5 Overlooked Security Vulnerabilities in Commercial Buildings (and How Michigan Businesses Can Fix Them)

Most commercial properties rely on a mix of cameras, access control, alarms, and networking equipment. But even with a solid foundation, many buildings across Ann Arbor, Ypsilanti, Saline, Dexter, and Southeast Michigan still have hidden security gaps that can lead to break-ins, liability claims, or operational disruptions.

At Tier One Technologies, we routinely evaluate systems for local businesses — and we see the same overlooked vulnerabilities again and again. Here are the top issues and how to fix them.

1. Blind Spots Around Entrances and Parking Areas

The most common vulnerability is simple:
Cameras don’t cover the areas where incidents actually occur.

Blind spots typically appear:

  • Near side doors or employee entrances

  • Back alleys and dumpsters

  • Loading docks

  • Stairwells and corners

  • Parking lot drive lanes

Fix:
A professional layout ensures coverage where it counts, including wide-angle views, multi-sensor cameras, and proper mounting heights for Michigan weather conditions.

2. Unsecured Network Closets and Equipment Rooms

IT closets are one of the most targeted areas in commercial buildings. Unfortunately, many are protected by:

  • A basic office doorknob

  • A shared master key

  • Or no lock at all

If someone gains access, they can disable cameras, disconnect access control, or steal equipment.

Fix:
Use access control on all critical rooms and audit who goes in and out. Never leave networking or security hardware in unlocked closets.

3. Outdated Access Control or Traditional Keys

Many Michigan businesses still rely on metal keys, which can be:

  • Duplicated

  • Lost

  • Shared between employees

  • Used even after someone stops working there

This creates major liability.

Fix:
Modern access control systems allow instant credential changes, mobile credentials, audit trails, and secure door management.

4. Poor Lighting in High-Risk Areas

Even the best cameras struggle without proper lighting — especially during Michigan winters with early sunsets and low visibility.

Problem areas often include:

  • Parking lots

  • Walkways

  • Dumpster enclosures

  • Loading docks

  • Rear employee entrances

Fix:
Combine proper lighting with cameras designed for low-light performance. The difference in clarity is significant.

5. No Integration Between Cameras, Access Control, and Alarms

When systems don’t communicate, businesses lose critical insight.
For example:

  • A door alarms after hours, but you don’t see the video automatically

  • An employee badge is used, but you can’t verify who actually entered

  • A camera captures activity, but no alert is triggered

Fix:
Integrated security platforms tie everything together and create a complete, real-time picture of what’s happening around the property.
