Why Professional Communication Matters on Set

In film, commercial, reality, and live broadcast productions, timing and coordination are everything. A single miscue—whether a delayed camera movement, missed audio cue, or lighting error—can waste hours and inflate production costs. For crews operating across Bangkok, Phuket, Chiang Mai, Pattaya, or remote Thai locations, instant and reliable communication is essential.

Traditional communication methods, such as shouting, hand signals, or walkie-talkies, often fall short. Shouting is inefficient and noisy, hand signals require line-of-sight, and walkie-talkies with push-to-talk introduce delays and are limited in capacity. On complex shoots with multiple cameras, live streaming, or reality show setups, these methods cannot meet the demands of professional crews.

This is where a professional wireless intercom system becomes indispensable. Our Eartec UltraLITE system, featuring 13 headsets and 2 HUB stations, allows full-duplex communication across large teams, keeping every department—from directors and producers to camera operators, lighting, sound, and PAs—connected in real time.

Overview of Eartec UltraLITE

The Eartec UltraLITE is a full-duplex wireless intercom system that enables simultaneous talk and listen capabilities, mirroring a natural conversation. Unlike push-to-talk devices, it eliminates delays and miscommunication, making it ideal for professional production environments.

All headsets are wireless and self-contained, eliminating the need for belt packs or additional wiring. The DECT wireless technology provides stable connections even in RF-heavy environments, while lightweight, ergonomic headsets ensure comfort during long shooting days.

Compared to systems like Hollyland Solidcom, the UltraLITE offers distinct advantages: full-duplex audio, larger team capacity, easier deployment, and superior comfort. Lugged systems often require heavy belt packs, have shorter range, or limited user scalability, which makes UltraLITE the preferred choice for demanding productions in Thailand.

Complete Rental Package for Thailand Productions

Our rental package includes 13 full-duplex wireless headsets and 2 HUB stations, each capable of supporting up to eight headsets. The HUBs can be linked together via an Interlink cable, creating a single unified network for up to 16 users or more.

Every headset and HUB is fully charged, paired, and tested before delivery, ensuring production-ready reliability. The kit is designed for studios, outdoor locations, live concerts, and multi-camera reality shows, making it flexible for any scenario.

Headset Distribution for Large Teams

For an optimal setup on a production with 13 headsets:

• Director for overall control

• Producers and script supervisors for coordination

• Camera operators covering multiple angles

• 1st AC and focus pullers managing camera adjustments

• Steadicam or drone operators for mobile shots

• Sound mixer and boom operators for audio coverage

• Gaffer and lighting assistants for lighting coordination

• PAs or runners and script/continuity staff with optional receive-only mode

This layout ensures all key departments are fully connected while reducing channel clutter for support staff.

Real Production Scenarios in Thailand

Reality Shows in Isan: On sprawling outdoor locations with multiple camera positions, two HUBs can cover separate clusters—one near the director and video village, the other near camera operators and sound. Full-duplex communication allows the director to manage multiple action points in real time, coordinating camera movements, audio cues, and lighting adjustments efficiently.

Live Concerts in Bangkok: Large stage productions with simultaneous live streaming require instant cueing. HUB #1 placed at front-of-house and HUB #2 backstage allows stage managers, camera operators, lighting technicians, and audio engineers to communicate seamlessly. This ensures perfectly timed transitions and smooth broadcast execution.

Corporate Commercials in Phuket: Tight studio environments with multiple cameras and complex lighting setups benefit from strategic HUB placement. Directors can communicate instantly with camera and lighting teams, minimizing retakes and optimizing shooting time.

Travel and Documentary Shoots: Mobile crews covering multiple locations across Thailand rely on wireless, full-duplex communication. The UltraLITE system allows teams to coordinate actions without cables, belt packs, or delays, maintaining efficiency across diverse environments.

HUB Placement and Headset Optimization

Correct placement of HUBs is critical for maintaining signal stability and coverage. A HUB should be positioned near the director or control area, while the second HUB should be close to camera, lighting, or sound clusters. For outdoor or large sets, elevating HUBs and avoiding interference from metal structures ensures optimal range.

Headset management also improves efficiency: assigning primary speaker roles prevents overlapping communication, while optional receive-only modes for support staff reduce channel congestion. Maintaining fully charged batteries and testing DECT range prior to shooting guarantees uninterrupted operation.

Advantages of Renting Our Eartec UltraLITE

Practical Tips for Maximum Efficiency

• Assign dedicated primary speakers for critical roles to avoid talk-over

• Link HUBs for extended range and larger coverage

• Pre-configure channels for sub-teams, such as lighting or sound

• Integrate UltraLITE with other production gear like cameras and wireless audio systems

• Keep spare batteries ready for uninterrupted communication during long shoots
