Does anyone have first hand experience on how many times a class 10 SD card can be written over before failure?
I've heard a specific camera manufacturer claim 10,000 - though I've yet to see this in print from Sandisk

I'm sure B Karas has more empirical data from SD manufacturers but everything I've heard and read indicates SD (even high endurance) is not designed for the rigors of "eat the tail" cyclical recording demanded by video surveillance. Alternately, SSD is much more suitable for cyclical overwriting without the spinning disk point of failure.
Data sheets indicate writing alarm events to SD. I don't understand the benefit.
SD appears to be suitable for network fault tolerance (write to SD on network connectivity loss to server) but not a whole lot more.

Gday All,
I think I should suggest that peers look at exacqVision EDGE .... its precedes 2014 and provides a full customisable balance between centralised and de-centralised topography for video systems.
I've had to deal with competing manufacturers and integrators claiming they can do same. Zzzzzzt you cant.

Is it possible a new survey can be run on on-board storage capabilities. A lot has happened in 3 years.
