Unveiling False Security Screens in Movies

The recent release of "eavesdropper 2" was fueled by the use of security equipment, and the appearance of security devices in movies has become a common occurrence. The plot is able to interlock and climax repeatedly. However, not all security shots are real, and I will expose the false security shots that were once presented in the movie for you.

Camera 1: A glass filled with red wine can detect infrared radiation

Answer: No!

All substances above absolute zero (-273.15 ℃) can produce infrared radiation. Modern physics refers to it as the field of thermal radiation anti-theft alarm, for the reason of knowing. Infrared detectors are widely used, and their biggest feature is their strong concealment, which cannot be seen by the naked eye. Even when viewed through a red wine glass, infrared rays cannot be seen.

Camera 2: Hiding in front of the reflective film and entering the infrared detector area

Camera 2: Hiding in front of the reflective film and entering the infrared detector area

After special night vision goggles, red wine. In some movies, directors come up with another trick to evade the infrared detector's alarm, which is to hide in the reflective film. Using a reflective film to reflect infrared radiation back, so that the receiving device can receive the infrared radiation without triggering an alarm. This scene appeared in the Hong Kong movie "The Queen's Secret Order".

Answer: No

In this scenario, the reason is in the movie. Infrared radiation devices are commonly used for security purposes. Infrared radiation is usually paired in pairs, with one end being the emitter and the other end being the receiver. When an object enters the infrared region and blocks or partially blocks infrared radiation, an alarm occurs. So, even if a reflective film is used, it can really bounce back the radiation emitted by the detector in the original path, but only reflect the radiation from the transmitting end back to the transmitting end. The receiving end still cannot receive the infrared radiation, and in this case, an alarm still occurs.

Camera 3: Using a dead person's iris to pass through the access control system

Some members of terrorist organizations are using iris recognition access control systems in the United States. I always like to cruelly use the eyes of the deceased for iris comparison in order to pass through the access control.

Answer: No

It has now become a biometric instrument used in many high-tech venues and customs clearance ports. It is also a commonly used biometric prop in movies. Due to the uniqueness of the iris, the development of iris recognition can be traced back to the 1880s. It is not easily affected by external factors, so the usage rate of iris is relatively high in some places with high security levels. But when the human brain dies or the eyes leave the body, the iris tissue completely contracts, resulting in dilated pupils, that is, the iris undergoes changes. In this case, using an ex vivo iris cannot be recognized

Lens 4: The miniature camera can transmit several hundred meters

Lens 4: The miniature camera can transmit several hundred meters

A professional thief bought a miniature camera on the streets of Chongqing in 'Crazy Stone'. Install it in the exhibition hall. Monitor the exhibition hall from a few hundred meters away in the car.

Answer: No

The micro cameras that appear in the movie are equipped with built-in transmission modules, and the reason is that micro cameras are generally divided into built-in and external configurations. According to the needs of the movie. As far as the author knows, cameras with built-in transmission modules generally have a power of 10 milliwatts and a transmission distance of 5060 meters in open areas. Through the lens of the movie, the terrain of the exhibition hall is complex and separated by multiple walls. In such an environment, professional thieves who are far away on the street cannot see the situation inside the museum at all

Lens 5: Infrared flush toilet replaces infrared alarm

Due to limited funds, it is still in Crazy Stone. The security team leader removed the infrared sensor from the flushing toilet and turned it into an infrared alarm.

Answer: No

The principle of active infrared alarm is temperature detection, although both use the principle of infrared sensing. The flushing toilet, on the other hand, is waterproof due to the change in charge caused by external induction of infrared radiation, with a significant difference in sensitivity and a smaller coverage area compared to an alarm. Due to its application range, infrared flush toilets have a much shorter sensing distance compared to infrared alarms. Moreover, since they are already set at the factory, modifying them can be problematic as objects often need to be placed very close to respond.
