Access Control SoftwareDevelopment
Decide who can open which door and when, from one console, with a log of every entry and refusal.
Access Control Software Development: what the work involves
Physical access is a permissions problem. A new hire needs the office door and the server room does not, a contractor should expire on Friday, and a lost card must stop working immediately. Managing this controller by controller, or from a stack of keys, leaves gaps nobody notices until something goes missing.
We build access control software that sits above your door controllers and readers. People, groups, doors and time schedules are modelled in one place, and changes are pushed to the hardware. Every swipe, refusal and forced door is written to an event log, and alerts can be sent when something unusual happens, such as repeated failures on a restricted door.
Core features
People and credential registry
Each person holds one or more credentials such as cards, PIN codes or fingerprints, which can be issued, suspended or revoked from one screen.
Door groups and access levels
Doors are grouped into zones and linked to access levels, so granting a role means granting a set of doors rather than ticking each one.
Time schedules and holidays
Access can be limited to working hours, weekends excluded, with public-holiday overrides and temporary windows for contractors.
Event log and search
Every grant, denial, door-held-open and tamper signal is recorded with time and person, searchable by door, user or date range.
Real-time alerts
Forced entry, repeated denials and doors left open raise an alert to the security desk or by message, with the door and time attached.
Lockdown and emergency override
An authorised operator can lock or release a set of doors from the console, and the action is logged for later review.
What we get right before launch
Controller protocol and vendor lock-in
Door controllers speak vendor-specific protocols. We choose or build an adapter layer so the software is not tied to a single brand, and we state clearly which hardware we have tested.
Failing safe
If the server or network is down, doors must still follow a known rule. We keep schedules and credentials on the controller where supported, and agree fail-open or fail-secure behaviour per door with your safety requirements.
Revocation speed
A terminated employee's access should end the same hour. We link the registry to HR status where possible, so offboarding disables credentials without a second manual task.

Common questions, answered
Can you work with the door controllers we already have?
It depends on the controller. Many expose network or serial interfaces we can integrate with. We test against your actual models in discovery and tell you honestly if a device would need replacing to be managed centrally.
What happens during a power or network failure?
That is a design decision made per door. Controllers can keep stored credentials and schedules locally, and the log syncs when the network returns. Fire-safety doors follow your required fail-safe behaviour.
Can staff access be tied to the HR system?
Yes. Joiners, role changes and leavers from your HR or attendance records can drive credential issue and revocation, which removes the common gap where ex-staff cards keep working.
What influences the cost?
The count and brand of doors and controllers, number of sites, integrations such as HR or attendance, and the alerting and reporting you want. Hardware purchase is separate from the software scope.
