Connecting Storage devices
Images are recorded to the internal hard disk for instant playback and searching by the operator. The capacity
of the internal disk effects the amount of images and time that can be recorded.
For example, a 80GB unit can record for 8 days at default record rates, but a 320GB unit can record for 31 days at
the same record rates.
The internal hard disk is a temporary storage device as the images are constantly being overwritten after a
certain period of time.
If all images need to be kept for longer then external storage is required. The 50-way high density SCSI-2 port
on the rear of the unit is used to connect to external storage devices.
The unit’s operating system will continue to utilise the internal hard disks if the external hard drive encounters
a problem.
There are two types of external storage devices which can be used:
RAID
RAID units contain hard disks which adds to the internal storage, effectively extending the number of images
which can be recorded before being overwritten.
RAID units give protection if a fault occurs. If a disk fails in a RAID the images will continue to record to another
disk in the array. RAID also allows faulty disks to be hot-swapped – replaced whilst the RAID is powered.
JBOD
JBOD units contain hard disks which adds to the internal storage, effectively extending the number of images
which can be recorded before being overwritten.
Unlike RAID, JBOD units do not offer fault tolerance. Therefore, if a disk fails then the information held on that
disk is lost. The disks in the JBOD are not hot-swapable.
Connecting Multiple external devices
Up to ve external storage devices can be daisy chained from the SCSI port on the rear of the unit.
Each device must have a unique address and the last device on the chain must be terminated. Check with the
device documentation for details of addressing and termination and maximum cable length.

The table below gives capacity and typical uses of each storage device including the internal CD writer.
The table below shows the record time for typical record rates, using an 18K le size. These values can be used
when using the internal CD writer for additional storage.
Connecting to an Ethernet network
The unit includes an enhanced video server allowing remote connectivity across an Ethernet network. Multiple
users can connect simultaneously to the unit to view and control live or recorded video, download recorded
images or review database details.
