Zero-loss Failover for Servers and Cameras with Surveillance HA

Safeguard your mission-critical data with Fault Tolerance for Milestone XProtect workflows. Ensure business continuity with 100% failure response success, live camera continuity, and immediate access to previous recordings. Unmatched flexibility that answers the needs of organizations with a high intolerance to camera data loss.


What Can You Achieve with Surveillance HA?

Fault Tolerance

The Surveillance HA configuration ensures that if the primary server fails, the secondary server takes over immediately with no disruption to operations and not a single video frame lost.

Uninterrupted Access

Maintain immediate access to previous recordings in the event of server failure. It is so transparent and seamless your operators may not even notice a failover took place.

Easy & Transparent Management

Easily set up and manage High Availability clusters without third-party tools. This comes complete with a dashboard providing a snapshot of recording server stats.


How Does Surveillance HA Work?

Surveillance HA is a software-only failover solution that supports two configurations for maximum flexibility: Server Cloning and Camera Pairing.

In the Server Cloning failover configuration, the Primary and Secondary servers share the same configuration and form a cluster. To a Management Server, both servers appear as a single machine. In this configuration, both recording servers share the same cameras, frame rates, and resolutions. Only retention periods can vary.

In the Camera Pairing failover configuration, the Primary and Secondary servers maintain completely independent configurations, and can even report to different, federated Management Servers. Surveillance HA connects Smart Clients to the selected camera feed seamlessly via one of two available Recording Servers. This configuration enables support for different cameras, frame rates, resolutions, and retention periods on each recording server.

Surveillance HA at a Glance


Two Configurations for Maximum Flexibility

Protect mission-critical deployments with zero-loss failover. Never lose a single camera frame – Surveillance HA is a software-only solution that supports two failover configurations, Server Cloning and Camera Pairing, for maximum flexibility. With Surveillance HA all previous recordings remain immediately available after a failover, business as usual.


Stability in the Face of Disasters

Maintaining a continuous, uninterrupted live stream of video footage is vital to organizations that have high intolerance to camera data loss such as airports, high security facilities, medical facilities, etc. With Surveillance HA live camera continuity is guaranteed even in case of disasters.


Data is Always within Reach

Quickly accessing previously recorded data may be vital to certain operations – for compliance and regulatory requirements, when investigating a security incident, or for dispute resolution. With Surveillance HA, all previous recordings can be accessed immediately. 


No Gaps in Recorded Footage

In the event of a network outage, camera malfunction, or other issue that results in the loss of video data, auto-backfilling ensures that there are no gaps in recorded footage. When the primary recording server resumes operations, the secondary recording server recedes in the background and any missing data can be backfilled to the primary server. 

Add Cloud-enabled Durability with Surveillance Bridge

Combining Surveillance Bridge and Surveillance HA allows for achieving unmatched availability, scalability, and durability. Storage extension to the cloud ensures that the current on-premises resources are optimized to last longer, which translates to cost savings and easier scalability. Keeping a copy of your footage and metadata securely in the cloud also provides instant disaster recovery capabilities.
