For example if five dedicated external NVRs were to be deployed, then the installer could eliminate these five NVRs by running the applications on the storage hardware already deployed. Here’s a breakdown on the cost comparison:
|Comparison||DAS||Clustered NVR SAN||Savings|
|Dedicated NVR servers||5||0|
|Server cost @ $3K/server||$15K||$0||$15K|
|Server power & cooling||5KW||2.XKW||44%|
|Rack space @2U/server||10U||-0-||10U|
In today’s cost-sensitive environment, those integrators that manage the infrastructure costs of video surveillance bids will provide more competitive bids and retain higher margins. Using a camera simulator allows integrators to run performance tests with the actual NVR application, determine maximum performance, and more accurately estimate retention times. The use of clustered storage can also help by reducing over-provisioning and simplifying re-allocation of capacity and bandwidth in the field. The latest implementation of clustered storage also eliminates dedicated NVRs.
