Every production depends on communication that works correctly the first time.

This applies to everything from a one-day corporate video shoot to a large live event or multi-week film production.

A missed cue, delayed equipment movement or communication failure can affect the entire production schedule. In some situations, the moment cannot simply be repeated because the audience, location, performers or technical sequence may no longer be available.

That is why walkie-talkies remain standard communication equipment even as more specialised wireless intercom systems have become available.

Why Productions Still Use Standard Two-Way Radios

Full-duplex wireless intercom systems are useful for core team members who require continuous, two-way communication.

These may include:

  • Directors
  • Camera teams
  • Sound departments
  • Technical directors
  • Stage managers
  • Production control staff

However, full-duplex systems are not always necessary or practical for every crew member.

The wider production team may only need occasional but reliable push-to-talk communication.

This can include:

  • Grips
  • Runners
  • Security staff
  • Parking coordinators
  • Location assistants
  • Background coordinators
  • Catering supervisors
  • Transport teams

Equipping an entire 50-person crew with specialised intercom headsets may be expensive and unnecessary.

Many productions therefore use a layered approach:

  • Wireless intercoms for the core creative and technical team
  • Standard push-to-talk radios for the wider crew

This provides the right level of communication for each role without overcomplicating the system.

Where Walkie-Talkies Are Used on a Production

Assistant directors

Assistant directors are among the most radio-dependent people on a film set.

They may use radios to coordinate:

  • Scene readiness
  • Department checks
  • Performer movement
  • Background actors
  • Location access
  • Camera preparation
  • Sound readiness
  • “Rolling” and “cut” cues
  • Lunch and schedule changes

The assistant-directing team often acts as the communication link between multiple departments.

Reliable radios allow instructions to reach a large crew quickly.

Locations and security

Location teams manage access, logistics and communication around the shoot site.

Their radio responsibilities may include:

  • Controlling access points
  • Coordinating vehicle arrival
  • Managing public areas
  • Monitoring the perimeter
  • Directing crew parking
  • Handling location restrictions
  • Coordinating security staff
  • Managing crowd movement

This is particularly important for location shoots in public or semi-public spaces.

Security teams can also use radios to report incidents without leaving their assigned position.

Grip and electric departments

Grip and electric teams regularly move heavy equipment and modify the technical setup between scenes.

Radios can support:

  • Equipment movement
  • Lighting changes
  • Cable coordination
  • Rigging adjustments
  • Stand positioning
  • Generator requirements
  • Safety communication
  • Confirmation that a setup is ready

Fast communication helps reduce the time required to reset a location between shots.

Background and extras coordination

Productions involving large numbers of background performers require organised communication.

Radio use may include:

  • Calling groups to set
  • Moving performers between holding and shooting areas
  • Coordinating costumes and makeup
  • Confirming readiness
  • Managing crowd scenes
  • Communicating schedule changes
  • Handling transport and meals

Directing dozens or hundreds of people without dependable communication can create significant delays.

Live-event stage management

Live productions depend on precise timing because cues cannot be stopped and repeated easily.

Stage managers and support teams may use radios to coordinate:

  • Performer entrances
  • Vendor timing
  • Backstage movement
  • Security
  • Hospitality
  • Technical support
  • Equipment changes
  • Emergency response
  • Audience management

Radios allow support teams across a large venue to receive instructions immediately.

What Production Crews Need From Their Radios

Discreet and comfortable earpieces

Crew members working close to the camera or audience may need communication equipment that is not visually distracting.

Discreet earpieces can help:

  • Keep radio audio private
  • Prevent sound from affecting a recording
  • Reduce visible equipment
  • Support communication near performers
  • Avoid distracting an audience
  • Improve clarity in noisy environments

The earpiece should remain comfortable during long shooting days.

Enough radios with spare capacity

Radios can be lost, damaged or returned with weak batteries during production.

Experienced production teams often maintain spare capacity above the expected crew requirement.

A reserve of approximately 10–15% above the planned allocation may help cover:

  • Damaged equipment
  • Lost units
  • Unexpected crew additions
  • Battery problems
  • Additional security
  • Background coordination
  • Last-minute location changes

The exact quantity depends on production size and risk.

Clear audio in noisy locations

Film sets and live events may include:

  • Music
  • Crowds
  • Generators
  • Vehicles
  • Special effects
  • Construction activity
  • Outdoor noise
  • Stage audio systems

Noise-cancelling audio and suitable earpieces can help users understand messages correctly.

This is particularly important during live productions where a missed instruction may affect the programme immediately.

Simple channel management

Production crews change frequently, and many users may be unfamiliar with the specific radio model.

The system should be simple enough to distribute with minimal training.

Channel planning may separate:

  • Production
  • Assistant directors
  • Locations
  • Security
  • Technical departments
  • Transport
  • Background coordination
  • Emergency communication

Too many complicated controls can slow deployment and create user errors.

Standard Radios and Wireless Intercoms

Walkie-talkies and wireless intercom systems serve different communication needs.

Standard two-way radios

These generally provide half-duplex push-to-talk communication.

Only one person on the channel speaks at a time.

They are suitable for:

  • Wider crew communication
  • Security
  • Locations
  • Runners
  • Parking
  • Transport
  • Background coordination
  • Support teams

Full-duplex wireless intercoms

These allow users to communicate more naturally and may support simultaneous conversation.

They are useful for:

  • Directors
  • Camera teams
  • Sound teams
  • Technical directors
  • Stage management
  • Production control

The most efficient productions often use both systems as separate communication layers.

They are normally not placed on the same channel because they operate differently.

Renting or Owning Radios for Production Work

Many productions rent radios for individual projects.

Renting may be practical when:

  • The shoot is a one-off project
  • Crew size changes significantly
  • The production duration is short
  • A large fleet is required temporarily
  • The company does not want to maintain equipment
  • Different locations require different setups

Owning may be more practical when:

  • The production company works regularly
  • Projects have short preparation periods
  • The same core team uses the equipment
  • Rental administration creates delays
  • Consistent equipment is preferred
  • Radios are required for more than roughly eight to ten productions each year

The actual cost crossover depends on rental rates, equipment quantity and maintenance expenses.

Some production companies own a core fleet and rent extra units when the crew expands.

Planning Radio Quantities Around Production Phases

Radio requirements may change significantly during a project.

Pre-production and preparation

A smaller number of radios may be needed for:

  • Location surveys
  • Technical preparation
  • Security planning
  • Equipment loading
  • Construction and set preparation

Principal photography or live production

This phase generally needs the largest allocation.

Additional users may include:

  • Full assistant-directing teams
  • Camera and sound departments
  • Locations
  • Security
  • Transport
  • Background coordinators
  • Production assistants
  • Technical crew

Wrap and dismantling

The radio requirement may decrease as departments leave and equipment is packed.

Planning quantities around these phases can reduce rental costs.

It may be unnecessary to rent the maximum number of radios for the entire project if peak staffing only occurs during principal photography.

Building a Production Channel Plan

A written channel plan helps avoid confusion.

A possible structure may include:

ChannelTeamMain purpose
Channel 1Production and AD teamOverall set coordination
Channel 2Locations and securityAccess and perimeter management
Channel 3Grip and electricEquipment and setup coordination
Channel 4Transport and parkingVehicles and movement
Channel 5Background coordinationExtras and holding areas
Channel 6Emergency or supervisorsUrgent escalation

The exact structure depends on the size and complexity of the production.

A small shoot may need only one or two channels, while a major production may require several department-specific groups.

Radio Distribution and Tracking

Production radios should be issued through a controlled process.

A distribution list may record:

  • Radio number
  • User name
  • Department
  • Channel assignment
  • Earpiece issued
  • Battery issued
  • Time collected
  • Time returned
  • Damage or loss

Labelling radios makes them easier to track.

Production teams may also use colour-coded accessories for different departments.

This helps reduce loss and makes end-of-day collection faster.

Preparing Radios Before the Shoot

Before distribution, every radio should be:

  • Fully charged
  • Correctly programmed
  • Labelled
  • Tested
  • Assigned to the right channel
  • Paired with the correct earpiece
  • Checked for physical damage
  • Logged in the equipment list

Spare radios and batteries should be kept in an accessible location.

The production office or communication coordinator should know who is responsible for replacements.

Radio Etiquette on Set

A busy radio channel can become difficult to use.

Useful etiquette includes:

  • Identify yourself and the intended recipient
  • Keep messages brief
  • Use agreed call signs
  • Avoid unnecessary conversations
  • Confirm critical instructions
  • Wait until the channel is clear
  • Pause briefly after pressing push-to-talk
  • Reserve emergency terminology for genuine emergencies
  • Follow radio-silence instructions during recording
  • Avoid transmitting sensitive information unnecessarily

Assistant directors or production managers may request radio silence during critical moments.

Outdoor and Location-Shoot Considerations

Outdoor locations may require stronger weather protection and wider coverage.

The radio setup should account for:

  • Rain
  • Dust
  • Heat
  • Cold
  • Large distances
  • Buildings or terrain
  • Public roads
  • Remote parking
  • Base camps
  • Separate shooting areas

A temporary repeater may be needed when teams are distributed across a large location.

Coverage should be tested during the technical survey rather than on the first shooting day.

Live-Music and High-Noise Events

Concerts and live entertainment create extreme audio conditions.

Standard radio speakers may be difficult to hear.

Suitable equipment may include:

  • Noise-cancelling headsets
  • In-ear monitors where appropriate
  • Remote speaker microphones
  • Hearing-protection-compatible accessories
  • High-output audio
  • Vibration alerts

The communication setup should be tested while the sound system is operating at realistic levels.

How Many Radios Does a Film Production Need?

There is no fixed number because crew sizes vary greatly.

A practical starting point may include one radio for:

  • Each department head
  • Assistant directors
  • Location managers
  • Security supervisors
  • Transport coordinators
  • Background coordinators
  • Key production assistants

A mid-sized production may require approximately 15–25 units.

Large productions involving extensive locations, security or background performers may require significantly more.

Spare radios should be added beyond the planned allocation.

Lost and Damaged Radio Procedures

Production environments are demanding, and lost or damaged equipment is common enough to require a plan.

The production should define:

  • Who reports a missing radio
  • How replacements are issued
  • How equipment is tracked
  • Who pays rental damage charges
  • How damaged units are isolated
  • How end-of-day checks are completed

For rented equipment, loss and damage terms should be reviewed before the shoot begins.

Frequently Asked Questions

Why do film productions still use walkie-talkies?

They provide simple, immediate and reliable group communication for a large crew.

They are also easier and more economical to distribute widely than full-duplex intercom systems.

How many radios does a typical film shoot need?

A mid-sized shoot may use approximately 15–25 radios, but the number depends on crew size, departments, locations and background requirements.

Do outdoor productions need different radios?

Outdoor shoots may need stronger weather resistance, longer range and possibly a temporary repeater.

Can walkie-talkies and wireless intercoms use the same channel?

Generally, no.

They are normally operated as separate systems because full-duplex intercoms and half-duplex radios function differently.

How many spare radios should a production maintain?

Experienced teams may plan roughly 10–15% spare capacity above their normal allocation, depending on project risk and equipment availability.

Should every crew member receive a radio?

Not necessarily.

Radios are usually prioritised for department heads, coordinators, security, transport and roles requiring immediate communication.

Are discreet earpieces necessary?

They are particularly useful for crew working near the camera, performers or live audiences where radio audio and visible equipment must be minimised.

Is renting better than owning?

Renting suits one-off or variable productions.

Production companies running frequent projects may find ownership more economical over time.

Communication That Keeps Production Moving

Film sets and live productions depend on timing, coordination and reliable handovers.

A missed message can delay equipment movement, confuse performers, interrupt an event or affect the production schedule.

The most effective communication systems combine:

  • Standard radios for the wider crew
  • Wireless intercoms for the core creative team
  • Discreet earpieces
  • Clear channel planning
  • Spare equipment
  • Coverage testing
  • Controlled distribution
  • Simple radio etiquette

When these elements are planned properly, production teams can communicate quickly without creating unnecessary complexity.
