Office Access Control Systems: Fobs, Keypads and Video Door Entry Explained

Traditional keys may be suitable for a small office with only a few employees, but they can become difficult to manage as a business grows.

Keys can be lost, copied or passed between staff. When somebody leaves the company, it may not always be clear whether every key has been returned. Shared offices, sensitive departments and buildings with regular visitors can create even more complicated access requirements.

Office access control systems provide businesses with a more manageable way to decide who can enter the premises and which areas they are permitted to access.

From proximity fobs and keypads to video door entry, there are several options available. The right choice depends on the layout of your office, the number of users and the areas that need protecting.

What Is An Office Access Control System?

An access control system replaces or supports traditional keys with an electronic method of managing entry.

Instead of unlocking a door with a physical key, authorised users may enter using:

• A proximity fob
• An access card
• A PIN code
• A video door entry system
• A remotely released entrance

The system controls the door electronically and only releases it when approved access is provided.

This can make it easier for a business to add or remove users, manage several entrances and restrict access to sensitive parts of the premises.

Office access control may be used at the main entrance or across several internal areas, including management offices, server rooms, finance departments and document stores.

Our Office Security Systems page explains how access control can work alongside CCTV, intruder alarms and video door entry as part of a wider commercial security solution.

Why Traditional Office Keys Can Become Difficult To Manage

Keys provide a straightforward way to secure a door, but they offer limited control once they have been issued.

Common problems include:

• Keys being lost or misplaced
• Unauthorised copies being made
• Uncertainty over whether departing employees returned their keys
• Several people sharing the same key
• Locks needing to be changed after a security concern
• Different keys being required for multiple parts of the building

Electronic access control can remove the need to replace locks every time a fob or card goes missing. The affected credential can usually be removed from the system while access for other users continues as normal.

It also allows the business to decide which doors each person can use rather than giving everybody the same level of access.

Proximity Fobs And Access Cards For Office Staff

Proximity fobs and cards are among the most common access-control options for offices.

An employee presents their assigned fob or card to a reader beside the door. If their credentials are approved, the door releases and allows them to enter.

This can work well for:

• Main staff entrances
• Individual office suites
• Shared commercial buildings
• Server and communications rooms
• Management offices
• Stock and equipment rooms
• Staff car parks and external gates

Access permissions can be tailored to different roles. For example, all employees may be able to enter the main office, while only selected staff can access finance records, IT equipment or senior management areas.

When somebody leaves the business, their fob can be removed without affecting the access of other employees.

Are Office Keypad Systems A Good Option?

A keypad allows authorised users to enter by typing a PIN code.

This can provide a practical solution where issuing individual fobs is unnecessary or where approved contractors and staff need access to a particular entrance.

Keypads may be suitable for:

• Smaller offices
• Staff-only entrances
• Internal restricted rooms
• Shared facilities
• Areas used by regular contractors

However, codes need to be managed carefully. A code can be shared with somebody who is not authorised, and businesses should avoid allowing the same PIN to remain unchanged after staff leave.

Where stronger individual accountability is required, assigned fobs or cards may be more appropriate than one shared keypad code.

How Video Door Entry Helps Offices Manage Visitors

Employees are not the only people who may need to enter an office.

Clients, delivery drivers, contractors, interview candidates and other visitors may arrive throughout the working day. Allowing unrestricted entry may be unsuitable, particularly where the building does not have a permanently staffed reception.

A video door entry system allows an authorised member of staff to see and speak to the visitor before releasing the entrance.

A typical system may include:

• An external video door station
• A call button or directory
• An integrated camera and microphone
• An internal touchscreen monitor
• A remotely controlled door lock
• Keypad or fob access for authorised staff
• Internal press-to-exit controls

The visitor requests entry at the door station. A member of staff can then view the person, speak to them and decide whether to release the entrance.

This gives genuine visitors a clear way to contact the business while preventing the office door from being left open or unlocked unnecessarily.

Access Control For Shared Offices And Business Centres

Shared offices and multi-tenant business centres can have particularly complex access requirements.

Employees from several organisations may use the same main entrance, reception and communal areas, while each company needs to keep its own office suite secure.

Access control can be configured so users can enter:

• The main building
• Shared communal spaces
• Their organisation’s office suite
• Approved meeting rooms
• Car parks or external gates

They can remain restricted from other tenants’ offices and sensitive building-management areas.

This provides a more practical solution than distributing several physical keys to every employee.

Protecting Sensitive Office Areas

Office security is not only about controlling entry through the front door.

Some rooms may contain information, equipment or systems that should only be accessible to specific employees.

Access control may be considered for:

• Server and communications rooms
• Finance departments
• Personnel and HR records
• Document archives
• Management offices
• Security equipment rooms
• Cash-handling areas
• Storage rooms containing valuable equipment

Permissions can be set according to job roles, helping the business limit unnecessary access while allowing authorised employees to work normally.

CCTV may also be positioned to monitor the entrance to a restricted room, providing visual evidence alongside the access-control records if an incident needs to be reviewed.

Can Office Access Be Restricted By Time?

Some electronic access-control systems can be configured around working hours or approved access periods.

This may be useful where:

• Most employees only need access during standard office hours
• Cleaners or contractors attend at set times
• Specific departments operate evening or weekend shifts
• A shared building has different opening arrangements for each tenant

The exact options depend on the system selected and how the office operates.

Time-based permissions can help reduce unnecessary access outside normal hours without requiring somebody to manually unlock and secure every area.

Using Access Control With Office CCTV

Access control and CCTV perform different roles, but they can complement one another.

The access-control system manages whether a user can open a particular door. CCTV provides a visual record of activity around that entrance.

Together, they may help a business review:

• Who approached or entered an office
• Whether a fob was used by the assigned employee
• Visitor activity around the reception entrance
• Unauthorised attempts to follow somebody through a controlled door
• Incidents near restricted areas

Professionally planned commercial CCTV systems can provide coverage around entrances, reception areas, car parks and approaches to sensitive office rooms.

Using Access Control With An Office Intruder Alarm

An access-control system manages authorised entry, while an intruder alarm protects the premises when selected areas should be unoccupied.

For example, employees may use fobs to enter the office during the day, while the alarm protects the building overnight.

Larger offices may also be divided into separate alarm zones. This allows one department or floor to remain in use while another area is secured.

Combining access control with a professionally installed commercial intruder alarm can provide several layers of protection rather than relying on one system alone.

Can Existing Office Access Control Be Upgraded?

A complete replacement is not always necessary.

Businesses may already have electronic locks, keypads or video entry equipment that can be repaired, expanded or upgraded.

An assessment may identify opportunities to:

• Replace failed door readers
• Add access control to more entrances
• Improve visitor video quality
• Introduce individual fobs instead of shared codes
• Add internal touchscreen monitors
• Improve controlled exit arrangements
• Connect access points with CCTV coverage

The available options will depend on the condition, compatibility and age of the existing equipment.

Signs Your Office Access System Needs Reviewing

It may be time to review access arrangements if:

• Too many physical keys are in circulation
• Staff regularly share access codes
• Lost fobs or cards have not been removed
• Former employees may still have access
• Visitors can enter without speaking to staff
• Sensitive rooms rely on doors that are often left unlocked
• The business has expanded into additional rooms or floors
• The current video entry picture or audio is unreliable
• Door-release equipment has developed faults

Changes to staffing, office layouts and working hours can all affect whether the original security setup remains suitable.

Office Access Control Maintenance And Support

Electronic entry systems need to remain dependable throughout the working day.

A faulty reader, unreliable lock or damaged release button can cause disruption as well as creating a security concern.

Maintenance may include checking:

• Fob and card readers
• Electronic locks
• Video door stations
• Internal monitors
• Press-to-exit controls
• Emergency door-release equipment
• Power supplies and connections
• User permissions and system operation

Our wider security system maintenance service includes fault finding, repairs and support for commercial security equipment across Greater Manchester.

Choosing The Right Office Entry System

There is no single access-control system that will suit every office.

The right solution depends on:

• The number of employees and visitors
• The number of doors requiring control
• Whether the building has a reception
• The areas that need restricted access
• Working hours and contractor access
• Whether several businesses share the building
• Existing CCTV and alarm systems
• Future expansion plans

A small office may only need a video intercom and keypad at the main entrance. A larger workplace may benefit from individual fobs, multiple controlled doors and different access permissions for each department.

Frequently Asked Questions

What is the best access-control system for an office?

The right system depends on the number of users, entrances and restricted areas. Common options include proximity fobs, cards, keypads and video door entry.

Are fobs more secure than office keys?

Fobs are easier to manage because a lost or unreturned credential can usually be removed without replacing the door lock. Permissions can also be limited to selected entrances.

Can video door entry work without a receptionist?

Yes. Calls from the entrance can be answered by an authorised member of staff using an internal monitor. The employee can see and speak to the visitor before releasing the door.

Can different employees have different access permissions?

Yes. Access can be configured according to the user’s role, allowing selected staff to enter sensitive rooms while restricting access for others.

Can access control be added to an existing office?

In many cases, yes. Existing doors and entry systems can be assessed to determine whether access control, keypad entry or video intercom equipment can be installed or upgraded.

Does access control replace an office alarm?

No. Access control manages authorised entry, while an intruder alarm detects access or movement when protected areas should be empty. Many offices benefit from using both systems.

Can office access control work with CCTV?

Yes. CCTV can provide visual coverage around controlled entrances and sensitive areas, helping businesses review incidents alongside access records.

Do office access-control systems need maintenance?

Yes. Readers, locks, monitors, power supplies and release controls should be checked if faults develop or as part of a planned commercial security maintenance programme.
