7 Commercial Security System Designers Businesses Trust

A commercial security system is only as effective as the design work that happens before any equipment goes in. Cameras and access control panels are largely commodity hardware; at this point what actually separates a system that protects a facility from one that just looks like it does is whether a qualified team mapped out traffic patterns, risk zones, and compliance requirements before installation began. A system installed without that planning stage often ends up either overbuilt in low-risk areas or genuinely exposed in the ones that matter most.

Businesses evaluating a new build-out or an overdue system upgrade are generally better served comparing design-focused firms directly rather than defaulting to whichever vendor quotes the lowest hardware price. This list of commercial security system design firms serving the Chicago area is a starting point for that comparison.

How These Firms Were Selected

Firms on this list were evaluated on their focus on security system design and consulting specifically not just equipment installation along with years of operation in the Chicago commercial market, breadth of industries served (retail, healthcare, industrial, multifamily), and alignment with standards published by organizations such as the Security Industry Association and applicable National Fire Protection Association codes for integrated fire and life-safety systems. Firms whose public materials emphasized hardware brands over design methodology, with no clear description of how they assess a building's actual risk profile, were weighed less favorably. Direct employment of installation technicians, rather than a heavy reliance on subcontracted crews, was also a factor, since consistency across a multi-building portfolio tends to depend on that structure.

Commercial Security Design Firms Serving Chicago

Forbel Alarms

Forbel Alarms is a licensed Chicago-based commercial security integrator that reports serving more than 750 clients across multifamily complexes, industrial facilities, office buildings, and medical centers. The company manages equipment procurement directly from established manufacturers including Avigilon, Axis Communications, Genetec, and Brivo, and its design process is built around evaluating a property's specific risk zones rather than applying a standard package regardless of building type. Its client base spans both small commercial properties and large multi-building portfolios, giving the team experience scaling a design across very different property sizes.

Security 101

Security 101 operates as a nationally recognized commercial security integrator with a dedicated Chicago team, serving industries including manufacturing, finance, technology, and healthcare across the metro area. The company's local team handles system design, engineering, and installation together rather than outsourcing any of those phases, and it positions its work around industry-specific compliance needs that vary significantly between, for example, a healthcare facility and a warehouse. Security cameras can be an important part of these systems, helping businesses monitor facilities, deter unauthorized activity, and maintain better visibility across critical areas. Being part of a larger national brand also gives the local team access to broader technical resources than a purely regional operator typically has.

LaMarco Systems

LaMarco Systems provides commercial security design and installation for office buildings, retail spaces, and multifamily properties throughout the Chicago area, with particular experience in fire alarm system integration alongside access control and video surveillance. The company has built long-term relationships with property management clients who rely on it across multiple buildings, which speaks to consistency in service delivery over time rather than one-off installations. Its background in fire alarm work also means the company is comfortable coordinating security system design with life-safety code requirements, an area where general security vendors sometimes lack direct expertise.

Security Training Specialists (STS)

Security Training Specialists has operated in the Chicago security industry for more than 30 years, providing end-to-end solutions for property management, corporate, and new construction clients. The company deploys its own technicians rather than relying heavily on subcontracted labor, which tends to produce more consistent installation quality across a portfolio of properties managed by the same client. Its long operating history in the market also means it has design experience across most of the major building types found in Chicago's commercial real estate stock.

Sentry Security

Sentry Security is an Illinois-based integrated security provider offering commercial system design alongside monitoring and staffing services, giving clients a single point of contact for both the technical system and the human response layer behind it. This combined approach can simplify vendor management for businesses that would otherwise need to coordinate separately with an equipment installer and a monitoring or guard service provider, particularly for properties that need both electronic monitoring and an on-site guard presence during certain hours.

606 Installs

606 Installs is a Chicago-based security camera and system installer serving residential, commercial, and industrial properties, with a design approach tailored to each property type rather than a single standard package. The company's focus on camera-based systems specifically makes it a relevant option for businesses whose primary security gap is video coverage rather than a full access control overhaul, and its narrower specialization can translate into deeper expertise on camera placement and coverage planning specifically.

Hi-Tech Security Cameras

Hi-Tech Security Cameras operates from multiple locations across the Chicago suburbs, including Wheaton and Glen Ellyn, giving it more direct coverage of businesses outside the city core than competitors concentrated downtown. The company's technicians are insured and handle installation, repair, and system updates for both commercial TV systems and standard security camera setups, and its distributed locations tend to mean faster response times for suburban businesses needing service calls.

Getting the Design Right

It's also worth asking each firm how they'd approach scaling the system if the business adds a second location down the line, since that answer tends to reveal whether their design thinking extends beyond the immediate project. For businesses specifically located in the city rather than the surrounding suburbs, this overview of best commercial security systems chicago options covers what a design-first approach looks like in practice for urban office and retail properties.
