Comelit KCA2071A Hands-Free Video Intercom for CIAO & SimpleBus 2
Overview
The Comelit KCA2071A is a hands-free video intercom unit designed to integrate into existing Comelit CIAO and SimpleBus 2 intercom systems. It's built for multi-unit residential and small commercial deployments where you need video verification at entry points without requiring a separate handset or monitor. The unit delivers 4MP resolution — enough clarity to confirm visitor identity at typical door-to-camera distances — and runs entirely off PoE+ power, eliminating the need for dedicated 12V or 24V supplies at the device location.
Key Features
- 4MP Resolution: Captures 2560 × 1920 pixel video, providing sufficient detail for facial recognition and visitor identification at typical residential entry distances (4–8 feet). This is a practical step up from 2MP for modern security workflows where ID clarity matters.
- PoE+ (802.3at) Power: Draws power directly from a standard PoE+ network port. No separate 12V power injector or conduit needed — simplifies rough-in and reduces installation labor, especially in retrofit scenarios where power routing is already constrained.
- Hands-Free Design: Unit operates without a separate indoor handset or call button, making it ideal for lobbies, apartment building foyers, or small commercial entrances where space is limited or traffic volume is high. Audio and video flow to connected SimpleBus 2 devices on the network.
- SimpleBus 2 & CIAO Ecosystem: Integrates natively with Comelit's existing intercom infrastructure — compatible with their modular system architecture. This means you can add the KCA2071A to an existing deployment without replacing the central unit or rerunning all cabling.
- Network-Based Architecture: Operates over standard Ethernet, allowing placement anywhere on your facility network (subject to PoE+ availability). Audio and video are delivered to designated intercom stations on the same network.
- Compact Form Factor: Hands-free units are typically wall-mounted at entry points, occupying minimal physical space while remaining visible and accessible to visitors.
Integration & Compatibility
This unit is purpose-built for Comelit CIAO and SimpleBus 2 systems. Before ordering, verify that your existing intercom infrastructure supports the KCA2071A — compatibility depends on system version, firmware revision, and configuration. You'll need PoE+ capable network infrastructure (either inline injectors or a PoE+ switch with sufficient power budget). Standard wall-mounted installation applies; mounting surfaces and weatherproofing depend on your indoor or outdoor entry environment.
Installation requires basic network provisioning (DHCP or static IP assignment) and configuration within your SimpleBus 2 management interface. Comelit's documentation (available via your distributor or Comelit directly) will detail the specific steps for adding the KCA2071A to your system and assigning call routing to connected indoor stations.
When to Choose a Different Model
If you need a higher-resolution or multi-sensor unit, consult the broader Comelit IP camera line for alternative intercom or video entry solutions. If your facility requires outdoor-rated (IP67) hands-free units with long-distance IR illumination, you may need a higher-spec model or a hybrid entry system combining a dedicated outdoor camera with a separate hands-free speaker unit. If you're still in the planning phase, reviewing camera and system selection guidance will help clarify whether a hands-free intercom or a traditional video door camera better suits your deployment.
Frequently Asked Questions
Q: Is the KCA2071A compatible with my existing CIAO system?
A: Compatibility depends on your specific CIAO version and SimpleBus 2 configuration. Consult your system documentation or contact Comelit support to confirm that your central unit and firmware support the KCA2071A before purchasing.
Q: What PoE+ power budget does the KCA2071A consume?
A: Exact wattage is not specified in available documentation. Contact Comelit or your distributor for the maximum power draw to ensure your PoE+ switch or injector has sufficient headroom for all connected devices.
Q: Can I wall-mount the KCA2071A outdoors?
A: No IP or IK rating is documented. Treat the KCA2071A as an indoor-rated unit unless your distributor or Comelit explicitly confirms outdoor suitability for your climate and application.
Q: Does the KCA2071A support two-way audio?
A: Two-way audio capability is not explicitly detailed in available specifications. Confirm audio features with Comelit or your system integrator before installation.
Q: What compression codecs does the KCA2071A support?
A: Compression format (H.264, H.265, MJPEG) is not specified in available data. Check the manufacturer datasheet or system documentation for codec details.
Q: Is there a warranty on the KCA2071A?
A: Warranty terms are not provided in current specifications. Contact Comelit or your specialty distributor for warranty coverage and support terms.

The Comelit KCA2071A fills a specific niche: hands-free entry for systems where you don't want a visible call button or wall-mounted handset cluttering the entry. At 4MP, the resolution is adequate for residential multi-unit buildings and small commercial lobbies — you'll get a clear enough image to confirm a delivery driver or maintenance tech before buzzing them through. The PoE+ power model cuts labor on rough-in: one Ethernet run covers both data and power, which matters when you're retrofitting older buildings where 12V low-voltage runs aren't already in place.
Technical Highlights:
- 4MP Sensor: Delivers 2560 × 1920 pixel video — a practical sweet spot for 4–8 foot visitor distances. You'll have enough detail for basic facial ID without over-specifying the system or inflating storage and bandwidth consumption.
- PoE+ (802.3at) Powered: Eliminates a separate power supply and simplifies cabling in retrofit or space-constrained entry points. Ensure your switch has PoE+ capacity — standard 802.3af won't cut it.
- Integrated into SimpleBus 2 Architecture: No additional gateway or bridge required if you already run CIAO or SimpleBus 2. Call routing, audio delivery, and user provisioning are handled through your existing intercom management interface.
Deployment Considerations:
- No IP/IK Rating Published: This is an indoor-rated device. Do not attempt exterior mounting in rain, direct sun, or humidity-heavy environments unless Comelit explicitly certifies it — you'll lose the unit fast.
- Compatibility Gate: SimpleBus 2 and CIAO come in multiple generations and firmware levels. Verify your system version supports the KCA2071A before committing. One failed installation costs more than one vendor call.
- Audio & Codec Specs Undocumented: Two-way audio, compression format, and frame rate are not detailed in current specs. Confirm these with Comelit before finalizing the design — they affect user experience and network planning.
Position the KCA2071A in multi-unit residential lobbies or small commercial foyers where you want video verification without the visual footprint of a traditional video door station. It's also practical for buildings that already standardized on Comelit intercom infrastructure and want to add video without hardware overhaul. Skip it if you need outdoor durability, long-range IR, or highest-spec entry video — that's a different product family.
