Multi-building campus security systems create uniquely complex access control challenges. In fact, access control systems are often the most difficult security systems to manage across a multi-building campus.
With a single-building system, even a complex one with multiple levels of access, you have at least a clearly defined perimeter. But securing a campus with dozens of buildings and hundreds of access points requires thoughtful campus security system design and is orders of magnitude more difficult.
Take the University of Wisconsin: UW’s stunning 936-acre campus features 157 buildings. The university serves around 50,000 students, and thousands more faculty and staff travel to and from the campus each day.
Adding to the challenge, unlike some campuses that are closed or secluded, the UW campus sits in the middle of Downtown Madison, with dozens of roads and pathways criss-crossing the campus. And all of this must be secured by one relatively small Access, Video, and Infrastructure Security (AVIS) team.
This post walks through the unique challenges of multi-building campuses like UW’s. Effective multi-building campus security depends on a unified approach to security system design, access control, and physical security planning. We’ll also give you a step-by-step plan for how to design multi-building security systems that are thorough, resilient, future-proof, and actually manageable.
The Access Control Problem Multiplies with Every Building
Every building added to a campus security system is an additional layer of complexity. The aspects of access control that aren’t working well at one size get exponentially worse as building count increases.
Managing a campus security system in spreadsheets or paper floor plans grows more and more untenable as you add access control systems, video surveillance, security technology, or buildings.
Some organizations look to solve this problem by adding more hardware, but hardware without the right systems only adds more complexity.
Instead, the fix is designing one unified digital canvas that campus security leaders, system integrators, and other stakeholders can collaborate on. This approach improves security system planning, helping campus security leaders standardize documentation and collaborate throughout the lifecycle of their physical security systems. From there it’s possible to validate coverage before installation and then to maintain a single up-to-date as-built that grows along with the campus.
For the University of Wisconsin, spreadsheets and institutional knowledge weren’t sufficient at their scale. UW’s AVIS team needed a more powerful solution for system design and lifecycle management, one that also handles the same for video surveillance needs.
Ultimately, UW found a tech-forward solution that gave them a powerful, living digital as-built and provided what they needed for both system design and lifecycle management. (Read the full case study.)
Heads up, system integrators: UW isn’t alone. This market is too meaningful to ignore: Higher-education campuses captured 42.19% of the education security market in 2025, and 39% of those institutions include access control (source: Mordor Intelligence).
Why Multi-Building Campuses Are a Different Design Problem
Multi-building campuses seem almost as difficult as possible: they have no single perimeter (and may not have a functioning perimeter at all, as is the case for UW’s campus at large), dozens if not hundreds of entrances, and constituents with widely varying access needs.
There are also mechanical challenges. Especially in higher education, multi-building campuses often include structures built decades apart from one another. Each may have different door hardware and almost certainly will have different wiring.
Additionally, not every building has the same risk profile or access control requirements.
To top it off, campuses rarely stop building, renovating, updating, and modifying their buildings.
Before System Surveyor, UW’s AVIS team managed 5,000+ access control points using Excel files and shared drive folders, all held together with institutional knowledge.
Patrick Bucci, Access Control Program Supervisor at UW, describes the challenge they faced:
“In the past, we relied on a lot of manual data entry: excel files, folders upon folders in a shared drive. Beyond all that, though, the bulk of our approach to lifecycle management came down to institutional knowledge. The longer you worked at the University, the more familiar you were with each building on campus. Obviously, that’s not a sustainable model.”
6 Steps to Better System Design for Multi-Building Campuses
UW identified the problems around multi-building security and access control, then they isolated what needed to change. Next, they looked for a technology solution to bring it all together.
Here’s a crash course on how UW modernized its system design processes to resounding success — and how System Surveyor made it possible.
1. Start With One Campus-Wide Access Control System Plan, Not a Building-by-Building Patchwork
Instead of working building by building, put everything in one context. Import satellite imagery or floor plans for every building into one project, where security teams and stakeholders can compare and cross-reference side by side.
Patrick Bucci explains the problem they faced before adopting this approach at UW:
“Whenever a concern was raised before, we had to walk over to the building, physically survey and assess the devices we had deployed, and then go from there.”
But with a unified campus-wide access control plan, exceptions and inconsistencies become much more visible. By building that plan in a collaborative cloud-based platform like System Surveyor, you’ll enable new levels of collaboration: instead of emailing endless PDF markups, your security team, integrators, and facilities staff work from the same live design.
Using System Surveyor, you can also use pre-configured Element Profiles (or create your own), allowing you to document access control units consistently across spaces. Interior doors in the library and in the science building operate consistently because they run using the same elements under the same Element Profile.
Layering is one more advantage of a digital unified system design. With system-type layering, you can get as detailed or as high-level as you need. Drill into all systems access control, video, intrusion) within an individual building, or zoom out to the entire campus and view just access control.
Patrick again:
“With System Surveyor, we have one central resource we can access that offers us a detailed visual for reference. Before we even show up, we know exactly what needs to be done.”
2. Validate Coverage Before You Install: Designing With Boundaries
Cameras, motion detectors, and sensors don’t see through walls, breezeways, courtyards, or the building next door.
On a 157-building campus, a coverage gap between two structures is invisible in a spreadsheet and expensive to discover after installation.
With Boundaries in System Surveyor, you can indicate walls and obstacles directly on the digital floor plan or campus map, then place devices. Coverage cones automatically crop to the true field of view, revealing potential blind spots during design, not after installation.
System Surveyor CEO Chris Hugman: “System Surveyor Boundaries is a game-changer for our integrator, corporate and campus customers. With this powerful, easy-to-use tool, we’re giving users the ability to visualize the effect of walls, obstacles and other coverage limitations on a host of critical devices… enabling businesses to see the true view and coverage which makes for more informed, confident decisions.”
3. Match the Right Camera to Each Access Point with Camera Advisor
A campus like UW needs different camera capabilities in different spaces. You may need recognition-level resolution for building entrances, while parking garages and lots may need only detection.
Camera Advisor runs on the DORI framework (Detection, Observation, Recognition, Inspection), giving security teams and integrators a powerful two-way tool for matching cameras to needs. Either choose a camera and see its effective resolution at a given distance, or set a desired quality level for a camera point and get camera recommendations.
4. Design for Access Control Hardware at Scale
More than any other, access control systems dominate among security technologies on school and college campuses. But the sheer number of access points can create logistical headaches.
UW’s AVIS unit manages more than 5,000 access control points including biometric scanners and scheduling systems, and every construction project adds more to that total.
Instead of building these one at a time, build a single fully-specified door container (that includes reader, lock, credential type, and/or biometric scanner) and redeploy it across every similar access point. Where a manual approach looks like documenting 100 doors, this digital approach reduces the work to just a handful of door types and specs.
In System Surveyor, duplicated elements instantly feed an automated bill of materials, keeping budgeting accurate at any scale.
5. Leverage Relationships Better with Vendors and Integrator Partners
This approach to system design enables collaboration both internally (such as with public safety) and externally, with system integrators and even vendors. Because these other groups can interact with a system design, security systems become sharper, more cohesive, and more powerful.
This level of collaboration also helps campuses order and access the right products at the right time with greater efficiency.
6. The Real Payoff: A Living Digital As-Built and a Better Experience on Campus
The real payoff extends far beyond winning the design phase. Organizations gain a living digital as-built that supports every phase of the security system lifecycle. What this approach makes possible is a true living digital as-built: one file per building or campus that holds device specs, product costs, layout, and contacts, updated as the system changes.
Patrick explains the long-term value:
“With System Surveyor, we have one central resource we can access that offers us a detailed visual for reference. Before we even show up, we know exactly what needs to be done.”
A digital as-built also supports organizations into the future.
- A current as-built (not a PDF from the original install) shows a renovation team what’s already deployed before scoping an upgrade.
- A dynamic as-built protects against institutional knowledge drain when staff retire or move on: information no one else remembers is safely stored in the as-built.
UW looks at their system design this way, seeing it as more than just a record of what they installed but as a foundation for whatever gets deployed next. Successful multi-building campus security systems rely on standardized access control design, collaborative planning, video surveillance, and a continuously updated digital as-built.
Design Checklist for Multi-Building Campuses
To recap, these are the six steps most crucial for modern multi-building security system design:
- Put every building on one connected digital floor plan, not on separate files per building.
- Standardize your access control hardware specifications so every door is documented consistently.
- Use Boundaries to confirm real-world coverage during design to avoid costly rework at installation.
- Use Camera Advisor to match camera resolution to each access point’s needs.
- Duplicate access point containers to scale designs and budgets accurately at any scale.
- Maintain one digital as-built and keep it current through every renovation and upgrade.
