And if the room doesn\u2019t fill up, the burglar will simply carry on. Choosing the right model does not depend on a budget or a brand; it depends above all on a single criterion: the area to be protected.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The short answer: each model in the Density\u00ae range covers a specific area, ranging from 40 m\u00b2 for the Density Air up to several thousand m\u00b2 for the HP14000 IP. But square metres aren\u2019t the only factor. Ceiling height, risk level and the type of premises also come into play.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide provides you with everything you need to choose the Density fog generator that\u2019s right for your situation, without over- or under-specifying your protection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why floor space is the number one selection criterion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A fog generator works by filling the space with a thick, opaque white fog. The aim is simple: to reduce visibility to zero before the intruder has had time to locate anything. To achieve this, the generator must produce enough cubic metres of fog to completely fill the room in a matter of seconds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the power output is insufficient for the volume of the room, the fog dissipates before reaching the corners. The intruder retains a zone of visibility and can continue to act. This is precisely where many less effective systems fail: they produce a low-density fog that never completely fills the space.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Density fog is twice as dense and three times faster than the average fog system available on the market. This performance is the result of a patented turbo pump and a specially formulated liquid. But even with this technical superiority, a Density Air will never replace a Density 900 in an 80 m\u00b2 room.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In short: the floor area determines the minimum power required. Below the saturation threshold, the system loses all its deterrent effect. Choosing a model with a slightly higher power rating than your actual floor area is always the right decision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Buying guide: which Density model is best for which floor area?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here is the complete cross-reference table for Density\u00ae models and the surfaces to be protected. This information is taken from the official technical data sheets.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Model<\/strong><\/td><td><strong>Covered area<\/strong><\/td><td><strong>Fog generation<\/strong><\/td><td><strong>Maximum ceiling height<\/strong><\/td><td><strong>Typical use<\/strong><\/td><\/tr><tr><td>Density Air<\/td><td>Up to 40 m\u00b2<\/td><td>400 m\u00b3 in 45 s<\/td><td>2.3 m<\/td><td>Households, small businesses<\/td><\/tr><tr><td>Density 390<\/td><td>5 to 40 m\u00b2 of floor space<\/td><td>390 m\u00b3 in 20 s<\/td><td>2,5 m<\/td><td>Tobacco shops, small shops, ATMs, safes<\/td><\/tr><tr><td>Density 900<\/td><td>5 to 100 m\u00b2 of floor space<\/td><td>900 m\u00b3 in 29 sec<\/td><td>3 m<\/td><td>Tobacco counters, secure storage rooms, high-value premises<\/td><\/tr><tr><td>Density 1500 IP<\/td><td>80 to 200 m\u00b2 of floor space<\/td><td>1,500 m\u00b3 in 44 seconds<\/td><td>4 m<\/td><td>Opticians, motorbikes, bicycles, medium-sized shops<\/td><\/tr><tr><td>Density 2400 IP<\/td><td>150 to 300 m\u00b2 of floor space<\/td><td>2,400 m\u00b3 in 80 seconds<\/td><td>5 to 6 m<\/td><td>Large retail outlets, small warehouses<\/td><\/tr><tr><td>Density HP6000 IP<\/td><td>Several hundred m\u00b2 of floor space<\/td><td>6,000 m\u00b3 in 80 seconds<\/td><td>6 to 8 m<\/td><td>Large warehouses, logistics hubs<\/td><\/tr><tr><td>Density HP14000 IP<\/td><td>Several thousand m\u00b2 of floor space<\/td><td>14,000 m\u00b3 in 200 seconds<\/td><td>6 to 12 m<\/td><td>Extra-large warehouses, industrial storage<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Density Air: protection for compact spaces (up to 40 m\u00b2)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Le<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/density-air\/\">\u00a0Density Air<\/a>\u00a0is the entry-level model in the Density\u00ae range. It is primarily aimed at private individuals and small businesses with a moderate risk profile. Its key feature is a compact design available in seven different front panels (including decorative models), allowing it to blend discreetly into any interior without detracting from the d\u00e9cor. It produces 400 m\u00b3 of fog in 45 seconds, which is sufficient to completely saturate a 40 m\u00b2 room with a standard ceiling height.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In practice, this model is ideal for a living room, a studio flat, an office or a small local shop. For rooms with higher ceilings or premises with a higher risk level, you will need to opt for the next model up.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Density 390: the standard for small shops and tobacconists (5 to 40 m\u00b2)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Le<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/density-390\/\">\u00a0Density 390<\/a>\u00a0covers the same area as the Density Air, but with a more robust technical specification: a ceiling height increased to 2.5 m, a multi-directional nozzle, and, above all, EN50131-8:2019 and NF&amp;A2P version 2019 cyber certification, the two leading standards in the active protection market.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is the model recommended for<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/tobacco\/\">\u00a0tobacco shops<\/a>, small shops, ATM areas or secure storage facilities. It produces 390 m\u00b3 in just 20 seconds, making it one of the fastest machines in its class within the range.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In summary: the Density 390 is the obvious choice for tobacconists and small businesses requiring full certification. Its 20-second response time makes it particularly well-suited to dealing with sudden intrusions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Density 900: up to 100 m\u00b2 with a ceiling height of 3 m<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As soon as the floor area exceeds 40 m\u00b2 or the ceiling height approaches 3 metres, the<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/density-900\/\">\u00a0Density 900<\/a>\u00a0stands out. It produces 900 m\u00b3 of fog in 29 seconds \u2013 more than double that of the 390 model \u2013 whilst offering comparable responsiveness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This model is particularly well suited to tobacco displays (the main sales area), safe rooms, and<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/pharmacies\/\">\u00a0pharmacies<\/a>, self-service banking facilities and all premises containing high-value goods up to 100 m\u00b2. It is also certified to EN 50131-8:2019 and NF&amp;A2P.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do you provide security for a shop measuring between 40 and 100 square metres?<a href=\"https:\/\/www.densityfrance.fr\/en\/request-a-free-quote\/\"> Contact the Density network of installers for a personalised quote.<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Density 1500 IP and 2400 IP: for medium-sized retail premises (80 to 300 m\u00b2)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For properties ranging from 80 m\u00b2 to 300 m\u00b2, two models are available. The<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/density-1500\/\">\u00a0Density 1500 IP<\/a>\u00a0(80\u2013200 m\u00b2, height 4 m) is aimed at<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/opticiens-solaire\/\">\u00a0opticians<\/a>, the<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/bike-shops\/\">\u00a0motorcycle and bicycle shops<\/a>, and medium-sized retail outlets. The<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/density-2400\/\">\u00a0Density 2400 IP<\/a>\u00a0(150\u2013300 m\u00b2, height 5\u20136 m) is designed for large retail chains, shopping centres and small warehouses with high ceilings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Both models feature a native high-security IP board with a built-in Wi-Fi antenna, enabling remote control via the Density cloud. In practice, this means that a security operator can test, monitor and activate the system without having to travel to the site.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Density HP6000 IP and HP14000 IP: the world\u2019s most powerful warehouse solutions<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The HP range offers a level of performance unrivalled on the market. The HP6000 IP covers several hundred square metres with ceiling heights of 6 to 8 metres, the<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/density-hp14000\/\">\u00a0HP14000 IP<\/a>\u00a0can cover several thousand square metres under ceilings up to 12 metres high, producing 14,000 cubic metres of fog in 200 seconds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These models have been designed for<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/warehouses-and-storage-buildings\/\">\u00a0logistics warehouses<\/a>, storage platforms and industrial sites that have hitherto been unable to benefit from effective active protection. A single HP14000 IP replaces the equivalent of six 2400 IP generators, whilst consuming significantly less power than the combined total of those units.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In summary: HP models do not comply with any existing standards (no standard covers these power levels), but they are the only ones capable of saturating such large volumes within an operational timeframe.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Intruder-repellent fog vs smoke: the differences that make all the difference<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Intruder-repellent fog vs smoke: the differences that make all the difference<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A smoke canister is a single-use pyrotechnic device. One cartridge, one shot, and that\u2019s it. If the intruder triggers your alarm again or if the system goes off again, nothing happens. You also need to change the cartridge every time the alarm is triggered. And, crucially, smoke grenades leave residue and deposits on surfaces, fabrics and items in the room.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Density fog system operates on a radically different principle. The cartridge is liquid-based, multi-shot, and has a shelf life of three years. Depending on the programmed firing time (adjustable to the second), each cartridge allows for between 3 and 12 activations. The mist produced is non-toxic, certified for use in food environments (FCMs certification, unique in the sector), and leaves no residue or marks on furniture, walls or clothing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In terms of density, Density fog is twice as dense and three times faster than conventional smoke bombs. This isn\u2019t just a marketing claim: it\u2019s the direct result of a patented turbo pump and an optimised liquid formula.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In short: smoke grenades and fog are in a different league. Smoke grenades are cheaper to buy, but they are single-use, polluting and significantly less effective. Density fog is multi-shot, non-toxic, denser and certified. When it comes to professional protection, the comparison ends there.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Other factors to consider in addition to floor area<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Floor space is the starting point, but it isn\u2019t the only factor to consider. Here are four additional factors to bear in mind before choosing your model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ceiling height. A room measuring 80 m\u00b2 with a ceiling height of 4 metres has a volume of 320 m\u00b3. The same room with a ceiling height of 2.5 metres has a volume of 200 m\u00b3. The same unit will not be suitable. Each Density model specifies the maximum ceiling height to ensure full saturation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The level of risk and the required certifications. Insurers and certification bodies sometimes require specific standards. The Density\u00ae range (excluding Air and HP models) is certified to EN50131-8:2019 and NF&amp;A2P version 2019 cyber. The latter certification includes protection against cyber attacks, a requirement that is increasingly common in professional tenders.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The presence of foodstuffs. If your premises store or handle food products (<a href=\"https:\/\/www.densityfrance.fr\/en\/our-solutions\/bakeries\/\">bakery<\/a>, (e.g. restaurants, food warehouses), Density is the only fog generator on the market to hold FCMs certification, authorising its use in food environments. This is a deal-breaker compared to other systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Connectivity and remote control. From the Density 1500 IP onwards, the high-security IP card is built-in and comes with a Wi-Fi antenna. It provides access to the Density cloud for remote monitoring and testing of the system, without the need for physical intervention. For networked premises or remote monitoring operators managing multiple sites, this is a decisive operational advantage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.densityfrance.fr\/en\/how-an-anti-intrusion-fog-generator-works\/\">How does an anti-intrusion fog generator work?<\/a>\u00a0\u2014<a href=\"https:\/\/www.densityfrance.fr\/en\/our-assets\/certifications-and-guarantees\/\">\u00a0Certifications and key features of the Density range<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How many generators are needed for a room with a complex layout?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A simple rectangular room is easy to size. But an L-shaped space, a shop with alcoves or a warehouse divided into compartments raises a different question: do you need one or more generators?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to feedback from installers in the Density network, spaces with extensive partitioning generally require one sound generator per separate zone. A single Density 1500 IP can provide sufficient coverage for an open-plan room of 150 m\u00b2. The same 150 m\u00b2 divided into three separate zones will likely require three Density 390 or 900 units, strategically positioned.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The multi-directional nozzle fitted to most certified models allows the mist to be directed to suit the layout of the room. The Density installer always carries out a site analysis before making any recommendations. This is important: incorrect positioning can compromise the system\u2019s effectiveness, even with a perfectly sized model.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When choosing a fog generator, the first step is to ensure that the output is correctly matched to the volume to be protected. The<a href=\"https:\/\/www.densityfrance.fr\/en\/fog-generators\/\">\u00a0Density\u00ae range<\/a>\u00a0offers seven models covering areas ranging from 40 m\u00b2 for the Density Air to several thousand m\u00b2 for the HP14000 IP, with a maximum ceiling height that must not be exceeded in each case.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Beyond floor area, ceiling height, the required certifications, the presence of foodstuffs and the level of connectivity are the four criteria that help narrow down the choice between two similar models. And if your premises have a complex layout, consulting an installer from the Density network remains the most reliable way to obtain a tailored recommendation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Contact INNOV S\u00c9CURIT\u00c9 for a free assessment of your premises and a bespoke quote: the right fog generator is one that is tailored to your specific space, not a one-size-fits-all model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.densityfrance.fr\/en\/request-a-free-quote\/\">Request a quote and contact us<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Un g\u00e9n\u00e9rateur de brouillard mal dimensionn\u00e9, c\u2019est une pi\u00e8ce qui ne se sature jamais compl\u00e8tement.
