for DVR, RAID 5 has high capacity and guarantees
data security. One set supports four SATA hard drives,
making the total capacity upto 2TB( 1TB = 1,024
GB). It can support more than one set if required.
In addition, a special function allows to replace
the failed hard drive with a new one without system
shutdown. RAID 5 is the ultimate DVR external CCTV
storage. |

the cost-effective SATA hard drives to achieve high
performance and data security. Advanced RAID-On-Chip
(ROC) technology takes cares of disk mirroring,
rebuilding and data protection function. It provides
LCD operating interface to make system setting convenient.
Also, it supports hot swap both in host and device
interface to save your data from accidents.

**Guide
for choosing CCTV Storage solutions |
|
What
is RAID Technology?
A RAID is a "Redundant array
of Independent Disks", a set of standard commercial hard
disks which the operating system sees and treats as if it
were a enormous single logical hard disk. In their simplest
form RAIDs use either a striping( RAID-0) or mirroring( RAID-1)
format in storing the data. RAID-5 is the configuration of
most interest for CCTV applications. RAID-5 is largly implemented
by airport operators, banks, casinos, logistics companies,
a road toll operator, power stations and town centers.
What
is Video compression?
Through
Video compression digital data recorded by DVR can be compressed
and saved in special hard disk which can be reviewed later.
Video compression plays an important role in overall operation,
properly compressed video can also save disk space. All DVRs
use some kind of compression algorithm called a codec to keep
the digital video files at a manageable size.
