Maximizing storage space. New disk-based technologies provide more options to store video in IP-based systems. Video can be stored at the edge of the network, for example, on a local DVR/NVR attached to the network, where even high-bandwidth, real-time, full-motion frame-by-frame video can be stored without having any negative effect on network bandwidth capacity. Alternatively, there are multiple technology choices to store video at a central location, including SANs (storage area networks), RAID (redundant array of independent disks) and iSCSI (Internet small computer system interface). These technologies provide flexible options for high-capacity network-wide storage. Various system design strategies enable users to employ the storage configuration that fits the specific needs of an application. For example, high-resolution video could be used locally to preserve forensic video evidence for possible use in a court, and lower-resolution video could be sent across the network to enable real-time response. Alternatively, lower-resolution video could be captured routinely with higher video frame rates and resolution triggered only in case of an alarm.
Management and video analytics software are changing the landscape. Perhaps the biggest development affecting how video and integrated security are being designed and installed for gaming operations is a direct result of new software applications. New management and control software delivers functionality and interoperability between previously unrelated hardware and software that is simply not possible with analog. Integrated systems tie many facets of video and security with point-of-sale systems, HVAC systems, elevator and people movers, lighting and more. Software-based systems offer so much versatility that the topic is simply too vast to cover in this article. The bottom line is that software-based systems need to be evaluated when considering a system enhancement or new installation. The economies of scale and scalability simply change conventional TCO evaluation criteria and models.
It’s worth the time and effort to take a critical look at new network technologies and how they best apply to your specific needs. You may quickly come to the conclusion that your investment pays long-term dividends.
