A key answers one question: does this person have a key? Access control answers three: who is this person, which doors are they allowed through, and at what times. For most Ottawa businesses — from a single-suite office to a multi-tenant building — that difference is the reason to make the switch. This guide is about how the systems actually work and what to think about when specifying one.

Credential types

Cards and fobs. The workhorses. A proximity card or key fob is tapped at a reader by the door. Cheap to issue, easy to carry, and instantly revocable. Modern encrypted formats cannot be cloned the way older 125 kHz cards could, so specify the encrypted type.

PIN keypads. A code instead of a credential. Useful as a backup or for low-security doors, but codes get shared, so we rarely use PIN alone on an exterior door. PIN plus card is a strong combination for a server room or cash office.

Mobile credentials. The phone becomes the key, over Bluetooth or NFC. Staff never forget it, issuing a credential is an email rather than a trip to the office, and revoking one is a click. Increasingly the default for new installs.

The access log

Every tap is recorded: who, which door, what time, granted or denied. That log is the quiet reason access control pays for itself. It settles the “who was in the stockroom Saturday night” question in seconds, it shows you when a credential is being used at odd hours, and it gives you a record for insurers and, if it ever comes to it, the police. Keys leave no trail at all.

Zones and schedules

Permissions are set by person and by door. Front-of-house staff get the front door during opening hours; the manager gets everything, all hours; the cleaner gets the front door between 9 p.m. and midnight on weekdays; the contractor gets the mechanical room for one week and then the credential expires on its own. Doors can also unlock on a schedule — the lobby open to the public 9 to 5, locked outside those hours — with no one turning a key.

Integration with cameras and the alarm

On its own, access control tells you a door opened. Tied into your cameras, a door event pulls up the video of who walked through it. Tied into the intrusion alarm, the system can disarm the alarm when the first authorised person badges in each morning, and flag a door that was forced or propped open. This is the same integration principle that runs through everything we install: one system, not three.

From one door to a whole building

The smallest system we install is a single reader on a suite door with a handful of fobs. The largest cover every exterior and interior door across a building, with elevator control and visitor management. The same architecture scales between them: a controller near each group of doors, readers and electric strikes or maglocks at the doors, and software you can manage from a browser or phone. Start with the doors that matter and add the rest as budget allows — nothing is wasted.

What to decide before you get a quote

Which doors need control, which people need which access, whether you want schedules, and whether the doors themselves are suitable (a glass storefront door and a steel back door need different hardware). A site visit sorts out the door hardware questions, which are the part most people cannot answer from a desk.

Next step

Access control is one layer of a complete commercial security system in Ottawa, alongside cameras, alarm and monitoring. If you are thinking about replacing keys on one door or fifty, call 613-627-0660 and we will walk the building with you and give you a written scope.
