This guide explains the main types of access control systems in Essex in plain terms, so you can work out which one suits your property best.
What Is an Access Control System?
An access control system is a way of managing who can enter a building, room, or area. It lets the owner decide who gets in, when they can get in, and keeps a record of every entry attempt. No more lost keys, no more changing locks every time a member of staff leaves.
These systems work for all kinds of properties, from a family home in Chelmsford to a warehouse in Basildon or an office in Colchester.
The Main Types of Access Control
1. Fob and Card Entry (Token-Based Systems)
This is one of the most popular options for businesses. Each person is given a small card or key fob. When they hold it near a reader on the door, the system checks whether that fob is allowed in. If it is, the door unlocks.
The big advantage is how easy it is to manage. If someone leaves the company, you simply remove their fob from the system. No need to change the locks. Cards can also be set to work only during certain hours, which is useful for shift-based workplaces.
Best for: offices, shops, warehouses, and any site with multiple staff members.
2. Keypad Access (PIN Entry)
With a keypad system, users type a PIN code to unlock the door. This is a simple and reliable option. Different people can be given different codes, and codes can be changed regularly to keep things secure.
Keypad systems are often used on residential properties and smaller commercial sites where fewer people need access. They do not require any physical token, so there is nothing to lose or forget, as long as you remember your PIN.
Best for: family homes, small offices, and secondary entrances where visitor access is occasionally needed.
3. Biometric Access Control
Biometric systems use something unique about your body to verify who you are. The most common type uses fingerprint recognition. Some systems use facial recognition instead.
Because your fingerprint or face cannot be copied as easily as a key or a card, biometric access control offers a higher level of security. It also means there is nothing to carry or remember. The downside is that these systems tend to cost more and can be slightly slower at busy entry points.
Best for: high-security areas such as server rooms, stock rooms, data centres, and any location where it is critical to know exactly who entered.
The National Cyber Security Centre (NCSC) provides useful guidance on identity and access management, including how biometric authentication can form part of a layered security approach.
4. Video Door Entry Systems
Video door entry lets you see and speak to a visitor before you let them in. A camera and intercom are fitted at the entrance. The person inside can see who is at the door on a screen or their phone, then choose whether to unlock the door remotely.
This is a popular option for residential properties, blocks of flats, and reception areas where you want to screen visitors before granting access.
Best for: homes, residential blocks, and front-of-house business entrances.
5. Smart Access Control (App-Based Entry)
Modern smart systems connect to your smartphone. You can unlock doors remotely, grant temporary access to a visitor, and receive a notification every time someone enters. Some systems use Bluetooth or mobile credentials instead of a physical fob.
This kind of system suits property owners or managers who are not always on site but want to stay in control of who comes and goes.
Best for: landlords, business owners who manage multiple sites, and any property where remote access management is useful.

Comparison Table: Which System Is Right for You?
| System Type | How It Works | Best For | Level of Security |
|---|---|---|---|
| Fob / Card Entry | Tap a card or fob on a reader | Offices, warehouses, multi-staff sites | Medium to High |
| Keypad / PIN | Enter a code on a pad | Homes, small offices | Medium |
| Biometric | Fingerprint or face scan | High-security areas | Very High |
| Video Door Entry | Camera and intercom with remote unlock | Homes, flats, reception areas | Medium |
| Smart / App-Based | Control via smartphone | Remote management, landlords | Medium to High |
Can Access Control Work Alongside Other Security?
Yes, and it works very well when combined with other security measures. Many Essex homes and businesses pair access control with CCTV so that entry attempts are recorded on camera. Others add intruder alarms so that any unauthorised access triggers an alert.
A layered approach like this gives you much better protection than any single system on its own.
What Happens During Installation?
A professional installer will visit your property, understand your needs, and recommend the right system. They will handle all fitting, testing, and set-up, and show you how to use everything before they leave.
