Dual Mode Video Management System
IP cameras are becoming more prevalent in today's market. The need to monitor and record traditional analog cameras side-by-side with IP cameras is also increasing. Integral Technologies offers one of the most innovative dual-mode (hybrid) recorders on the market today. DigitalSENTRY 3.0 provides a better solution than simply connecting multiple analog to-IP and IP-to-analog converters to a DVR. With an Integral Dual-Mode Digital Video Management System (DVMS), the IP camera and server are directly and seamlessly interfaced to any DS Enterprise or DS XPress system.
Integral Dual-Mode DVMS allows you to: administer and monitor analog and IP cameras using the same interface; simultaneously search and export video from analog and IP cameras; link audio sources to both analog and IP cameras; easily add IP cameras to an existing analog system; and increase camera counts on an existing system.
Licensing a DS system to become a Dual-Mode DVMS makes the rich feature set of the DigitalSENTRY 3.0 software available to IP cameras and video servers. Also, because licenses are purchased individually, the total cost of the system is based only on the system requirements?there is no need to purchase licenses for an IP device that is not attached to the system. This provides the most cost effective system with the lowest total cost of ownership available today. Visit www.integraltech.com for more information.
A Line of Network Video Recorders
The JVC VR-N100U line of network video recorders provides a networked solution as well as an advanced camera management system. The VR-N100U-600 and VR-N100U-1320 provide simple configuration and management of large-scale, IP-based security systems comprised of up to thousands of security cameras?both analog and digital. The first practical and cost-effective, completely digital IP network video recorder, the VR-N100U enables companies to considerably expand their surveillance systems to meet their growing needs, without requiring additional investments in network bandwidth.
Featuring a digital recorder and Web server in one package, the JVC VR-N100U combines video cameras communicating over an Ethernet IP network with digital recording and network control. Although specifically designed to work with IP network cameras, the VR-N100U can be integrated with analog cameras using JVC's optional VN-A1U(A) network encoder, preserving customers' investments in legacy systems.
The VR-N100U stores all individual camera data locally and acts as a server, managing IP cameras on a sub-network. Systems designed with VR-N100Us eliminate a serious and potential drain on network bandwidth as only video from the requested cameras is transmitted at the network level. Each camera attached to the VR-N100U can be custom programmed with recording options based on priority, individual frame rate, individual resolution and more. Only images from priority cameras are then transmitted via the network, unless specifically requested from another video data recorder. An alarm function alerts the operator to changes in status of cameras so that nothing is missed.

Bringing It All Together
By maximizing existing analog investment while taking advantage of IP-based video, installed systems can be expanded to further protect people, property and profits. For users of video security technology, having an IP migration strategy has become critically important. Given the increased presence of IP-based video security products and mandates from corporate CFOs to take advantage of already-existing network infrastructure capabilities, an eventual move from analog to IP technology in some form or another is inevitable.
Rather than signal the end to analog systems; opportunities are emerging in this dynamic field to seamlessly combine both analog and IP systems for a powerful, video security solution. In fact, today's analog matrix switcher technology not only works, it works well and will so for many years to come. Analog continues to represent a viable and secure investment in proven technology that can be expanded to meet the growing needs of a particular installation.
Through convergence, the combining of two distinct systems to form a new one, a hybrid system offers new ways of expanding systems and improving the benefits of video security. Pelco is harnessing the power of convergence to offer a manageable and effective video security solution and is also among the leaders in the design and application of hybrid solutions. Pelco offers a comprehensive line of cameras, programmable domes and positioning systems. To take advantage of IP capabilities, Pelco has developed and implemented a strategy using external analog?to-digital conversion devices that enables the use of these powerful cameras in both analog and IP environments.
With its PelcoNet Series of video transmission devices, Pelco brings to your fingertips the IP world without the unnecessary investment in new, IP-only cameras. PelcoNet Series converts an analog video signal into a digital video stream that can be placed onto a network with ease.
The Pelco Net300 and Net350 are two such video transmission devices. Designed to sit on the "edge" of a network, they directly connect to a camera via coax and receive its video signal. That signal is converted into a high-quality, MPEG-4 video stream, which then exits the device via an RJ45 Ethernet connector. This process gets the video onto the network, which can then be accessed by Pelco's browser-based software.
Once on the network, it is critical to be able to record and store that digital video stream. The Pelco NVR300 is a rack-mountable, network appliance that recognizes, decodes and records digital video data. With an internal hard drive capacity of 500 MB to over 1.5 TB, the NVR300 can also be accessed from Pelco's browser-based software.
Designed as the nerve center of an analog/digital hybrid system, the VMX300 Video Management System connects to monitor outputs on a matrix switch as well as to a network via Ethernet. An intelligent system, the VMX300 recognizes and decodes digital video signals and recognizes recorded video from an NVR. It also recognizes recorded video from the Pelco DX9000 digital video recorder. To complete the "hybrid" strategy, it recognizes the matrix switch and can communicate with and control connected analog cameras.
While taking advantage of existing network infrastructure can provide a powerful hybrid solution, the question of what happens during a network interruption or failure is a fair one. Pelco has considered this possibility. Its solution is the Net350 Automatic Data Replenishment feature. In the event of a network interruption, this Compact Flash compatible card will record and store video and upon network restoration, it will automatically communicate with the NVR and relay the missing video information. This is done as it continues to stream live video. Also, the analog matrix switch continues to operate and provide control to operators via the matrix keyboards.
By placing video on the network, there may be some questions as to bandwidth utilization. To that end, the PelcoNet Series of video transmission devices allows users to adjust the amount of bandwidth used. This bandwidth-throttling feature means that streaming speed and video quality can be reduced, thus lessening the impact on the network.
