Wireless home automation systems have several advantages, especially in terms of convenience and savings, because most of our equipment is easy to install, and usually does not require restrictive electrical modifications or intervention by electricians. However, this installation is not without risks. In fact, anti-theft devices with jammers can enter your house without installation. Ziblue’s Christophe will describe the correct measures to avoid this kind of rogue invasion as much as possible.
1- What is interference?
First, I want to remind you that jammers are prohibited in France and most European countries. However, obtaining it on the Internet does not seem to be complicated (200-300 euros). Interference is the dissemination of information clouds that prevents communication between elements. The message is sent by the sensor, but it cannot be heard from the center console. Imagine two people chatting in a bar and the football team singing to celebrate their victory. The two will face each other forever, but they will no longer be able to get along.
2-Why do anti-theft use jammers?
Jammers paralyze a large number of radio alarms and connected objects. The same jammer has been used to steal cars. 70% of car thefts are carried out using portable jammer and other electronic cards. Radio alarm paralysis allows thieves to enter houses, shops or other locations without reporting their presence.
3- How many thefts are made using this method each year?
Using these jammers to estimate theft is very difficult, because by definition they cannot be traced. However, the Ministry of the Interior pointed out that 50% of the incursions occurred without intrusions and intrusions (including many options). Or about 280,000 in 2016.
4- Can we avoid paper jams?
No, but we can prevent it. The RFPlayer on the 433 and 868 MHz frequencies informs you that interference has started or is happening, and it is likely that malicious behavior will soon occur in your home, business, etc.
5- If I have an anti-jamming system, is there no risk of failure?
From a marketing point of view, there are several claims that your wireless alarm or home automation system can protect you from interference. The most common are:
Dual frequency communication: Does not work, because most jammers we see on the website cover both frequencies.
Detect GSM and 4G interference: This type of interference will prevent communication with outdoor platforms, but if the center console does not receive a message indoors, the sensors will not be sent, which means they will never work.
6- How to warn you of malfunction?
RFPlayer and its Jam’Alert function can be connected to the most important home automation solutions on the market, such as Eedomus, Jeedom or Vera. The scenes of these boxes can be sent by email, SMS or wired alarm after receiving the information. If you don’t have a home automation device, there is also an Android Jam’Alert app (Google Play) that can connect to a small TV box (Android) or tablet and automatically send SMS notifications of interference detection.
7- If my device can communicate wirelessly and cannot be used due to this interference, what kind of alert will I receive?
As mentioned earlier, the Jam’Alert application on Android is SMS. If connected to a home automation device, it depends on the services it provides (SMS, email, etc.). The idea is to avoid theft. In addition to the warning message, the best solution is to trigger a small siren to make the thief think that using the jammer does not work.
8- If you know that GSM also uses wireless communication, how can you receive the alert SMS?
GSM interference will not affect Jam’Alert’s text messages or emails, because the home automation box or Android TV box communicates directly with the telecommunications box via Ethernet.
9- In addition to SMS, various methods of notification are recommended.
Not necessarily because SMS will immediately notify you of the opposite email, which can be kept in the spam box or drowned in all your emails.
10- Despite these warnings, how can you stop this thief from stealing our property?
Small wired alarms seem to be the easiest for us, but you can also contact security personnel or neighbors. If your house is encrypted by a jammer, you will not be able to close the blinds and turn on the lights, and all the simulation scenes on the scene will be unavailable. Must have external information.
