Reddit mentions of WD Red 1TB NAS Internal Hard Drive - 5400 RPM Class, SATA 6 Gb/s, CMR, 64 MB Cache, 3.5" - WD10EFRX

Assuming retail price, and using comparable scale operations, I have a revised estimate of $3.1B (2TB storage), keeping the rounding consistent, $2.8B 2.5B startup, and $ 350M 300M (number includes replacing 1/3 cameras per year as well) a year for resources and replacement drives. Another user pointed out a viable option, utilizing pre-existing data farms and paying ~$10 per GB, although I am unsure of the feasibility on this scale. The last cost to figure out is the cost of data transmission. Keep in mind, this wouldn't be a one, five or even ten year project. This would take many years, but this is to show the viability of such an operation undertaken at this point.

If any cops out there want to give an estimate of what percentage of officers are actually on patrol and what percentage work at the station or in any other way don't interact with the public while working, it would help to revise the numbers a bit more. Not every one of the 1.1M officers needs a camera.

If someone could figure out how much it cost for CARI cloud storage to build their data centers, and what their capacity is, we might be able to come up with a figure for LA.

Why would it be? Just the cost of memory? It would take 1Tb to store a 650hr 720p video (MPEG 3.7Mbps, perhaps there is a preferable format). So you could get basically a month of footage stored in "HD" on a one terabyte drive. I'd assume for the sake of redundancy and security, you'd want to store them in a RAID setup, so we'll make it 3 1TB drives (Western Digital Red for the sake of this calculation). *Larger capacity hard drives would be cheaper per TB, but 1TB drives makes the math easier. *Enterprise storage would cost about twice as much for twice the amount of storage (2TB for $135, 4TB for $250).

Each one retails for about $60, although I'm sure buying in bulk would net you a decent discount, but we'll use that number. So 360=180. Each officer can get a month of storage for $180 a piece. A Google search which references Wikipedia states that there are 1.1 million officers in the US. Assuming every single one of those is a patrolman or otherwise out in the field, it would cost $198 million just for storage. Add on the cost of cameras and you get somewhere in the range of $700 million (using $500 as the figure per camera).

Revised estimate of storage cost is $445.5M, not $198M. Package cost is then ~$1B

Another quick google search for police brutality settlements puts the number at $185 million for NYPD, $84 million in Chicago (with a cited half a billion over the last decade), Baltimore ~$10 million in settlements and legal fees. The LAPD paid out $54 million. Oakland paid out $3 million. While this is a small number of cities, you get the idea. Lawsuits are costing a lot more per year than the cost of a monitoring infrastructure. For these five cities alone the cost is ~$340 million.

While recording devices may not stop all claims against the police force, it definitely makes cases a lot more open and shut, no one can dispute photographic evidence. The assumption is that cameras increase the accountability of not only the police, but also of the general public; no one wants to be on camera acting like a madman.

All in all, the cost of recording devices, software and infrastructure may seem like a lot, but with the amount polices forces around the US are paying out in lawsuits, the cost doesn't seem as great. Even if the difference is negligible, the increased trust in the police force, and introduction of a system of accountability for officers seems worth it, for everyone.

Edit: An additional cost would be the cost of erecting cell towers or deploying mesh network solutions. If you're going the cell tower route, the average cost is ~$250,000 per tower. I can't find much information about the bandwidth of a cell tower, only that upload speeds per client can support the video bit rate. If you can figure out the total bandwidth a cell tower has, or how many client devices one can support, another piece of data can be added. Another thing to keep in mind is this rollout would in no way be able to happen within a few years, it is a multi-decade project, and hopefully the cost of transmitting data falls, as well as the cost of storage and processing of the data 10TB SSDs within 5 years will surely bring down prices

Edit 2*: Another thing to put the number in a better context is the cost of the actual facilities. The Provo, Utah data center is reported to store between 3-12EB, it cost $1.5B to build, and an annual operating cost of ~$50M. If every officer (which I will restate, is way overestimating, maybe police officers of reddit can help me out with an estimate of the percentage actually on patrol) is given 1TB of storage with 2 backup drives, the storage capacity is roughly equivalent** Screwed up here, should be the value of 9 hard drives to get the equivalent, depending on which end of the spectrum the capacity of PUDC lies. The number of employees is also lower than I had expected. There are 200 permanent employees of this data center.

Using that figure as a rough estimate for the cost to run such an operation, we can take the initial startup sum of $2.5B (rounding up from $2.2B). Assuming the cost of electricity and water is the same for both, and that 1/3 harddrives fails and needs to be replaced per year, the annual operating cost is ~$300M. Then the last question becomes the cost to transmit the data, which I am still trying to work on.

Self hosting. One of the easiest ways is probably with a synology nas or similar product.

Has pretty much everything you need. You can install gitlab on it, or you can install individual components you need (apache, php, git, mantis bug tracker, etc)

The upfront costs are a bit high and disks are sold separately.
I assume you have to search for a local seller though if there's a trade embargo going on.

I say the benefits outweigh the costs though:

• You can simultaneously use this as general file storage and your project host. You can limit access the way you like.
  
• Has lots of packages, installation of things like VPN server or other components is pretty much "point and click"
  
• Two disks for redundancy (using software RAID 1)
  
• You can SSH into it
  
• No monthly costs apart from power consumption
  
• Not having to trust a 3rd party with your data
  
• Not depending on a 3rd party upholding their contract
  
• Can connect to PPPoE networks (DSL) and cable networks when configuring the ISP supplied modem as bridge, acting as your modem/firewall. This makes port forwarding unnecessary.
  
  The only real downside of self hosting is that it depends on your internet connection. You have to forward ports and if your internet is down, your collaborators can't reach your service. This is less important for git but other things they might want (issue tracker, files, automatic builds) will be inaccessible.

People swear by the WD Reds so: https://www.amazon.com/Red-1TB-NAS-Hard-Drive/dp/B008JJLXO6

With the Nas you selected having 4 bays, I would get 4 and put them in raid 10, this would give you 2 tb of space for growing room, as well as a backup in the event a drive fails.

Ended up slightly more than your original build but I think you'll appreciate it.

Motherboard isn't red but comes with red LEDs. If you want a red motherboard then the MSI B250M GAMING PRO is cheaper.
B250s only support up to 2400MHz RAM and the Ripjaws V is really red. But if you still want the LEDs, the 3200MHz Corsair Vengeance LED is a pound cheaper, though it would send you closer to £900.
The CS1311 isn't as good as an 850 EVO but it's cheaper and has a red line going through it.
Not a lot of red HDDs unfortunately. There's the WD Red 1TB​ NAS Deskt​op Hard Di​sk Drive but it's only 5400RPM. There's also the WD Red Pro that is 7200RPM but doesn't come in smaller than 3TB.
Black and Red RX 480.
A cheaper black and red NZXT case. You could also take a look at the Phanteks ECLIPSE P400S TEMPERED GLASS (same price) and the NZXT S340 (Black/Red) (cheaper).
Not a lot of red power supplies either.
Monitors with red highlights are usually the high refresh rate ones, like this one or this one. Look around and take your pick.
* The cheapest red and black keyboard and mouse combo on pcpartpicker was the Redragon S101 Wired Gaming Keyboard w/Optical Mouse. Don't know too much about it.

I was able to get together a black/gold build. A little more subtle than a red/black setup.

Comments:


1. Half of the products are cheaper on Amazon.
2. The CPU cooler will be stock (the H80i is just too expensive for this build) however, it seems like you aren't looking at overclocking immediately. The stock cooler can always be replaced later.
3. After the rebates you might be able to get the H80i.
4. I had to go with a Micro-ATX setup to fit your budget. You won't have an SLI option in the future but then again, you are looking at a 780 Ti.
5. The 350D is quite open and will provide ample room for expansion.
6. The Newegg 780 Ti is black and fits the color scheme.

I don't want to tell you you are stupid, but I really would not put a file server on an old laptop like that. (said with kindness and sympathy)

If you are relying on these files, or these are the only copies, you will want brand new hard drives. Even if you are the risky kind, one day you will regret it when your laptop inevitably dies or the hard drive corrupts.

A classic DIY method is buying an old desktop (with preferably 8gb but 4 is fine) and replacing the hard drives (WD Red are IMO the best). There are heaps of tutorials on doing this sort of things, an example here. Though a single new drive isn't perfectly safe, unless it's life or death files you should be fine. However you can look into RAID setups or local backups (nor are these perfect, but they are closer)

As for which software I can't really help you. It really comes down to opinion and needs. Some NAS software lets you access files from a mobile app, some don't. My personal favourite is FreeNas and I don't even know why. Good luck on your endeavour, hope I could help

Great, so I think I'm going to go with:
