Definition and Risks of signal jammer Devices
Wireless home automation systems are popular for their convenience and cost-saving advantages. Most devices are easy to install and usually do not require the intervention of a professional electrician. However, this easy installation method also brings potential security risks. A thief with a jamming device can enter your home without a complicated installation process, rendering the anti-theft device ineffective.
A jammer device is a device that can hinder the transmission of information, making it impossible for elements to communicate normally. Although the use of jamming devices is banned in France and most European countries, it is not complicated to obtain them online (the price range is between 200-300 euros). The effect of interference is similar to that of two people chatting in a bar, and the surrounding noise makes it impossible for them to hear what each other is saying.
The effect of jamming devices on anti-theft devices
Jammers can paralyze many radio alarms and connected devices, rendering these anti-theft systems ineffective. For example, in many car thefts, thieves use portable jammer devices and other electronic devices to disrupt the car's anti-theft system. The same jammers can also be used in burglaries of homes, shops and other places, rendering the alarm system inoperable.
How common are blocking devices?
Although it is difficult to estimate how often they are used, according to the Ministry of the Interior, 50% of burglaries involve non-breaking into a home. In 2016, there were about 280,000 burglaries in France, many of which may have involved the use of jammer devices.
How to prevent interference?
Although interference cannot be completely avoided, there are some ways to reduce its effects. For example, RFPlayer devices can detect when interference has started or is in progress and notify the user of the potential threat. RFPlayer using frequencies of 433MHz and 868MHz can effectively prevent most interference.
Effectiveness of anti-interference systems
There is some effectiveness in wireless alarms or home automation systems that claim to prevent interference. Dual-band communication systems can reduce the impact of interference, but most jammers cover two frequencies and still affect the system. GSM and 4G interference detection systems can detect interference, but may still cause sensors to not transmit information properly.
Interference Alert Methods
RFPlayer and its Jam'Alert feature can be connected to major home automation solutions on the market, such as Eedomos, Jeedom and Vera. Through these devices, users can receive interference alerts via email, SMS or wired alarms. In addition, the Jam'Alert application for the Android platform can also send SMS notifications.
Alert Message Receive Methods
In the event of interference, users can receive alert messages through the home automation device or Android TV box Ethernet connection, ensuring that GSM interference will not affect the transmission of SMS or email. SMS is usually more timely than email, avoiding the risk of emails going into spam boxes.
Preventive Measures
In addition to receiving alert messages, there are some practical preventive measures that can be taken. Installing a wired alarm system is a simple and effective way to sound an alarm in the event of interference to scare off thieves. Users can also contact security personnel or neighbors to ensure that someone can respond quickly in an emergency.
