Video Security Design Workshop: Event Driven Displays for Video Management Systems

Learn about the integration of low voltage systems based on events and different methods such as dry contact, host protocols, and SDK/API. Discover the advantages and disadvantages of each method and examples of their implementation. Find out how to create an open event management system for easy correlation of cameras to events, video pop-ups, search tools, and report generation. Explore the next generation of integration with communication back to sending systems and control capabilities from the video management system.

  2. Integration • Integration of low voltage systems is a much desired feature • Often based on events • Ways to integrate systems • Dry contact • RS-232/422/485 and host protocols • SDK and API • Integration involves linking events from other system with video from the video management system, allowing for easy viewing of video that corresponds to events.

  3. Dry Contact • The oldest trick in the book… • The integrated system provides a dry contact on each event while the video system responds accordingly • Advantages • Simple 1 to 1 design • Available even in legacy technology • Disadvantages • A LOT of wiring • Distance issues • Larger system usually don’t have enough contacts

  4. Dry Contact • A simple switch

  5. Serial Host Protocol • Sends commands over serial connection • Video system responds accordingly • Main integration method with analog matrix system • Advantages • Rich protocol-based solution • Most legacy systems are already created to work with analog matrix • Easy to implement and maintain • No need for programmer • Disadvantages • Control is from integrated party to video • Requires dedicated cabling • Limited to the protocol

  6. Examples • Dry contact: • Legacy intercom system, added video and wants a camera to show the door • Host protocol: • Detention touch screen-base system to control the video switching • Access control events to trigger video • API and SDK • Detention touch screen to show video on the touch screen itself • Integration with building automation system to show video in the MI interface

  7. Integrated System – The Advantages are Obvious! • The difficulty is in getting the two parties to agree on the integration and communicate through the process • Many cases end up with no results

  8. Create an open event management system The Solution: • Provide simple tools for: • Correlating cameras to events • Video pop-ups for specific terms like “access denied” • Allowing search of events and calling playback video • Supporting report creation Allow receiving events from systems, regardless of their nature XML IP Provide a common communication protocol, such as IP and XML

  9. Getting XML event from 3rd party Access control

  10. Correlating Cameras to Doors

  11. Configure Response to Event

  12. Provide Reports and Search Tools

  13. Next Generation • Current open event management system solves many of the integration issues • Next steps will be: • Offer communication back to the sending system • Control from the video (unlock doors, open gates)
