WHAT IS DVR CARDS?

A DVR card looks quite similar for the common computer video card in quite a few PCs. Even so, when it comes to functioning, you can find a lot of differences between them. DVR cards come with software that can be used to display and record information from multiple cameras at the same time. These are set up in computers to allow them to function as digital video recording (DVR) methods.

DVR cards are mostly used in surveillance systems to procedure the data received from a source such as a camera and pass it on to a storage device like a challenging disk. In such a set up, there is a lot more than one video out port. At these ports, the output from the security cameras is plugged in towards the card. As soon as set up inside a computer, the card becomes active and is instantly recognized by the machine thanks for the accompanying software. As soon as properly installed, this card allows the user to digitally record signals on to his tricky drive and then view it instantaneously.

Depending on require, it is possible to also choose the quality of storage. DVR cards frames per second (fps) ranges are 30, 60,120,240 and 480. The fps also determines the time for which recording is usually done. For a tricky disk having 80 GB disk space, at 30 fps one can record for 320 hours. Similarly, at 120 fps, for an 80 GB challenging disk drive, one can record for up to 80 hours. If you have a 960 GB difficult disk, you'll be able to report for a whopping 3840 hours at the rate of 80 fps, which translates into 160 days or nearly 5 months.

Only a limited number of cameras are supported by the old DVR cards (launched nearly two years ago). If a lot more cameras were needed, extra cards had to be installed. This led to an increase in the workload of the computer that was unable to meet the memory demand and resulted in a system crash. Modern cards appear with enhanced inbuilt processing power that reduces the burden on the computer.

With unmatched features, DVR cards have arrive to symbolize a much required technology intervention inside field of surveillance and monitoring. Within the coming years, with advanced features, DVR cards will completely replace its conventional rival.
