Without metadata, municipal area. For larger cities that could be at the street or building level, for out in the country it’s wherever your ISPs trunk or fiber breakout is.

With metadata, often times right to your front door. With the isps metadata absolutely to your door.

You won’t. When you loosen the stem bolt it’ll come up but it needs to go down so loosen it up maybe a half inch or so then hit the bolt head with a hammer. If you’re worried about messing up the bolt face then put a board or something on top of it and hit that. I used to use an old copy of glens complete bicycle manual as a go between for stem bolts and a four pound sledge.

E: it’s not always clear what’s going on. The stem bolt can keep the stem tight because the stems “base” (the part inside the tube) is cut through diagonally. The part at the bottom is what the stem bolt is actually attached to so when you tighten the bolt the part at the bottom slides out against the rest of the stem and becomes really tight inside the tube. When you loosen it it’s supposed to relieve that tension and become loose but actually it’s rusted in place so you gotta clink the bolt head with a hammer before the stem will come out.

Yank the stem. Loosen the bolt up then hit it with a hammer so it goes back down and pull the stem out.

2017 and previous airs and 2016 and previous pros have replaceable storage.

If you’re doing surveillance of people for extrajudicial reasons, constantly need to report crime or are just slurping up all the images of what goes on around your location for some project then it might be useful.

For responding practically to sudden and unexpected crime, dumb game cameras are the goat. They’re cheap, completely self contained, simple, relatively camouflaged (at the very least they’re not a black dome or a hooded ptz up in the corner) and when you need to turn footage over to the cops you can give them the “originals” (the sd card) and keep a copy if they require the originals.

the reason I didnt address anything you asked earlier is because I don’t think people generally need this crap and it’s probably a mistake for me to have explained how a person can make semi decent decisions about rolling their own.

Ram doesn’t matter. You can buy more, yes even when it’s expensive. The reason it doesn’t matter if that your needs will vary wildly based on your workload. I don’t know your workload so I can’t recommend an amount of ram. Maybe start with 16gb for a few cameras and a zpool based storage.

You want an old server because consumer hardware has no pcie lanes and is in general designed around a short duty cycle which is how you get such great “efficiency” numbers out of consumer equipment compared to a computer designed to reliably run 24/7. Of course your computer isn’t using any electricity, it’s not fucking doing anything.

The os doesn’t actually matter. Just use whatever you can keep running reliably. If you need to ask what you can keep running reliably then buy an off the shelf solution.

Don’t use proxmox or some hypervisor. The whole point isn’t to have a cool hackerman surveillance room with a bunch of screens like in the movies, it’s to have a reliable record of what your cameras captured. Fewer things to fail is better.

If you need to ask if a raspberry pi is appropriate then a raspberry pi is not appropriate. That’s true in all situations but here’s why it’s true here: you would only use a sbc for this application because you either don’t have anything else or you’re worried about energy consumption. If you don’t have anything else then it doesn’t matter if it’s a smart choice and if you’re worried about energy consumption then you’re not factoring in the energy cost of maintaining a place for a human being to exist and look at the screens attached to the pi or you havent considered simply turning off the terminal when it’s not in use.

Don’t do an ip camera based security system as a learning experience. What you will learn is that it was a big waste of time and isn’t practical.

I would recommend you think critically about what you’re trying to accomplish first and foremost then implement the simplest system that has the fewest points of failure.

Apologies for the account change, credential rolling schedule waits for no man.

Yes, it’s device firmware.

Again, if you would like a more practical approach based on the experience of being robbed I will gladly volunteer it.

Yes. It all works by default. The ones you want to use for a cache device are m10, they come in 16, 32 and 64gb sizes.
