Cloud access control · DuPage County
BTI Communications Group is a Brivo dealer and installer for DuPage County offices, campuses and plants in Naperville, Wheaton, Elmhurst, Oak Brook and Downers Grove. Our Chicagoland office is in Downers Grove, so DuPage sites get Brivo installation, support, renewals, account takeovers and Eagle Eye video from a team based in the county.

Local Brivo team
Brivo is a cloud access control platform. Doors, readers and controllers on site connect to Brivo Access in the cloud, so you manage users, schedules and lockdowns from a browser or the Brivo app instead of a server in a closet. Brivo and Eagle Eye Networks merged on December 29, 2025, so cloud video now runs on the same platform.
DuPage County is home base for our Chicagoland team. Corporate headquarters in Oak Brook, office parks along I-88 in Naperville and Lisle, and manufacturers in Addison, Itasca and Wood Dale use Brivo to run doors in several buildings from one account. Sites along I-88, I-355, I-290 and Roosevelt Road are often 5 to 25 miles from our Downers Grove office.
BTI has been in business for over 40 years and has delivered commercial security since the 2010s. 4-hour onsite emergency response is available under BTI support agreements.

Platform and hardware
Every Brivo system has three layers: the cloud platform, the controllers and readers at each door, and the credentials people carry. We quote each layer as its own line item.

Cloud access control run from any browser or the Brivo app: schedules, remote unlock, one touch lockdown, event logs and elevator control. Brivo Security Suite adds video, visitor management and intrusion in Standard, Professional, Enterprise and Multifamily editions.
Cloud access control explained
Mullion, single gang, keypad and recessed styles on OSDP or Wiegand. They read Brivo Mobile Key, Wallet badges, 13.56 MHz smart cards and 125 kHz prox, and HID readers that meet Brivo standards can stay.
Brivo readers and hardware
We size the panel to each building: the compact ACS300 for a handful of doors, the modular ACS6000 and current generation ACS6100 for larger buildings, the ACS-SDC single door controller for a suite, and Brivo Mercury Solutions to convert supported Mercury panels.
Compare Brivo controllers
Brivo renamed Mobile Pass to Brivo Mobile Key in October 2026, with no reissue needed. Staff open doors with a phone over Bluetooth or the cloud, or tap a badge in Apple Wallet or Google Wallet. Cards, fobs and phones are issued from one Brivo account.
Brivo mobile credentials
The Brivo Door Station combines a video intercom, a reader and a camera at the entrance, and staff open the door from the Brivo app. Brivo Visitor Management, powered by Envoy, issues guests a pass from the same system.
Door Station details
Schlage XE360 with RealSync, Allegion NDE and LE, ASSA ABLOY Aperio and dormakaba locks can join Brivo for interior doors. Supported Bosch B and G Series panels (now Radionix) and Alula communicators arm and disarm from Brivo, and single sign on with Microsoft Entra ID and Okta keeps users in sync.

Cameras and video
Since the merger, Eagle Eye cloud video is offered as Brivo Eagle Eye Video inside Brivo Security Suite. A badge event or forced door alarm opens the matching clip in the same Brivo account, so an investigation starts from the event instead of hours of footage.
More on recorders and licensing: Brivo Eagle Eye Cloud VMS.
Full lifecycle
One team covers the whole life of the system, from the first door survey to the next renewal. Field work is scheduled from our Downers Grove office at 630-343-1322.
Door by door survey, Brivo controller and reader installation, electrified locks, door contacts and request to exit, then testing each opening with your team in DuPage County.
Once you confirm ownership, we handle the dealer change with Brivo, then audit users, schedules and hardware so nothing breaks during the move.
We review door counts, Mobile Key credentials and Security Suite edition at each renewal so you pay for what you use, and renewals do not lapse.
Offline panels, failed readers, lock and power supply faults. Emergency support is available 24/7 at 800-435-7284, with 4-hour onsite emergency response under BTI support agreements.
Repair: we test offline doors, replace failed readers, locks and power supplies, and confirm each door reports to Brivo before we leave.
Move from an old server based system or end of life HID iCLASS SE and multiCLASS SE readers to Brivo and HID Signo, convert supported Mercury panels, and add OSDP readers and mobile credentials.
24/7 system health and alert monitoring is available, plus a 24/7 converged security NOC/SOC. Admins learn schedules, holidays, lockdowns and user changes before we close the job.
Buyer's guide
Most buyers ask the same questions before they sign. This is the order we answer them in.
List every door, gate, elevator and parking entry that needs a reader, plus the ones that only need a door contact.
The survey shows which strikes, mag locks and readers can be reused and which must be replaced.
Choose cards, fobs, Brivo Mobile Key or Wallet badges, or run cards and phones together while staff switch.
Decide whether Eagle Eye cameras, an existing VMS or a burglar alarm panel should report into Brivo.
Doors move in groups after hours so tenants and staff keep access during the cutover.
Admins get a written door schedule and hands on time in the Brivo portal and app before we close the job.
Cost and quotes
Brivo cost depends on the number of doors, the hardware already on site and the subscription you choose. We do not publish a price list, because two buildings with the same door count can need very different work. A written quote shows each item separately.
| Cost item | One time or recurring | What changes the number |
|---|---|---|
| Controllers and readers | One time | Door count, ACS300 vs ACS6100, reusing existing readers |
| Locks, power and cabling | One time | Door type, existing strikes and mag locks, cable paths |
| Brivo subscription | Recurring | Security Suite edition and number of doors |
| Mobile credentials | Recurring | Number of Brivo Mobile Key users |
| Eagle Eye video | One time and recurring | Cameras, Bridges or CMVRs, retention days |
| Support agreement | Recurring | Response time and monitoring you want |

24/7 system health and alert monitoring is available, plus a 24/7 converged security NOC/SOC that watches offline panels and alarms.

Government & public sector
BTI is a GSA Approved Contractor
GSA contract (all states) for business phone and security systems. CMAS and TESMA for California public agencies only. ISNetworld member contractor.
Doors and the law
Brivo keeps a cloud audit log of every door event and admin change, which helps when an auditor, insurer or landlord asks who entered and when. See converged security and IT compliance for the network side.
Each suburb enforces the IBC edition its village board adopted, and Chicago enforces its own building code. Electrified exit doors must open from inside without a key, with request to exit and fire alarm release where required. We confirm the rules with each village before install.
Under the 2010 ADA Standards, readers and buttons people must operate generally sit within the 15 to 48 inch reach range. We mount to that range unless the AHJ says otherwise.
Illinois licenses private alarm contractors under the Private Detective, Private Alarm, Private Security, Fingerprint Vendor, and Locksmith Act of 2004. BTI holds Illinois security license 127.001638.

Questions
BTI Communications Group designs, sells, installs and supports Brivo access control in DuPage County from our Downers Grove office, and takes over existing Brivo accounts. Call 630-343-1322 or request a quote online.
BTI is a Brivo dealer and reseller that also installs and supports what it sells. If you searched for a Brivo distributor, you most likely need a dealer who can quote, install and support the system, which is what we do.
It depends on door count, hardware you can reuse and the subscription you choose. One time costs cover controllers, readers, locks and cabling. Recurring costs cover the Brivo subscription, mobile credentials and any Eagle Eye video. We give a written, line item quote after a free door survey.
Brivo is sold as a recurring subscription based on your Security Suite edition, door count and mobile credentials. BTI reviews door counts and users before each renewal so you do not pay for doors or credentials you no longer use.
Yes. After you confirm you own the system, we arrange the dealer change with Brivo, review every user and schedule, and fix doors that show offline or forced.
Brivo ACS300, ACS6000 and ACS6100 controllers, the ACS-SDC single door controller and Brivo Mercury Solutions, plus Brivo Smart Readers in mullion, single gang, keypad and recessed styles. HID readers that meet Brivo standards can often stay.
Yes. Brivo renamed Mobile Pass to Brivo Mobile Key in October 2026. It is the same credential and app, so existing mobile credentials do not need to be reissued.
Staff open doors with a phone over Bluetooth, through the cloud, or by tapping a badge in Apple Wallet or Google Wallet at a compatible reader. Admins issue and revoke mobile credentials from the same account as cards and fobs, and cards can stay as a fallback.
Yes. The merger was announced December 29, 2025, and the combined company operates under the Brivo name. Eagle Eye video is offered as Brivo Eagle Eye Video within Brivo Security Suite.
Yes for the doors. Brivo panels keep making access decisions locally with the credentials they already hold, then sync events to the cloud when the connection returns. Eagle Eye Bridges and CMVRs buffer or record video during the outage.
Emergency support is available 24/7. Call 800-435-7284. 4-hour onsite emergency response is available under BTI support agreements, and 24/7 system health and alert monitoring is available through our converged security NOC/SOC.
Yes. We reuse strikes, door contacts and request to exit devices that test good, convert supported Mercury panels through Brivo Mercury Solutions, and replace end of life HID iCLASS SE and multiCLASS SE readers with HID Signo.
Call us or request a quote. We confirm your company owns the account, ask Brivo to move the account to BTI, and document your doors, users and subscriptions before any change, so nothing is deleted or cancelled during the handoff.
Yes. A badge event or forced door alarm opens the matching Eagle Eye clip in the same Brivo account. Many existing IP and ONVIF cameras can connect through an Eagle Eye Bridge or CMVR after we check models and bandwidth.
Yes. Most offline doors trace back to network, power supply, panel or reader faults. We test each one, replace failed parts and confirm the door reports to Brivo before we leave.
Not always. Many electrified locks, strikes, door contacts and request to exit devices can stay. The survey shows which openings can reuse hardware and which need new readers or locks.
With supported panels, yes. Brivo documents Bosch B and G Series panels (now sold under the Radionix brand) and Alula communicators, so staff can arm or disarm from Brivo or with a double swipe at a reader. We confirm your panel model first.
Often. Brivo lists OpenEye and Milestone XProtect alongside its own Eagle Eye video. If you record on another platform, we check what connection it supports before you commit.
Yes. Brivo supports wireless locks such as Schlage XE360 Series with RealSync, ASSA ABLOY Aperio and Allegion locks, so many interior doors join Brivo without new cable to each door.
Brivo Visitor Management, powered by Envoy, is part of Brivo Security Suite. A receptionist can issue a guest a mobile pass, PIN or QR code from the same system that runs the doors.
Our Downers Grove office sits in DuPage County. We cover Naperville, Wheaton, Downers Grove, Elmhurst, Lombard, Oak Brook, Addison, Glen Ellyn, Lisle and nearby towns, often 5 to 25 miles from the office.
Yes. We survey each door, reuse strikes, door contacts and request to exit devices that test good, and move doors to Brivo in groups after hours so staff keep access during the cutover.
BTI has been in business for over 40 years, serving Chicago since 1985, Los Angeles since 2001 and Phoenix since 2006, and has delivered commercial security since the 2010s.
