What it is

Control every door from one system.

Access control replaces keys with credentials you can issue, change, and revoke in seconds, and records every door event.

The problem

Lost keys, former employees, and doors propped open. Rekeying is slow and you cannot see who went where.

What it does

Readers check a credential, the controller decides, and the lock releases. Schedules lock and unlock doors automatically.

What you manage

Users, schedules, and access levels from one screen. We can make changes remotely for most systems we support.

Five layers

Everything behind one door.

Security runs on power, pathway, cabling, and a network. We can install every layer, so nothing falls between contractors.

Cutaway of a door and the telecom room behind it: the lock power supply, the cable tray in the ceiling, the network switch, the reader, lock, and intercom at the door, and the access control server.

Questions

Access Control FAQ.

Short answers to the questions we hear most.

Can you add users or change door schedules remotely?

Yes, for most access control systems we support.

My door will not lock or unlock. Is that the lock or the system?

Usually the hardware: strikes, maglocks, crash bars, or door contacts.

Can lockdown, intercom, and fire alarm work with our door system?

Yes.

Cloud or on-premises?

Both. We recommend based on the site, the network, and your retention needs.

Can you take over a system another company installed?

Yes. Complex has completed 125+ platform conversions.
