The Kiloview KA-TL1 External Tally Light (also cataloged under regional part number CL-VZ-5200110) is a compact, ultra-lightweight signaling accessory designed for NDI and NDI|HX live video production environments.
While some Kiloview devices have built-in tally lights, the KA-TL1 serves as an externally positionable extensions module. It connects directly to Kiloview hardware encoders and converters to give on-screen talent and camera operators a bright, unmistakable indication of live on-air status.
Core Engineering and Operational Features
-
Dual-Sided LED Signaling: To ensure clear communication across the studio floor, the unit features independent, bright LED indicators on both the front and the rear of its housing. This allows the camera operator behind the rig and the presenter standing in front of the lens to simultaneously monitor live cues.
-
Intelligent Two-Color Tally States: The LED module integrates seamlessly with NDI metadata commands transmitted by popular production switchers (such as vMix, NewTek TriCaster, and OBS Studio), triggering two standard industry cueing states:
-
Bright Red: Indicates Program (PGM) mode—the camera is live to air.
-
Vibrant Green: Indicates Preview (PVW) mode—the camera is cued up next in line.
-
-
Driverless USB-C Topology: The hardware bypasses the need for independent battery packs or wall power bricks. It utilizes a single, direct USB Type-C cable connection to hook into its parent Kiloview encoder, drawing its electrical power and real-time NDI tally control data packets down the same line.
-
Flexible Mounting Mechanics: Built into the bottom of the featherweight enclosure is a standard 1/4"-20 threaded mounting point. Combined with the included shoe adapter hardware, it allows production crews to freely mount, adjust, and position the light ring on cold shoes, articulating magic arms, or tripod hardware handles.
Core Device Compatibility Architecture
The signaling architecture of the KA-TL1 is custom-tailored to expand Kiloview's mobile and field-tier IP video transmission lines:
-
E-NDI Series Wired Encoders: Kiloview E1-NDI (3G-SDI to NDI) and E2-NDI (HDMI to NDI) systems.
-
N-Series Mobile Wireless Nodes: Kiloview N1 (3G-SDI to wireless NDI) and N2 (HDMI to wireless NDI) portable converters.

💡 Operational System Tips for the KA-TL1 Module
The Lens Field-of-View Safety Adjustment: Because the KA-TL1 is designed to be mounted on top of a camera rig or hot shoe, always double-check your lens framing—especially when shooting with ultra-wide zoom profiles (e.g., 16mm or 24mm equivalent lengths on full-frame sensors). Because the tally light sits forward on its bracket to maximize visibility for the host, a poorly positioned module can creep into the upper edge of your video crop frame. Use an articulating magic arm to lift the tally box slightly higher and backward along the vertical camera axis to keep it clean out of your sensor's active capture zone.
-
Managing Cable Strain on Shifting Rigs: Weighing a mere 36 grams, the tally light housing can be pulled off alignment by the weight of a heavy USB-C cable if it hangs loosely. When routing the cable down to your E1-NDI or N2 encoder module, loop the thin USB-C line tightly against your camera's handle or cage assembly using a basic touch-fastener band. This provides an effective cable strain relief point, preventing sudden panning or tilting from straining the tally light's delicate internal USB port connection.
