoVision Control Center and other client applications.

Storage dialogUse this dialog to specify the locations where data is stored.

• Video: Specify the path to the Video Library (where recordings are stored)• Configuration: Specify the path to the folder containing configuration information

Click to browse to the required locations.• Advanced Configuration: Select Override Database Paths if you wish to store the

Alarm and/or Bookmark databases in a location other than the default. This canimprove performance when configuring an NVR-AS to review archived footage,alarms, and bookmarks.

Network Settings dialogUse this dialog to configure the NVR-AS network settings.

22 User Guide - v7

• Recording Stream Limit: This setting specifies a limit for the number of recordingstreams (1-200) on the NVR-AS. Use this setting to avoid exceeding the NVR-ASrecording capability (typically limited by storage bandwidth).

• Playback Bandwidth Management: Select Enable to manage the playbackbandwidth.• Bandwidth Management Address: This is the IP address of themachine hosting

the bandwidthmanager.• Bandwidth Limit: This is themaximum bandwidth available to a playback

session. The bandwidth is shared between all playback streams in a session.• NVR-AS IP Address: This is the IP address on the local machine that the NVR-AS

uses to communicate with Control Center and IndigoVision transmitters. This option isonly available on systems that havemultiple IP addresses. Defining the IP address isuseful when the NVR-AS uses IP based storage, such as an iSCSI SAN.

Disk Space Management dialogUse this dialog to configure the disk spacemanagement settings.

• Maximum Chunk Size: This is the largest size that a recording chunk can be before anew chunk is automatically begun. If you are recording at a high bit rate, youmay wantto set this at a higher value to limit the number of recordings that the NVR-AS andControl Center have tomanage.Smaller chunk sizes are useful when using the Protect On Alarm feature tominimizethe amount of disk space used. Care should be taken when selecting the chunk size tolimit the total number of recordings to be under 100,000 otherwise system performancemay be compromised.

Themaximum length of a chunk is four hours of footage.

• Video VolumeMinimum Free Disk: This displays theminimum amount of space thatshould be left free on the NVR-AS. The value is calculated from themaximum numberof streams the NVR-AS can record and themaximum chunk size.

If the value is > 5% of the total disk volume the system displays a warning. If the amount offree disk space does not leave enough space for recordings, reduce theRecording StreamLimit or theMaximum Chunk Size.

• Reaping• Space: Recordings are only deleted when the NVR-AS disk is becoming full.• Time and Space: Recordings are deleted either when the NVR-AS disk is

becoming full, or when recordings reach a specified age (max age).

Do not select the Time and Space option on an NVR-AS which you use to play back archivedrecordings.

• Maximum Chunk Age: This specifies the length of time that recordings are stored onthe NVR-AS before they are automatically deleted.

User Guide - v7 23

Recordings which aremarked as protected are never automatically deleted.

• Enable tamper protection on recordings: The NVR-AS will embed digitalsignatures in every recording file allowing the authenticity and integrity of that footageto be verified at any point in the future.Verification will happen whenever footage is exported by Control Center as part of anIncident and the result of the verification will be written into the Incident. This providesan extra level of security: the Incident itself is protected by a watermark proving thatthe Incident has not been tampered with, and the NVR digital signatures prove that thefootage on the NVR had not been tampered with at the point of export.Tamper protection is not compatible with Video Thinning, so Video Thinning isautomatically disabled when tamper protection is enabled.

• Enable video thinning: Video Thinning removes the intermediate P-frames leavingonly independent I-frames. This leads to a dramatic reduction in the storagerequirements but at the expense of full motion video.For effective use of video thinning, it is important to configure themaximum I-frameinterval on the transmitter such that the frame rate of thinned footage is acceptable.Video Thinning is most effective on footage with significant amounts of motion.MJPEG and JPEG 2000 streams only contain I-frames, so thinning does not have anyeffect on footage in these formats.

• Reduce storage to I-frames only after: Video thinning is performed on footage oncethe time entered here has elapsed.

• Enable automatic unprotect of video: Select this checkbox to automaticallyunprotect video older than the age specified inUnprotect video after.

Enabling Automatic Unprotect in conjunction with Reaping can result in the loss of videodata that has been protected for the purpose of providing evidence relating to an incident.

• Unprotect video after: Video will be unprotected only when it becomes older than theage specified here.

Alarm and Data Record Management dialogUse this dialog to configure the alarm and data recordmanagement settings.

• Zone Alarm Reaping: This automatically deletes zone alarms based on their age.Select the check box and enter the time after which zone alarms will be deleted.

When zone alarms are reaped, any activations that contributed to those alarms are alsoreaped.

• Activation Reaping: This automatically deletes activations that are not part of analarm based on their age.Select the check box and enter the time after which activations with no associatedalarm will be deleted.

• Data Record Reaping: This automatically deletes data records based on their age.Select the check box and enter the time after which data records will be deleted.
