Subject: RE: [emergency] Response from David Ellis - Video in <derefUri>


CCTV would be the first systems any intelligent attacker would 
take down.  They are useful and vital, but vulnerable.  They 
do die.

The use of an artificial representation is necessary to backup 
the CCTV sensors to enable Cursor on Target style coordination.  Maps 
and simulations work if they are reasonably current.  The CONOPS 
has to handle degrading sensors and isolated resources.

From: Elysa Jones [mailto:ejones@warningsystems.com]

Please forward to the mailing list.  The alerting framework already can
handle video without operational impact.  The "publish and subscribe"
nature of the framework minimizes the delivery of unwanted messages.

Also, the normal XML messages from sensor systems is usually extremely
short do the limited processing capability and power budget of the
devices.

This being said, the use of the <derefUri> for sending detection data
from special purpose nodes (e.g. sensors or sensor concentrators) and/or
private networks which are unreachable from the "Internet" is the best
way to get this data to a general purpose computer.  This is only way to
publish the detected data.  This detection data is usually stored in a
local tactical data base for not only emergency use but to be retrieve
periodically to develop base line data and State of Health of the large
network.

The video issue is very real.  We continuously struggle with the Concept
of Operation issue (CONOPS.)  The use of video to assess whether CBRN
sensor detections are real versus a false alarm and to assist in first
and emergency responders command and control is critical.  Cameras do
not die but people do when exposed to CBRN events.  The problem is who
really need to see the video data.  When the Four star general and/or
the civilian equivalent wants to monitor the response in real time it is
hard to tell them no.  This may be something which will be solved by the
EDXL standards work.

I would be very interested to talk with committee members who have
experience with this type of CONOPS problem.
