And that’s why hardlining is still by far the best option available.

  1. Hardlined cameras need to be physically accessed and the cables snipped in order to disrupt them, and most cameras offering hardlining now feed Ethernet through their bases, providing additional protection.
  2. Most sub-20 camera systems can run for up to an hour or two on a 500VA UPS, and up to a week or more with PowerWall backups, defeating intentional power outages.
  3. A fully airgapped system can defeat any sort of direct Internet intrusion.
  4. Shielded Ethernet can help protect from crosstalk attacks provided they are correctly grounded with the appropriate switches.
  5. Hardware auth between cameras and the DVR can help defend against direct attacks via an unplugged cable or an open wall jack, in that only approved hardware can make the needed connections with either end.
  6. Encrypted communications between cameras and DVR can enhance the security of data across the wire.
  7. A brace of identical dummy cameras - similarly powered, if they have external indicators - alongside real ones will waste the time and effort of attackers who conduct physical attacks, while keeping recording-infrastructure needs to a minimum.
  8. Bonus if identical but “dark” Ethernet is similarly spoofed throughout the building, as not only will it confuse physical attackers, but it’ll also be already in-place for future communications-infrastructure improvements.
  9. DVR needs to be in a secured location, ideally fireproof. In combination with № 7 and № 8, a dummy DVR (with live screens showing actual content) can exist elsewhere to distract any physical attackers.

Sure, this list isn’t 100% coverage, but it gets you nearly there with a minimum of effort.

You have some interesting ideas about what a minimum of effort looks like

[–] [email protected] 2 points 9 months ago (1 children)

If you are in the middle of a frame-off gut of a home, as I currently am, much of this is trivial to implement.

Even my parent’s 1978 home, with it’s drop ceiling in the basement, would not make most of this all that much more difficult.

A notoriously low-effort endeavor in itself.

"It's doable with a minimum of effort as long as you have your house gutted down to the foundations" isn't exactly the shining defense of "a minimum of effort" that I expected to read

Go in your attic for 20 minutes. Throw some Ethernet around. You don't even have to plug all of it in lol

[–] [email protected] 12 points 9 months ago (1 children)

I had to buy almost $500 of mdf to get around my attic well enough to pull cable for backhaul. It's not as easy as you make it sound in a lot of cases.

[–] [email protected] 0 points 9 months ago

You only need 2 pieces and some creativity.

[–] [email protected] 7 points 9 months ago (1 children)

Not all attics are that accessible. Mine is basically an above-house crawlspace full of insulation such that you need a mask.

[–] [email protected] -3 points 9 months ago (2 children)

It's 2024, do you not have a mask

[–] [email protected] 3 points 9 months ago (1 children)

No, I’ve used them all up in the last 3 years

[–] [email protected] 2 points 9 months ago

They made more.

[–] [email protected] 1 points 9 months ago (1 children)

Requires a different type of mask, but yes, I have many masks of different types.

[–] [email protected] 1 points 9 months ago (1 children)

And would you describe it as challenging to wear, there one or two times you would need to be in the attic for this task?

[–] [email protected] 2 points 9 months ago* (last edited 9 months ago) (1 children)

  1. You have completely missed the point of attics not always being very accessible in order to argue for no good reason.

  2. Yes, I would. The respirator type mask which you require in that environment is very stuffy and tough on someone like me who has a lung condition.

  3. It being tiny makes it more inaccessible than the need for a mask does. The opening into the attic is narrow. I can fit through it, but most Americans would not be able to. Once up there, you have to crawl. I have a medical condition affecting my muscles which makes it exceedingly difficult to crawl.

Point is, once again, that not all attics are accessible. This isn't a discussion about masks.

[–] [email protected] 1 points 9 months ago (1 children)

Obviously if you have medical conditions there's limitations.

[–] [email protected] 1 points 9 months ago (1 children)

Going with "your experience doesn't count because you're a little different" is not the winning argument you might want it to be.

[–] [email protected] 1 points 9 months ago

When discussing a general situation, one is not obligated to write off every possible situation.

A person without medical conditions can navigate an attic, even if tight, and requiring a mask. That's not revolutionary.

minimum of effort

yeah, nah, they can just have my stuff.

Right, and always remember they’ll go for the easy win first. First choice is likely walk in an unlocked door, then kick in one not visible from the street, or if you really want in, break a window.

The thing is, even if you get a good shot of the person doing it, it probably can’t help find the person, only prove that it was them, if you find a suspect.

A better use is to get that early warning of what is happening as soon as it happens, and get a response going, but what’s the response time from your local police department? A smash and grab gets them on their way with your valuables, with very little chance of police getting there on time

That’s when we’re back to physical security and it may not be what you think. Can you reinforce your lock plate and door jamb to make it difficult, noisy, and time consuming to kick in a door? Are there windows they can easily get in and what can you do about that? Are there hidden places where they can break in without being seen? If a light suddenly comes on or alarm goes off, will they leave in case someone looks?
