Night Vision and Thermal Imaging in Ireland: What Does the Law Say in 2026?

Possession, weapon mounting, night hunting — what the Firearms Act and the Wildlife Act actually allow in Ireland in 2026

Ireland occupies a distinctive position in Europe: owning a handheld night vision device or thermal camera is subject to no restriction whatsoever, but the moment a device is designed to be fitted to a firearm, it becomes a firearm in its own right under the law. This is a different legal architecture from most of its European neighbours, and enforcement has tightened noticeably since 2022–2023.

The Irish legal framework

Unlike France or Germany, Ireland has no single piece of legislation dedicated to night vision. The regime results from the combination of two bodies of law:

• The Firearms Act 1925, as amended by Section 26 of the Criminal Justice Act 2006, which redefines what constitutes a "firearm."
• The Wildlife Act 1976 (as amended), which governs the species, seasons, and methods permitted for hunting.

The core provision is Section 1(g)(i) of the amended Firearms Act 1925: any sight with a light beam, an electronic light-amplification device, or an infra-red device, designed to be fitted to a firearm, is itself classified as a firearm. Statutory Instrument 21/08 (as amended) confirms that such devices fall under the category of Restricted Firearms — the same category as a sound moderator (silencer).

Handheld possession and use: no restriction

For observation, security, unarmed sport use, hiking, or any application that doesn't involve mounting on a firearm, Irish law is among the most permissive in Europe:

• No licence is required to own or use a handheld thermal camera.
• No restriction applies to a night vision monocular or binocular that is handheld or helmet-mounted, as long as it is not designed to be fitted to a weapon.
• This covers most professional and recreational uses: private security, wildlife observation, boating, night hiking, and search and rescue.

It is this distinction — "designed to be fitted to a firearm" — that drives the legal outcome in Ireland, far more than the underlying technology (analog, digital, or thermal).

Weapon mounting: a Restricted Firearm Certificate is mandatory

The moment a night vision or thermal sight is intended to be fitted to a firearm, the process changes entirely:

• The buyer must obtain a Restricted Firearm Certificate from the Divisional Chief Superintendent of An Garda Síochána, via Form FCA1.
• An additional fee (around €80) applies to the granting of the certificate.
• This process is separate from the standard firearm certificate issued by a Superintendent for an unrestricted firearm: it sits at a higher level of authority, precisely because the device is treated as a firearm in its own right.

Enforcement of this point has visibly tightened since 2022–2023. The Department of Justice reminded Registered Firearms Dealers that these sights are Restricted Firearms under the Act, after Customs intercepted a number of night vision sights imported from the UK and Northern Ireland without the corresponding authorisations. Many holders of legally registered firearms found themselves in possession of equipment not covered by a valid authorisation — a situation the authorities have since asked to be regularised.

In practice: the same device (a thermal sight, for example) is unrestricted for handheld use, but becomes a Restricted Firearm the moment it is fitted — or even simply designed to be fitted — to a rifle or shotgun.

Night hunting: the Wildlife Act strictly governs deer

The second pillar of the Irish regime concerns hunting methods, independent of how the equipment is classified under the Firearms Act:

• Section 29 of the Wildlife Act 1976 prohibits hunting deer outside the window running from one hour before sunrise to one hour after sunset, and only during permitted Open Seasons.
• The same section explicitly prohibits the use of a lamp for hunting deer — a prohibition that, in spirit, extends to any artificial light or night-vision aid used to locate and shoot the animal.
• Sections 23 and 42 of the Wildlife Act allow, as an exception, night culling of deer for population management or damage control, under a licence issued by the National Parks and Wildlife Service (NPWS). Under strict conditions, these licences may permit the use of a lamp or a night vision device.
• For fox and other species classified as pests, there is no close season as strict as for deer, but using a firearm fitted with a night vision or thermal sight still requires the Restricted Firearm Certificate described above, regardless of species.

Night-time deer poaching "by lamp" remains an issue flagged by the NPWS; field enforcement has increased alongside the tightening of Firearms Act enforcement.

What buyers in Ireland should take away

• A handheld night vision monocular or binocular, such as the LNVM or LAB-NVS, can be used in Ireland without any special authorisation, for observation, security, hiking, or any professional activity that doesn't require mounting on a firearm.
• Any plan to mount the device on a firearm systematically requires an administrative process with An Garda Síochána (Form FCA1, Divisional Chief Superintendent) — including for devices imported from the UK or Northern Ireland.
• Night hunting remains a separate framework governed by the Wildlife Act: banned for deer outside a specific NPWS licence, more flexible for pest species, but still subject, on the equipment side, to Firearms Act rules whenever a weapon is involved.
