Matt, Interesting challenge. A couple of notes: One, OV 4 is some seriously out of date software, if you are running the analytics in MANGO unit you should be able to get an upgrade to 5.2 from them. If you are running on a server you may be able to get to v6.2 ( the Edge version of 6.2 is due out in mid 2014 Upgrading will help simplify rule configuration and increase accuracy in general - however, in terms of detecting fires, that is a separate challenge. While OV doesn't have a specific fire analytic, the only thing I can think of is to use the vehicle analytic and add a size filter to filter out anything smaller than a large truck - it wouldn't alert when a fire started but it would alert when the fire got bigger than a typical truck. Not ideal I agree, but perhaps enough to satisfy the customer. Let us know offline if you need help with configuring size filters
Warren, thanks for the help on Thanksgiving! Quite the customer support!
Matt, if you are looking to possibly propose a fire detection analytic, VCA Technology has this analytic filter. This would require an overhaul to the current setup, but it would give you a this specific detection type.
One additional thought based on the photos you posted - you may be able to use a people or vehicle rule with a large size filter to get reasonable accuracy... I take your point on being hard to test....if you have the clip from the fire and some clips of normal activity- OV may be able to run them through a test setup to see the results. Though it would be against the 5.x or 6.x library as we don't have an active 4.x system running.
Sorry to not have a more definitive answer for you - thanks for sharing the challenge though - gives our developers food for thought as we go forward.
