Access Control — Know Exactly Who Gets In

How access control actually works

At each controlled door there are a few parts working together: a reader (keypad, card, or fob), a controller that makes the decision, a locking device, and a request-to-exit and door-position sensor so the system knows when the door is used. Someone presents a credential, the controller checks it against your rules — is this person allowed, at this door, at this time — and either releases the lock or denies it and logs the attempt. Every event is recorded, which is the part keys can never do: you get an audit trail of who went where and when.

The locking device is where a lot of installs go wrong. A magnetic lock (mag lock) holds the door shut with an electromagnet and fails open when power drops — good for glass and code-sensitive egress, but it must be tied correctly to the fire alarm and exit hardware. An electric strike releases the existing latch and can fail secure or fail safe depending on the door's job. Picking the wrong one creates either a door that traps people or a door that pops open in a power blip. We spec the hardware to the specific door, the traffic, and the egress and ADA rules that apply to it.

Fobs, cards, keypads — and what to actually use

Keypads use a code — cheapest, no credential to hand out, but codes get shared and rarely changed. Cards and fobs are assigned to a person, so you can turn one off the moment they leave without touching anyone else's access; fobs are durable on a keyring, cards double as IDs.

Mobile credentials — a phone as the key — are increasingly common and convenient for offices with turnover. For higher-security doors, we combine methods: a fob plus a PIN, for example. Most buildings mix them — a keypad on a back door, fobs for staff, mobile for management — and we help you match the credential to each door instead of forcing one everywhere.

Cloud or on-prem, single door or whole building

Access control can run on a local controller in your building or through a cloud platform you manage from a browser or phone. Cloud is the practical choice for most clients now: you add or revoke a tenant or employee remotely, pull an audit trail from anywhere, and get software updates without a service call. On-prem still makes sense where a client wants everything to stay in the building or has no reliable internet.

We install both and tell you which fits your operation and budget rather than defaulting to whatever we stock.

For multi-tenant buildings — a common Queens and Bronx job — the value is management: each tenant gets their own credentials, the lobby and common doors are controlled, and property management can grant or cut access without a locksmith.

Tie the front door to a video intercom so tenants buzz guests in from their phones, and to video surveillance so a badged entry pulls up the door camera. It all rides on clean structured cabling, which is why we handle that in-house.
