Managing the migration from analog to IP

Much has been written about the migration from conventional analog video surveillance systems to an IP networked based platform. Depending upon specific system requirements, both analog and IP systems have advantages, and in-between there is the alternative of a hybrid system which can deliver the best of both worlds, while providing the flexibility to enhance or expand your system as the need arises. But, there are many additional criteria to consider before a decision can be made when designing and building a new system or upgrading an existing system.

According to industry research, IP networked systems currently represent approximately 10 to 20 percent of the total installed base of new and revised systems on an annual basis. This clearly indicates that there is still a tremendous demand for analog systems and products. More importantly, it means that systems product manufacturers need to continue to develop new technologies and products for analog system applications because these systems will still be in place for some time; and at present conversion rates, they’ll continue to represent the majority of systems implemented for several years to come.

Simultaneous to continued analog new product and technology developments, there is rapid development of more advanced IP networked systems products -- particularly in the areas of increasing image quality and PC-based control solutions -- given the inherent benefits of IP systems. Additionally, the trend towards integrated and enterprise level system operations can occur only with IP networked based systems, as a common software platform is required to deliver true interoperability for otherwise disparate applications such as access control, intrusion detection, visitor management and life/safety systems.

Add the trend to integrate additional facility systems, such as point-of-sale, HVAC, lighting, elevator and escalators, and the need for a common software dashboard becomes essential. There’s also a growing trend for mobile monitoring and control capabilities that requires a common software interface (otherwise referred to as middleware) running on an IP networked platform.

The decision to move to an IP networked platform does not have to be black-and-white. Hybrid analog-IP systems provide a highly efficient means of bridging the gap, while capitalizing on the benefits of both technologies. In addition to allowing you to expand your existing analog system, hybrid system expansions allow you to add infrastructure in those physical locations where none currently exists. Hybrid systems also allow you to connect different physical locations for centralized monitoring through placement of satellite systems that can operate both independently and as part of your converged system set-up. This provides a great deal of flexibility and efficiency, while providing a foundation for migration to an all-IP based networked platform in the future.

The key to determining what is right for your needs lies in identifying what combination of systems, products and platforms works best for you today, while providing a platform for future enhancement and growth. Professional systems integrators and installing dealers are a good resource for consultation, and many training and educational programs are in place within the industry to ensure that these integrators and dealers stay ahead of the technology learning curve.
