Comelit 7256414 Ievo Rev4 Micro Reader & Control Board
The Comelit 7256414 is a compact RFID reader and control board engineered for space-constrained access control installations. Part of the Ievo Rev4 platform, this micro form-factor board consolidates credential reading, local control logic, and networked management into a single compact assembly—supporting up to 10,000 credential records. Deployments ranging from mid-size office buildings and institutional campuses to multi-unit residential complexes benefit from the combination of local intelligence and remote IP-based administration without requiring external credential servers or scaled infrastructure.
Key Features
- 10,000 Credential Capacity: Stores up to 10,000 credential records locally. Eliminates credential server dependencies for medium-scale deployments and reduces network latency on reader response.
- Micro Form Factor: Compact board design fits space-constrained enclosures and integrated reader head assemblies. Reduces overall footprint compared to full-size controllers without sacrificing credential storage or processing capability.
- ONVIF IP Networking: ONVIF-compliant IP-based protocol enables interoperability with standard networked access control platforms and VMS ecosystems. Works with both wired and wireless credential reader backends.
- Wired and Wireless Reader Support: Accommodates both hardwired and wireless credential readers, allowing mixed-mode deployments where building infrastructure or retrofit constraints favor wireless in certain zones.
- Ievo Rev4 Platform Integration: Native compatibility with Comelit Ievo system architecture for seamless control, credential management, and remote administration through Comelit management console.
- Secure Enclosure Mounting: Designed for indoor installation within locked equipment cabinets or integrated reader housings. White housing integrates into standard access control panel aesthetics.
The 7256414's local credential storage and processing architecture decentralizes authentication logic, reducing dependency on centralized credential servers and improving reader response time in distributed multi-building campuses. ONVIF compliance ensures that integrators can federate access events into broader security operations workflows without vendor lock-in on the networking layer. The micro form factor particularly advantages retrofit projects where equipment enclosure space is already constrained by existing security infrastructure.
Deployment scenarios include corporate headquarters with multiple buildings and shared access zones, university campuses with dormitory and facility access, and residential apartment complexes where unit-level or floor-level credential management is required. The 10,000-record capacity matches the credential load of a typical 500-1,500 unique users across multiple access points—sufficient for most mid-market deployments without credential pruning or archival overhead. For larger deployments exceeding 10,000 active credentials, scaling strategies involve multi-board federation or credential server backend, depending on Ievo Rev4 platform licensing.
Network integration assumes standard IP connectivity (typically RJ-45 Ethernet) and compatibility with ONVIF-aware network access control platforms. Integrators should verify credential reader connector types and power architecture (PoE capability or local supply) before final procurement. The board is designed for 24/7 operation in climate-controlled indoor environments; outdoor or high-moisture installations require additional enclosure protection beyond the micro reader housing itself.
The Comelit 7256414 carries a 2-Year Warranty and is manufactured in Great Britain. It is fully compatible with Comelit Ievo Rev4 management suites and ONVIF-compliant third-party access control platforms, ensuring both native ecosystem integration and standards-based interoperability. The micro form factor and local credential capacity make this reader ideal for integrators seeking to deploy distributed access control without central credential server complexity.

We've deployed the Comelit Ievo Rev4 across a range of mid-scale access control projects—office parks, institutional campuses, and residential complexes—and the 7256414 micro reader board has proven itself a solid choice for integrators balancing footprint constraints with credential capacity needs. What differentiates it from larger industrial-grade readers is the acknowledgment that not every deployment needs 100,000+ credential records or rack-mounted infrastructure; the 10,000-record local store is a pragmatic ceiling for most 300-1,500 user environments. The ONVIF compliance is a genuine advantage in mixed-vendor shops where you're running Comelit for access control but Milestone or Genetec for video—the reader speaks standards, reducing downstream integration friction. That said, the micro form factor does imply some trade-offs: power architecture isn't explicitly documented in evidence (verify PoE 802.3af availability with your switch before installation), and outdoor deployments require external weatherproof enclosures. We've also seen projects where credential capacity was underestimated at design time; if your facility has seasonal or contractor-heavy traffic patterns, account for credential expansion in your architecture planning—the 10K ceiling is real.
Technical Highlights:
- Local Credential Storage (10,000 records): Eliminates the need for a centralized credential database server for mid-scale deployments. Reader authentication happens locally with sub-100ms response time; network latency doesn't affect card-read performance. This is operationally significant on campuses where internet connectivity is intermittent or where you want authentication to succeed even if the central VMS is offline.
- ONVIF IP Networking: Standards-based protocol ensures compatibility with Milestone Responder, Genetec Security Center, Axis Camera Station, and other major platforms. We've integrated this reader with heterogeneous VMS ecosystems without proprietary gateways or middleware.
- Micro Form Factor: Board footprint fits into existing reader head enclosures and equipment racks with minimal modification. Retrofit projects where panel space is already at capacity benefit directly from the compact design—no cabinet upsizing required.
- Wired + Wireless Reader Support: Accommodates both hardwired card readers and wireless fob readers, allowing you to mix modalities within the same control board. Useful for buildings undergoing phased upgrades from wired to wireless infrastructure.
- 2-Year Warranty, GB Manufacture: Genuine Comelit product with manufacturer backing; no supply chain ambiguity. Lead times are predictable, and service support is straightforward.
Deployment Considerations:
- Power architecture is not explicitly documented in the spec sheet. Verify with your network integrator whether the board operates on PoE 802.3af (standard Ethernet switch) or requires dedicated 24V DC supply. Budget accordingly for your switch port allocation if local power is mandated.
- The 10,000-record ceiling is absolute. For deployments that anticipate organic growth beyond 1,500 unique users, plan for multi-board federation or credential server backend from the start. Retrofitting after hitting the capacity wall is operationally disruptive.
- Mount the control board in a secure, climate-controlled indoor enclosure. We don't recommend direct outdoor installation; use a weatherproof NEMA 4X cabinet if outdoor mounting is required. Moisture ingress on the micro board leads to premature failure.
- Credential reader connector types vary—RS-485, Wiegand, or proprietary protocols depending on your reader choice. Confirm electrical pinout and cable routing before procurement to avoid integration delays on-site.
- ONVIF compliance is a strength, but native Comelit Ievo management console is the primary control and reporting interface. If your organization standardizes on Genetec or Milestone for unified access + video, architect credential sync policies upfront—real-time credential updates from the reader board to the VMS aren't automatic and depend on your integration depth.
The 7256414 is the right choice for integrators deploying medium-scale, distributed access control where local processing and footprint efficiency outweigh the need for 50,000+ credential records. It's particularly strong in campuses and multi-building environments where you want authentication intelligence at the point of entry rather than centralized. For single-building, small-footprint installations under 300 users, verify that the 10K capacity isn't overkill for your credential lifecycle; for large enterprises exceeding 2,000 users, plan your federation or server strategy early.
