We do a lot of work for Walmart, which in loves camera evidence.

Each store has 50 +cameras. Think of the data being captured in their 10,000 stores. That’s 50,000 recorded hours every hour.

Let’s say they’re using basic HD, that’s 1 gig an hour. So they’re recording and saving 50TB per hour. That’s A LOT of data.
