Let us be clear from the beginning: in most thefts, alarm phone jammers are relatively rare. There are many reasons for this. According to INHESJ's research, 33% of the thefts are minors. Of the remaining 67%, it is adults who steal in garages, sheds, second homes, houses or apartments, and in the vast majority of cases, it is not “great professionals” who cheated on this system, but criminal. Almost not suppressed... It is said that the opportunity makes the thief a thief. It seems that the situation in theft cases is still the same (the clarification rate is only close to 15%), and sometimes the punishment is too bad.
In France, the possession and sale of alarm cell phone jammer is prohibited. According to Article L39-1 of the "Post and Telecommunications Act", those who possess this system will be sentenced to 6 months in prison and a fine of 30,000 euros.
Only having an alarm phone jammer will be very suspicious, and many criminals will not take risks
Nowadays, anti-theft personnel no longer wear gloves and no longer wear screwdrivers in order to be able to deny the whole fact when arrested. Instead, they used tools found in the garden and socks belonging to the victim. The fact of wearing gloves can still be explained in winter, but there is no fact of human interference. Therefore, for those thieves who will no longer be able to adopt his classic line of defense "I did nothing, I was there by accident", wearing a cell phone jammer will be very "sensitive". The suspicion will be lower and the possibility of conviction will be greater.
- Alarm jammers usually have a relatively low price range (between 5 and 50m) and higher prices (average between 90 and 500 euros).
- Yes, although the prohibition order is easy to spot. In a big house, all the detectors cannot be jammed at the same time, and the anti-theft device runs the risk of triggering the siren, being stopped or being surprised.
- Mobile phone jammers will disrupt the transmission to a certain distance in several "frequency bands".
- For example, a mobile phone jammer can block GSM waves between 900 and 980 MHz, GPS waves between 1570 and 1580 MHz, and WIFI waves between 2400 and 2500 MHz.
Therefore, the frequency band is stopped every time. The cell phone jammer can be portable, close to a pack of cigarettes in size. Therefore they are not very powerful and have a low range. Instead, they can be larger (approximately 15 * 15 cm) and can run on a power source. In this way, the range is even larger, up to 80m. These can cut off multiple frequencies at the same time, thereby cutting off the connection between various alarm components and GSM communications.
The use of alarm cell phone jammers in burglary cases is relatively rare, largely due to legal restrictions and the effectiveness of other security measures. In France, the possession and sale of these devices is strictly prohibited under Article L39-1 of the Postal and Telecommunications Code, punishable by up to 6 months in prison and a €30,000 fine. Criminals are increasingly wary of possessing such devices, as their mere possession can arouse suspicion and increase the likelihood of a conviction.
Despite legal deterrents, some people may still be tempted to use cell phone jammers to block alarm systems. These devices typically operate by jamming transmission frequencies within a specific band, such as GSM, GPS, and WIFI waves. While portable jammers are small and have a limited range, larger models powered by an external power source can cover a wider area, up to 80 meters. By blocking communications between alarm components and the GSM network, these jammers can disable security systems, creating opportunities for theft.
The effectiveness of cell phone jammers to bypass alarm systems is not guaranteed
In larger properties, jamming all detectors simultaneously can be challenging, increasing the risk of triggering an alarm or encountering unexpected obstacles. Additionally, advances in security technology have resulted in more sophisticated alarm systems that are resistant to jamming attempts.
- The prevalence of burglaries committed by minors and opportunistic criminals suggests that most thefts do not involve elaborate plans or the use of high-tech devices such as cell phone jammers.
- Instead, thefts often occur in homes, garages, or second properties, with criminals exploiting gaps in security measures or taking advantage of unattended premises.
- While cell phone jammers can be a potential threat to security systems, their illegal status, limited effectiveness, and availability of alternative security measures make them a relatively uncommon tool in the professional thief's arsenal.
- As law enforcement agencies continue to enforce regulations and homeowners invest in robust security solutions, the risk of using cell phone jammers as a means of circumventing alarm systems remains relatively low.
