I would say fixed cameras last forever if you are happy with the picture you are getting.
In terms of failure rates, I think it depends on too many factors to meaningfully give a single metric (e.g., where the cameras are deployed, what type of camera, who the manufacturer was, etc.).
15 year old cameras 'seem to be doing the job'. 1998 vintage CCTV cameras? I'd be curious to see what the image now looks like.
I'm curious about the infrastructure. With the advent of Ethernet over coax, cables could potentially be deployed for many years and different technologies. Are there any "rules of thumb" relative to the cabling, etc...
IMO, the largest contributing factors to surveillance system lifespan are environmental exposure (wind/rain/humidity/extreme temps, etc) and having/not having a regular scheduled maintenance plan in place after installation.
Anyone agree/disgree with those two? What else drives failure in your experience?
I am in need of more than just a converstion here. Is there a Life span/cycle document with a recommended replacement age. If I can't find something like that the money people will make me run them until they die. I would rather budget for a annual refresh of a certain number but need hard facts to back it up.
