We install, upgrade, repair, and maintain security systems across the city — IP and CCTV cameras, door access, intercoms, and the networking that keeps it all running. Built for property managers, HOA boards, and business owners who need fewer surprises and less downtime.
New installations, upgrades from legacy systems, repair, and scheduled maintenance of what's already on the wall.

Ubiquiti UniFi switches, access points, and VLAN design that keeps security devices stable and isolated.
Starting from scratch, replacing an outdated system, fixing something that quit, or keeping a working system healthy — all of it, across Chicago.
Complete security system design and installation — from a single entry door to a 200-camera building. Every project includes a site survey, equipment selection, professional wiring, network integration, and full documentation. We design for real-world reliability, not spec-sheet numbers.
Many Chicago buildings run outdated equipment — analog cameras, standalone fob systems with no audit trail, or platforms from companies that no longer exist. We upgrade to modern Hanwha, Brivo, and Paxton systems while reusing existing wiring and hardware whenever possible, saving 30-50% vs full replacement.
Cameras offline? Door not locking? NVR not recording? We diagnose and fix camera, access control, and intercom problems across Chicago — our installs or somebody else's, Aiphone buzzers included. We stabilize first, then talk improvements. Scheduled CCTV maintenance plans keep the ones that work working.
Chicago's commercial buildings face a unique combination of challenges: vintage construction with thick masonry walls and aging wiring, extreme weather swings from lake-effect cold to summer humidity, high tenant turnover in condos and offices, and the constant pressure of keeping common areas, parking garages, and loading docks secure. A security system that works on paper but fails in a February power outage or a flooded underground garage is worse than no system at all.
At Vidimost, we design and install security systems that account for these real-world conditions. Four years in business in Chicago, installers who've been pulling cable for over a decade, licensed and insured — and we've been inside enough buildings between the Loop and Rogers Park to know which walls fight back.
Most security companies sell equipment and install it. We start from the infrastructure — power, cabling, network, and door hardware — because that's where most system failures actually originate. A Hanwha Vision camera is excellent hardware, but it's useless if it's on an overloaded PoE switch with no UPS. A Brivo access controller is powerful, but not if the low-voltage wiring to the door lock has been spliced three times over 20 years.
Every project we take on — new installation, upgrade, or repair — includes an assessment of the full chain: power delivery, cable condition, network topology, and physical hardware condition. We fix the infrastructure problems as part of the project, not as a separate billable surprise.
Many Chicago buildings delay security upgrades because they assume everything needs to be ripped out. That's rarely true. Our upgrade process starts with an infrastructure audit — we test every cable run, check every lock mechanism, verify every power supply. If the existing wiring is Cat5e or better and tests clean, we keep it. If the existing cameras have usable mounting locations, we reuse the infrastructure.
We regularly upgrade buildings from analog CCTV to modern IP security cameras (Hanwha Vision, Axis), from standalone key fob systems to managed access control (Brivo or Paxton), and from buzzer-based entry systems to video intercoms (2N). The transition is phased door-by-door and camera-by-camera, so the building never loses security coverage during the process.
Some of our best client relationships started with a repair call. A parking garage camera that went dark. An access control system where fobs stopped working after a power surge. An NVR that's been "full" for months and nobody noticed it stopped recording. We troubleshoot and repair security systems across Chicago regardless of who installed them or what brand they are.
Common problems we fix: failed power supplies, network instability, dead UPS batteries, worn door hardware, and old Aiphone or buzzer intercoms limping along on forty-year-old wiring. Scheduled security camera maintenance is part of the same offer — lens cleaning, storage checks, firmware, and a written report — so the CCTV system you paid for is actually recording the night you need it.
We publish real MSRPs — over a hundred of them — in our equipment catalog, down to the Control iD garage tag readers that open the gate before the driver touches the window switch. Project math is public too: the camera installation cost guide, business camera budgets, access control costs, and condo intercom costs all show the same numbers we quote in person.
We work across the city of Chicago — River North, the Loop, West Loop, Gold Coast, Lincoln Park, Lakeview, Uptown, Rogers Park, and the neighborhoods between. See the Chicago service page for details.
We care about the full lifecycle: planning, installation, documentation, and ongoing support. That's how systems stay manageable in real buildings with real staff turnover.
Diagrams, cable labels, IP address tables, and credential inventories — so the next person who touches the system knows exactly what's there and how it works.
Proper VLAN segmentation, PoE budgets, UPS planning, and clean wiring so systems don't degrade over time or fail during outages.
We modernize without ripping everything out at once — planned cutovers with minimal disruption, reusing existing infrastructure where it makes sense.
Beyond the four core systems, we offer focused services for specific needs — from system takeovers to network engineering.
IP camera design and installation for garages, lobbies, loading docks, and building perimeters.
Upgrade analog cameras to modern IP systems while reusing existing cabling and infrastructure.
Offline cameras, failed recordings, foggy lenses, dead NVRs — diagnosed and fixed, even systems we didn't install.
Door control, key fobs, mobile credentials, and elevator integration with Brivo or Paxton.
Migrate from legacy fob systems to cloud-managed access control with full audit trails.
Troubleshoot and repair door controllers, readers, locks, and credential databases.
2N and ButterflyMX video entry panels for condos, offices, and multi-tenant buildings.
Replace outdated buzzer intercoms with modern video entry systems using existing wiring.
Structured cabling, managed switches, VLANs, and Wi-Fi coverage for commercial buildings.
Power over Ethernet budgets, UPS backup, and network infrastructure for security devices.
Audit existing security systems, document what's installed, and take over support from previous vendors.
Control iD long-range windshield-tag readers — the gate opens before the driver rolls the window down.
Scope decides it — door count, camera count, intercom needs, and what wiring already lives in the walls. A small system with 8 cameras and one access-controlled entry starts around $8,000 installed; bigger buildings scale from there, and we put every controller, reader, and cable run on its own line in the proposal. The math is public: see the camera installation cost guide and the access control cost guide.
Yes — condo and HOA buildings are our specialty, from vintage walk-ups to residential towers. We also handle offices, cafés and restaurants, and mixed-use properties across the city of Chicago.
Yes. We design unified systems where door access events trigger camera recording, intercom panels share credentials with access control, and everything runs on a properly segmented network. Brands like Brivo, Hanwha Vision, and 2N are designed to work together when installed correctly.
Yes — most of our repair calls are for someone else's work. Dead camera on a garage ramp, a fob reader that quit after a power surge, an Aiphone that crackles like an AM radio: we fix it, or tell you honestly when it isn't worth fixing. Call (872) 254-5015 for service.
Usually, yes. During the site survey we test the cabling, door hardware, camera mounts, and network — whatever passes, stays. Keeping good wiring in service is the single biggest cost saver in a retrofit, and the cutover runs door-by-door so the building never loses coverage.
