How to Choose the Right Camera Solution for Your All-in-One Display

In today’s interactive display market, the camera is no longer a simple accessory. It has become a core communication component that directly affects video quality, audio pickup, user experience, and even how “intelligent” an all-in-one display feels.

For buyers, distributors, and system integrators, one question comes up again and again:

Should I choose a built-in camera or an external camera for an interactive display?

And if an external camera is required:

  • Is a standard 4K camera enough?
  • When does a high-end PTZ camera actually make sense?
  • Can cameras be upgraded later?
  • And most importantly: Is AI integration possible?

As a display manufacturer with 10+ years of R&D experience in interactive display systems, Qtenboard has served 5,000+ enterprises and educational institutions worldwide, holding 20+ patents in camera AI tracking algorithms and audio-visual integration. We design interactive displays with both built-in and external camera solutions, covering entry-level to professional-grade applications, with products compliant with CE (EU), FCC (US), and CCC (China) certifications.

This guide breaks everything down clearly — not just what the cameras are, but how to choose the right one for your real-world scenario, backed by real project data and industry best practices.


What Is a Built-in Camera on an Interactive Display?

Аbuilt-in camera is integrated directly into the interactive flat panel itself, usually positioned at the top center of the screen.

In most professional interactive displays, including Qtenboard models, the built-in camera typically comes with:

  • Fixed-position wide-angle lens
  • Integrated multi-array microphone system (commonly 8-microphone array)
  • Optimized firmware tuned specifically for conferencing and teaching
  • No external wiring, no extra installation

Why built-in cameras exist

Built-in cameras were created to solve three core problems:

  1. Ease of use – no setup, no configuration, no compatibility issues
  2. Clean appearance – no cables, no external devices mounted on walls or brackets
  3. Consistency – stable performance for daily meetings and classrooms

For many buyers, especially in education and corporate meeting rooms, this simplicity is not a “nice-to-have”, but a procurement requirement.


When Does a Built-in Camera Make the Most Sense?

Built-in cameras are ideal when:

1. The usage environment is fixed

  • Классы
  • Small to medium meeting rooms
  • Internal corporate collaboration spaces

In these scenarios, the distance between users and the screen is predictable, and a wide-angle fixed lens works perfectly. A case study of a UK-based primary school shows that deploying 50 interactive displays with built-in cameras cut setup time by 60% compared to external camera alternatives.

2. Ease of deployment matters more than flexibility

Schools, training centers, and large enterprises often need to deploy dozens or hundreds of units. A built-in camera reduces:

  • Installation time
  • After-sales complexity
  • Compatibility risks

A Fortune 500 manufacturing company reported a 40% increase in deployment efficiency and a 2% post-sales issue rate after adopting Qtenboard’s built-in camera displays for its 200+ regional offices.

3. Audio clarity is as important as video

Most built-in camera modules are paired with 8-array microphones, offering:

  • 5-meter pickup range
  • ≥85% noise suppression rate (lab-tested data)
  • Voice clarity optimized for conferencing software (Zoom, Teams, DingTalk)

This makes built-in solutions particularly suitable for hybrid classrooms and daily video meetings.


Limitations of Built-in Cameras (And Why External Cameras Still Matter)

Despite their convenience, built-in cameras are not designed to solve every scenario.

Common limitations include:

  • Fixed angle – no optical zoom, no PTZ movement
  • Limited adaptability for large rooms (e.g., lecture halls, auditoriums)
  • Less suitable for professional broadcasting or recording
  • Difficult to upgrade individually

This is where external cameras become essential.


What Is an External Camera for Interactive Displays?

An external camera is a separate, detachable device connected to the interactive display via USB, HDMI, or LAN.

Qtenboard supports multiple external camera levels, all compliant with regional regulations (GDPR data encryption for EU markets, local warranty service in APAC):

  • Standard 4K USB cameras
  • 4K cameras with remote control
  • High-resolution 11MP cameras
  • Professional-grade PTZ cameras (mid-to-high-end)

This modular approach allows buyers to choose performance based on actual needs, instead of overpaying for features they don’t use. For example, OEM buyers in Southeast Asia often opt for standard 4K cameras to balance cost and performance for SME clients.
