The button camera is so small that it looks like an ordinary shirt button. No visible lens, no blinking LEDs—even upon close inspection, it’s indistinguishable from a real button. The mini camera with live transmission to your phone works without Wi-Fi—even RF scanners won't detect it.

I'm really happy with the set! The camera shows a super sharp image and my mate could read everything perfectly. The earphones really are completely invisible - nobody noticed a thing even though the examiner stood right next to me several times. The sound comes through clear and crisp. The battery easily lasted the full 3 hours. Everything worked straight away with my Samsung. I passed the exam and can only recommend the set!

Honestly, I had zero expectations, but it actually worked. The camera shows a clear image, my helper could read everything easily and talk me through it. The earphones really are completely invisible - even when the examiner was standing right next to me, he didn't notice a thing. The battery lasted the full 3 hours. Delivery arrived within 4 days. I'm really happy and I passed the exam. Can only recommend it!

I was sceptical at first, but the set exceeded all my expectations! The camera delivers a razor-sharp image in 2K, and the earphones are completely invisible - nobody had the slightest idea. Delivery was super fast, everything arrived within a few days. Customer service answered all my questions beforehand and was very helpful and friendly. Marie from the team really took her time and explained everything in detail. The earphone batteries easily lasted 4 hours, and spare batteries were included too - top! My helper could see the image perfectly via Anydesk and talk me through everything. It worked flawlessly. Passed the exam with flying colours! An absolute must-buy for anyone in a similar situation. The value for money is definitely there. Thanks to the Spickprofi team!

I was genuinely panicking before the exam, but with the set everything was relaxed. The camera shows everything clearly and crisply, you can hear the earphones perfectly. My mate sat at home and helped me - nobody noticed. Delivery arrived quickly, everything you need was included. I'd buy it again any day!

Works flawlessly with my Samsung phone

Mini camera works well for exams. At first the app connection was a bit tricky, but after trying a few things everything runs stably. The image of the exam paper shows clearly once the focus is set right. The camera really is tiny, it doesn't stand out at all in the shirt button. For someone who needs help discreetly, this set is very useful. Already recommended it to colleagues.

It worked perfectly! The mini camera was super discreet and I could make out everything clearly during the exam. Top for any exam where you don't want to take any risks. Absolutely recommended!
Translated from German
The mini camera is very small and discreet. Image quality is good and the exam questions are clearly legible. The connection stayed stable the whole time, no dropouts. Operating it makes sense after a short while.

Used it for my German exam, worked great. The camera was clear and discreet, nobody noticed a thing. Very practical and genuinely helpful.
Translated from German
meh, it's ok. camera really needs a lot of light otherwise it goes blurry and out of focus fast
Translated from German
The mini camera really is discreet and delivers a decent image. Definitely practical for exams and easy to use. In low light the quality could be a bit better though, hence a small deduction. Overall I'm happy.
Translated from German
The set genuinely helped me in my exam. The camera is discreet and after a bit of experimenting the image quality is more than good enough to read the questions clearly. I particularly liked the invisible earphone - you barely notice it while wearing it and from the outside it isn't visible at all. The connection was stable, even over several hours. I was a bit nervous at first, but once everything was set up it worked great. All in all a very well thought-out set that delivers exactly what it promises.
Translated from German
The Spick set did a good job in my last exam. The button camera is discreet and delivers a decent image, even if you have to experiment a bit until everything is clearly legible. The mini earphone sits securely in the ear and doesn't stand out at all. Setting it up was a bit tricky at the start, but after a few tests it worked reliably. All in all a worthwhile help, as long as you practise in good time.
Translated from German
The Spick set helped me in my exam and worked well overall. The camera is small and discreet, but you do need to take some time to find the right setting. The earphones are handy too, though it takes a bit of practice before everything runs smoothly. If you prepare properly, the set is definitely a worthwhile support.
Translated from German
The image quality is surprisingly good once you set the focus properly. A bit tricky at first, but with some patience it works great. Ideal for discreet use - clear recommendation!

Your helper sees your exam paper live on his screen. On your shirt, there's just a button.
Sew it on or attach it with the clip. Indistinguishable from a real button, no visible lens, no LED.
Run the cable under your clothes to your phone, plug it in, done. No Wi-Fi, no wireless signal.
From now on, your helper sees your paper live on his screen and controls your phone from home. Keep about 30 to 50 centimetres of distance, and every line stays sharp.
For discreet recordings, the Spickprofi shirt button variant is the strongest choice: It looks like a normal button, has no visible lens and no LEDs. With 2K resolution (2560 × 1440) and live transmission to your phone, it is the best mini camera with live transmission for covert operations - exams, research or covert observation. USB-C plug-and-play, works without Wi-Fi, delivered including step-by-step instructions.
Yes. The connection to the mobile phone runs via USB-C, not a Wi-Fi network. So you can use the camera even in rooms without internet — typically, for example, in examination rooms or while traveling. Since no radio signal is generated, the camera cannot be detected via Wi-Fi or Bluetooth scan.
Yes. The Mini Camera with Audio records audio via your phone's microphone — image and sound are synchronized in the same video file. No separate microphone, no extra equipment needed. The audio quality corresponds to that of your phone, which is more than sufficient for voice recordings in normal environments.
The camera transmits not wirelessly, but directly to your phone via a USB-C cable — so the camera and phone remain connected. Therefore, there is no wireless range between the camera and the phone. The actual distance is created via your phone: Anyone who wants to watch the live stream remotely will receive it via a normal video connection from your phone (e.g., via a video call) — then the range is practically unlimited, as long as mobile network or internet is available.
Mini cameras are legal in Germany – possession and purchase are not restricted. However, there are legal limits regarding their use:
Permitted: Recordings on your own property, gathering evidence with a legitimate interest, recordings with the consent of all parties involved, self-documentation.
Forbidden: Secret video recordings in protected areas (§ 201a StGB), audio recordings of third-party conversations without consent (§ 201 StGB).
In case of doubt, seek legal advice – the legal assessment always depends on the specific context of use.
No. The Mini Camera only works with Android phones that support USB-C and OTG (On-The-Go) — this applies to virtually all common models (Samsung, Pixel, Xiaomi, Huawei). iPhone models are not compatible because iOS does not support OTG. USB-C adapters or other workarounds also do not work. A list of compatible smartphones can be found under "Technical Details".
You can pay by instant bank transfer or by regular bank transfer, and from Austria also via eps. You will see all available options directly at checkout.
If you are in a hurry, choose the instant bank transfer: you simply pick your bank and confirm, the IBAN and payment reference are already filled in. The money usually reaches us within a few minutes and your order goes straight into shipping. With a regular bank transfer you type everything in yourself, which takes 1 to 2 business days depending on your bank, and longer over a weekend.
Credit card payment is not possible. That comes down to the card providers' policies, not to our shop.
If none of the options work for you, or you need your order urgently, just send us a short message and we will find a solution.
Our disguised mini camera sits inside a real shirt button and is hard to tell apart from an ordinary row of buttons. There is no visible lens, no blinking LEDs and no housing that looks like a piece of tech. With 2K resolution (2560 × 1440) and 4 megapixels, the button camera records sharply enough that even fine handwriting and facial expressions stay clearly readable. That is exactly what a disguised mini camera is for: recording without anyone noticing the camera at all.
The mini camera streams its picture live to your phone. You plug it into your Android device via USB-C, open the app and see the 2K signal on screen in real time. The sound runs in parallel through your phone's microphone and ends up in the same video file, in sync. You need no Wi-Fi, no pairing and no external power supply. If you want a helper in the next room to listen in and prompt you, combine the camera with our invisible earpiece and get the answer discreetly in your ear.
The hidden mini camera is used most often in exams and tests, from oral examinations and the Abitur (German school-leaving exams) through to state examinations or IHK trade exams. The button sits on your shirt, a helper outside the room watches the live picture and reads out the answer. For the complete setup, the cheating kit of camera and earpiece is worth it, and wherever a calculator is allowed, the Spickprofi Calculator with its notes function rounds things off.
How you wear the shirt-button camera depends purely on what suits your situation. You can sew the button firmly onto a shirt or blouse, attach it with the supplied clip to a collar, belt or lapel, or film out of a bag through a buttonhole. It also sits inconspicuously on a rucksack strap and blends in among real buttons. That way you will find a way of wearing it in any situation where the camera is not recognisable as a device.
Unlike classic mini cameras with Wi-Fi, the shirt-button version works entirely without a network and without the cloud. Because it sends no radio signal, it cannot be traced by a Wi-Fi or Bluetooth scan either. Compared with standard spy cams at 720p, its 2K delivers around four times as much picture information, and instead of a housing several centimetres across you are only wearing a button. The cheat sheet guide shows you further covert methods for exams.
At Spickprofi the shirt-button camera arrives ready to use: plug and play in under a minute, with step-by-step instructions and a list of compatible Android devices. That way the hidden recording works from the very first moment, with no tinkering.
