RAID 5 external storage for CCTV
 
Designed 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.
 
USB mirror smart instant backup system with LCD
 
An USB2.0 to SATA hardware RAID 1 Subsystem utilizes 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.
 
Hardware RAID-1 Subsystem
 
Ultra160 SCSI-to-IDE hardware RAID 1 Subsystem utilizes low cost ATA 66/100/133 hard drives to achieve high performance and data security.
 
Network Attach Storage [NAS]
 
This is a highly integrated system providing instant backup to preserve massive data. With NAS, files can be conveniently stored, retrieved, and managed through Local Area Network.

  **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.

What is average size of uncompressed video ?

Frame size Frames per second Space( Uncompressed still frame)
320*240 px 25fps 230400 Byte = 2.3 Mb( 24 bit color)
3.07 Mb (32 bit color)
Frame size Frames per second Space( Uncompressed Video for 1 hr)
320*240 px 25fps 25*3600* 230400 Byte = 20.736 GB (24 bit color)
27.648 GB (32 bit color)

How to save more data on small space?

  • One of the ways to reduce the disc space by sampling and recording the frames at lower than the full 25 frame per second rate. The combination of file size and storage rate will give a figure for storage capacity per second. for example: to store 30Kb file at 3.13 frames/sec requires 30*3.13= 93.9KB = 0.34Gb per hr
Quality Normal Good Better Best
25fps 128Mb 213Mb 297Mb 508Mb
15fps 76Mb 127Mb 178Mb 304Mb
10fps 51Mb 85Mb 118Mb 203Mb
8fps 40Mb 68Mb 95Mb 162Mb
4fps 20Mb 34Mb 47Mb 81Mb
2fps 10Mb 17Mb 23Mb 40Mb
  • Both YUV as well as RGB formats are possible for reducing the amount of size required to store the video signal.
  • Event recording is possible.
