The most unusual methods and unique inventions for protecting property.
Since ancient times, people have come up with various methods and devices to protect their home and property from attacks by strangers and natural disasters.
Today, scientists and inventors, using scientific advances and modern technology, have expanded ideas on how to make this world safer.
Security alarms using wireless technology, video cameras, GPS trackers and other devices that have already become commonplace are installed in most homes and cars around the world, but there are also inventions that, when you see them, you just want to exclaim: “How did they think of that?” .
We bring to your attention an overview of the most strange devices and unusual methods designed to protect your property.
UK: spray that marks burglars
An unusual spray mixed with synthetic DNA molecules was invented in the UK by two brothers, one of whom works in the police, and the other is a chemist.
A special device, which is mounted at the front door, sprays spray on burglars as soon as they cross the threshold of a guarded apartment.
The spray is visible only in ultraviolet rays and cannot be wiped off with conventional means, which allows the police to prove the guilt of the attackers.
Law enforcement agencies in Foggy Albion are actively promoting the new security system and also advise using “DNA markers” to mark computers, phones, tablets and other valuables.
South Africa: fire, not a machine
Johannesburg lawyer Charles Fourier has invented one of the most original ways to combat car thieves.
Fourier’s invention is very simple in design and extremely effective during an armed attack: a liquefied gas cylinder is installed in the trunk of the car, which, by pressing a button, is supplied to the “nozzles” mounted under the front doors.
The gas is ignited by an electric spark — a column of flame over two meters long bursts out of the “nozzles”. The device was patented under the name Blaster and was a hit with the local population.
USA: a chip monitors the safety of towels
Every month, hotels around the world lose between 5% and 20% of the bathrobes, towels and sheets that guests grab as souvenirs.
To solve this burning problem in the hotel business, an American company has invented a microchip that allows you to monitor the location of linen.
According to the developer, chips that are not susceptible to washing successfully help combat theft. For example, a hotel in Honolulu managed to reduce the number of stolen towels from four thousand to 750 pieces and saved about $15,000 per month.
China: “keep and don’t let go!”
To combat thefts, Chinese police decided to take radical measures.
Every night, a team of 80 people scours the streets from midnight to 6 a.m., looking for cars that might be stolen.
Potential victims of car thieves have their tires deflated so that they cannot drive anywhere.
It’s tough, but effective: according to the local police chief, flat tires help prevent car thefts, and local residents are finally starting to park their cars in secure parking lots.
Israel: dew is a guard
A group of scientists from Tel Aviv University have invented a security device that is almost invisible to the human eye, but has “eyes, ears and a nose.”
The new device is called “Smart Dew”. Each drop of “dew” is a sensor the size of a water drop, which can create a small security zone around itself, and several such drops can cover a huge area.
Using a built-in magnetic sensor, the “drop” can detect an intruder by heat signature, exhaled carbon dioxide, sound or vibration, and if the intruder is traveling in a vehicle, then by changes in ambient light.
The number of sensors connected in such a “smart network” can reach several thousand.
Japan: wasabi will warn of fire
The 2011 Ig Nobel Prize went to Japanese scientists who invented wasabi-scented fire alarms.
Researchers have found that Japanese seasoning contains components that are strong irritants for the nose.
If wasabi enters the air, a person will wake up, which means he will be able to notice the danger in time and escape in the event of a fire.
Australia: thunder and lightning against hijackers
The inventions of the brilliant Nikola Tesla were adopted by his ardent fan and follower from Australia.
He came up with an alarm that would scare any thief: few would dare to approach a car surrounded by small lightning bolts.
Tesla alarm is designed only for a psychological effect: it only looks scary, but in fact it is absolutely safe for humans.
Russia: silent channel
The Russian company Arkan has developed a security system that uses a unique technology for transmitting data over a secure radio channel.
If a similar system is installed in a house or car, then in the event of an intrusion or attempted theft, an alarm signal is transmitted via a radio channel that is resistant to any means of signal suppression and works reliably under any conditions.
Whatever technical means the attackers use, be it a regular jammer or a powerful radio jamming device, an alarm signal is guaranteed to be sent to the monitoring center.
Owners of a system with a non-jamming radio channel can be sure that they will receive immediate assistance and their property will remain safe and sound.
The data transmission technology patented by the Arkan company has been awarded national awards in the field of science and technology.
