Camera On or Off? 9 Studies Reveal When Video Actually Matters [2026]

Last month, a product manager I coach received her first HR complaint in a decade-long career. Her offense? Keeping her camera off during team meetings.

Meanwhile, a VP of Engineering at another company told me his best performers had started declining meeting invites entirely. When he dug into why, the answer was consistent: "I can't handle another day of performing for the camera."

The "cameras on" debate has become one of the most contentious issues in modern workplace culture. Some companies mandate video as proof of engagement. Others have declared camera-optional as the enlightened default. Both sides claim the research supports them.

So I did what any data nerd would do: I analyzed 9 major studies to find out what the evidence actually shows. This includes Stanford's Virtual Human Interaction Lab research on Zoom fatigue, a Vyopta study tracking 450,000 employees across 40 million meetings, 2025 findings from the European Journal of Social Psychology, and surveys from Korn Ferry, Owl Labs, and others.

Here's the uncomfortable truth: both sides are partially right, and both are partially wrong.

The answer isn't "always on" or "always off." It depends on four factors: meeting type, your role in the meeting, individual circumstances, and what your organization actually needs.

This guide gives you the data to make informed decisions—whether you're an individual contributor wondering what's appropriate, a manager trying to set reasonable expectations, or an executive building policy.

The Case for Cameras On

Let's start with the pro-camera research, because there's real data here that the "cameras are evil" crowd tends to ignore.

The Numbers That Support Video

These aren't trivial findings. When three-quarters of professionals believe cameras-off is viewed negatively, that perception becomes reality—fair or not.

Why Cameras Actually Help (Sometimes)

Nonverbal communication carries meaning that audio can't.

When someone says "that sounds fine" while visibly grimacing, you catch the disconnect. When a quiet team member lights up at an idea, you notice and draw them out. These micro-signals shape better decisions.

A 2021 study found that employees with cameras on contributed more during meetings than those with cameras off. Not because cameras magically create engagement, but because visual presence creates accountability—both to participate and to notice when others need space to speak.

Relationship building requires faces.

I've watched remote teams struggle for months to build trust, then bond in hours during an offsite. Faces matter for forming human connection. Video isn't the same as in-person, but it's closer than voices alone.

For first meetings—new colleagues, new clients, new hires—cameras provide the visual information humans have evolved to use when assessing whether someone is trustworthy, competent, and likeable.

The retention correlation is real (though misunderstood).

The Vyopta finding deserves attention: employees who left their organization within a year had cameras on in only 18.4% of small group meetings, compared to 32.5% for employees who stayed.

But here's the critical interpretation most miss: this doesn't mean turning cameras on prevents attrition. It means camera behavior is a signal—a leading indicator that someone is disengaging. We'll dig into this more later.

The Case Against Mandatory Cameras

Now for the research that should make any "cameras always on" policy feel deeply uncomfortable.

Stanford's Zoom Fatigue Framework

Jeremy Bailenson, founding director of Stanford's Virtual Human Interaction Lab, has spent over two decades studying virtual communication. His peer-reviewed research identifies four mechanisms that make video calls uniquely exhausting:

1. Excessive close-up eye gaze

In person, we rarely maintain continuous eye contact. It's uncomfortable—even threatening. On video, you're staring at multiple faces simultaneously, and they're all staring back. Your nervous system interprets this as hyper-arousing.

"We know from a physiological standpoint that if somebody is really close up to you and they're looking at you, you're about to mate or you're about to fight, from an evolutionary standpoint," Bailenson explains.

2. Self-view cognitive load

Seeing yourself on screen creates constant self-evaluation. It's cognitively identical to working while someone holds a mirror in front of your face all day.

"In the real world, if somebody was following you around with a mirror constantly—so that while you were talking to people, making decisions, giving feedback, getting feedback—you were seeing yourself in a mirror, that would just be crazy," Bailenson says. "No one would ever consider that."

Research shows this self-view effect is particularly pronounced for women and people with social anxiety. The mirror triggers continuous self-criticism that compounds throughout the day.

3. Physical confinement

Video meetings lock you in place. You can pace during a phone call. You're stuck in frame during video.

"There's growing research that says when people are moving, they're performing better cognitively," Bailenson notes. The tight fixed angle of video reduces the range of acceptable movement far more than even in-person meetings.

4. Nonverbal production and interpretation overload

In person, body language flows automatically. On video, you must consciously produce appropriate nonverbal cues (nodding, expressions, posture) while simultaneously working harder to interpret everyone else's limited visual information.

This dual cognitive load—performing AND decoding—depletes working memory faster than in-person interaction.

The Gender and Demographic Gap

Here's where the data gets uncomfortable for "cameras always on" advocates:

When one in seven women report feeling "very" to "extremely" fatigued after video calls—compared to one in twenty men—a mandatory cameras-on policy isn't neutral. It's a policy that disproportionately burdens specific groups.

The Stanford team found that what drove this gender gap was "self-focused attention"—the heightened awareness of how you appear that the self-view triggers. Women reported significantly higher self-focused attention during video calls.

New employees face a compounded challenge: they have less social capital to push back on meeting norms while simultaneously being more affected by the fatigue those norms create.

What 82.9% of Professionals Already Know

In survey after survey, the same finding emerges: 82.9% of professionals believe not all video meetings require video.

This isn't anti-video sentiment. It's recognition that cameras are a tool with appropriate and inappropriate uses—not a universal requirement that signals professionalism.

The Retention Paradox: Why the Vyopta Data Doesn't Mean What You Think

Let's return to that striking Vyopta finding: employees who quit had cameras on 18.4% of the time; employees who stayed, 32.5%.

Some managers see this and conclude: "Force cameras on to improve retention." That's backwards.

Camera Behavior Is a Symptom, Not a Cause

Think about what it means when someone stops turning their camera on:

• They're already disengaged and don't want to perform
• They're overwhelmed and conserving cognitive resources
• They've mentally checked out of the team
• They're job searching during meetings

Turning cameras off doesn't cause these states. It reflects them.

Mandating cameras-on is like requiring employees to smile more because happy employees smile. You get performative compliance, not genuine engagement. The underlying disengagement—the thing that actually predicts attrition—remains unaddressed.

The Useful Takeaway

Camera behavior is a valuable leading indicator for managers. If a previously camera-on team member starts consistently opting out, that's a signal worth a private conversation. Not "why aren't you on camera?" but "how are you doing? What's on your plate?"

The Vyopta researchers made this point themselves: the value is in identifying potential attrition signals early—not in mandating video as a retention strategy.

The Accessibility Factor Most Guides Ignore

Here's where the "cameras-on means engagement" argument falls apart completely: it assumes a neurotypical baseline that doesn't reflect the actual workforce.

Why Camera Mandates Can Be Ableist

For people with ADHD: Self-monitoring while on camera depletes already-limited executive function. The constant awareness of "am I making appropriate expressions? Is my posture okay? Did I just space out visibly?" adds cognitive overhead that directly competes with following the meeting content.

Many people with ADHD focus better when they can fidget, move, or look away—behaviors that feel inappropriate on camera but support actual attention.

For autistic individuals: Eye contact is often uncomfortable or actively distressing. The pressure to maintain "appropriate" expressions means spending energy on masking rather than contribution.

One Zoom employee who is autistic and has ADHD describes it this way: having cameras on for all meetings creates "a feeling of cognitive or social overload."

For people with anxiety disorders: The self-view triggers continuous self-evaluation and criticism. Social anxiety compounds when you can see yourself being watched by a grid of faces.

For those with physical disabilities: Some people need to move, stretch, or position themselves in ways that don't fit neatly in a camera frame. Chronic pain conditions may require changing positions frequently.

The Core Problem with Mandatory Policies

"Requiring cameras to be on as a demonstration of 'being present' or 'paying attention' is an inherently ableist requirement," writes Victoria Tretis, a neurodiversity workplace consultant.

"This implies that the only way a person can demonstrate their focus or care is via eye contact, facial expression, sitting still, and maintaining a 'presentable' appearance—which is not true for many disabled people, especially those with invisible disabilities."

The accommodation problem is real: someone shouldn't have to disclose ADHD, autism, or anxiety to their manager just to turn their camera off without judgment.

The Neurodiversity-Inclusive Approach

The solution isn't complicated: cameras encouraged, not required, with explicit permission to opt out without explanation.

This protects people who need accommodation without requiring disclosure. It also benefits the large percentage of neurotypical employees who simply focus better with cameras off in certain contexts.

The Decision Framework: When to Actually Turn Your Camera On

Enough theory. Here's a practical framework based on what the research actually supports.

Camera ON: High-Value Situations

In these contexts, cameras genuinely add value that exceeds their cognitive cost. The visual information serves the meeting's purpose.

Camera OFF: Acceptable and Often Better

In these contexts, cameras add cognitive load without proportional benefit. The meeting outcome won't change based on whether attendees can see each other.

The Quick Decision Test

Before your next meeting, ask:

1. Am I meeting someone new? → Camera on
2. Am I presenting or leading discussion? → Camera on
3. Is this a small group where I'll actively participate? → Camera encouraged
4. Is this a large meeting where I'm mostly listening? → Camera optional
5. Am I on meeting #4+ today? → Camera off is self-care

When in doubt, match the meeting organizer's camera status, or simply ask: "Is this a cameras-on meeting?"

Building a Camera Policy That Actually Works

If you're a manager or executive setting team norms, here's how to do it without the problems we've discussed.

Sample Policy Language

Video Meeting Guidelines

Video is encouraged but not required for most meetings. We trust team members to make appropriate choices based on meeting context and personal circumstances.

Cameras on expected when:

• You're presenting, facilitating, or leading discussion
• First meetings with new colleagues, clients, or partners
• The meeting organizer explicitly requests video with a stated reason

Cameras off is always acceptable:

• For personal circumstances without explanation required
• During listen-only portions of larger meetings
• When you need to manage back-to-back meeting fatigue

We don't track or evaluate camera usage. We evaluate contribution and outcomes.

Implementation Principles

Leaders must model camera-off themselves. If managers are always on camera and say "it's optional," the team reads that as "optional but noticed." Take camera-off days visibly.

Never single out individuals. "Sarah, could you turn your camera on?" in a meeting is a public callout. If you have concerns about someone's engagement, address it privately and holistically.

Measure outcomes, not compliance. Did the meeting accomplish its purpose? Did everyone who needed to contribute get heard? Those questions matter. Camera usage doesn't.

Normalize the ask. Make it standard for meeting invites to specify whether cameras are expected. Remove the guesswork.

Companies Getting It Right

Citigroup and Dell implemented "No Zoom Fridays" to combat video fatigue systemically rather than individually.

GitLab operates async-first, treating video meetings as the exception requiring justification—not the default requiring an opt-out.

SAP encourages cameras but frames it as "managers should model it" rather than "employees must comply."

Practical Tips for Either Choice

If You Keep Your Camera On

Hide self-view immediately. This single change removes the biggest fatigue driver. In Zoom: right-click your video → "Hide Self View." In Teams: right-click → "Hide for me." Do this in your first meeting of the day and forget about it.

Use speaker view, not gallery. Seeing 25 faces staring at you triggers the threat response. Seeing one speaker is manageable.

Position your camera at eye level. Reduces neck strain and creates more natural "eye contact" with the lens.

Take audio-only breaks in long sessions. Turn camera off for 5-10 minutes mid-meeting if it's running long. No one will remember; your brain will thank you.

Look at the camera lens when speaking, the screen when listening. This is less natural but reduces the sustained eye-gaze exhaustion.

If You Keep Your Camera Off

Contribute verbally more frequently. Without visual presence, audio presence matters more. Speak up, even briefly, to stay engaged and visible.

Use reactions and chat actively. Thumbs up, raised hands, and chat comments signal engagement when your face doesn't.

Turn camera on briefly when making key points. A hybrid approach—camera on for your contributions, off otherwise—can work well.

Don't apologize. "Sorry my camera's off" suggests you're doing something wrong. You're not. Just participate fully in whatever mode you're in.

What the Data Actually Tells Us

After analyzing nine major studies and tracking this issue across dozens of organizations, here's what I can confidently say:

Cameras on doesn't equal engagement. You can be physically present on video and mentally elsewhere. You can be camera-off and deeply focused on the discussion.

Mandatory camera policies hurt specific groups disproportionately. Women, newer employees, introverts, and neurodivergent individuals bear higher costs from video fatigue than others.

Camera behavior signals engagement levels but doesn't create them. Forcing cameras on doesn't make people more engaged—it makes them more exhausted.

Visual presence adds value in specific contexts. New relationships, small discussions, complex conversations—these benefit from faces. Large broadcasts and routine syncs don't.

The best policy is explicit flexibility. State when cameras add value. Give blanket permission to opt out otherwise. Never tie camera usage to performance evaluation.

The goal isn't maximum camera time. It's maximum meeting effectiveness with sustainable cognitive load.

Your team can't do their best work if they're exhausted from performing for the camera all day. And they can't build relationships if they never see each other's faces. Both are true. The answer is intentionality—not mandates.
