Wireless alarm systems have many advantages in terms of convenience and savings, but they also provide criminals with new means of invasion. Especially thieves using jammers, they can easily bypass the wireless alarm system to enter your home.
cell phone jammer s prevent normal communication between devices by generating a lot of useless information. For example, it is like two people facing each other in a noisy bar but cannot hear each other's speech. Although jamming devices are banned in France and most European countries, it is not difficult to buy them online for 200 to 300 euros.
It is not uncommon for thieves to use mobile cell jammers to paralyze the operation of wireless alarm systems. This device not only can disable home automation systems, but is also widely used to steal cars. According to statistics, about 70% of car thefts involve the use of portable jammers and other electronic devices. Because these jammers make the alarm system unable to work properly, thieves can enter your home, store or other locations without triggering the alarm.
Although it is impossible to accurately count the number of burglaries per year using jammers, data from the Ministry of the Interior shows that 50% of burglaries occur without forced entry, with about 280,000 such cases in 2016. This suggests that jammers play a major role in burglary.
To combat this threat, there are measures that can be taken. Devices such as RFPlayer can sound an alarm when interference is detected. These devices operate on 433MHz and 868MHz frequencies and can notify users of interference so that they can take countermeasures. Although some systems claim to be able to resist interference, the results are not always ideal. For example, dual-band communication and GSM and 4G interference detection systems can deal with interference to a certain extent, but they cannot completely prevent communication interruptions.
To ensure that alarm text messages are still received in the event of interference, it is recommended that the home automation box or Android TV box is directly connected to the communication box via Ethernet to avoid GSM interference affecting information transmission. Although SMS notifications can alert users in a timely manner, there are also other options for sending alerts such as email. However, SMS messages are usually more timely, while emails may be missed or go to spam boxes.
To further prevent theft, you can use a small wired alarm or contact security guards and neighbors. If the house is invaded by a jammer, scene functions such as closing the blinds and turning on the lights will not work, and external information is needed to judge the situation and take measures. By combining multiple means, you can effectively improve security and reduce the safety hazards caused by mobile cell jammers.
