Contemplating about integrate recognition into a surveillance system...

Hi there, great work.
I am developing a surveillance system that using face recognition service on smart edge devices that directly send back the captured face images.
There are about 4 smart IPC working at the same time(even more than 16 in the future),capture average 4000 face image per day(about 1000 image per camera per day), consume about 137GB storage per day.
The recognition algorithm I am using cost about 1.7min to execute the search.
Are there any other viable product that using this framework could provide me some advises. thx
