Recording
your employees

You can, with conditions, and none of them is expensive. The first, and the one most often skipped: inform the workforce and their legal representatives beforehand, expressly. The second allows no nuance: in changing rooms, toilets, staff canteens and rest areas, never, not even if everyone agrees.

The starting point

It's not whether you can, it's whether you told them

Almost every case that goes wrong doesn't fail because of the camera: it fails because of what wasn't said before it went up.

Installing cameras in a workplace is legal. They can be fitted to protect people and property, and also to verify compliance with employment obligations. What isn't optional is informing people beforehand, and that's where almost everything breaks down.

The sign at the entrance covers customers, suppliers and visitors. With the workforce the bar is higher: you need an express, prior notice addressed to the employees and to their legal representatives if there are any, explaining that there are cameras, where, what for and what is done with the footage.

It costs neither money nor time: it's a one-page document, signed or handed over with an acknowledgement of receipt. What costs is not having it, because when a dispute arises (a dismissal, a claim, an inspection) the argument isn't about whether the camera was reasonable, but whether anyone can prove that staff were informed. Without that piece of paper, the recording is worthless.

The rules

Five conditions that must all be met at once

This isn't a list of recommendations: if one fails, the whole thing fails.

01

Inform beforehand, and in writing

The workforce and their representatives. Before switching anything on, not the day after. What matters isn't the format but being able to prove it later.

02

Proportionality: only what's necessary

The camera has to point at what you want to protect. The till, the entrance, the stockroom with expensive goods. A shot that also captures someone's workstation in full for eight hours straight is hard to justify, and it's the first place an installation falls down.

03

Prohibited areas, no exceptions

Changing rooms, toilets, showers, staff canteens and rest rooms. No proportionality argument applies here, and no workforce consent can permit it. It's a hard line.

04

Controlled access to the footage

Who can view the recordings must be decided and limited. Individual passwords, two-factor authentication for remote access and no shared accounts. A recorder with its factory password is as common as it is serious.

05

The same time limit as everything else

Footage from a workplace is deleted like any other: a maximum of one month. Keeping it longer because "they're employees" changes nothing.

Where yes and where no

Typical areas of a business

The corridor camera hardly ever causes trouble. The problems lie at the two ends of this table.

AreaCamera?Nuance
Entrances and perimeterYesThe easiest of all to justify
Stockroom and goods areaYesJustified by the value of what's there
Till or checkoutYesFrame the hands and the counter, not the cashier's face
Corridors and common areasYesMonitoring people passing through, not staying
Individual workstationWith careOnly if there's a specific reason, and with a tight shot
Staff canteen and rest roomNoProhibited, no exceptions
Changing rooms, toilets and showersNoProhibited, no exceptions
Costly mistakes

Four things that get evidence thrown out

They all come to light after an incident, when there's no longer any room to fix them.

01

The secretly installed camera

Putting a secret camera somewhere nobody knew there was surveillance is the costliest mistake. The recording isn't valid as evidence and the matter turns against the business. Using the existing system, which staff were already told about, to prove a specific fact is different: that does stand up.

02

Audio on by default

A lot of equipment ships with the microphone enabled and nobody checks. Recording the conversations of people at work is far more invasive than recording images, and rarely justified. Disabling it is one click on installation day.

03

Shared remote access

A single account with the factory password, known to five people and reachable from the internet. More CCTV footage has leaked through that door than through any other route, and it turns a security system into the main risk.

04

The purpose that wasn't declared

Staff were told the cameras were for security, and then a recording is used for a performance or working-hours issue. Footage can only be used for what you said you'd use it for. If you want both purposes, declare both from the start.

How to get it right

One document, one shot and one password

In short: almost everything that goes wrong with a business installation is fixed before it's switched on, not afterwards.

The notice to the workforce is one page. The sign at the entrance, which covers everyone who doesn't work there, has its own requirements and is short too. Camera angles are decided on installation day, and turning a camera fifteen degrees then takes five minutes; doing it two years later, after someone has complained, costs rather more.

That leaves the part nobody associates with the rules but that causes the most grief: who logs into the recorder and with what password. A system with proper notice, good framing and the factory password is still a serious problem, because the footage exists and you don't control it.

If you have cameras in a workplace and don't know where you stand, the review is short: we look at camera angles, retention period, access and what paperwork exists. We tell you what's fine and what needs changing, and anything that can be fixed by moving things is fixed there and then. It's the same review we carry out as part of IT maintenance for businesses.

Common questions

What people usually ask

Can I put cameras where my staff work?+

Yes, and it's a different situation from monitoring only entrances or the stockroom: here the camera sits alongside someone's daily work for their entire shift, so the room for justification is narrower. Proportionality stops being an abstract principle and becomes the question you have to answer before installing anything: is there a specific reason (a till position, an area with sensitive stock, a history of incidents) that can't be dealt with any other way? If the answer is generic, "to keep an eye on staff", the installation won't stand up. And even if the reason is good, the framing has to be limited to that reason: the camera watching the till doesn't need to see the chair or the locker next to it. The more hours a camera captures the same person at the same workstation, the easier it is for someone to question later whether it was really necessary, so document the reason before switching it on, rather than inventing one afterwards.

Who exactly do I have to inform?+

Every person who will be on camera, whatever their contract: permanent, temporary, interns or subcontractor staff working on your premises. If there's legal workforce representation (a works council or staff delegates), them too, and separately from the individual notice: informing only the works council and assuming it reaches everyone doesn't comply. The notice has to explain what is recorded, where the cameras are, for what purpose and what is done with the footage; saying "there are cameras" isn't enough. Anyone who joins after the installation must be given the same information when they start, rather than assuming they know from the sign or from what colleagues tell them. And when you change something significant (add cameras, change the purpose, switch on audio), the notice is repeated: the one given at the outset doesn't cover what came afterwards.

Where can I never put a camera under any circumstances?+

The prohibited areas aren't just changing rooms and toilets in the strict sense: the same logic extends to any corner staff use to genuinely switch off, even if it isn't labelled that way on the floor plan. A small kitchen where staff eat, a corner with a sofa that serves as an informal break room, a storeroom that's also used for changing clothes: if that's its real function, the camera can't point there even if the space is called a "storage room" in the lease. Nor is it an excuse that the camera is "only there to watch the fire exit" if the shot catches the rest area at an angle: you have to move the camera or mask that part. And if a business shares a building with another and the changing room is shared by both workforces, the prohibition doesn't change because it's a shared space: it's still a private space and still off limits to any camera.

Can I record sound?+

Almost never, and it's worth distinguishing two situations that get confused. A camera with a microphone recording continuously next to a workstation captures entire conversations of people who are simply doing their job, and that rarely has a proportionate justification: it's a far greater intrusion than images alone. It's different with an alarm system that triggers brief audio only on a specific event, such as an out-of-hours intrusion; there the situation changes because there's no continuous recording of work conversations. Many recorders come with the microphone switched on from the factory without anyone having decided so, simply because the equipment comes that way, so check each camera's settings and disable audio unless there's a specific, documented reason to have it on. If you're unsure whether your installation is recording sound without your knowing, it's one of the first things worth checking, and it takes minutes.

I suspect someone is stealing. Can I put up a hidden camera?+

A hidden camera as such (bought and installed to catch a specific person, without the system having existed before or anyone having been told about it) is the most slippery ground in this area, and it isn't a reasonable shortcut even if the suspicion is well founded. What does work is different: if you already have a system that's installed, notified and with known camera angles, you can use those recordings to prove a specific fact without warning in advance that you're going to review that person's footage on that day; that doesn't make the system hidden, because its existence was already known. The line between the two isn't always obvious on the ground, and getting it wrong has serious consequences: the evidence can be thrown out entirely and the spotlight shifts from the suspect to the business that installed the camera. If you're in this situation, before installing anything new or using a recording for a dismissal, that's the moment to consult a specialist, not to improvise.

Can I use the cameras to check punctuality?+

It depends entirely on what you stated when you informed staff, and that's where problems usually arise: many businesses install cameras thinking only about theft or intrusion, inform staff of that, and months later someone has the idea of using them to see who arrives late. That use isn't covered by the original notice, so the footage can't justify a disciplinary measure for lateness even if it shows the exact time of arrival. If time-keeping really is an aim, the right thing is to state it from the outset alongside security, not to add it along the way when it's needed for a particular case: that shows, and it weakens any later use. Besides, combining both purposes on the same camera tends to produce wider shots than pure security needs, so consider whether it's really necessary, or whether a dedicated clocking-in system, which records nobody's image, does the same job with less friction and less risk.

Can I view the cameras on my phone when I'm not there?+

Yes, and the problem is almost never the app but who else has access to it. Over time, accounts build up that should no longer be active: an employee who left the business, an installer who commissioned the system two years ago and never had their access removed, a partner who's no longer involved in the business. Each of those accounts is an open door onto footage of people at work, and nobody reviews the list until there's a problem. It's worth regularly clearing out who has remote access, not just protecting it with a strong password and two-factor authentication when it's set up. It's also worth keeping a simple log of who logs in and when, because if you ever have to show that only the right people accessed it, that log is the proof; without it, the answer to "who has seen this footage?" is a guess, and that counts against the business.

What if the workforce objects?+

Consent not being the legal basis doesn't mean the workforce's opinion can simply be ignored: it's valuable information about how the installation is being experienced, and it's worth taking seriously before it turns into a formal dispute. First, listen to the specific reason for the objection, because it's almost never "I don't want cameras in general" but something more precise: a shot that's seen as excessive, a camera installed without the expected notice, doubts about who sees the footage. Reviewing that exact point is usually enough to resolve the conflict without touching the installation as a whole. If there's legal workforce representation, they're the natural counterpart for this conversation, and keeping a record that it was discussed and what was agreed protects both sides if the matter comes up again later. Simply ignoring the objection, on the other hand, usually ends in a formal complaint that forces you to review the same thing, but in worse circumstances.
