Some electronic gadgets have appeared on sale, which, with the “correct” setting, can interfere with the operation of traffic lights with all the ensuing consequences.
There are many products in the electronics market for legal or illegal useand one of them is zero flipper (Flipper Zero), which works with radio frequencies and can cause confusion in traffic. Its cost is about 300 euros.
Recently, a hacker bought this device to answer a question that is floating around the Internet: mCan this device change the traffic light from red to green? As you can see, the answer is yes.but it’s not at all what you think.
Flipper Zero has built-in RF receiverwhich allows him receive or transmit data on the same wireless frequencies as remote controls and other devices.
Most emergency traffic control devices do not transmit RF signals. Instead, they use infrared technology and communicate with receivers at traffic lights, writes carandmotor.gr. This the technology works by detecting a specific pattern of infrared light emitted by a transponder installed in a police car, fire engine or ambulance. When the receiver detects an infrared beam, the traffic control system changes the lighting mode to the emergency vehicle could safely pass through the busy intersection.
Illegal commercially available devices don’t work that way.. They generate pulses, and the built-in frequency generator can determine how fast the pulses are emitted. This allows devices to control an external set of infrared LEDs from an old CCTV camera to mimic an ambulance transmitter.
For reference: making and using one of these transmitters is not a good idea and illegal and you could end up in jail. And besides, in most modern traffic lights there is no way to hack the system with these “rough” devices.
