BTI Communications Group, LTD. is a commercial security integrator with offices in Santa Fe Springs, Downers Grove and Phoenix, in business for over 40 years. We design, install and support office access control for lobbies, suites, elevators, parking and server rooms, on Brivo, Avigilon, Kantech, RS2 (Acre) or Axis, with mobile, card or fob credentials.

Requirements
Recommended setup
A typical office design pairs a cloud or owned platform with readers and electrified hardware sized to each opening.
Perimeter entries, lobby, suite doors, IT and server rooms, mail and supply rooms, and parking entrances, each with its own schedule.
Mobile credentials on employee phones, with HID cards or fobs for anyone who prefers them, managed from one roster.
Mullion and wall readers that read mobile and card credentials, with keypads added where two-factor entry is required.
Electric strikes, electrified exit devices and maglocks matched to the door, frame and local code review.
Front desk or kiosk check-in, printed or mobile visitor passes, and Axis network intercoms at unattended entries.
Door events tied to Axis or Avigilon video, or Eagle Eye cloud video (part of Brivo), so a forced door shows the clip.
User provisioning from your HR or identity directory, elevator controls and alarm arming by schedule.
Office buildings mix public and private space on every floor. BTI maps each opening before choosing hardware: the lobby that stays open from 7 to 6, the suites that only their staff should enter, and shared rooms such as conference centers, fitness rooms and mail rooms that need their own schedules.
Suite doors usually get readers with local schedules so a department manager can grant a contractor access for one afternoon without touching the rest of the building. Common areas get group permissions, and server and network rooms get a tighter rule set with a second factor and an alert on every forced or propped door. That design keeps the front desk out of routine badge changes and keeps an audit trail for the doors that matter most.

After hours, the risk moves to the elevator and the garage. BTI ties access control into elevator destination or floor-select controls so a badge only lights the floors its holder may visit, and stairwell doors lock from the stair side while staying free for egress.
Parking entrances, gates and garage pedestrian doors run on the same roster, so one credential covers the drive-in and the walk to the elevator. Holiday calendars, early-close days and emergency unlock schedules are set once and pushed to every door on the platform.
Many offices already have readers on the wall and a system nobody fully understands. BTI documents what is installed, tests each door and tells you what can stay, what needs a gateway and what should be replaced. BTI takes over Brivo, Kantech, Avigilon and RS2 (Acre) systems, so you can change integrators without ripping out working hardware.
Platforms
BTI is platform agnostic and recommends the platform after the survey. HID readers and mobile credentials work across most of them. Not sure which fits? Read the commercial access control guide.
Cloud access control with web and mobile administration. Eagle Eye cloud video is part of Brivo.
Brivo access controlCloud managed doors with touchless mobile entry and remote unlock.
Avigilon Alta access controlOn-premises access control that runs alongside Avigilon video on servers you own.
Avigilon Unity access controlEntraPass software and KT controllers for owned, scalable systems.
Kantech access controlAccess It! software for larger, multi-site estates that want an owned platform.
RS2 access controlAxis door controllers, readers and network intercoms that tie straight into Axis video.
Axis access controlInstallation
Office projects are often phased around move-ins and tenant improvements.
Office access control is quoted from a door-by-door survey. What moves the number: how many openings, the door and frame types, whether cabling exists, the platform and its licensing, elevator integration and how many sites share one system. Every line is itemized in the proposal.

Proof
BTI Communications Group, LTD. designs, installs and supports office access control from offices in Santa Fe Springs, Downers Grove and Phoenix, covering lobbies, suites, elevators, parking and server rooms on Brivo, Avigilon Alta (formerly Openpath), Avigilon Unity, Kantech, RS2 (Acre) and Axis.
It depends on how you want to manage it. Cloud platforms such as Brivo and Avigilon Alta suit offices that want remote administration and mobile credentials. Owned platforms such as Kantech, RS2 (Acre) and Avigilon Unity suit IT teams that want servers and data in house. BTI recommends a platform after a door survey.
Yes. Brivo, Avigilon Alta and HID mobile credentials let staff unlock doors with a phone, while cards or fobs stay available as a backup for anyone who wants one.
Yes. BTI designs, sells, installs, supports and takes over existing Brivo accounts, and also takes over Kantech, Avigilon and RS2 (Acre) systems without replacing hardware that still works.
Cost depends on the number of doors, door hardware, cabling, platform licensing and integrations such as elevators. BTI provides an itemized proposal after a free site survey.
Yes. BTI links door events to Axis, Avigilon or Eagle Eye video, which is part of Brivo, and connects visitor management and Axis network intercoms so the front desk sees who is at the door.
