Access Control Systems for Doors, Offices and Estates
We design and install access control systems in Nairobi and across Kenya for offices, apartments, schools and industrial sites. Staff open doors with cards, PIN codes or phones, every entry is logged, and doors release safely during a fire or power failure.
- Cards, PIN, mobile or fingerprint credentials
- Fail-safe door hardware and fire alarm release
- Battery backup so doors behave predictably in outages
Keys are hard to control, which is why more owners now ask us about access control systems in Nairobi. People copy them, lose them and forget to return them when they leave. An electronic system fixes that. You decide who can open each door and at what times, and you can remove access in seconds. This page explains how access control systems in Nairobi work, what hardware we use and the details that keep doors safe.
Access control
How access control systems work
Every door in a system has the same four parts. Understanding them makes quotes much easier to compare.
| Part | What it does | Where it sits |
|---|---|---|
| Reader | Reads the card, PIN, phone or fingerprint | Beside the door, at a comfortable height |
| Controller | Decides whether this person may enter now | In a secure cabinet, often in a ceiling or comms room |
| Lock | Holds the door shut and releases it | On the door frame or in the door |
| Software | Manages users, schedules and reports | On a PC, server or cloud portal |
When a staff member presents a card, the reader passes the number to the controller. The controller checks the user's rights and, if they match, releases the lock for a few seconds. Meanwhile, it records the event with a time and door name. On the way out, staff press an exit button or use a second reader.

Credential options: cards, PIN, mobile and biometric
The credential is what a person carries or knows. Each option has trade-offs.
- RFID cards and tags: cheap, fast and easy to cancel. However, people can lend them to others.
- PIN codes: nothing to carry, but codes get shared and keypads wear out.
- Mobile credentials: the phone becomes the key, which suits modern offices with visitors.
- Fingerprint and face: the person is the key, so sharing is impossible. Our biometric attendance systems page explains these readers.
Many access control systems in Nairobi combine two options. For example, server rooms often need a card plus a PIN, while the main entrance only needs a card.
Access control
Door hardware: magnetic locks, strikes and exit buttons
The lock matters as much as the reader. If the hardware is wrong for the door, the system will fail no matter how good the software is.
We check the frame, the door and the way people use it before choosing hardware. In practice, a heavy steel gate needs a very different lock from an internal office door.
Access control
Access control systems for offices, apartments, schools and industrial sites
Different sites need different rules. Here is what we usually set up.
| Site | Typical doors | Common rules |
|---|---|---|
| Office | Main entrance, server room, finance, stores | Office hours only, managers anytime |
| Apartment block | Pedestrian gate, lobby, gym, rooftop | Residents only, cleaners by schedule |
| School | Staff room, labs, stores, dormitories | Staff by role, night locks |
| Factory or warehouse | Stores, offices, production areas | By shift and department |
For vehicle gates, we pair readers with boom barriers for vehicle access control. At visitor points, a video intercom lets reception see and speak to callers first.
Access control
Access reports, user groups and visitor handling
Good software saves your administrator time, and it is where access control systems in Nairobi differ most between brands. We set up user groups such as staff, managers, cleaners and contractors, each with its own doors and hours. As a result, adding a new employee takes a minute.
Reports show who entered which door and when. They also show refused attempts, which often point to a lost card or someone testing a door. You can export them for investigations or for HR. For visitors, we can issue temporary cards that expire at the end of the day, or a QR code sent to the visitor's phone.
Fire safety
Power backup and fire alarm release
This is the point most quotes skip, and it is where systems fail in real life.
First, every controller and lock power supply needs a battery or a UPS power backup. Without it, a power cut either locks people in or leaves every door open, depending on the lock type. We decide the right behaviour for each door with you.
Second, escape doors must release when the fire alarm sounds. We wire a fire alarm input to the access controllers, so all escape routes open automatically. In addition, a green break-glass unit gives a manual release at each door. This link matters for safety and for any fire inspection. Our fire alarm installation team can supply the alarm side if needed.
Fail-safe or fail-secure?
A fail-safe lock opens when power is lost, which suits escape routes. A fail-secure lock stays locked, which suits stores and cash rooms that are not escape routes. Getting this right on every door is part of designing access control systems in Nairobi properly.
CCTV
Linking access control with CCTV
When cameras and doors work together, investigations get faster. A forced door can trigger a camera alert, and each access event can link to the recording from the camera above that door. Our CCTV installation service plans camera views around your access points for exactly this reason.
Costs and pricing
Access control systems cost factors in Nairobi
As a guide, a single standalone door with a card reader, maglock, exit button and backup power often starts from about KSh 35,000 installed. Networked systems with several doors are priced per door after a survey. Our article on planning office access control has more help, and the price guide compares costs across systems.
Rules and standards
Standards and good practice we follow
We follow the manufacturer's installation guides and sound electrical practice. Escape doors must stay usable during an emergency, which is a basic requirement of fire safety law in Kenya. We also protect personal data in the access logs, because names and entry times are personal information. The Office of the Data Protection Commissioner explains the duties of anyone who collects this kind of data.
Other good habits we build in:
- Cable protection: we run reader and lock cables inside the secure side of the wall, so nobody can bypass a door from outside.
- Clear labels: each controller port and door name matches the drawings we hand over.
- Tamper alerts: controllers sit in locked boxes with tamper switches where the risk is high.
- Regular tests: we show your team how to test exit buttons and fire release every month.

Frequently asked questions
How much does an access control system cost per door?
A standalone door with a card reader, magnetic lock, exit button and power backup often starts from about KSh 35,000 installed. Networked doors with software cost more per door but save time on larger sites. The lock type, cable distance and credential type move the price most. We give an itemised quote after a survey.
Card, PIN or biometric: which should I choose?
Cards suit most offices because they are quick and easy to cancel. PIN codes work for small teams but get shared. Fingerprint or face readers stop people lending credentials, so they suit server rooms, stores and attendance tracking. Many sites mix them, for example cards at the entrance and fingerprint at the server room.
What happens to the doors if power fails?
That depends on the lock and the backup. With a battery or UPS, doors keep working normally through an outage. When the backup finally runs out, fail-safe locks open and fail-secure locks stay shut. We agree the right behaviour for each door during the design, so nobody gets trapped.
Can access control link to my fire alarm?
Yes, and on escape routes it should. We connect a fire alarm output to the door controllers so escape doors release when the alarm sounds. Each door also gets a green break-glass for manual release. This keeps exit routes open in an emergency while doors stay secure the rest of the time.
