All the information on frequency jammers
A frequency jammer blocks an alarm’s signals, preventing it from communicating with its sensors or the control panel and rendering it inoperative. To prevent this, modern systems incorporate anti-jamming technology that detects tampering and maintains communication via alternative channels, ensuring security.
What is a frequency inhibitor?
Frequency jammers are electronic devices which, by generating very powerful interference, hinder or prevent an electronic device from transmitting a wireless signal.
They are used to block communication between devices, so when they are nearby, they ‘cut off’ all types of wireless signals, such as mobile phones, GPS devices, car keys, remote controls and, of course, security alarms.
Possession for personal use is prohibited, but they are actually very easy to buy, particularly from online shops, and they are very affordable.
Movistar Prosegur and Securitas Direct are the two best-known alarm companies in Spain; between them, they account for a large share of the market for residential customers and small businesses.
On this page, we’re going to take an in-depth look at the two companies and compare the features and specifications of the equipment they install, the services they offer, their prices, and their customers’ reviews.
Furthermore, to make this comparison more comprehensive and useful, we have included Spain’s third-largest security company, the American multinational ADT, in our analysis.
How does an anti-alarm frequency jammer work?
Frequency jammers work by emitting a ‘blank’ signal or electronic noise, which generates intense interference that prevents wireless signals from all other nearby devices from coming through clearly.
These devices are generally quite simple in operation and range in size from that of a mobile phone to a large suitcase. It all depends on the signal you wish to block or jam and the area you wish to interfere with. Frequency jammers are electronic devices which, by creating very powerful interference, hinder or eliminate the ability of an electronic device to transmit a wireless signal.

How can we protect ourselves against a frequency jammer?
Security companies are well aware of this problem and design anti-jamming alarm systems for homes and businesses. Some of the leading alarm companies, such as Prosegur and ADT, have highly effective anti-jamming systems, which work as follows:
1-On the one hand, the systems are fitted with a tamper detector, which detects when the alarm is being tampered with, sends a tamper signal to the monitoring centre and triggers an alarm.
2-Secondly, wherever possible, they connect the alarm control panel to the customer’s internet router via an RJ45 network cable, so that if the GPRS signal is cut off due to jamming, the system connects to the alarm monitoring centre via the network cable, which cannot be jammed, as jammers only affect wireless signals.
It is important to note that not all companies have this system in place, and whilst it is true that they all offer some form of jamming solution, this dual-channel network cable communication system is undoubtedly the most secure and reliable.
As an anecdote, we can recount cases of burglaries in industrial units where a frequency jammer was used, in which the alarm went off in the neighbouring unit – which was equipped with a jamming detector, unlike the one being burgled – and, thanks to the action taken by the neighbouring security firm, the police attended the scene and were able to prevent the burglary.
How to disable an alarm using a frequency jammer
Wireless alarm systems, which currently account for the majority of those installed, operate by connecting the various components to one another via radio, and in turn connect to the alarm control panel via GPRS (the same type of signal used by mobile phones to make or receive calls).
Wireless alarm systems therefore use two types of signal that can be jammed by a frequency jammer:
- The radio signal used to connect the components to one another.
- The GPRS signal they use to connect to the security company’s alarm monitoring centre.
