Actually, all security cameras tends to have an IR filter by default, otherwise colors will be off. Better surveillance cameras will have a "movable cut filter", meaning a mechanism to remove the IR filter from the light path to t

In short, there are too many different kinds of approaches to AI in surveillance cameras to have a universally effective camouflage. In many cases there is simply not enough pixels on target for these patterns to render in a way that makes

This wouldn't do anything useful in real-world scenarios. Source: I've been heavily involved in AI security cameras for the last decade+.

For the most part, very little. They have recently entered into an agreement with Yamaha outboards[1] to have Yamaha manufacture Sharrow propellers. So far though there has not been much in terms of real-world validation of the props on com

So far in unbiased real world tests the efficiency gains have been fairly limited,and. It enough to offset the increased costs. Note that I mention unbiased tests. There are some manufacturer tests comparing a boat with essentially a wrong

Interesting, what city is that in? FWIW, I was describing the end to end transit experience. Moving undesirables from a bus or train to a waiting area is not really solving the problem. Similarly, having waiting/boarding areas that are

IMO, transit also needs to be clean, reliable, and crime-free if you want to actually see it utilized. Otherwise you are just pushing poor people to an unsafe and inferior transit option that adds other challenges and issues. Like being con

Why not DIY it? Particularly with "minimal expenses", it's really just math for what you are describing. Almost any tax software package will be able to handle what you describe.

This is super interesting, but why are people posting this kind of thing to tweet streams? Twitter is just absolute shit for trying to document this kind of research, IMO.

"Real" AM/FM radio has gong to shit in most markets anyways. Tons of advertising for traffic lawyers, diet pills, donut shops, etc. DJs talking too much, limited playlists. I think "AM/FM" radio is really jus

"On a regular basis" may not be quite the level occurrence, but yes, it does happen, and it often will not become a news story when it does. As others have pointed out, some states like California have laws and enforcement policie

(Anonymous)Visitors is not a very useful or valuable metric. Blindly pumping content into the ether isn't going to convert to value, or cashflow. I think we are seeing the advancing erosion of (generic)ad-supported free content and ser

It’s very common for the recording server to have some kind of WAN/internet connectivity in larger scale systems. At a minimum the recording server usually has access to other internal networks. Would be possible to execute something s

Is the suggestion that they come shipped from the factory with code to compromise common recording servers? Yes. While I have not seen it happen yet, there is plenty of precedent in cyber warfare tactics in general to have trojaned devic

What do you mean no one has seen? There are many documented vulnerabilities in Hikvision cameras: https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=hikvision

The "put them behind a firewall" approach is really not adequate. Many times these cameras are already behind a firewall of sorts, larger CCTV system will use a dual-homed server, with a dedicated LAN for the cameras, and a second

No, that is not likely to happen. These bans have been developing for quite a while, based on continuous proof of major cyber security flaws in the products, and documented human rights abuses by Hikvision (and Dahua). Several other CCTV ma

Avigilon, Axis, Hanwha, and i-Pro/Panasonic all manufacture their own products. There are many good choices for non-Hikvision or non-Dahua cameras. The Hanwha A-Series is very cost competitive with the Hikvision stuff, and from a far m

Automakers rate things like panel gaps on an X of 10 scale, where X is on average how many people have historically complained about a gap of a given size. Some thing are rated as maybe a 3 of 10, and they won’t overly obsess on it, but som

How you can transfer bitcoin between exactly two people with zero outside involvement from other entities? I suppose you might be able to have a bunch of pre-filled wallets of various amounts that you can transfer via thumb drive, but in a

Which by definition is fundamentally impossible to do transfers without a middle man of some kind.

The birth of the stock market also created new avenues for fraud that did not exist prior. Right, but I've never heard anyone say in response to stock market fraud, "You know what would fix this? A stock market!" The logic

Blockchain may fix it, but couldn't we also argue that blockchain created these problems in the first place? I will fully admit I have only casually followed the whole blockchain/crypto scheme, so maybe I'm wildly off on some

There was a good amount of talk about "perfect information economics", which before the internet had only been a crazy idea, but then suddenly seemed like something within grasp. I'm not sure if there was ever a real belief t
