Event Driven Displays for Video Management Systems

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

7. 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

8. 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

9. 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
Create
an open event management system
XML IP
Provide a common communication protocol, such as IP and XML

10. Getting XML event from 3rd party Access control

11. Correlating Cameras to Doors

12. Configure Response to Event

13. Provide Reports and Search Tools

14. 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)
