In this video, you'll learn how to protect yourself from AI spy gadgets that can literally see through your walls. Technologies like Xaver can detect people inside buildings from as far as a football field away, using advanced sensors to track movements in real time. The video compares Xaver to other spy tech like Range R, Ground Penetrating Radar, and Thermal Imaging Cameras, all of which raise serious privacy concerns. To keep your privacy intact, you might need to consider hiding behind metal sheets or walls, or even using foil as a barrier. It’s a wild world out there, but with the right knowledge, you can stay one step ahead of the spies.
00:00Putting up curtains to give you some privacy at home has not been enough since the Xaver 1000 was invented.
00:07This gadget might look like a weird camera, but it is actually a next-generation radar explicitly designed to see through walls.
00:16Yep, just like a superhero.
00:18But its power is to visualize objects hiding behind obstacles and show you a 3D model of them with exceptional resolution on a touchscreen display.
00:28Now, you might be wondering how this technology can imagine what's going on inside your house.
00:35Okay, maybe imagine is not the best word choice, since it is much more precise than that.
00:42This technology uses radio waves, and one thing we know about radio waves is that they can pass through walls,
00:48which is also why we can talk on our smartphones inside buildings, or use Wi-Fi to transfer data from one room to another.
00:56So, while radio waves can penetrate walls, they don't make them transparent.
01:02That is why the Xaver 1000 can only generate an image of what is inside a building, but not show you the exact real deal.
01:10After all, it's not some hidden magical camera.
01:14When the radar waves from the Xaver 1000 hit something on the other side of a wall, like a person, a dog, or a television, they bounce back.
01:22The device catches these echoes and uses them to create a picture of what's behind the wall by making a smart image reconstruction in 3D, using AI methods.
01:33What makes this technology super interesting is how detailed the picture can be.
01:38I mean, it's not just a vague blob.
01:41You can actually see where people are and how they're moving, whether they're sitting, standing, or lying down doing nothing.
01:47Plus, it can also tell the height of any object.
01:50This makes it incredibly useful for rescue teams.
01:56Firefighters, for instance, can be situated at a safe distance from dangerous surroundings and scan a large area quickly.
02:03They can see if anyone is trapped inside a room on fire without having to break in blindly.
02:09The Xaver 1000 was particularly useful during last year's earthquake in Turkey,
02:14helping locate trapped survivors and guiding rescuers to their exact locations.
02:19Although this gadget is mostly used for good, you might be wondering if someone could spy on your house with it.
02:26And yeah, in theory they can.
02:28But there is one thing you can do to prevent that, making the Xaver 1000 pretty useless.
02:33So, radio wave devices can penetrate almost any type of wall, including cement, drywall, plaster, brick, and even reinforced concrete.
02:41However, they can't penetrate through metal buildings or walls lined with metal or foil.
02:48This is because metal reflects radio waves, just like a mirror reflects light.
02:53And that means that all the energy emitted by Xaver 1000 will be blocked.
02:57In fact, the strange way metal reacts to radio waves is exactly what powers those high-tech scanners you see at airports.
03:07You know, the ones where you stand still, raise your arms, and a machine spins around you?
03:11These fancy scanners use something called Advanced Imaging Technology, or simply AIT,
03:18which sends millimeter waves through a passenger's body.
03:21When you step into the scanner, it emits electromagnetic waves that bounce off your body and anything you're carrying.
03:28So, no, people who control these machines can't see inside the body or through the skin,
03:33which means they can't detect things like tampons.
03:37But if a passenger has something dangerous in their pocket, the machine will spot it.
03:42And that includes any dangerous metal objects.
03:45Like I mentioned earlier, metal reflects radio waves,
03:50so that means it behaves differently compared to how waves interact with fabric or skin.
03:55These reflections help the scanner pinpoint the location of dangerous objects on a basic outline of the human body.
04:03In recent years, similar technologies have made significant breakthroughs.
04:07For instance, in 2020, a device called Ground Penetrating Radar unveiled all the mysteries of the ancient Roman city called Valeriae Novi.
04:18This city, located approximately 30 miles north of Rome, is partially buried.
04:24But thanks to the Ground Penetrating Radar, we now know a lot about it.
04:29Valeriae Novi had a population of around 3,000 people,
04:32and it boasted an elaborate public bath complex, a market building,
04:37at least 60 large houses, and a rectangular temple with columns near the city's south gate.
04:43All of these hidden secrets were discovered and mapped out in just about four months.
04:48And they managed to uncover everything so quickly because they didn't excavate it with machines and shovels.
04:54They scanned it.
04:55That's right. Ground Penetrating Radar is widely used in archaeology
05:00because it can detect and map buried structures and artifacts without the need for excavation,
05:06which can be expensive and time-consuming.
05:10This radar operates similarly to devices like the Xaver 1000 or body scanners used at airports,
05:16enabling it to see through things.
05:18It works by emitting pulsed radar signals into the ground via a radar antenna
05:23and then detecting echoes that bounce back from objects.
05:28Discovering ancient Roman cities may seem distant to us,
05:32but similar technologies are much more present in our daily lives than we realize.
05:37Take self-driving cars, for example.
05:40They have the ability to see their surroundings by detecting obstacles, pedestrians, and other vehicles.
05:46This capability is made possible thanks to a technology called LiDAR,
05:51which uses lasers to emit pulses of light at incredibly high speeds
05:56to measure distances through a process known as time of flight.
06:00So, these laser pulses are emitted by this device,
06:04and when they hit an object, they bounce back to the LiDAR sensor.
06:08The system calculates the time it takes for each pulse to return,
06:11predicts locations and distances,
06:13and then creates 3D maps of the whole environment.
06:17These maps include details such as buildings, roads, and other vehicles.
06:22This information is then combined with other data,
06:25like the speed limit, to ensure safe navigation during the trip.
06:29Next on our list of technologies with a sixth sense is hyperspectral imaging.
06:35Imagine a camera that doesn't just capture the usual red, green, and blue colors,
06:39but instead captures hundreds of different colors across the entire light spectrum.
06:45This includes wavelengths invisible to the human eye,
06:48such as infrared radiation, ultraviolet rays, and even x-rays and gamma rays.
06:54A hyperspectral camera goes beyond what we can actually see
06:58by breaking down light into numerous bands, or slices, of colors.
07:03It separates light into individual wavelengths, or spectral bands,
07:08providing a two-dimensional image of a scene that reveals important and hidden information.
07:14We can use this technology in many different ways.
07:17For example, have you ever wondered how your fruits and veggies
07:20stay fresh and perfect in the store?
07:22That's because hyperspectral cameras can quickly scan and analyze large volumes of food products in real time.
07:31This device measures ripeness, conducts mold inspections, and even detects contamination.
07:37The idea is to reduce food waste while ensuring that only the best-looking
07:42and best-tasting products reach your local grocery store.
07:46Thermal imaging cameras work in a similar way,
07:49and they help keep our homes warmer, especially during the cold months.
07:53Think of these cool gadgets as detectives that spot invisible clues about energy,
07:58showing where your home loses heat or lets in drafts.
08:03What thermal imaging cameras do is detect infrared energy emitted by all objects based on their temperature.
08:10This energy is invisible to the human eye,
08:13but these cameras can see it all and translate it for us using an infrared detector.
08:17The camera's software processes the captured radiation data and translates it into an image.
08:24You know, I'm talking about those weird pictures that show how hot or cold things are.
08:29Different colors indicate different temperatures,
08:32with red typically representing hot areas and blue indicating cold.
08:37In short, you just have to point these cameras at windows, doors, and walls of your home
08:43and let the thermal images show you where the cold air is sneaking in.
08:47But it is a good idea to call a technician to help you with that.
08:52That's it for today.
