Digifort Professional and Enterprise versions support failover function.
If server A is not working then server B will start recording all cameras and answer to events. Once the problem have been solved with the main server (Server A), then Digifort’s service will stop on the Failover server (Server B) so that the cameras can stop recording.
Indigo Vision supports failover servers, as our installation proves.
Genetec offers failover both on the Directory(login authentication, system information) and Archiver (video recording) Failover. These do require additional licensing beyond the base, but both are straight-forward to setup and work really well. We have seen Directory failover times under 2 minutes from shutdown of primary, and Archiver failover in under 1 minute.
Avigilon supports simultaneous and failover recording with the enterprise version of the ACC. You need to have licenses available for this funtion to work on the spare servers.

Video Insight VMS includes automated Failover so long as a physical or virtual server is designated as for that role. It monitors any live servers, and inherits the cameras from any failed server. Once a failed server is back online and restarted, all cameras back to their normal server. No licenses beyond the live cameras are required.
Aimetis Symphony supports automatic failover and load-balancing in Professional and Enterprise versions. No extra licensing is required above the camera licenses (e.g. no add-ons whatsoever). With our architecture, we purposely do not have any sort of hierarchy of servers. N+M failover is supported, however by combining management and recording across all physical servers in the “server farm”, the customer only needs 1 extra failover server rather than one for the management and one (or more) for the recording servers. The servers communicate status between themselves without the need of having another server dedicated to this role. Any one of them can also handle logins. Finally, many VMS vendors require Microsoft Clustering to eliminate a single point of failure at the “head-end”. We do not require this since client traffic isn't going through any sort of "head-end".

Milestone Coorperate supports failover.
All their servers are run from the master server which then pumps the configuration of the failed server, to the failover server.
Verint Nextiva also supports failover for recording servers and for Master database
Pelco’s Endura solution is built so that the System Master (SM5200) can be operated in a failover configuration. Additionally, now available is a new solution called Multi Failover, where SM5200 boxes can be deployed at geographically disparate locations and be configured to assume primary responsibility for the devices and clients at that location if the network link to the primary goes down for any reason. Pelco’s Network Storage Manager (NSM) solution also focuses on redundancy by deploying the recorders in pool configurations where any member can be promoted to the Master, should the master fail.

Geutebruck's G-SIM addon package supports failover. You can designate another live server or have a standby server waiting. They also have a from-the-factory certified Windows cluster setup offering.
DVTEL's Latitude supports failover and redundancy.
