Doors as part of your security posture
Most businesses treat physical access and network security as unrelated problems handled by different vendors. In practice they are two halves of the same question, which is who is allowed to reach what.
An access control system answers it for the physical layer, and it does so with something keys can never provide: a record. Every entry, every denial, every door propped open, timestamped and retained. When something happens, that record is what turns speculation into fact.
Credentials
Mobile. A credential held in the phone people already carry and never forget. Issued and revoked remotely, so a new hire is granted access before their first day and a departure is handled from anywhere in seconds. Cryptographically far stronger than legacy cards.
Smart cards. Encrypted contactless cards for visitors, contractors and staff who prefer a badge. Modern encrypted formats, not the older proximity technology.
A note on legacy cards. The 125 kHz proximity cards still in wide use can be cloned with cheap, readily available equipment by anyone who gets within a few inches of one. If that generation of credential is currently protecting anything you care about, replacing it is a genuine security improvement rather than a sales pitch.
Designing the policy, not just the hardware
The hardware is straightforward. The value comes from getting the access policy right.
We work through who needs to reach which spaces at which times. Cleaning crews get after hours access to common areas and not to server rooms. Contractors get credentials that expire on a date. Executives get everything. Delivery entrances unlock during receiving hours and lock automatically outside them. Holiday calendars apply without anyone having to remember.
For higher security environments we add anti passback so a credential cannot be handed back through a door, mantrap configurations where two doors must not be open simultaneously, and elevator control limiting which floors a credential can select.
Video, integrated
Access control and cameras on separate systems means an incident involves pulling a badge log from one platform, working out a timestamp and then scrubbing footage in another. On an integrated platform the badge event links directly to the footage of that moment.
We deploy IP camera systems with resolution and placement chosen for what you actually need to see. Identifying a face at an entry requires meaningfully different specification than watching general activity across a parking lot, and cameras placed to look impressive frequently fail to produce usable evidence.
Retention gets sized to your requirements and any regulatory obligation, with storage specified accordingly. Remote viewing works from anywhere, secured properly rather than through the exposed port arrangements that make so many camera systems a liability of their own.
Code, safety and the things that go wrong
Egress is not negotiable. Doors in the path of exit must permit exit without a credential and must release on fire alarm. We install code compliant hardware, coordinate with your fire alarm contractor and work with the local authority having jurisdiction. This gets done correctly or it does not get done.
We also plan for failure modes. Fail secure and fail safe are deliberate choices per door depending on what is behind it and what the code requires. Battery backup keeps the system running through a power outage. Door position and request to exit sensors are installed properly so the system knows the actual state of the door rather than inferring it.
Installation and management
Access control is low voltage work, and the cabling determines reliability. We run it as part of our structured cabling practice, with proper pathways, correct conductor specifications for lock hardware and clean terminations at the controller.
Because the system lives on your network, it belongs inside your network security design, on a segmented VLAN rather than sharing a subnet with staff workstations. Camera systems in particular are a common weak point when deployed carelessly.
Ongoing management can sit with your team or with us. Under a managed agreement we handle credential issuance and revocation, schedule changes, firmware updates and periodic reviews of who has access to what, which is a check almost nobody performs on their own and which reliably turns up credentials belonging to people who left two years ago.
