With increased storage needs and faster processing requirements, how can an integrator be sure their video solutions are the most cost-effective, without sacrificing video quality? With interoperable products, an integrator can easily choose from more than 13,000 products to create the best possible combination of components for a video system. ONVIF establishes an interoperability framework through profiles – such as Profile T, for advanced video streaming, H.265 video compression, and bidirectional audio streaming; and Profile G, for edge storage, search and playback. The concept of profiles – or groupings of related or commonly used features – enables end-users, system specifiers and designers and integrators to more easily identify features supported by a specific profile. For example, knowing that a product is Profile T conformant tells integrator that it will work with another Profile T device for streaming video and audio, and supporting PTZ functions – without requiring in-depth technical knowledge of the product. The freedom of choice to select the most appropriate camera or NVR for the project, and to ensure that future additions to the video system will continue to be compatible with existing equipment, is one of the key benefits of using conformant products. When an integrator, for example, installs one brand of fixed network cameras to monitor a client’s office lobby and then uses PTZ units from another manufacturer in the parking lot, there will be confidence that the Profile T-conformant products will interface appropriately with the Profile G-conformant video management sys-
