Campus security and physical perimeter for a Swedish hyperscale hall

Reading order

Start with the legal door, not with the fence. Write whether anyone has actually decided that the activity is of importance to Sweden’s security, or whether you are only looking at ordinary physical protection, cameras and a plan. A documented säkerhetsskyddsanalys is a duty for security-sensitive activity. It is not a marketing appendix and not a finding that every hyperscale hall is in scope. This register does not publish a list of halls that sit inside that door.

Then split cameras from fences. IMY’s April 2025 pages say the permit duty is gone. They also say private companies often never needed an IMY permit, including camera surveillance of fenced areas closed to the public, and that the absence of a permit never made the surveillance automatically lawful. An interest-balancing assessment still comes first. The Camera Surveillance Act and the GDPR remain the statute pair. A camera drawing is not a protective-security clearance.

Only then open the standard and the plan. EN 50600-2-5 writes Protection Classes per space — generator yard, transformer, white space — after a risk analysis, and it lists lighting, video, access control and intrusion detection as technology families. CEN-CENELEC’s Green Data Centres page already places that part in the 50600 series. Boverket’s plan pages decide use, height and whether a fence is even allowed on that prickmark. Do not paste a Protection Class onto a detaljplan as if they were one permit.

• Scope under the Protective Security Act before any fence slogan.
• Camera interest-balancing is not an IMY permit and not a security clearance.
• EN 50600 Protection Classes attach to spaces, not to a whole campus.
• The reporting page already owns the 500 kW filing exception.

What a perimeter file actually is

A perimeter file is a stack of dated papers around land, cameras and, sometimes, protective security. The 2018 Act does not name data centres. It names security-sensitive activity. Säkerhetspolisen’s guidance says the analysis must answer what must be protected, against whom and with which measures, and that measures then follow the activity’s nature, the presence of classified information and other circumstances. A later security-protection agreement with a supplier is a different chapter of the same Act. It is not a fence catalogue.

Ordinary physical protection can exist without that door. A private campus can still have a fence, lighting and guards because the owner wants them, because an insurer asks, or because a tenant contract says so. Those commercial papers are not cited here as a Swedish statutory height. EN 50600-2-5 is the vocabulary for talking about spaces and residual risk — tolerate, treat, transfer or terminate — after the owner’s risk acceptance. A Protection Class is not a Swedish police certificate.

Cameras have their own clock. IMY says activities themselves now decide whether planned surveillance is allowed, that an interest-balancing assessment is documented especially when a public-interest task is in play, and that old IMY permits can serve as that documentation if the surveillance has not changed in a material way. Fenced areas closed to the public were already usually outside the old permit duty. They were never outside the GDPR.

The plan remains a land-use machine. A wall, a gatehouse or a camera pole can be a building-permit object. A prickmark can forbid a building on the perimeter strip. Boverket’s height page separates nockhöjd from totalhöjd; a mast or a camera column is not automatically the hall’s roof. Foreign-investment screening under ISP, already in this register, is another door again. It is not a perimeter drawing.

What named primary sources show

The Protective Security Act shows the security-sensitive-activity door and the documented-analysis duty. Säkerhetspolisen’s guidance shows the method and points to the 2021 ordinance and PMFS 2022:1. The Camera Surveillance Act and IMY’s April 2025 pages show that the IMY permit duty has ended and that interest-balancing remains. EN 50600-2-5 and the CEN-CENELEC Green Data Centres page show Protection Classes as a space-level vocabulary.

Boverket’s detailed-plan pages show use, height and land-use limits that can hit a fence line. Lag (2025:570), on the reporting page, shows a Protective Security Act exception from the 500 kilowatt filing duty. ISP’s screening pages remain a transaction door, not a perimeter. This page will not invent a civil name, a hall list or a statutory fence metre.

A matrix instead of one fence height

The table is a permission table. A filled cell is a claim the named URL can carry. An empty cell means this page will not invent the missing Swedish standoff.

Do not add a Protection Class to an IMY interest-balancing note and a Protective Security Act analysis and call the sum a campus permit. Those remain different objects.

Common misreads

The first misread is to treat every hyperscale hall as automatically security-sensitive. The Act names activity of importance to Sweden’s security, not a building type. The second is to treat the end of the IMY permit as the end of camera law. Interest-balancing and the GDPR remain. The third is to treat an EN 50600 Protection Class as a Swedish decision.

The fourth is to invent a fence height or a standoff because a foreign campus brochure published one. No source here publishes a Swedish metre. The fifth is to treat the 500 kilowatt reporting exception as a public register of secret halls. The sixth is to staple ISP screening onto a camera pole and call them one security permit.

What to ask next

If a brief prints a Swedish campus-security standard, ask which named URL uses that sentence for protective-security scope, camera interest-balancing, an EN 50600 space class or a plan object. If the URL only shows a foreign fence height or a marketing “secure campus” line, the brief has already left the source.

Then open the reporting page, the foreign-investment-screening page and the detailed-plan page. Those pages already own the filing exception, the transaction door and the land-use machine. This page only asks whether the perimeter objects are named.

1. Has anyone actually placed the activity inside the Protective Security Act?
2. Is the camera file an interest-balancing note, or a missing IMY permit from before 1 April 2025?
3. Which space holds which EN 50600 Protection Class?
4. Does the adopted plan even allow the fence on that strip?
5. Has a Swedish fence metre been invented?

What this does and does not prove

This page proves that Swedish primary sources already split campus security into protective-security scope, camera law, a European space-class vocabulary and a plan object, and that none of those doors publishes a national fence height. It proves that the IMY permit duty ended on 1 April 2025.

It does not prove that a named Swedish hall is security-sensitive. It does not invent a standoff metre. It does not treat a Protection Class as a police certificate.

Empty cells stay empty. Until a later primary source names a Swedish hall’s doors with dated papers and a boundary, the perimeter stays a method, not a census.
