Home and Business Security Systems are chosen depending on the immediate security needs, at the time the installation is done. In some instances, property owners may decide to add some features that might not be needed at the time, but are likely to come in handy in future. However, security demands change with time, and even the best security camera system will require expansion or upgrading to meet these new demands.

Adding Extra Storage - Why is it necessary?

After installing CCTV surveillance systems, property owners may decide to make changes to the initial installation such as adding more security cameras, adjusting the video recording quality,security camera system long island or extending the period for retaining surveillance footage. Making any of these adjustments will affect the storage requirements of the security camera system, and thus necessitate expansion of the storage capacity.

How to add extra storage

The CCTV system design is a crucial factor in determining if a security camera system can support extra storage capacity, as well as the type of storage that can be added. Below is a look at some of the common designs and how storage capacity can be expanded for each.

Embedded DVR: Modern analog camera systems use digital video recorders(DVRs) with internal hard drives for storage. If users want to expand the storage capacity for this setup, they simply remove the existing HDD and replace it with larger-capacity disks.

Directly-attached or remote RAID: These two storage options are commonly used with IP surveillance systems. Users have two main options for adding storage capacity:

  • Horizontal storage: Users can simply attach new disk arrays to their network switch and configure the NVR to send some of the video streams to these disks for storage. With this approach, the users have to manage multiple RAIDs independently, since each disk array is separate.
  • Vertical Storage: Alternatively, users may choose to expand their base units by adding simpler RAIDs. By doing this, the users will expand the existing disk array's capacity. This approach is easy for users to manage since the daisy-chained RAIDs are treated as a single storage stack, and require only one IP address for monitoring and management.
