Goodwill becomes automatic
Anyone who cannot show anything eventually stops checking. Paying becomes the standard route, and the amount per case rises with the level of expectation.
Multiple camera angles and ANPR record the condition of every vehicle with a timestamp. At the next damage claim you have the image in seconds.
At a glance
Starting point
“Your wash scratched my paintwork.” That sentence comes up in every business, and some of these claims are justified. But the matter is rarely decided on the law; it is decided on who can show what. Was the scratch already there? Was the vehicle positioned on entry the way the customer describes? Anyone without an answer is structurally in the weaker position in the discussion — even when the wash ran flawlessly.
In practice the way out is almost always the same: you pay. Not out of conviction, but because a goodwill payment is settled faster than a dispute. That is a commercially understandable decision — and precisely why it adds up over the year without ever appearing in any analysis.
Anyone who cannot show anything eventually stops checking. Paying becomes the standard route, and the amount per case rises with the level of expectation.
Follow-up questions, phone calls, photos to send on, the insurer to involve. Every claim ties up hours that are missing elsewhere in the business.
Without documentation you treat both the same. That loses you money on the unjustified cases — and the justified ones escape your notice, even though they can point to a technical problem with your wash.
Photographic documentation changes only one thing about this — but it is the decisive one: it moves the conversation from assertion to evidence. When the operator is liable and when the customer is, is set out in our guide Damage in the car wash: who is liable? (in German) .
Process
Four fixed cameras are positioned so that together they show the vehicle at the entrance from behind, from the front, at an angle from the side and from above. The system starts recording by itself as soon as a vehicle enters the capture area. Nobody has to press a button, and nobody has to remember.
Image recognition reads the number plate from the image and attaches it to the record along with the date and time. If a plate is not read reliably, the record is still stored in full and can be found by time.
If a customer reports damage days later, you enter the plate or the time window and see the condition of the vehicle at the entrance — as long as the record falls within your retention period.
In daily operation
The camera does not make your wash safer. It changes how a damage claim proceeds — and that is the only point on which the investment is decided.
Instead of “that wasn't there before” against “that was already there”, there is a timestamped record. Some claims are settled in the first conversation as a result — and you settle the justified ones faster, because you know the condition.
Enter the plate, open the record. Without a system, the same task means going through till receipts, asking staff, collecting phone photos — and still not being able to show anything at the end.
If claims cluster around one vehicle type or one time of day, that points to a technical problem with your wash. Without documentation that signal stays invisible, because every case is negotiated on its own and then forgotten.
We supply the data processing agreement, the data protection impact assessment and the description of the technical and organisational measures. You remain the controller — but you are not starting from a blank page.
Scope
Is this the right system for you? Vehicle documentation is right for you if you need an image of the condition on entry when damage claims come in and today you pay for lack of evidence. If instead you want to prevent the collision inside the tunnel, vehicle tracking is the better fit. And if you want to handle, answer and file the claims afterwards — case file, signature, reply letter — that is the cloud platform. The camera supplies the evidence; it does not manage it.
Your calculation
We do not know of any reliable industry average for damage claims at tunnel car washes, and we are not going to invent one. The fields are pre-filled so you can see how the calculation works — none of these values comes from a survey. Overwrite them.
Your assumption. If you do not know this figure, it is the first one worth recording — regardless of any system.
Not just the credit note: repair or goodwill payment, your handling time and, in a dispute, the excess, taken together.
Your assumption — and the figure that dominates the result. It depends on how quickly your customers report damage.
The starting value is our entry price for one capture point.
As long as this field is at 0, the tool is showing you a result that is too favourable. Enter an amount or ask us for it before you calculate — we will give it to you over the phone even without a quote.
damage costs avoided per year
What this calculation is — and what it is not. The calculator multiplies three values you set yourself: damage costs avoided per year = cases × rejection rate × average cost per case. The running costs you assume are deducted from that; the one-off investment is divided by the remaining monthly amount. There is nothing more behind it, and that is deliberate.
Not included are: possible effects on your insurance premium, the work for the data protection documentation on your side, and damage your wash actually caused — you pay for that with or without a camera. Also not included is the time you spend handling a case; that is calculated by the tool on the page for the cloud platform. Do not stack the two results — it is the same case seen from two angles.
Pricing
The entry point is €5,000 excl. VAT for a system at one capture point. On top of that comes a monthly amount for running the system and support. What your site costs specifically depends mainly on how many entrances are to be covered and how the cable routes to the equipment room run. We state the exact amount after a short conversation — in writing, with every component itemised.
Cameras, brackets, network equipment and the computer on which recognition and storage run. The number of cameras depends on the angles you want to cover at each capture point.
Installation on site, cabling, alignment of each individual camera and commissioning by us. Alignment determines image quality — it is set on site, not in the factory.
Software updates, security updates, data backup and a contact for faults. The figure depends on scope and is itemised in the quote — it starts on successful commissioning, not when you order.
Does this fit?
The system is added to existing installations. It assumes no particular wash manufacturer and does not intervene in your controller for capture.
| Step | When |
|---|---|
| Initial call by phone — entrances, number of capture points, existing infrastructure | free of charge |
| Site visit — mounting points, cable routes to the equipment room, lighting after dark | before the quote |
| Written quote with every component itemised | after the site visit |
| Installation — the date is set so that your business can keep running | 3 to 6 weeks after the deposit |
| Acceptance and briefing. From here capture is live and the monthly amount starts | on the installation day |
Existing cameras can occasionally be reused if position, viewing angle and network connection are suitable. Whether that applies to you is something we see at the site visit — we cannot promise it beforehand.
Your data
A number plate can be traced to a keeper. That is why we treat the footage the way personal data has to be treated — and not the way that would be technically most convenient.
This website too. It runs without trackers and without a cookie banner. That is a deliberate choice — anyone who takes other people's data seriously should start with their own visitors. What applies legally to CCTV is set out in our guide CCTV at the car wash and the GDPR .
Critical questions
Yes, under clear conditions. Processing is normally based on legitimate interest under Article 6(1)(f) GDPR — securing evidence for damage claims is a recognised purpose. For that you need a documented legitimate interests assessment, visible signage before the monitored area, an entry in your record of processing activities, a retention and deletion policy with specific periods, and a data processing agreement with us. We supply the documents for this. You remain the controller within the meaning of the regulation — we cannot take the obligation off your hands, but we can take almost all of the work. What we do not provide: legal advice on individual cases. If the situation is sensitive, involve your data protection officer or a solicitor.
You set the period, not us, and it belongs in your retention and deletion policy. Periods of a few days up to around two weeks are common and defensible to supervisory authorities, depending on your legitimate interests assessment. Blanket long-term storage “just in case” is not permitted, and we do not set it up.
That leads to a limitation we would rather name here than later: if your customers typically report damage only after several weeks, the system no longer documents those cases. So before you invest, check how old your claims are on average — that determines the value more than any technical specification.
In darkness the result depends on the lighting. That is why we look at the lighting conditions at your entrance before quoting and include additional lighting where it is needed — better in the quote than in a complaint. Rain costs image sharpness but does not prevent capture; water droplets on the lens are a bigger problem than rain in the air, which is why the cameras are mounted with weather protection and facing away from the prevailing wind.
To be straightforward: in heavy snowfall, dense fog and with a snow-covered plate, automatic recognition can fail. The image is still recorded and can be found by time — so the evidence of the vehicle's condition remains, only the convenient route via the plate search is unavailable for that record.
That is precisely why we will not quote you a recognition rate in per cent without having seen your entrance: any such figure depends on lighting, approach angle and vehicle mix, and without those details it would be an assertion. What we can say: German and the common European plate formats are read reliably. Heavily soiled, bent, partly obscured or unusually styled plates can fail. What matters is what happens then: the record stays fully stored, you find it by date and time and you see the vehicle. The photographic record — the actual purpose of the system — does not depend on the recognition rate.
Access is password-protected and only possible with server access on site. You decide who gets the password; we recommend keeping that group small and naming them in your retention and deletion policy. As for us: we access the system for maintenance and fault clearance — that is why the data processing agreement exists, which governs and limits exactly that. A reason to look at your footage only arises if you call us in about an image problem. If you want to restrict remote access, say so in the initial call — we will set it up that way, and you accept longer response times for faults in return.
Not as a blanket answer, and anyone who promises you otherwise without asking does not know your point-of-sale system. Whether a connection is possible depends on whether your system has a documented interface or whether the data can be extracted cleanly some other way. Tell us the manufacturer and version in the initial call and we will tell you what is possible — including if the answer is that it is not. Important for your planning: vehicle documentation works entirely without this connection. It is an extension, not a prerequisite, and is costed as a separate item.
From live operation
A single record, as the system files it automatically for every vehicle: four angles in one view, with date and time in the image. We have obscured the number plate as well as brand and location markings for this publication.
Date and time are written permanently into the image and are therefore part of every record. We do not claim tamper-proof evidence that would stand up in court — in practice this is about being able to show the customer an image, not about winning an expert opinion.
Other systems
The record proves the condition before the wash. Collision protection makes sure there is nothing to prove inside the tunnel: LiDAR measures the gaps continuously and stops the conveyor before vehicles meet.

Next step
For a solid quote we initially need just three things from you. We clarify the rest at the site visit.
You speak directly to the developer and owner, not to a call centre. The initial call costs nothing and commits you to nothing — if vehicle documentation offers your business little, we will tell you in the same conversation.
