Frequency inhibitors, how do they work?

The use of frequency inhibitors is increasingly widespread in thefts of vehicles and houses. In the last decade, the use of systems to inhibit the alarm signal has exploded in a directly promotional way to the number of robberies in Spain. In fact, the Generalitat de Catalunya itself was forced to publish a video in 2018 showing the operation of this type of apparatus through an intervention by the Mossos d’Esquadra. Today the systems are much more advanced and complex, as we will see below. And security is not an option, but a necessity.

How do frequency inhibitors work in robberies?

Frequency inhibitors, also known as signal jammers or inhibitors, are defined as devices whose sole purpose is to block the signal of a certain environment through the emission of an “oversized” signal. The operation of this type of apparatus is very simple.

Broadly speaking, the electronic schematic followed by the disturbers consists of a signal generator and a transmitter. The first component is in charge of generate the signal on the same frequency that the devices you want to veto operate (mobiles, GPS, alarms …), while the second component is in charge of expanding the signal in its environment to block the “channels” through which the rest of the devices operate.

This is what a frequency inhibitor looks like.

Depending on the size of the disturber, the device can block areas of several square meters, such as entire homes and even housing estates. Ironically, the use of these devices was originally intended to protect some government areas. This is why the sale and use of disruptors is prohibited in Europe as of today. In fact, its use in Spain is punishable by fines ranging from 500,000 euros to 20 million. Yes, you read it right. 20 million euros.

Unfortunately, getting a signal inhibitor is as easy as surfing the web for a couple of minutes. The investment is minimal, so anyone can access a disruptor if they have the necessary means. A fact: at least 600 people are interested each month in Spain by signal inhibitors and similar devices on the Internet, according to Ahref. Nor is it by chance that they have registered more than 14,000 robberies in the first three months of 2020, according to data from Europa Press.

Is there any workaround to override frequency inhibitors at home?

The truth is that yes. Companies like Prosegur have designed a whole system of alarms based on devices with triple security. This type of system duplicates communication channels to ensure connections with the company’s switchboards, which they remain active 24 hours a day, 365 days a year. In this case, one of the routes is directly connected to the electric current, while the second route establishes a connection through the Internet. In this way, the system is protected against power outages, equipment sabotage and, ultimately, frequency inhibitors.

Together with a support system with perimeter detectors, security fences and surveillance cameras, the perimeter becomes practically impassable. The Prosegur alarm system has a response of less than 29 seconds with immediate notice to the Police and own guards service in case of need. To this we must add that all triple security alarms have a movement and temperature sensor, with automatic activation in the event of detecting movements in the protected areas of the home or the environment.
