  • Cameras are everywhere.

  • Wherever you go, you're always being watched.

  • Except on airplanes!

  • Why are there no cameras in the cabin?

  • And which places are watching you, but shouldn’t be?

  • Youll want to know this!...

  • 1) Why are there no cameras on airplanes?

  • The real question is, why would there be?

  • CCTV cameras are installed to monitor order in stores, banks, hospitals, and similar public

  • places.

  • If something happens, you can call the police or rescuers.

  • In an airplane, the crew keeps order.

  • If something serious goes down, there’s not much they can do, and not much a camera

  • will help with.

  • Plus, eye-witness accounts from plenty of surrounding passengers serve the same purpose

  • as a camera would.

  • Since cabin recordings aren’t needed, why spend money on CCTV?

  • 2) Is the same true for all forms of transport?

  • Of course not – I’m sure youve seen cameras in subway cars, buses, and trams.

  • These types not only record needed proof if something goes wrong, they can also recognize

  • faces!

  • A great asset for catching bad guys!

  • They also send geolocation data to control centers so that help can be dispatched ASAP.

  • But the coolest thing is that some cameras are installed in the driver's cab.

  • It can detect the slightest signs that the driver is falling asleep or feeling unwell.

  • 3) Where else are CCTV cameras used?

  • If you live in a pretty big city, youve seen them everywhereon roads, telephone

  • poles, almost every building entrance, in the park, on trees.

  • It looks like global surveillance, but there are pluses to this.

  • Any person can contact the main center where all these videos send their footage, and theyll

  • get recordings if any incident occurs.

  • 4) Can you watch the live footage?

  • Sure can!

  • There are sites where you can access many city cameras even in other countries!

  • You can watch what’s happening on the other side of the globe just like that, through

  • your computer.

  • One filmmaker even made a whole movie just from footage taken by real city CCTV cameras!

  • 5) How do cameras see in the dark?

  • They don't, actually.

  • There's no night vision device that will work in absolute darkness.

  • But if there's a small source of light that the human eye can't notice, then the camera

  • will record it and show this through that famous green image.

  • The camera converts invisible (for humans) objects in the dark into visible ones using

  • special optic lenses.

  • Then it adds brightness and contrast so that your eyes can pick it up.

  • 6) Who’s watching you without your knowing, and what can you do to stop it?

  • Unfortunately, there are cases when cameras are installed where they shouldn’t be by

  • law!

  • Whether youre renting an apartment, staying as a guest at someone’s house, or in a hotel,

  • you can’t always count on people to be honest.

  • So, check the place for hidden cameras:

  • Let’s start with the bathroom and bedroom.

  • Statistically, secret cameras are most often installed there.

  • Some have been found inside hotel showerheads and even tiny cameras hidden within the coat

  • hook on the stall door of a public restroom!

  • Your phone can help you do a thorough search, but more on that in a bit

  • Study electrical appliances carefully.

  • Smoke or motion detectors are popular spots.

  • Hidden cameras may not be visible, but you'll recognize the lenses.

  • Don’t forget the furnitureshelf corners, cabinets, near the bed.

  • Even a superficial inspection can detect them.

  • Check small details: lampshades, picture frames, clocks, and the most popular: the

  • eyes of plush toys.

  • Even if you didn't find anything, you can cover up suspicious objects with a patch or

  • chewing gum.

  • Ok, now get out your phone.

  • Let’s give this room an even better scanning that your eye might not have caught

  • Turn on the flashlight, and move it slowly around the room.

  • The camera lens will shine a little, and you should be able to spot the glare.

  • The front camera of your phone can see infrared radiation.

  • Turn off the light, close the curtains, and walk around the room with the front camera

  • turned on.

  • If a hidden camera is installed, then youll notice a small flash on your phone screen.

  • Modern cameras can be smaller than a fingernail, making them next to impossible to find.

  • But you can at least disrupt their work.

  • For example, using a Wi-Fi jammer, you interfere with the network and the signal to the camera.

  • And if you know where the WI-FI router is, you can simply turn it off so that the camera

  • loses the signal.

  • You can also check out the App Store for programs that help you find cameras connected to WI-FI.

  • Finally, be extremely careful around ATMs!

  • Offenders can install cameras in or around them to see your PIN.

  • Whenever you punch in your number, always cover the area with your other hand.

  • But hold on, nowyoure not done yet

  • 7) It’s not just cameras you should be worried about!

  • Two-way mirrors are used instead of CCTV cameras in plenty of places, even when they shouldn’t

  • be.

  • The name is a bit misleadingthe observing goes only one way: anyone on the hidden side

  • sees you, but you can’t see them!

  • When used properlylike interrogation rooms and grocery stores, these mirrors create

  • a real observing system that will work even when the power is out.

  • When theyre hanging where theyre not supposed to belike public restrooms,

  • store changing rooms, and hotelsthen youve got some more detective work to do:

  • Check out the wall first.

  • If the mirror seems to just be hanging on it (versus being built into it), then it’s

  • probably ok.

  • Turn out the lights, and try to peak into it.

  • You can also shine your phone’s flashlight into the mirror.

  • If there’s a secret room on the other side, then you might get a glimpse.

  • You can also knock on the glass.

  • A room behind the mirror will produce a “hollowsound.

  • The most famous is the fingernail trick: put your finger on the glass like youre

  • pointing at your reflection.

  • If there’s a small gap between your fingertip and its reflection, then it’s probably just

  • a standard mirror.

  • If there’s no gap, then it could be a two-way mirror!

  • (Try the other tips to be sure!)

  • But back to CCTV

  • 8) How do modern home surveillance cameras work?

  • The short answer is through Wi-Fi.

  • That way, the recording can be tracked in real-time, from any devicephone, computer,

  • tablet.

  • And if the signal and image disappear or strange movement is caught, youll receive an instant

  • alert about this to your device.

  • People install cameras not only to protect their house from thieves.

  • You can keep an eye on your pets while youre away, or check that the babysitter is doing

  • their job!

  • 9) If you want a home security system, how can you choose the right camera?

  • You should pay attention to several things: – The camera's hardware: it needs to withstand

  • high and low temperatures if you install it outside.

  • The viewing angle and focus: the larger the focus, the better the picture quality,

  • but the smaller the viewing angle will be.

  • With a wider viewing angle, quality goes down.

  • Your best bet is to settle somewhere in the golden middle!

  • Camera sensitivity: it should recognize objects even in the dark.

  • The price: obviously, you get what you pay for.

  • You can find high-quality cameras for thousands of dollars.

  • They have an impeccable image, to the point youll feel like youre watching a movie,

  • not a CCTV recording!

  • 10) What if you can’t spend money on cameras, but want to protect your home?

  • - You can take a chance and use a fake.

  • A thief can be scared away or a person may behave more correctly when they see a security

  • camera, whether it works or not.

  • In fact, some of the cameras you see in stores, on the street, in hotels, the officethey

  • could be fake because everyone wants to save a buck!

  • - You can use your phone and computer webcam as a CCTV camera system.

  • There are special apps that activate them from a distance.

  • Suppose you want to check if everything’s okay at home.

  • You open the app on your phone, and it shows you the picture that the laptop camera records.

  • And there’s Fidobeing a good boy, as always!

  • Hey, if you learned something new today, then give the video a like and share it with a

  • friend!

  • And here are some other cool videos I think you'll enjoy.
