They are also adding camera poles (that’s what I’m assuming they are) on the newest tables they setup a few days ago, and also more of those crowd control barriers.
Those video cameras would use up a lot of data. Assuming each one is 1080p resolution and records at 16 Mbps (2 MB/s.), each camera uses up 170 GB per day. 30 or so video cameras add up to 5 TB/day. Assuming one backup drive is needed for RAID 1, two hard disks are needed each day. Each 2U rack server can hold 10 hard disks, which means each one is good for 5 days. For 30 days' worth of data, 12U of rack space + 3U of networking/UPS space is required.

we need more storagefags like you!
Well done! But Rachel Mad Cow probably thinks....oh wait, no she doesn't.
Video is highly compressible.
I already took compression into account. The encoding quality could also be lowered down to 5 Mbps, but the picture looks grainier.
r720's can have 24 bays as well as some supermicro models
