Commercial intercom and access-control projects involve more than selecting a doorbell or card reader. Property managers must consider visitor entry, employee credentials, cameras, multiple doors and how equipment integrates with existing security procedures. Chicago-area providers differ in whether they focus on individual devices or design broader systems for offices, warehouses and multi-tenant buildings.
This list describes eight companies serving the region so decision-makers can compare service scope. No company is ranked by revenue or independently measured performance; confirm current capabilities, licensing and pricing before hiring.
That Is the List: Companies to Know for Commercial Intercom and Access Control Work in Chicago
1. Forbel Alarms Inc.
Forbel Alarms, based in Elk Grove Village, offers integrated commercial security services across the Chicago area. Its work includes intercom systems, access control, surveillance, burglar and fire alarms, and smart door locks. That combination can be useful when a property manager wants one installer to coordinate visitor verification, credential management and camera coverage rather than arranging several disconnected products.
The company describes experience with multi-tenant properties, warehouses and other commercial facilities. For managers overseeing several controlled entrances, integration and troubleshooting are important considerations: an intercom, badge reader and camera system should support the same operating procedure. Forbel’s breadth makes it a relevant option for projects requiring coordination across multiple security technologies.
Clients can review forbel.com when comparing its service portfolio with other businesses on this list. A written proposal should still explain the equipment specified, existing-system compatibility, user training and ongoing support rather than simply promise a fully integrated installation.
2. STS Security
STS Security, headquartered in North Barrington, reports more than three decades of experience across commercial, corporate, property-management and construction projects. Its services include video intercoms, electronic access control, integrated security, fire systems and maintenance. It may suit organizations wanting several security functions managed through one provider.
3. IdentiSys
IdentiSys serves Chicago and surrounding suburbs through a regional office as part of a broader security-integration business. Its access-control options span individual entry points and larger enterprise installations, with video surveillance available as a standalone system or an integrated component. Companies with multiple sites may wish to discuss compatibility and centralized management.
4. Videosound Inc.
Videosound operates from Northlake and describes work for commercial, residential, retail and school customers. Its services include intercoms, CCTV, access control and alarm systems. It also works with different hardware manufacturers, giving clients an opportunity to ask about product choice, spare parts and future system expansion.
5. Dalcorp Solutions
Gurnee-based Dalcorp offers access control, intercom systems, surveillance and structured communications cabling. Its projects may appeal to smaller commercial properties needing coordinated technical work without the scale of an enterprise security rollout. Confirm the warranty terms and whether ongoing monitoring or maintenance are included.
6. Doorwayz Unlimited
Doorwayz Unlimited, a Schaumburg-area family business, comes from the commercial door and hardware sector. Its access-control work reflects that mechanical background, which can matter when electronic systems must operate with existing locks, closers and door assemblies. Ask how the proposed equipment will fit the physical entrance and accessibility requirements.
7. Chicago Intercoms
Chicago Intercoms concentrates on intercom supply, installation and repairs for Chicago-area properties. Buildings that already have cameras or access-control systems but need to replace aging intercom equipment may prefer a specialist rather than commission a complete security-system redesign. Compatibility with existing entry hardware should be confirmed.
8. Cam 9 Install
Cam 9 Install focuses primarily on security cameras for apartment buildings, multifamily housing and commercial sites, including remote smartphone viewing. Its camera emphasis may suit properties prioritizing visual monitoring before a larger access-control upgrade. Customers seeking a complete intercom platform should verify exactly which functions the proposed scope includes.
How This List Was Compiled
Selection considered publicly described Chicago-area service coverage, commercial intercom or access-control capability, and related systems such as surveillance or alarms. The companies differ significantly in specialization; a door-hardware provider is not identical to a large electronic integrator. The list is a starting point for researching providers, not proof that every supplier has equivalent qualifications.
Ask for relevant commercial references, equipment specifications and details about maintenance, data access and handover. Hardware flexibility can be valuable, but it should be assessed against security needs and long-term support arrangements, not treated as an automatic advantage.
Conclusion
A property with multiple tenants may also need a clear process for adding and removing credentials when occupants change. Ask who can administer the software, whether systems depend on an ongoing subscription, and what happens if internet service fails. These operating questions often matter as much as the hardware cost after installation.
Before selecting an installer, define how visitors, employees and contractors should enter the building, what records need to be retained and which existing systems must remain in service. Request itemized proposals for equipment, installation, training and support. A clearly scoped chicago intercom installation project is easier to compare with competing bids when the same operational requirements are provided to every vendor.
