BTI Communications Group does a solid job. From the proposal process straight through to job completion and subsequent support, everyone does exactly what they say they will. We had a solution installed at one location as a test of sorts. Based on the success of that, we are now getting ready to install at a third location.

ACCESS CONTROL INSTALLATION CHICAGO

Get the Access Control
Help You Need Now

Whether you are installing a new system, upgrading what you already have, changing providers, or expanding to additional facilities, BTI supports both cloud-managed and on-premises access control platforms and can support the project from initial planning through ongoing service.

Access Control System Installation

Get a smoother installation with fewer surprises, better documentation, and built-in testing and quality control from the start, making handoff and future support easier for your team.

Access Control Programming & Commissioning

Start with the system configured, tested, and ready for daily use, so your team spends less time correcting setup issues after handoff.

Access Control Troubleshooting & Repair

Resolve access problems faster with structured support and field escalation that help restore normal operation with less disruption. 

User, Badge & Credential Management

Make employee access changes easier by simplifying how credentials are added, updated, or removed as roles and responsibilities change.

Access Control Maintenance & Managed Support

Keep your system more reliable with ongoing monitoring, updates, and support that helps catch issues before they become bigger problems.

Access Control System Takeovers & Remediation

Change providers without starting over. BTI can help stabilize the existing system, improve documentation, and create a clearer path forward.

Multi-Site Access Control Deployment

Keep projects more consistent across locations with coordinated installation, testing, documentation, and support from site to site.

COMMERCIAL DOOR & ENTRY APPLICATIONS

Access Control for More Than Standard Office Doors

BTI designs access control around the actual opening, traffic patterns, security requirements, and operating conditions, not just the reader on the wall.

avigilon access control openpath reader

Specialized Openings

Plan around existing door hardware, locking requirements, life-safety considerations, and unusual physical conditions.

Gates & Perimeter Entry

Control vehicle and personnel access at exterior entry points.

Warehouse & Overhead Doors

Secure high-traffic operational openings while accounting for how those areas are used.

Restricted & High-Security Areas

Apply stronger access controls where sensitive assets, information, or operations require tighter restrictions. 

The BTI Difference

More Than an Access Control Installer in Chicago

Get more accountability, clearer ownership, and better follow-through from a partner built to stay engaged beyond the initial installation.

One Accountable Partner

Simplify ownership across the project with one team coordinating access control and the surrounding technology, so responsibilities stay clearer from start to finish.

Agnostic by Design 

Get the platform that fits your business, not the one an installer is tied to. BTI supports multiple commercial access control systems, giving you more choice and less vendor lock-in.

Better Project Visibility

Know what is happening throughout the project with structured coordination, documentation, and follow-through instead of having to chase status yourself.

Stronger Quality Control

Get more confidence at handoff with testing, documentation, and QA built into BTI’s project process rather than treated as an afterthought.

Support Beyond the Installation

Keep continuity after the project with a team that can support changes, troubleshooting, upgrades, and future expansion as your environment evolves.

Built for Multi-Site Organizations

Keep projects and standards more consistent as you add facilities, with centralized project coordination and a delivery model designed for distributed environments.

CENTRALIZED ACCESS MANAGEMENT

Make Access Easier to Manage

Make day-to-day access control simpler as employees, roles, doors, and locations change, while giving your team clearer visibility into access activity and keeping the system better connected to the rest of your security environment.

Change access without changing locks

Remove credentials quickly when employees leave

Keep permissions consistent as roles change

Review access activity and audit trails when questions arise

Manage multiple doors and locations from a more centralized system

Connect access control with cameras, alarms, visitor management, and other supported systems

How It Works

A More Predictable Access Control Project

BTI uses a structured process to surface issues early, define the right scope, verify the installation, and leave your team with a cleaner handoff.

 

Step 01

Assess the Site and Requirements

BTI reviews the facility, individual openings, existing hardware, wiring, power, network dependencies, current systems, and operational requirements to understand what can stay, what needs to change, and where problems may arise.

Step 02

Build the Right Plan

BTI defines the recommended system, integrations, upgrades, retained equipment, project requirements, and implementation approach, so your team understands what is being done and why.

Step 03

Install, Test & Verify

BTI coordinates installation and programming, then completes testing, punch-list resolution, and quality-control checks before the project is closed.

Step 04

Document and Support the Environment

BTI provides relevant closeout documentation like system documentation, device information, and closeout materials instead of being left to reconstruct the project later. 

Step 05

Support, Renew, and Expand Your Network

BTI can remain involved in troubleshooting, credential changes, upgrades, new doors, and future locations.
