Tony, this survey report is applicable: On-Board Storage Usage Statistics
[I work for Samsung]
I have numerous small retail applications - typically 4-6 cameras per store. Sometimes a store will have only 1 camera. They don't want to put in a server or manage licenses, or stream 24x7.
Edge storage is a great solution for them. They pop in an SD card, and then use the included free SmartViewer software.
They can then view onsite or offsite (using DDNS if on the internet vs. corporate WAN) live & playback from there.
We did a roll out of a nationwide store allowing their HQ to view each store, as well as the local manager.
As long as high quality SD cards are used, things went well.
I have also used this scenario for remote locations where there are a few cameras inside a small building (power utility building, etc.) and/or outside. Because of the remotness of the site, they don't want to deal with additional equipment.
Front entrances of communities. Cable runs back to a central source are cost prohibitive. If we have any source of power, and there is usually something, storage on the edge is the answer. They don't need it all that often and when they do, they usually know it right away (within 24 hours). Property management retrieves the card and the rest is downhill. Digimerge SyncroIP.
You should look into Mobotix, they pioneered the technology. I have many installs that go 3 to 5 years before an SD card fails. It is not usually the cards fault but how the cameras utilize and store the video on it. I have also used Dahua and have had about an 80% success rate, but the cards fail more frequently. When we reformat the failed card and install it in a Mobotix camera it usually works fine. Based on our own experiences we only offer edge recording With Mobotix now.
We have used this concept extensively at community entrances and community pools.

Exacq would have to be, We're not using in any mass quatity but in the few sites it works very well. Make sure you check their camera compatibility chart first.
You can record at 3 megapixels at full frame rate continuosly about 4 1/2 hours of video to a 32 gb SD card with audio. So if you set the camera up at 7 frames per second and use only motion recording using the Mobotix MXActvity sensor you can record 2160 events at 30 seconds each. If you use a 64 gb card that would double. So depending on the application environment this could be several days to a months worth of recording.You can also extend the recording even further by reducing resolution to 2 or 1 megapixel if the applications does not need 3 megapixels.
