Redundant Recording - Store Your Surveillance System's Recordings in a Second Location Automatically

You've heard the horror stories. Someone breaks in and steals the surveillance system. Don't worry. Our NVRs can automatically backup your footage.

There are Five Ways that our NVRs can Create Redundant Recordings

1. NAS

NAS NVR backup

A NAS or Network Attached Storage is an easy way to either increase the storage space available to your recorder or have a redundant, off recorder storage device - allowing you to have two copies of recorded footage.

You set both the internal and NAS hard drives into groups and assign the cameras to groups. This way you can set some cameras to record longer than others.

NAS backup is available on all of our Admiral or Imperial NVRs (the Admiral and Imperial lines launched in 2018). NAS was also availible on our 8, and 16 channel Vanguard NVRs, and our 32, 64, 80 and 128 Channel Executive NVRs.


2. Snapshot

Snapshot FTP upload

Snapshot is only available on our Admiral and Imperial lines (both which launched in 2018). Snapshot is less of a "continuous backup" and more of an "emergency backup" because Snapshot creates images of the last thing the camera saw before a certain event occured and then automatic upload those images to a FTP Server location. Snapshot prioritizes sending data as quick as possible, so it doesn't upload video files, but rather images - snapshots of what is happening in the moment. Although it can be used for many other things, it is most useful in scenarios where the NVR might be stolen or damaged, as it is designed to upload photos as quickly as possible offsite.

Snapshot options are based upon your current recording mode. When a VCA event happens, the NVR can capture a series of snapshots and upload those images to a FTP server of your choosing. When motion is detected, the NVR can capture a series of snapshots and upload those. When in Continuous mode, the NVR can upload an image at a certain interval, such as every hour. If you have a NVR or cameras with alarm inputs and you have connected an alarm device to those inputs, the NVR can capture a series of snapshots and upload those images to a FTP server of your choosing when an alarm goes off. There's no monthly fee for this, as it uses your FTP server.

3. eSata

Our Imperial, Executive, and Edge lines of NVRs have an eSata connection on the back so that you can attach a hot swappable eSata drive array which can function as either a backup or extension of your internal drives.

You set both the internal and eSata hard drives into groups and assign the cameras to groups. This way you can set some cameras to record longer than others.


4. RAID

RAID (redundant array of independent disks) is allows your NVR to combines multiple, internal, disk drives into a singular unit for the purposes of data redundancy or performance improvements.

Our entire Imperial Line (launched in 2018) can do RAID 0, 1, 5, 6, 10 and the Imperial 128 Channel can also do RAID 50 and 60.

Our Executive and Edge line NVRs can do a RAID (0,1,5,10) hard drive partitioning which create redundancies of recorded video for clients who face regulatory, investigative, or other challenges that would make retaining backup copies of the NVR's footage mission critical. Enabling RAID requires around 100 Mbps in bitrate on these Executie and Edge units because they have software RAID rather than hardware based RAID.


5. Hot Swap

Our Imperial 128 NVR (launched in 2018) has Hot Swap, which means that it has the ability to remove a hard drive while it is running and install another one.

This is useful if you need to archive footage long-term, to create backups on external media, or to replace a failed drive without turning off your recording. Normal hard drive setups require you to power off the device, take off the case, and connect cables.


6. Hot Spare

The Imperial line of NVRs, our enterprise level of NVRs offers the ability to set a redundant, backup NVR on the network. The redundant NVR will automatically take over cameras in seconds after detecting issues with the main NVR, giving you virtually zero downtime. When the main Imperial NVR is restored, the redundant NVR will transfer footage back to the main imperial seamlessly.

Key Features:

  • 24/7 Redundant Operation
  • Virtually zero downtime
  • Restores footage to main NVR when restored
  • One redundant NVR can backup multiple NVRs

Diagram for one NVR

If you have a single Imperial NVR and you wanted to have a redundant Imperial you simply have to connect the redundant Imperial to your main network using LAN1 and connect the camera network/switch to LAN2.

This will give the redundant Imperial access to both capture cameras and communicate with the Imperial on your main network for any status issues.

Multiple NVR Setup

Multiple Imperial Diagram

For networks with multiple Imperial NVRs - you can have just one Imperial act as a redundant unit, lowering your costs by preventing the need to have one redundant for every NVR.

To setup a multiple redundant setup you will have to connect both camera networks to the redundant and connect the NVR to the your main LAN.

In order to connect multiple camera networks to your redundant Imperial you will need a switch. Ensure that the switch is gigabit speed and will not bottleneck camera traffic.

Note: The redundancy for multiple NVRs depends on channel number. For example, a 64 channel Imperial could pick up and back up two 32 channel Imperials or two 64 channels could be backed up to a 128 channel.
