Night vision goggle (NVG) legislation in France: what the law actually says

The 30-second version. In France, a night vision goggle is not banned in principle, and its classification does not depend on its generation (Gen 2, Gen 3…). What matters legally is its intended purpose and its use configuration. An NVG held in the hand, that is neither a weapon sight nor designed exclusively for military use, falls under free sale. Conversely, as soon as a device is used "hands-free" (helmet- or head-harness-mounted) or used as a weapon sight, it shifts into category A2 (war materiel), whose acquisition and possession are in principle reserved for the State and authorised bodies.

Legality is, by far, the first question night vision buyers in France ask themselves — and it is also the area where the most approximations circulate. This page sets the record straight, with the text of the law in hand, without shortcuts or false reassurance.

1. The general framework: the four categories of weapons and materiel

Since the reform that came into force in 2013, French law divides weapons, ammunition and war materiel into four categories, defined in article L311-2 of the Internal Security Code (CSI):

Category A is subdivided into A1 (weapons) and A2, the latter covering "weapons classed as war materiel, materiel intended to carry or operate firearms in combat". It is within category A2 that the classification of night vision is decided.

2. Where does night vision fall? Heading A2, 14°

The detail of the materiel classified under A2 appears in article R311-2 of the CSI. Point 14° specifically targets night vision. Here is the official text, word for word (the official version of French law is in French):

« 14° Matériels d'observation ou de prise de vues conçus pour l'usage militaire ; matériels de visée ou de vision nocturne ou par conditions de visibilité réduite utilisant l'intensification de lumière ou l'infrarouge passif destinés exclusivement à l'usage militaire et matériels utilisant les mêmes technologies qui peuvent être mis en œuvre sans l'aide des mains. »

Unofficial English gloss (for guidance only — the French text above is the sole official version): "14° Observation or image-capture equipment designed for military use; sighting equipment, or night-vision equipment or equipment for reduced-visibility conditions, using light intensification or passive infrared, intended exclusively for military use, and equipment using the same technologies that can be operated without the use of the hands."

This text, dense in appearance, in fact sets out three classification criteria for A2. A night vision device shifts into war materiel if it meets at least one of the following:

1. Military purpose: it is designed or intended exclusively for military use;
2. The sighting function: it is a weapon sight (intended to be mounted on a firearm for aiming);
3. The "hands-free" capability: it can be operated without the use of the hands — typically helmet- or head-harness-mounted.

Conversely, a device that ticks none of these boxes — for example a handheld observation monocular or binocular, not intended for military use and not designed as a sight — does not fall under heading A2-14° and is subject to free sale in France.

3. The distinction that changes everything: possession ≠ use

This is the most misunderstood point, and the one where most sites fail to educate. Two things must be separated:

• Possession and sale of an observation NVG (non-sight, non-military) are free. You may buy and own it without authorisation or declaration.
• Use, on the other hand, can tip the device into the scope of category A2. Concretely, using an NVG "hands-free" (helmet-mounted) corresponds precisely to the third criterion of heading 14°.

In other words: it is not the object itself that is prohibited, it is a way of using it that brings it under the war-materiel regime.

4. The decisive criterion — and its grey area: "hands-free"

The heart of the matter lies in the phrase "that can be operated without the use of the hands." Three readings coexist, and one must be honest about their limits:

What is clear. A device actually used helmet-mounted (both hands free) falls under the hands-free criterion of heading A2-14°. This use is, in practice, reserved for the armed forces, law enforcement and authorised bodies.

What is accepted in practice. The possession and sale of "consumer" and "pro" monoculars and binoculars remain free in France, even though a large share of them have an interface (rail, J-arm, dovetail) that allows helmet mounting. The dominant practical reading therefore distinguishes possession of the object (free) from hands-free use (restricted).

What remains a grey area. The text targets materiel "that can be operated without the use of the hands" — a capability, not merely an established use. A strict reading could attach to A2 a device sold ready for helmet mounting. To date, this strict interpretation is not the one that prevails on the civilian market, but it is not legally excluded. If in doubt about your configuration, request a written position from the administration.

Bottom line. The line is not "Gen 2 vs Gen 3," nor "civilian vs military" in the brand sense. The line is: weapon sight? intended for military use? operated hands-free? If the answer is no to all three, you are within the scope of free sale.

5. Myth #1: "It's the tube generation that determines legality"

False. This is probably the most widespread confusion. The current regime (categories A/B/C/D) does not classify by generation (Gen 1, Gen 2+, Gen 3) or by tube brand (Photonis, NNVT, L3Harris…). This idea comes from the old regime (pre-2013), which distinguished materiel by a resolution threshold. This technical resolution criterion no longer appears in the current heading A2-14°.

Today, a Gen 3 tube in a handheld monocular remains freely sold, while a Gen 2+ mounted on a helmet falls under the hands-free criterion. What matters is not tube performance, but the use and intended purpose of the complete device.

6. Myth #2: "Thermal is the same thing"

To be nuanced. Heading A2-14° targets light intensification and passive infrared (which encompasses certain thermal technologies) when they are designed for military use or operated hands-free. A handheld civilian observation thermal camera broadly follows the same logic as light intensification: it is military purpose and the hands-free configuration that tip it into A2. Technical characteristics (thermal resolution, NETD) have historically played a role; here too, check the classification of the specific model.

7. A special case: hunting

Be careful not to confuse two distinct regimes. Even when an NVG is of free possession under the Internal Security Code, its use for hunting falls under a separate set of rules (the Environment Code and hunting orders). The use of night vision devices and night-shooting aids for hunting is strictly regulated, even prohibited for most species and situations, outside specific prefectoral exemptions (e.g. certain culling operations). Free possession of an NVG therefore does not authorise using it to hunt at night.

8. What about professionals? The authorisation regime

For legitimate uses falling under A2 (security, public-service missions, aeronautics…), a door exists. Decree no. 2017-909 of 9 May 2017 amended article R312-27 of the CSI to allow an authorisation to acquire and possess materiel falling under headings 14° and 17° of category A2 to be granted to private bodies and companies carrying out a public-service or public-security mission, under conditions set by order. It is via this route, for example, that the question of equipping rescue helicopters with NVGs was handled. This authorisation remains regulated and granted on a case-by-case basis by the administration.

9. What are the penalties for a breach?

Acquiring, transferring or possessing category A materiel without the required authorisation is a criminal offence (délit), punished by the criminal provisions of the Internal Security Code (articles L317-4 et seq.). The penalties incurred include a prison sentence of several years and a substantial fine, increased in the event of aggravating circumstances (organised gang, stockpiling). Given the evolution of the texts, check the exact amount applicable with an up-to-date official source. The essential message: unauthorised hands-free use is not a mere administrative infraction, it is a criminal offence.

10. In practice: buying an NVG fully legally in France

To stay within the scope of free sale, keep three reflexes in mind:

1. Favour handheld use (observation monocular or binocular); it is the clearest configuration legally.
2. Do not use your device as a weapon sight: the sighting function tips it into A2.
3. Be aware of the "hands-free" threshold: mounting your device on a helmet corresponds to the criterion that falls under the war-materiel regime.

Our LNVM (monocular) and LAB-NVS (binocular) devices are observation materiel: designed for night observation and perception, they fall under the free-sale regime when used handheld and outside military or sighting use. We detail their design and their NNVT tubes with full transparency, because an informed purchase starts with honest information — including about the legal framework.
