Comparing storage methods. Divar and DiBos DVRs can both use direct-attached SCSI RAID.
The VIP X1600 uses the network to reach its storage – either a short direct network cable for
Direct-Attached Storage (DAS) or via a network for shared Network-Attached Storage (NAS).
Red lines indicate IP connectivity.
Why does Bosch Video over IP use iSCSI?
Bosch is using iSCSI in its latest VIP X generation of Video over IP technology for CCTV.

Flexibility Because iSCSI is IP network-based RAID can be located anywhere on the
high-speed network. This includes being share storage on the network
(Network-Attached Storage) and dedicated storage independent of the
network (Direct-Attached Storage).
Economy Because the IP cameras and encoders communicate directly with the iSCSI
RAID there is no need for a powerful NVR server, its Windows 2003 Server
OS nor the NVR management software (VIDOS-NVR). The solution eliminates
these components and is consequently highly cost-effective.
Reliability There are no NVR server reliability issues, which can include internal hard
drives, power supplies, fans and software.
Also, just like a DVR with a SCSI RAID, the VIP X1600 can use an Ethernet
cable to connect to an iSCSI RAID and use it as direct attached storage. This
means that video is recorded regardless of the health of the network or the
amount of available bandwidth.
Maintainability Since there are no NVR servers there no Windows OS patches or updates,
VIDOS-NVR updates nor virus updates to maintain.
Also because everything is IP-based and all support Simple Network
Management Protocol (SNMP), off-the-shelf IT applications and continuously
monitor and alert in case of problems.
Scalability Add more storage to the system by plugging more iSCSI RAID devices
anywhere onto your network.
