INSIGHTS
The advantages of HD over SD are evident, but even after two years of “evangelization,” issues that hinder the overall performance of HD surveillance systems still linger. Transmission and storage are complex but easily resolved when enough money is thrown at the problem. Things are a bit different on the management and display side, where manufacturers still have a bit of work to do to optimize the software and hardware for better visibility and increased interoperability.
Stepping Back From the Edge

Interoperability and Implementation
Video technology is moving from proprietary to standardsbased solutions, Lakshminarayan said. “There are many advances that have driven manufacturers to either comply with these standards or publish APIs to ensure that their products integrate with the existing multipurpose systems. Mix-andmatch has become very common as these video systems grow to satisfy a multitude of business goals and requirements.”
However, with all the promises of interoperability out there — ONVIF, PSIA and HD-SDI — “truly open” systems are still simply not there yet. Even HD-SDI, which is supposed to provide true plug-and-play functionality and analog simplicity, is plagued with incompatibility issues among brands, which were highlighted in the September 2011 issue of a&s International.
That said, current standards do indeed guarantee at least some level of interoperability and peace of mind, and they are constantly being improved. If customers follow standards, they reduce the possibility of facing future compromises, Wilson said. Vendors whose products comply with these standards can be found on the respective websites of the various organizations.
HD in security video surveillance has quite a few obstacles to overcome before it matures. While some are psychological factors, there are also some very practical issues to be resolved, Ying said. ”Installing plug-and play analog surveillance systems requires little more than hard labor. However, simple as it may seem at first glance, configuring IP addresses and selecting software GUIs require more technical skills that are currently lacking in the average security installer.”
