Have surveillance cameras become obsolete when it comes to protecting our homes from burglaries? The thugs have in fact found a loophole, allowing them to completely circumvent the system and become, so to speak, invisible.
Install an alarm system, adopt a guard dog, post surveillance cameras, leave the television on, don’t close the shutters or ask a neighbor to come by regularly when you go on vacation… There are dozens of solutions to try to protect yourself against burglaries. And if the number of intrusions has decreased very slightly in recent years, the fact remains that 218,200 homes were burglarized in France in 2025 alone, according to the Ministry of the Interior.
It must be said that, unfortunately, criminals are also constantly developing new tricks to adapt: technological advances serve both parties, in a silent fight that never ends. Now, simple gadgets bought cheaply on the internet can allow them to thwart security systems without the slightest harm.
One of them, in particular, completely blurs the images from surveillance cameras… making burglars almost “invisible”. This object, which can be found in one click on many commercial sites (some for less than 20 euros), is a Wi-Fi jammer. A small device, no bigger than a telephone, which disrupts the signals emitted by surveillance cameras. All you have to do is approach it with the device, and instantly, the image becomes pixelated and the thief’s face becomes impossible to identify. For the moment, it is mainly in the United States that the phenomenon is noticeable. There, postmen have the habit of leaving packages in front of houses, which inevitably attracts thieves. The NBC News television channel also broadcast a video in which we see criminals using this technique to steal packages in front of a Texan house.
But of course, wifi jammers are not only used to steal Christmas gifts and other internet orders, they can also be used to jam cameras in order to break into the home. And like everything that comes to us from the States, it’s only a matter of time before French burglars get hold of the method. The only way to protect yourself is to opt for a surveillance camera that records on a memory card, and which therefore does not depend on Wi-Fi.
Furthermore, you should know that the use of a wave jammer has been prohibited in France for more than a decade: it is an offense, punishable by six months’ imprisonment and a fine of 30,000 euros. And this, in addition to the penalty incurred for burglary, which can amount to up to ten years of imprisonment and a fine of 150,000 euros.
