With intuitive visualization tools and powerful diagnostic capabilities, NDI Checker transforms complex network data into actionable insights.

KEY FEATURES

NDI® Checker provides live analysis and monitoring of all NDI signals and network performance in your Broadcast and ProAV workflows. Designed for engineers, technical directors, and production staff who demand reliability during critical productions.

Select and Measure the Selected Signal

Take control over your monitoring workflow by isolating and analyzing individual NDI sources. This targeted approach allows engineers and technical directors to focus on critical signals during complex productions, enabling faster troubleshooting and more effective quality control. When issues arise, the ability to quickly select and measure specific signals can mean the difference between a minor adjustment and a production failure.

Simple Picture Display

Our intuitive picture display provides immediate visual confirmation of NDI signal integrity without overwhelming technical details. Production staff can instantly verify that the correct content is being transmitted, while engineers can use visual cues to identify issues that might not be apparent in numerical data alone. This feature bridges the gap between technical monitoring and practical production needs, ensuring everyone on your team has the visibility they require.

View the Video Format of the Selected NDI Signal

Immediately identify resolution, frame rate, color space, and other format details for any NDI source. This critical information ensures technical compatibility throughout your production chain and helps prevent cascading issues caused by format mismatches. Engineers can verify at a glance that each source meets your production requirements, while technical directors can confirm that signals will properly integrate with downstream systems.

View the Number of Frames Received in the Last Second

Live frame count monitoring provides immediate insight into stream stability and continuity. This second-by-second analysis helps identify intermittent issues that might otherwise go undetected, such as encoder problems, network congestion, or source instability. For live productions where every frame matters, this feature provides the confidence that your content is being delivered consistently and completely.

Measure the Bitrate of the Selected NDI Signal

Precise bitrate monitoring gives you essential information about bandwidth utilization and signal quality. Engineers can verify that each NDI source is operating within expected parameters, identify compression issues, and optimize network resources accordingly. By monitoring this key metric, production teams can ensure consistent quality while preventing network saturation that could impact multiple signals simultaneously.

Event Log Display with Monitoring of up to 100,000 Events

Comprehensive event logging with support for exporting logs to CSV provides unmatched diagnostic capabilities for complex NDI environments. With capacity for up to 100,000 events, the system maintains a detailed history of signal changes, errors, warnings, and network events. This extensive logging capability allows engineers to track intermittent issues over time, identify patterns in system behavior, and proactively address potential failures before they impact production.
