The storage space to store the 500 surveillance cameras video channel for 90 days?
What such information is necessary to store the video data at this point? I want to be able to easily access, organize and store. If I compress and the video quality is exceptional, so my recovery will be of the same quality?
When I use video capture XviD4 @ 15 bpp and it takes about 250MB for a 40min show. So 6.25Mb leaving a minute. This includes mp3 audio to be recorded at 190kb, so they are probably looking actually closer to 5.5 MB per minute. You can also use a less bpp, I use .15 because I realize no loss of quality. Anyway. 5.5MB x 60min x 24 hours x 90 days x = 500cams even if audio capture high quality 356.4TB although this is about 405TB. When I spoke to compare the quality Image of DVD 15 I see no distortion of video and is virtually identical to the original. Now the hard part; equipment. This an enormous amount of data, if they were to build a storage system using the latest technology and bigger hard drive (Seagate 750GB of storage perpendicular) required 534 Sperate hard drives to 750GB each $ 420.00. Or later this year that Seagate launched its 1TB disks then you need 400 of them. Now, if you can move data to tape can reduce the number of units and also very size of the recording system. You do not have to invest in a very expensive and very fast backup to tape, and can last up to $ 3000.00 or more. These units you can use the backup tapes with capacities of 800 GB or more, and these tapes cost about $ 150.00 each. With 800 GB of tape that needs 500 to Shop for 90 days. One thing is to realize that the video is already compressed, otherwise it would be Hugh. So do not pay much attention to the straps compression values. So the best option for building a system is to have a system with more than 10 TB of disk space, it is possible. Want this amount to be able to record video a day, then transfer all the data on videotape during the recording day following (you want the software to 24 hours of video for each camera.) Another thing to consider is that you are recording about 4.5TB per day, which amounts to 188GB/HR. Although it is Hugh probably want units to be ready in groups 2 and RAID 0 Drive, just to be on the side safe. This is useful when you try to access data in this day and time of data transfer. For the rest of the computer (CPU, MEM, etc.) you want a system effective enough. Top of the line CPU and memory all that can be arranged. You also need to purchase equipment which can encode video on the fly. No computers, with the exception of computers called Super possibly can that the quantity data encoded on the fly. Encryption is a process very intense and with a dedicated hardware can even put in modern systems. Your organization's knee and the file will be easy enough just to develop a monitoring system of bands of color and / or serial number. Part The question is who is to receive the camera inputs. This will depend largely on your environment. Well I hope this helps out.
