Digital Video Systems Overview
• A digital video system is any combination of
the different components
• A system is defined by the actual devices and
their deployment:
–
–
–
–
Central based, pure DVR-based system
Central based, hybrid DVR-based system
Distributed, encoder-based system
Distributed, IP camera-based system

Head End Options
• At the head end, the user can choose how to
view, playback and control the video system
• The different environments where video
systems are installed require different user
interfaces:
– PC-based software
– Multiple viewing options
– Virtual matrix controller
VICON A&E SUMMIT

PC-Based Software
• Is installed and runs as an application window
or several of those on a PC
• Offers various tools for viewing and control of
the video over the system
• Allows seamless usage and control of any
device on the network
• Is limited to the actual PC screens and
performance capabilities

Multi-View Options
• Some users want to be able to view all or
many of their cameras all the time
• This opens the following questions:
– How many cameras on what size monitor?
– How many monitors can a PC drive?
– How many cameras can be viewed effectively?

Virtual Matrix Controller
• Allows switching and displaying the digital
video sources on analog monitors like a legacy
matrix
• Uses video decoders to take the video “off”
the network and out to an analog monitor
• A strong platform allows seamless usage and
control of any device on the network
• Allows a “monitor anywhere” approach and
takes advantage of the network

Open Platform
• What is open platform?
– The ability to accept many to any IP-based video
into the video management system
– Allow 3rd party cameras to be used in the
ViconNet software
• Specific for ViconNet
– Keep supporting our own “build for security”
cameras
– Support all cameras on same GUI

Open Platform “Challenges”
• Every camera comes with a different set of
supported functions
• Camera update will probably require ViconNet
to update
• A lot of these cameras are browser-based and
offer a less secure path than proprietary
protocols

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
• We assume that the system we are integrating with
the video system notifies the video system of those
events and the video system displays

JAN. 25-27, 2009
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

Dry Contact
• A simple switch

Serial Host Protocol
• Sends commands over serial connection
• Video system responds accordingly
• Main integration method with analog matrix system
– Advantages
• Reach 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

What is an API?
• Application Programming Interface
• Set of routines and data structures provided in
order to support building applications
• Usually an abstract set of code that needs to
be used by the developers to make functions
work (include in their code)

What is a SDK?
• Software Development Kit
• Set of tools to allow certain access to certain
functionality
• Comes in many shapes and forms
– ActiveX download
– Tool to include items in web page
– Tie in to a system

API and SDK Integration
• Software-based interface
• Software tools to allow access to video
• Many forms and options (no standard)
– Advantages
• Bring video from anywhere into your application
• Very flexible
• Usually not a physical connection (uses network)
– Disadvantages
• Requires writing computer code
• Requires on-going support and updates

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

Video Analytics
• An optional software package
• Solution for intelligent video analysis
• Per-channel set of pre-defined behaviors are
being monitored in real time on the video
• Automatic identification and alert of defined
behaviors
• Key feature for event-driven monitoring
VICON A&E SUMMIT

JAN. 25-27, 2009
How Does it Work?
• The video system is integrated with the video
analytics module providing it with “material” to
analyze
• Video is analyzed to alert of specific events
• Alarm events are sent to the monitoring
application screen
• Graphical overlay on the video will highlight the
actual person / object detected for this event

Enhanced Analytics Integration
• Enhance the integration between the CCTV
system and the analytics engine:
– Transparent communication
– Graphical feedback on live and playback
– Common user and alarms interface
Analytics is value-added to video and
represents a growing need

Analytics Reality
• Many misconceptions and myths
surrounding the capabilities of the software
• First items to consider:
– FAR – False Alarm Ratio
– NAR – No Alarm Ratio
– Ease of use
• This is a support tool for the system
operator and needs to be easy and intuitive
