How exactly does that work when I see things like Price Example 1 and Price Example 2?
That's nothing on LTO-6

That's buying them one at a time, you could probably save a considerable sum by going through a vendor, and buying in bulk.
Probably because it's expensive.
The cameras that are being trialed right now cost like $600 apiece. That gets you hardware that's unintrusive, but only has about five hours of battery life at SD, and three hours in HD; plus it only has enough storage for six hours of HD video (source). Bumping that up adds cost and bulk to an already expensive device. But let's say someone does this, and it's $700 (probably $800, but let's be conservative). That's a cool half million just for one camera per officer. Of course, you're going to need more than that; gotta have spares on hand in case one breaks, malfunctions, gets damaged, wears out, whatever. So we'll round that up to $600,000 for cameras (which is also conservative, IMHO).
Then you have to find a way to store and log all that footage. So now you need additional storage space for all the data where nothing of note happens. So 800 officers times, let's say five hours a day (one hour to arrive, get briefed and orders, and get ready, one hour to get back and check in, and one hour for paperwork) times five days a week. At roughly 6MbPS that's 54 Terabytes of data per week. Now, I don't know about you, but to me 54TB seems like kind of a lot. I work in a video production facility and not that long ago we purchased a 48TB SAN that set us back like $56,000 (note: we were getting a discount because we were trading in some old gear, but let's stick with this number). Let's say that unless otherwise needed this stuff only gets stored "online" for three months, and is stored "offline" for three years (minimally; likely it'd be longer). So we need ~650TB of online storage, and at ~$56k per 48TB, we would need 14 units costing almost $800,000. Offline storage would likely be LTO, we'll assume it's LTO-7, which stores 6.4TB of data per tape, so we'd need 1,210 over three years. Now, LTO-7 hasn't been released yet, so all prices from here on out are for LTO-6, just as an FYI. A single LTO-6 tape costs ~$40, so 1,210 of them would cost close to $50,000. The cheapest LTO-6 drive is bout $2,300 and moves 1.45TB per hour. Moving a month's worth of video (we're not even talking about the ancillary data that would need to be attached to this stuff to make any sense) would take over six days.
So $600,000 for cameras, $800,000 for online storage, $52,300 for offline storage, and we haven't even gotten into the infrastructure to support all this. You can probably chalk up another $100,000 worth of networking and cooling gear (this stuff gets hot).
And this isn't insignificant IT stuff. You're going to have to hire someone to handle all this ingest. And someone's going to have to go through all five hours of footage generated each day and log the stuff. So we have to expand the payroll so we don't end up with unmanageable backlogs. I don't even know where that'll come in, but over the course of three years it'll probably cost more than the equipment.
You can get even cheaper tapes, $42 for 6.25TB / $17 for 3TB

And it's not even horribly slow, up to 160MB/s transfer rate, the only problem is the drives that read the tapes are prohibitively expensive for home use.
