That is what burglars themselves say, with one caveat. In a 2013 study by the University of North Carolina at Charlotte, based on a survey of 422 burglars held in prisons in the United States, 83% said they try to find out whether an alarm is present before acting, and 60% said they would pick another target if an alarm was present. Of those who discover an alarm during an attempt, half give up. The study relies on what the burglars said and was funded by an alarm industry foundation: it gives an order of magnitude, not a guarantee. An alarm complements a solid door and sensible precautions when you are away; it does not replace them.

Supra Sécurité offers on-site intervention within 48 hours in every Paris arrondissement and in the Hauts-de-Seine. A standard alarm installation takes 2 to 4 hours, depending on the layout.

No. Our alarm systems work with no mandatory subscription, and you own your equipment. Remote monitoring, by operators 24/7, is an option you can add; it is never compulsory.

For a flat in Paris, we recommend a wireless system with opening detectors on the doors and windows, one or two motion detectors and an indoor siren, all connected to your smartphone so that you can control it remotely. We size the system during the free survey.

Often, depending on your insurer: some offer a discount for an alarm installed by a professional. Conditions vary from one insurer to another, so check the terms of your policy before asking for a quote.

Not inside your own home: you are free to install an alarm there, whether you rent or own, especially a wireless one that needs no drilling. The approval of the co-owners is only needed if the installation affects the common parts or the façade, for example an outdoor siren. In that case, we give you the technical file to present to the managing agent.

7,072 residential burglaries were recorded in Paris in 2025, according to the French Ministry of the Interior (SSMSI), or 5.05 per 1,000 homes. That is 23.4% fewer than in 2024, but the level varies widely from one arrondissement to another: the 16th (6.05 per 1,000 homes) remains above the Paris average.

Three complementary steps: an alarm you can control remotely, so that you are alerted immediately; remote monitoring with alarm verification, so that an operator checks the alert and informs the police on your behalf; and Opération Tranquillité Vacances, a free police scheme in which patrols keep an eye on your home while you are away. You can sign up for it online or at your local police station.

All of Paris, from the 1st to the 20th arrondissement, with on-site intervention within 48 hours. Our base in Neuilly-sur-Seine puts us on the doorstep of western Paris, a few minutes from the 16th and the 17th.

It depends on the floor area and the number of entry points. For a two-bedroom flat (three main rooms), allow 2 to 3 motion detectors and 3 to 4 opening contacts. For a 150 m² house, allow 4 to 6 detectors and 5 to 8 contacts. Supra Sécurité carries out a free survey to size your system precisely.

Yes, with remote monitoring. The monitoring centre can contact the police when an alarm is confirmed. Its operators first verify the alert, by phone call or video check, before calling for an intervention, to avoid false alarms.
