In a city council last month, Chicago's Office of Emergency Management and Communications was pushed to answer questions about how they know if cameras are working or not and how often. The emergency management director's response was that they should expect a 2% failure rate with cameras in a surveillance system. He called it "pretty standard in the industry." So it that right? End users should be ok with a two percent failure rate?

Nov 20, 2013Like a 2% failure rate per year? Are we talking just about the camera or any point that could go bad in between that would cause the disconnect of a camera?

Nov 20, 2013A two percent failure rate "on any given day." So if you randomly sample the cameras every day. Expect 2/100 to be down. They didn't give specifics, but I'm assuming they mean it's either not recording or not providing an image (for one reason, or another).

Nov 20, 2013That's a weird metric because how many are down on any given day depends on how fast they are fixed and how often they break. Let's assume it takes a month to fix a camera (that's long but use it as a rough starting point). That would imply that 2% of cameras break every month or 24% break in a year. We need better clarification / statistics to assess.

Nov 21, 2013Actually taking that long to fix isn't nearly as long as it takes to get paid by most governmental units.

Nov 20, 2013Interesting reading Carlton, a lot of cameras 22,000!, without a lot of oversight...
Most likely the Director meant a 98% availability rate, meaning the % operability of all video paths from lens to lcd/recorder. Obviously this includes non-hardware items (firmware, VMS setup, storage) and no doubt some of this issues linger longer than a typical hardware repair cycle.
The weird thing it seems they are just saying 2% as a predictive measure not as though they a reporting their actual metric.
Kinda like "pick a camera, any camera these are the odds it's working"
Best quote:
There is “no way we can monitor 22,000 cameras” at once.
Scariest quote:
"Ald. Deborah Graham (29th) noted that OEMC is forging partnerships with major retailing chains and downtown businesses to gain access to their surveillance cameras. Graham further noted that those private cameras are being closely monitored by a public-private task force."

Nov 25, 2013I would say test because not matter how foolproof or great tour system is there will always be a snag in the system that will cause issues to be fixed now if ur software and daily check ups are down you most likely will be able to avoid this
