Install, upgrade, or fix — pick your starting point
Three different situations, three different playbooks. Each one has its own detailed page.
New system installation
From one office door to a full multi-tenant building: survey, door hardware, controllers, readers, wiring, network, credentials, documentation. Designed so adding doors later doesn't mean starting over.
Installation in Chicago →
Legacy system upgrade
Old fob system with no audit trail, or a platform whose maker no longer exists? We keep the wiring and locks that test clean — typically 30-50% cheaper than rip-and-replace — and switch the building door by door.
Upgrades & retrofits →
Repair & takeover
Doors not locking, readers blinking, installer not answering? We fix any brand and take over orphaned systems: stabilize first, document everything, then talk about improvements — no pressure to replace what works.

Cloud or on-premises: the first decision
Short answer: most Chicago condos and property managers end up on Brivo cloud; single-site offices that want zero subscriptions and on-site data pick Paxton Net2. Here's the honest comparison we walk clients through:
| Brivo (cloud) | Paxton Net2 (on-premises) | |
|---|---|---|
| Managed from | Browser or phone, anywhere | Net2 software on your own server |
| Your data lives | Brivo cloud, encrypted | On-site, on your LAN |
| Recurring fees | Monthly subscription per account | None after purchase |
| Internet goes down | Doors keep working; controllers cache credentials | Doors keep working; nothing depends on the internet |
| Mobile credentials | Built in (Brivo Mobile Pass) | Via Paxton10 upgrade path |
| Best for | Condos, HOAs, multi-site portfolios, no on-site IT | Single-site offices, medical/legal, data-sensitive orgs |
Still on the fence? We wrote a full Brivo vs Paxton comparison for Chicago buildings, an honest look at the pros and cons of cloud access control — and for offices leaning cloud, a walkthrough of cloud access control for a Chicago office.

Built around your building, not a spec sheet
A 200-unit tower and a six-flat have nothing in common except doors. Staffing, resident turnover, vendor traffic, and existing wiring decide the design.
Condos & HOAs
Our specialtyMulti-tenant buildings, downtown and beyond
This is most of our work. Move-in fob enrollment that takes minutes, vendor access windows instead of loaned keys, audit logs the board can actually read, and elevator and garage access on the same credential. We've built it both ways — brand-new systems and upgrades that keep the old wiring, which is cheaper and faster when the cable tests clean.

Offices
Clear roles, clean handoff
Departments, shifts, and access levels; visitor and delivery handling; documented configuration your next office manager can pick up without calling us. Cloud admin for teams that aren't always on-site, Net2 for those who want everything in-house.
High-rises & mixed-use
Many entrances, one system
Lobby, garage levels, amenity floors, rooftop decks, service entrances — high-rise access lives or dies on network design and controller placement. We segment VLANs, budget PoE, and put controllers near remote doors instead of running 300-foot wires.
Warehouses & commercial
Shift schedules and loading docks
Time-zoned access for crews, gate and overhead-door control, and readers that survive forklifts and weather. Straightforward systems that a plant manager can run — see our warehouse & light industrial page.

How an install actually goes
A $3,000 controller is worthless if the door doesn't latch. So we start at the door and work backward — to UL 294-listed hardware, SIA OSDP reader wiring, ADA mounting heights, and Chicago egress code on every opening.
Step 1
Door-by-door survey
Frames, closers, strikes, latch alignment. The door hardware decides the lock — not the other way around.
Step 2
Power & wiring check
We test existing runs, supplies, and batteries. Whatever passes stays — that's where upgrade savings come from.
Step 3
Mount & terminate
Readers, locks, controllers — labeled panels, clean terminations, documented wire paths. No mystery cables for the next tech.
Step 4
Network & power backup
Own VLAN, PoE budget with headroom, UPS sized for the panel. Most "random" door failures are network failures.
Step 5
Handoff & training
Credential enrollment, admin training for your manager or board, and documentation you own — not us.
Recent access control work
Chicago, IL · 200+ unit condo tower
50+ cameras & unified access control for a Chicago tower
Standalone door controllers with no central database, a third of the cameras dead, daisy-chained consumer switches. Rebuilt in three phases over six weeks: UniFi network with VLANs, Hanwha cameras, and Brivo cloud access on every entry point from lobby to pool deck — with a parallel-run period so residents never had a hard cutover day.

North Shore, IL · Condo association
Condo access control upgrade — keeping the good wiring
An aging fob system upgraded to cloud management while reusing the cable runs and door hardware that tested clean — the door-by-door transition kept the building secured throughout, and the board got audit logs for the first time.
Read the case study →
Doors don't work alone
We design access control together with the systems around it — one credential, one network, one installer to call.
Security cameras
Door events linked to Hanwha and Axis camera footage — every entry gets video evidence.
Video intercoms
2N and ButterflyMX panels share credentials with the door system — one fob or app for both.
Network infrastructure
Ubiquiti UniFi switching with VLAN segmentation — access traffic isolated from lobby Wi-Fi, always.
From the owner
“Most access control failures I get called to aren't the hardware. They're power, wiring, and network shortcuts somebody took on install day. We don't take them — that's the whole trick.”

Questions boards and managers actually ask
How much does an access control system cost in Chicago?
Hardware is priced at manufacturer MSRP right on this site: a Brivo ACS300 controller is $1,265, a Smart Reader is $349, a 25-pack of encrypted fobs is $234. Installation labor depends on door count, wiring condition, and lock hardware — we quote it after a free survey. Full breakdown: what access control costs in Chicago.
What is the best access control system for a condo building in Chicago?
For most Chicago condo and HOA buildings we recommend Brivo cloud access control: the board and property manager handle move-ins, move-outs, and vendor access from a browser, with a full audit trail and no server to maintain. Buildings that want zero subscriptions or on-site data pick Paxton Net2 instead — the comparison article walks through the trade-offs.
Do you repair or take over systems you didn't install?
Yes — a large share of our service calls are systems whose installer closed or stopped answering the phone. We troubleshoot any brand, recover or rebuild admin access, document the wiring, and support the system going forward. Details on the repair & support page and system takeover.
Can you reuse existing wiring and locks when upgrading?
Usually yes, and it's the cheaper, faster path. We test every cable run, strike, and maglock during the survey; whatever passes stays and gets connected to new controllers. That typically cuts an upgrade cost by 30-50% versus rip-and-replace, and the building switches door by door without losing coverage — see how our upgrades work.
Can you integrate access control with elevators and garage gates?
Yes. We wire elevator floor control, garage gates, and overhead doors into the same credential system, using documented relay interfaces and coordinating with the elevator or gate vendor when needed. One fob or phone handles the front door, the elevator, and the garage — including windshield tag readers for parking.
Will doors unlock during a power outage?
Depends on the lock: magnetic locks are fail-safe (power lost, door releases), electric strikes can be fail-secure and stay latched. Egress code decides which is legal on each door. We select hardware to meet Chicago life-safety requirements and add UPS backup so a blink in the power doesn't become an open building.
Key fobs or mobile credentials — which should our building use?
Run both. Modern readers accept encrypted fobs and phone credentials side by side, so residents who want an app use Brivo Mobile Pass while everyone else keeps a fob on the keychain. Encrypted DESFire EV3 fobs don't clone at a kiosk the way old 125 kHz prox fobs do.
What access control brands do you install in Chicago?
Primary platforms: Brivo (cloud) and Paxton Net2 (on-premises), plus HID Global readers, 2N intercoms, and Schlage/Accentra locks. We repair systems from Honeywell, LenelS2, Genetec, and others.
