Start with the doors, then choose the technology

The card reader is the visible part of the system. Reliable access also depends on the lock, closer, door alignment, power, wiring and the way people leave the building. A reader cannot correct a door that does not latch after someone walks through it.

For each opening, we want to understand who uses it, when it should be locked, who can change its schedule and what should happen if it stays open. A useful door plan includes:

• Public entrances: Should the lobby unlock on a schedule, or remain locked until an authorized employee arrives? What changes on holidays or a weather closure?
• Employee and service entrances: Which shifts, cleaners and delivery personnel need access? A contractor working for two weeks should not automatically receive permanent permissions.
• Interior doors: Decide whether stockrooms, records rooms, mechanical spaces or individual tenant areas need different access groups.
• Door condition and surroundings: Glass storefronts, older frames and fire-rated openings can require different hardware. Exterior readers and locking equipment must suit the exposure at that location.
• Exit operation: Review the opening as a complete assembly, including accessibility, required exit hardware and any necessary fire alarm interface.

For an older commercial building, a difficult cable route may matter more to the installation budget than the reader itself. In a multi-tenant property, the larger challenge may be assigning responsibility: the building manager controls the common entrance while tenants manage only the people and doors within their authority.

Cards, fobs, mobile credentials or PINs?

The best credential is one your staff can use consistently and your administrator can manage confidently. The reader, credential and controller must support the same technology; similar-looking fobs are not necessarily interchangeable.

A mobile credential used at a reader and an app command that unlocks a door remotely are different functions. Ask to see both if you need both, including what works when the phone or building loses connectivity.

Credential security and reader wiring are separate considerations. For a new installation or substantial upgrade, ask about OSDP reader communication with Secure Channel enabled. It can protect communication between compatible readers and controllers and supervise the connection. An OSDP label alone does not establish that encrypted communication has been configured.

Sicunet, Brivo and Alarm.com access control

We work with three access control platforms so the recommendation can account for your building, existing equipment and preferred way of managing users.

The comparison should include recurring software and credential costs, administrator permissions, event-history needs and the process for adding another building. We will explain the proposed configuration rather than assume every feature advertised for a platform is included.

Make the opening and closing routine work

Door access and intrusion alarm control are different permissions. For example, a cleaner may be allowed through an entrance without being allowed into a separately armed stockroom. If the systems are integrated, decide explicitly which credential action may disarm which area. A door timetable should not be assumed to apply to every connected alarm partition or smart lock.

Also decide who receives a door-held-open alert and what they should do with it. An alert that goes to an unattended inbox will not solve a delivery door that is routinely propped open.

Access history helps explain when credentials were used. It is not, by itself, proof of who physically entered or a complete list of people still inside. Shared credentials and people following someone through a door can leave gaps. Appropriately positioned security cameras can add context when reviewing an incident.

Can Cunningham take over an existing access control system?

Yes. We take over Sicunet, Brivo and Alarm.com systems, as well as older nonproprietary systems, including suitable Linear, DSC MAXSYS and DMP installations. The equipment at your property determines what can stay, what needs updating and which functions can be supported.

A takeover is not automatically a full replacement. It also should not be a promise to keep every component before the system has been inspected. We separate the evaluation into three parts:

1. Doors and field equipment: Check the locks, readers, door contacts, exit devices, wiring and power supplies for condition and compatibility.
2. Controllers and administration: Identify models, software or cloud accounts, available administrative access, current support and the ability to obtain replacement parts.
3. People and permissions: Review existing credentials, schedules and administrator roles, then plan the transfer so staff know how to get in and who to call.

Sometimes the sensible upgrade is a new controller with usable wiring and door hardware retained. In other cases, preserving an old reader or credential format would limit the security or features you are trying to gain. We will make those tradeoffs visible in the scope.

Plan the transfer of administration as carefully as the hardware. Agree who controls the account and recovery contact, how existing users and schedules will be checked, and when former administrators lose access. Test representative credentials before retiring the old management arrangement.

If you also want to move the building's alarm monitoring, see our alarm system takeover service. Access control administration and intrusion monitoring are related services, but they need their own compatibility review.

Plan for internet outages, power failures and safe exits

A network outage and a power failure are different events. Some controllers retain permissions and make local access decisions while the internet is unavailable; remote commands, newly changed permissions or cloud reporting may be affected. The proposed equipment and credential method determine the actual behavior.

Power planning must cover the controller and the equipment it operates, including locking hardware. We also review the intended operation when backup power is depleted. Do not assume that every electronic lock should behave the same way during a failure or a fire alarm.

For workplaces, OSHA's exit-route requirements generally require occupants to be able to open exit-route doors from inside without a key, tool or special knowledge. The specific locking arrangement also needs review under the building, fire and accessibility requirements that apply to the property. We coordinate the design and any required approvals with the appropriate project team and local officials.

Before handover: Test ordinary entry and exit, a revoked credential, an out-of-hours attempt, the holiday schedule and the documented outage behavior. Your administrator should also know how to add a user, remove one and recover access to the management account.

What affects the cost of commercial access control?

Door count is a starting point, not a complete price. Retrofitting an entrance with suitable existing electrified hardware is a different job from converting an older door with a difficult cable route.

• Door and frame condition, lock selection and any required repairs or preparation.
• Controllers, readers, credentials, cabling, power supplies and backup power.
• Network coordination, integrations, programming and administrator training.
• Any applicable permits, plan review and coordination with other trades.
• Ongoing software, mobile credential and service costs for the selected arrangement.

Tell us which doors matter first and what you expect to add later. That lets us compare a phased installation with a larger initial project without building in avoidable replacement work.
