DVR cards

The DVR card looks to quite similar general computer videocard in many PC. However, when business reaches functioning, there are many distinctions between them. The DVR cards go with the software, which can be used to show and make a data recording from repeated chambers at the same time. They are established in computers to allow them to function as system of digital video (DVR).

The DVR cards are mainly used in supervision systems to process information received from a source, such as the chamber and to transfer it to the data storage device as a hard disk. In such adjusted there is more than one video a port. In these ports production from chambers of video surveillance is included to the card. After established in the computer, the card becomes active and is immediately recognized as car thanks to the accompanying software. After properly established, this card allows the user to make in a digital form entry of signals on the hard disk and then to consider it instantly.

Depending on requirement you can choose quality of storage also. Ranges of frames per second (foot a second) the DVR cards equal 30, 60,120,240 and 480. fps also defines time during which record can be made. For the hard disk having disk space on 80 GB, in 30 foots a second, it is possible to make record within 320 hours. In the same way in 120 foots a second, for a hard disk on 80 GB, it is possible to make record within at most 80 hours. If you have a hard disk on 960 GB, you can make record for beating of 3840 hours at the rate of 80 foots a second which translates to 160 days or nearly 5 months.

Only the limited number of chambers is supported by the old DVR cards (began nearly two years ago). If more chambers were necessary, more cards should be established. It led to increase in working loading of the computer which was incapable to satisfy to the requirement of memory and led to system accident. Modern cards go with the expanded built-in computing capacity which reduces burden on the computer.

With unsurpassed features of the DVR card of profit to symbolize very necessary technological intervention in supervision and control area. In the next years, with advantages, the DVR cards completely will replace his ordinary competitor.
