Access Control Systems in Rwanda

What is an access control system, and who needs it

It’s a set of controlled doors, each with a reader for cards, PINs or biometrics, an electric lock, a door sensor and an exit button, wired to a controller and managed through software. Permissions are set per person and area, and every event is logged. It suits offices with server rooms or finance areas, clinics with pharmacies and records rooms, schools, warehouses and stores, and any site where keys have been copied, lent or never returned.

The problem it solves

A key tells you only that a door was unlocked, not who opened it. Keys get copied and lent, and a lost key means changing the lock. Access control ties every entry to an individual credential, limits each person to the areas they need, and keeps a log that answers “who was in the store room last night?” with a name and a time rather than a guess.

The parts of a controlled door

Reader. Card, PIN, fingerprint or face, chosen per door by how strictly entry must be tied to one person.

Lock. Electric strike, electromagnetic lock or motorised lock, chosen for the door’s construction and whether it must fail safe or fail secure.

Door sensor and exit button. The sensor detects a door forced or held open; the exit button or handle lets people leave freely.

Controller. Makes the access decision and keeps working if the network or server goes down.

Power supply with battery backup, so doors behave as designed during a power cut.

Reader wiring. Older readers use the Wiegand protocol, which sends credential data unencrypted and can be intercepted. Newer systems use OSDP, the Open Supervised Device Protocol, now an IEC standard, which supports encryption and alerts if a reader is tampered with. For new installations we specify OSDP with its secure channel switched on wherever the readers and controllers support it.

What the work involves

1. Survey the doors: construction, frames, hinges, fire rating, power and cabling routes.
2. Map areas and access levels with you, and decide each door’s lock type and power-failure behaviour.
3. Install readers, locks, sensors, exit buttons, controllers and power supplies.
4. Configure the software, areas, schedules and alarms for forced or held-open doors.
5. Enrol credentials, issuing cards or registering PINs and biometrics.
6. Test every door, including power failure and fire alarm behaviour, then hand over the door schedule.

What’s included and what’s not

Typical timelines and what drives cost

A handful of controlled doors typically takes one to three days to install, after a survey. Cost is driven by the number of doors, the reader type at each, the lock hardware each door’s construction requires, cable runs back to the controllers, fire and egress requirements, and whether doors need glass, metal or gate-specific hardware.

Equipment typically used

Card and PIN readers, fingerprint and face readers where identity matters, electric strikes and electromagnetic locks, door contacts, exit buttons and emergency break-glass releases, networked door controllers, power supplies with batteries, and access control software. Where possible, readers and controllers that support OSDP and integrate with ONVIF-compatible video systems.

Common mistakes we see

Server rooms and stores left on keys while the main door gets a card reader. Permissions granted broadly “to be safe”. Cards not disabled when staff leave. Magnetic locks on escape routes without a proper release. No battery backup, so doors lock or unlock unpredictably in a power cut. Logs that nobody reviews. And clocks not synchronised with CCTV, so events can’t be matched to footage.
