How to Plan a Commercial Access Control System

Planning a commercial access control system involves much more than choosing a card reader or keypad.

A properly planned system should consider the people using the building, the doors being controlled, the type of credentials being issued, the electronic locking hardware, access schedules, emergency egress, system administration, future expansion, and how access control may interact with other security systems.

For businesses, warehouses, offices, manufacturing facilities, schools, healthcare properties, municipal buildings, and other commercial environments, taking time to plan the system before equipment is selected can help reduce unnecessary complexity and make the system easier to manage over time.

This resource provides an overview of the major questions organizations should consider when planning commercial access control.

Start With the Doors

The first step is identifying which doors actually need electronic access control.

Not every opening in a facility needs to become a controlled door.

Common candidates include:

• Employee entrances
• Main office entrances
• Rear entrances
• Interior restricted doors
• IT and server rooms
• Storage rooms
• Maintenance areas
• Warehouse entrances
• Production areas
• Management offices
• Contractor entrances

For each door, consider why access needs to be controlled.

The goal may be to reduce traditional key use, restrict certain departments, improve employee management, create an activity history, control after-hours entry, or prevent access to sensitive areas.

Understanding the purpose of each opening helps determine what equipment and permissions may be required.

Identify Who Needs Access

Next, determine who will use the system.

Potential users may include:

• Employees
• Managers
• Contractors
• Cleaning personnel
• Vendors
• Temporary workers
• Maintenance personnel
• Visitors

Different groups may require different access privileges.

A warehouse employee, for example, may need access to an employee entrance and production area but not the server room.

A cleaning contractor may only require access during specific evening hours.

Planning user groups before programming begins can make credential management much easier.

Choose the Appropriate Credential Type

Commercial access control can use several types of credentials.

These may include:

• Cards
• Key fobs
• Mobile credentials
• PINs
• Keypads
• Card-and-PIN combinations

The right credential depends on the facility and the number of users.

Cards and fobs are commonly used where individual accountability is important.

Keypads can be practical for selected entrances or smaller groups.

Mobile credentials may be appropriate where organizations want centralized electronic credential management.

Higher-security areas may use more than one authentication method.

Plan Individual Credentials

Whenever practical, commercial users should generally have individually assigned credentials rather than sharing one permanent code.

Individual credentials make it easier to:

• Remove former employees
• Change permissions
• Assign schedules
• Restrict individual doors
• Review activity
• Manage temporary users

If everyone shares one access code, it becomes much more difficult to identify who entered a door or remove a single person’s access.

Evaluate the Existing Door Hardware

The access-control reader is only one part of the controlled opening.

The physical door, frame, lock, closer, exit hardware, and surrounding conditions should also be evaluated.

Electronic access may require components such as:

• Electric strikes
• Electrified locks
• Electrified exit devices
• Magnetic locks
• Door-position switches
• Request-to-exit devices
• Power supplies
• Door closers

A door that does not close or latch correctly can create problems even when the access-control electronics are functioning properly.

Door condition should therefore be reviewed before the locking hardware is selected.

Consider Emergency Egress

Access control should restrict unauthorized entry without preventing occupants from safely exiting the building.

Depending on the type of opening, planning may need to consider:

• Exit devices
• Fire-alarm interaction
• Emergency release
• Request-to-exit operation
• Accessibility
• Applicable building and fire requirements

Electronic locking decisions should be made around the complete door opening rather than simply the desired method of entry.

Decide Whether Central Management Is Needed

A single controlled door may be manageable with a relatively simple system.

As the number of doors, employees, departments, or buildings grows, centralized administration becomes more important.

A centrally managed system may allow administrators to control:

• Users
• Credentials
• Door permissions
• Schedules
• Activity records
• Multiple buildings
• Multiple locations

Businesses expecting future growth should consider expansion before selecting a system that may become difficult to manage later.

Create Access Schedules

Not every authorized credential needs to work at every time of day.

Access schedules can help organizations control when users are permitted to enter.

For example:

• Employees may have weekday access.
• Managers may have extended hours.
• Cleaning contractors may have evening access.
• Temporary contractors may receive access only for the duration of a project.

Planning schedules in advance can reduce the need for manual locking and unlocking and provide more consistent control.

Plan for Employee Turnover

Credential removal should be part of the access-control plan from the beginning.

When an employee leaves, a business should have a clear procedure for disabling that person’s credential.

The same applies to contractors, vendors, temporary users, and other individuals who no longer require access.

A basic process may include:

• Disabling the credential
• Reviewing assigned doors
• Removing temporary permissions
• Checking shared access groups
• Updating administrative records

Old or unidentified credentials should not remain active indefinitely.

Consider Door Monitoring

Access control can do more than unlock doors.

Depending on the system, door-position monitoring may provide information about conditions such as:

• Door opened
• Door closed
• Door held open
• Forced-door event

These events can help administrators understand whether a controlled opening is operating as intended.

Door monitoring may be particularly useful for exterior entrances, restricted areas, warehouses, and other higher-priority openings.

Consider Video Surveillance Integration

Some organizations may benefit from coordinating access control with video surveillance.

An access event can indicate that a credential was used at a particular door and time.

Video may provide visual context for what actually occurred.

This can be useful when investigating:

• Forced entry
• Unauthorized access
• After-hours activity
• Door-held-open events
• Credential misuse

Integration should be considered where it provides a clear operational benefit rather than simply adding unnecessary complexity.

Consider Intrusion and Intercom Integration

Access control may also operate alongside intrusion detection and intercom systems.

Examples may include:

• Visitor communication at a secured entrance
• Remote door release
• Gate entry
• After-hours access
• Restricted-area monitoring
• Coordination with intrusion alarms

Organizations planning multiple security systems should consider how each technology will be administered and used together.

Plan for Expansion

A system that works for five employees and two doors may not be appropriate for a company that expects to grow to several buildings or locations.

Future planning should consider:

• Additional doors
• More employees
• New departments
• Additional buildings
• Multiple locations
• Mobile credentials
• Cloud management
• Video integration
• Gate access
• Visitor management

Selecting an architecture with reasonable room for expansion can reduce the need for unnecessary replacement later.

Consider Cloud, On-Premise, and Hybrid Management

Commercial access-control systems may be managed through different architectures.

Cloud-managed platforms can provide centralized remote administration.

On-premise systems may provide local control for organizations with specific infrastructure or IT requirements.

Hybrid environments may combine local door control with centralized management capabilities.

The right approach depends on the organization’s operational, IT, cybersecurity, and administrative needs.

Build a Credential Management Policy

Technology alone does not create an effective access-control program.

Organizations should also establish policies covering:

• Who can issue credentials
• Who can change permissions
• How former employees are removed
• How temporary users are handled
• How lost credentials are reported
• How access schedules are assigned
• How administrators are authorized

Clear procedures become increasingly important as the system grows.

Planning a Commercial Access Control System

The most effective access-control projects begin by understanding the property and its users before selecting equipment.

Businesses should identify:

• Doors that require control
• Users who require access
• Credential types
• Door hardware
• Access schedules
• Emergency egress requirements
• Monitoring needs
• Integration requirements
• Administration responsibilities
• Future expansion

The goal is to create a system that supports the daily operation of the facility while providing practical control over who can access specific areas and when.

Frequently Asked Questions

What should be planned first in an access-control project?

Start by identifying which doors require control, who needs access, and what operational or security problem the system needs to solve.

Does every commercial door need access control?

No. Electronic access is generally most useful on entrances and restricted areas where improved credential management or accountability is needed.

Should employees share one credential?

Individual credentials are usually easier to manage because permissions can be changed or removed for one person without affecting everyone else.

Can access control limit when someone enters?

Yes. Many systems allow credentials to operate according to specific days and times.

Can an existing access-control system be expanded?

Many systems can be expanded, but compatibility, controller capacity, reader technology, software, licensing, and existing infrastructure should be evaluated first.

Can access control work with video surveillance?

Yes. Depending on the platform, access events may be associated with video to provide additional context during investigations.

Should future growth be considered during planning?

Yes. Expected increases in users, doors, buildings, and locations should be considered before selecting the system architecture.
