An intercom system is how a property lets visitors identify themselves before being let in — whether that’s a single-family gate, an apartment lobby, or a commercial entrance. Pricing varies more than people expect because "intercom" covers everything from a basic audio-only unit to a fully networked video system tied into access control.

What Goes Into an Intercom System
Quick answer: A complete intercom system covers the entry call station (audio or video), the interior answering unit or app, wiring or network connectivity, and often integration with a gate or door release.
The entry station is what a visitor interacts with — pressing a button or scrolling a directory to call a specific unit. On the other end, residents or staff answer via a wall-mounted panel, a phone line, or increasingly a smartphone app. See our video intercom system guide for how video-specific systems work.
Intercom Installation Cost by System Type
Quick answer: A basic audio-only intercom typically runs $500–$1,200 installed. A single-family video intercom typically runs $800–$2,000. Multi-tenant video intercom systems typically run $2,500–$10,000+ depending on unit count.
| System Type | Estimated Cost Range |
|---|---|
| Basic audio intercom | $500–$1,200 |
| Single-family video intercom | $800–$2,000 |
| Gate telephone entry system | $1,200–$3,500 |
| Multi-tenant video intercom | $2,500–$10,000+ |

What Drives the Price Up or Down
- Audio vs. video — video adds camera hardware and network requirements over audio-only.
- Number of units/tenants — multi-tenant directory systems scale in cost with unit count.
- Gate or door integration — tying the intercom to a gate release or access control adds wiring and programming.
- Mobile app vs. hardwired answering — app-based systems add ongoing platform cost but reduce wiring.
Code and Accessibility
Intercom entry stations serving the public should account for ADA accessibility, including mounting height and usable controls. Installers in Texas are licensed through the TDLR — ours is License #B31188501.
Intercom Installation Across Dallas, Fort Worth and Allen
Gate telephone entry systems are common at HOA and gated community entrances across Allen, Plano and Frisco, while multi-tenant video intercom is more common in apartment and multifamily buildings closer to Dallas and Fort Worth's urban core.
Residential vs. Commercial vs. Multifamily
Residential properties typically use a simple video intercom at the front door or a gate telephone entry unit — see our gate installation cost guide for how these pair.
Commercial properties often pair an intercom with access control at a main entrance for visitor screening.
Multifamily and apartment properties need a directory-based system supporting many units — see our apartment and multifamily intercom guide.
Common Mistakes
- Choosing audio-only for an entrance where visual identification matters for security.
- Underestimating network requirements for a video intercom system.
- Not planning for future unit additions in a multi-tenant directory system.
Installation Process
- Site assessment — entry point, unit count, and network availability.
- System design — audio vs. video, standalone vs. gate/access control integration.
- Written estimate — itemized by hardware, wiring, and any platform licensing.
- Installation and programming — mounting, wiring, and directory setup.
- Testing and walkthrough — confirming call quality and any gate/door release function.
