Comelit HFX-700W Single Button A/V 2-Wire Wi-Fi Intercom
The Comelit HFX-700W is a compact, rack-mount A/V intercom unit engineered for deployments where 2-wire infrastructure already exists and Wi-Fi connectivity can augment or replace hardwired runs. Its single-button design reduces operational complexity—useful when you need straightforward access control or building communication without multi-function keypads. This makes the HFX-700W practical for distributed intercom systems in multi-unit residential buildings, commercial access points, and retrofit installations where minimizing wiring changes is a cost driver.
Key Features
- Single-Button Interface: One-touch operation simplifies training and reduces user error in high-traffic access scenarios. No complicated menus or mode-switching—press once to initiate audio/video communication.
- 2-Wire Compatibility: Integrates with existing 2-wire intercom infrastructure, eliminating the need to run new copper or fiber to every station. Particularly valuable in older buildings or retrofits where Cat5e/Cat6 runs are cost-prohibitive.
- Wi-Fi Connectivity: Removes the last-mile wiring bottleneck. If your intercom hub and network backbone are already in place, the HFX-700W can reach remote areas via wireless without pulling cable through walls or conduit.
- Rack-Mount Form Factor: Designed for standard 19-inch equipment enclosures. This allows centralized mounting in security rooms, MDF closets, or server cabinets alongside your access control panel, NVR, or network switch—reducing hardware sprawl and simplifying cabling.
- Audio/Video Capability: Full A/V transmission over 2-wire ensures the person at the HFX-700W can both speak and see the visitor or area being monitored. Critical for positive identification and two-way conversation in access-control workflows.
- Comelit Ecosystem Integration: Works within the Comelit intercom product line, supporting multi-unit residential and commercial deployments that already standardize on this platform.
Integration & Compatibility
The HFX-700W is designed for Comelit intercom systems and compatible 2-wire infrastructure. Its Wi-Fi capability integrates with standard 802.11 networks, so deployment doesn't demand proprietary wireless hardware. If you're planning a building-wide intercom refresh or adding remote communication to an existing access control setup, confirm that your hub or master station is Comelit-certified to support the HFX-700W's 2-wire protocol variant.
For installations combining video intercom with access control, coordinate with your access control integrator to ensure door-unlock signaling aligns with intercom call logic. Many integrators pair intercoms with electric strikes or magnetic locks; the HFX-700W's single-button design plays well with simple one-action door triggers.
Deployment Considerations
Consider the HFX-700W when you have:
- Existing 2-wire runs that are still functional and you want to extend coverage via Wi-Fi rather than abandon them.
- A need for low-complexity user interfaces—lobbies, gatehouse entries, or remote access points where visitors shouldn't require instructions.
- Rack-space availability in a central location, such as a building control room or security office.
- A Comelit system already in operation, reducing integration risk and training overhead.
If your building is new construction or a large-scale replacement, evaluate whether native IP-based intercom stations might offer faster deployment and richer feature sets. For retrofit and distributed access scenarios with existing 2-wire infrastructure, the HFX-700W minimizes disruption.
Frequently Asked Questions
Q: Is the HFX-700W compatible with older Comelit 2-wire intercom systems?
A: Yes, the HFX-700W is designed for Comelit 2-wire infrastructure. Confirm with your system documentation or installer that your master station and hub support this endpoint model.
Q: Can I mix HFX-700W units with other Comelit intercom models on the same system?
A: Typically yes, but verify with your Comelit system configuration guide. Multi-model deployments are common, but endpoint compatibility depends on your hub firmware and protocol version.
Q: Does the HFX-700W require Wi-Fi for basic 2-wire operation?
A: No. The unit works over traditional 2-wire connections independently. Wi-Fi is an optional augmentation; you can deploy it purely on 2-wire if your network isn't ready or available.
Q: What is the typical power consumption of the HFX-700W?
A: Exact power specs are in the manufacturer datasheet. Contact your Comelit distributor or check the product documentation for current/voltage ratings before sizing power supplies or UPS capacity.
Q: Can the HFX-700W be wall-mounted, or is rack-mounting mandatory?
A: The HFX-700W is engineered for rack-mount installation. If wall-mount or pedestal deployment is required, consult with your integrator about alternative Comelit models or custom mounting solutions.
Q: What happens if Wi-Fi is unavailable?
A: The unit continues to operate over its 2-wire connection. Wi-Fi is a convenience feature for extending range; loss of wireless does not disable the intercom.

The Comelit HFX-700W lands in a specific niche: retrofit and retrofit-adjacent deployments where 2-wire infrastructure is already in place and you need to extend A/V intercom reach without massive rewiring. If you're modernizing a building that still runs copper 2-wire to remote gates, lobbies, or loading docks, this unit is a pragmatic choice. The single-button interface is also its strength—less configuration surface area means fewer support calls and faster user adoption.
Technical Highlights:
- Dual-Mode Transport (2-Wire + Wi-Fi): The HFX-700W can operate over hardwired 2-wire alone or augment it with wireless. This flexibility is valuable in retrofits where you might deploy a Wi-Fi backhaul from the intercom hub to a distant building wing without running new cable.
- Rack-Mount Enclosure: Standard 19-inch format means you consolidate intercom, access control, and network infrastructure in one cabinet. Reduces clutter and simplifies maintenance when the master station, power distribution, and network switch all sit in the same footprint.
- Comelit Protocol Native: Works natively with Comelit hubs and master stations—no third-party gateways or protocol adapters needed. Simpler architecture translates to lower deployment cost and fewer single points of failure.
Deployment Considerations:
- 2-Wire Assumption: The HFX-700W assumes you already have functional 2-wire runs or are willing to install them. If your building is new construction or a large retrofit to pure IP, evaluate native IP intercom stations instead—they'll be faster to roll out and eliminate legacy copper dependencies.
- Single-Button Trade-off: Simplicity is the goal, but verify that one-touch operation meets your access workflows. If your building requires entry codes, call transfer, or directory lookup, you'll need a more feature-rich endpoint or a companion access control keypad at that location.
The HFX-700W is most at home in multi-unit residential complexes, commercial lobbies with remote gatehouse or loading-dock stations, and retrofit scenarios where a centralized security office uses a Comelit master station and a handful of remote HFX-700W units handle visitor communication. Pair it with a standard PoE network infrastructure and a modest Wi-Fi access point, and you've got a low-friction way to extend intercom coverage across a distributed campus.
