Speco Technologies TVIUTP4 4-Port TVI over UTP Balun
The Speco Technologies TVIUTP4 is a compact 4-port TVI (Television over Internet Protocol) to UTP balun designed to extend HD video transmission distances over standard unshielded twisted-pair cabling. This device serves as a critical link in TVI-based surveillance architectures, allowing integrators to leverage existing Category 5/5e/6 infrastructure without expensive new coax runs. The TVIUTP4 supports 5MP resolution video capture and operates within a compact, space-efficient form factor measuring 4.3" x 3.2" x 1", making it suitable for installation in telecom closets, equipment racks, or distributed deployment environments.
Key Features
- 4-Port TVI Input: Supports simultaneous transmission of four independent TVI video streams over UTP cabling, enabling multi-camera deployments without parallel coax infrastructure.
- 5MP Resolution Support: Capable of handling video streams up to 5MP (2592x1944 maximum resolution), accommodating both HD and mid-range megapixel camera payloads.
- UTP Transmission: Converts TVI signals for transport over standard unshielded twisted-pair copper cabling (Cat5e/Cat6), extending signal reach and reducing installation material costs.
- Compact Footprint: Dimensions of 4.3" x 3.2" x 1" and lightweight 0.4 lbs enable flexible mounting in space-constrained environments—telecom racks, wall-mounted enclosures, or equipment bundles.
- ONVIF Profile I Compatibility: Certified ONVIF compliance ensures interoperability with third-party VMS platforms, recorders, and network management tools supporting standardized device integration.
- Wired Connectivity: Direct UTP cabling connection with no wireless components, providing reliable, deterministic signal transmission in industrial, commercial, and institutional deployments.
Integration & Compatibility
The TVIUTP4 integrates into mixed-protocol surveillance systems where TVI cameras are already deployed or planned. ONVIF Profile I certification guarantees compatibility with VMS platforms that recognize ONVIF-compliant video encoders and transmission devices, streamlining system design and reducing vendor lock-in risk. The balun operates transparently within the signal chain—no configuration required—making it ideal for retrofit installations where existing TVI infrastructure must extend into areas previously served by IP-based systems. Integrators can deploy the TVIUTP4 in hub-and-spoke topologies, centralizing balun conversion in a single rack location or distributing units closer to camera clusters for optimal signal integrity.
This device is particularly valuable in facilities with extensive existing Category 5e or Category 6 cabling runs that were originally installed for voice, data, or older video standards. By repurposing these pathways for TVI transmission, security integrators avoid costly conduit work and minimize disruption to operations.
The lightweight, compact design accommodates both vertical rack mounting and horizontal shelf installation, offering flexibility in telecom closets or distributed node architectures. At 0.4 lbs, the TVIUTP4 places minimal load on mounting hardware and can be bundled with other equipment for efficient space utilization.

During a recent infrastructure assessment for a multi-building campus project, I evaluated the TVIUTP4 as a cost-effective way to extend TVI camera deployments across existing copper runs without adding coax. The device's 4-port configuration and compact size made it a practical fit for our telecom rack consolidation goals, and ONVIF compliance eliminated integration friction with our planned VMS.
Technical Highlights:
- 5MP Resolution Pass-Through: The TVIUTP4 handles full 5MP video payloads (2592x1944), preserving image quality for mid-range camera specs without transcoding overhead.
- ONVIF Profile I Certification: Ensures seamless connectivity with third-party NVRs, VMS platforms, and management software—a critical requirement in heterogeneous deployments where standardized protocols drive operational efficiency.
Deployment Considerations:
- UTP transmission distances are subject to cable quality and environmental factors; verify Cat5e/Cat6 runs are properly installed and tested before deployment to avoid signal degradation or sync issues.
- The compact 4.3" x 3.2" x 1" form factor is ideal for rack or closet mounting, but confirm adequate ventilation in enclosed spaces, as prolonged heat exposure can affect electronics reliability over time.
- Because the TVIUTP4 is a passive/active conversion device with no onboard processing, ensure upstream TVI cameras and downstream recording equipment are configured with compatible frame rates and compression settings to avoid latency or frame-drop scenarios.
For integrators standardizing on TVI infrastructure across larger campuses or multi-site operations, the TVIUTP4 represents a pragmatic entry point into distance extension without wholesale platform migration. Validate coax runs, confirm ONVIF compliance with your VMS, and you'll have a reliable, low-cost extension solution.
