M3 Motorcycle Helmet Dash Cam & Intercom, High Video Resolution 1080P 30FPS, Camera Recorder Headset, Bluetooth & WiFi, IP65 Waterproof, Sandisk 32G Memory Card, Since 1991, Taiwan Design

Pros: Inexpensive, excellent battery life, fairly small, includes good set of accessories.Cons: Sound quality is middling, app is... very much a product of someone who speaks English as a third or fourth language, image quality is middle of the road - not bad, not great. USB charging cable included with device is very particular - many USB cables will not clear shoulder of case to fully insert in the charging socket on the device. If you lose the included cable, you may have to try several before you'll find one that will fit.Not Tested: Intercom capabilities.This is basically the same device as the Maxto M3. Whether it's truly designed in Taiwan as advertised or a typical mainland Chinese knockoff I don't know; I'm not aware if the Maxto or Arzin came first. Designer is listed as Aiwill Tech Co in Taiwan, manufacturer is Moya Communication Tech in Shenzhen. Build quality is pretty good, though I'm not sure it retains its IP65 protection when you have the mic/headphones/USB charge cable attached. Those ports are covered with small, tightly-fitted rubber covers - they are tight enough it takes a very small, sharp object to pry them open - but when you have the accessories connected these must be pulled aside to plug in the connection. Three buttons on its edge toggle the various main functions - Bluetooth, WiFi to connect the device to your phone via an app to change settings or view footage, and the DVR. A fourth rocker wheel with a large, easy to hit round face controls things like volume, pause/play, call answering, next/previous track, etc. Controls are generally pretty well thought out and give quick access to the things you'd want to get to in a hurry (double-tap wifi button to manually save a recording, etc). Comes in an attractive box that doesn't look cheap. It also has an FM radio function not really described here; it's basic but you can scan through local signals if you want to.The app (I only had access to the Android version) is extremely bare bones and primitive, with lots of Chinese-English neologisms and errors. You can generally get what you want done by trial and error, such as change recording settings, view the videos on the SD card (which is an included 32gb SanDisk Extreme, rather than a cheaper brand), adjust the sensitivity of the shock sensor, etc. One problem I had with it is that it 'locks' a video when a shock is registered or you toggle the WiFi button twice; this keeps the rolling loop of 5m videos it's always recording when the DVR is turned on from overwriting those files. I couldn't find any way to delete these files manually after downloading them to another spot, though, the only solution is to reformat the SD card as far as I know. This isn't a huge issue, you'll probably want to dump those files somewhere safe after an accident or event and start fresh, or maybe keep the SD card as it was for an accident investigation and pop in a new one. You can view videos on the fly on your phone, which could be useful at an accident site.The sound quality is not great, but certainly acceptable for GPS directions or music, depending on the legality in your area. Included are two velcro-backed headphones (not L/R marked if you're a stickler for that sort of thing, but I suppose you could experiment to determine this) and two interchangeable mics, a flexible boom for a modular or open-face helmet and a shorter but smaller velcro-backed mic pad you could stick to the inside of a full-face helmet.I had no trouble affixing the clamp bracket to one helmet and the stick-on bracket to another. I prefer the clamp bracket since it's less likely to experience adhesive failure suddenly after time. If you switch back and forth between two helmets like I do, you can easily find spare clamps or mic/headphone setups for a handful of bucks on AliExpress searching for the Maxto M3.The battery life on this is really the high point - I commute daily to work and can generally go the whole week with Bluetooth and DVR recording before charging it. Course, that may vary depending on your commute time, but I was impressed by the longevity of the Arzin's charge.Generally was pleased with this product as an inexpensive alternative to some higher-end competitors. Did not get to test the intercom functions as I don't have multiple Arzins or other folks with Bluetooth intercom sets to try to connect to (it says it will connect to a non-Arzin device). As a DVR and Bluetooth hands-free for calls, GPS directions, music, etc. it has served me well to date.

This helmet cam worked just fine until I was in an accident.One key thing to remember about the camera it is mounted on the outside of your helmet.The camera was ripped off the adhesive bracket and was wedged in the road when I hit the asphalt and rolled.The camera was destroyed and would not turn on after the accident.Prior the accident it worked fine.

First of all, unlike so many other reviews on Amazon, I am not getting free stuff and then telling everyone my reviews are honest. Every review I write is based on a product I bought and use and I get nothing in return except sharing information. I will not even consider any review where the reviewer got something free to review and neither should you.I have used more than a few helmet cameras from rather expensive models to the lower priced items. While the very expensive cameras work well they are often bulky like a small box, limited in features and are priced more for their name than how they work. The very inexpensive models usually don't work at all or are so complex because their firmware isn't well done that using them is a hit or miss. The very idea of a helmet camera is that it needs to be reliable, simple to use, have good features and just as important as the camera it needs a well written user manual since they don't often come with displays to use the menus.This helmet cam checks all the boxes. The very first thing I did was charge it as should anyone buying a battery operated anything. That just makes sure that there is enough power to run the device properly. The camera charged quickly; that could be because it had a good charge already or its just an efficient charging system, I won't know until I've used it for much longer rides. I'll update my review as time goes on.The first thing I noticed was that the manual is well written, accurate and easy to understand. If the manual was originally written in a language other than english then the translation is about perfect and that makes a difference. I highly recommend you read the manual first and note the location of each button so that you aren't just guessing. Reading the manual takes only a few minutes but is well worth the time, it eliminates frustration later on.The buttons and controls are really easy to use. Some other cameras are so clumsy with control you are never sure if you worked them or not. The controls on this camera are very easy to use by touch, an important thing when you are riding your Moto since everything has to be done by touch. The layout and placement of the controls are the best I've ever experienced. There is no guessing where the controls are and with good spacing between the video and photo controls you will not make a mistake and press the wrong one. Who hasn't gone on a ride only to find out they pressed the wrong button and took a picture instead of video recording and after the ride discovered there is no video? That won't happen with this camera, you'll know which button or control you used.The quality of the video and photos is excellent. Lets remember that this isn't some expensive 4K or now 8K camera, it's HD and its purpose is to record photos and video from a helmet mounted position for safety and general entertainment, capturing a record of your rides and taking picture of interesting points. It does that as well as any camera and better than most. The video is very clear and stable. I even took the camera off the helmet and walked about my property, running, shaking it, jumping and turning around faster than any riding would do and the quality is amazingly good. The same for the pictures.The audio recording likewise is very good and the speakers are more than sufficiently loud even when riding a bike without a fairing, I used it on two different bikes, one naked and the other with a really good frame mounted fairing. The camera's audio was very good on both.I paired the camera to a higher end smartphone and a basic phone and each paired very quickly. The visual indications for pairing are something you can't mix up, no tiny impossible to see lights, the visual cue makes sure you've done it right.The accessories that come with the camera are top quality and equal to any other camera and better than even some high end cameras. They are sturdy and only time will tell if they are durable but I'll update this review as time goes by.One really nice thing is that the charging cable is nice and long so you don't have to figure out how to keep the camera close to the charger. It's also long enough so that you can plug the camera into one of those external battery packs for charging or even connect it to a smartphone that has the newer two way USB power connections. So many cameras come with a short charger cable, not this one. Its also a sturdy cable so durability isn't going to be a problem.The helmet connector has both a clip on and an adhesive mount. The clip on is secured with strong screws for the clamping portion so it will remain secure and the adhesive version gives you that very flush fit. Note that if you use the clamp bracket make sure the edge of your helmet doesn't fold under or have a large radius bend as there might not be enough of a clamp to make it secure. That isn't a fault, it's common to all such mounts. In that case just use the adhesive version that's included.TIP: When mounting the adhesive bracket, first connect the camera to the bracket and then using painters masking tape or similar secure the camera and bracket to the helmet and record some video and photos. Do this while seated on the Moto so that you can get the angle just right for your riding style. The you can use an erasable marker to outline the position and proceed with the more permanent adhesive attachment method. Just make sure that the helmets surface is clean, really clean. I use 99% alcohol but just wipe and then dry off, don't leave the alcohol just sitting on the helmet finish. It's just a quick wipe, back and forth and then wipe off using a different cloth. Then, you want to make absolutely certain the position is correct and why I recommended temporarily positioning the camera first because the 3M tape is very strong and bonds instantly. If you make a mistake, use fishing line or even nylon thread to go between the helmet and bracket to get it off. That way you won't damage the helmet or the bracket.Recommendation to vendor: Consider including an extra tape in case someone makes a mistake, it can happen.The camera comes with a Sandisk memory card, that says something because most other cameras don't include a card or they send out some card from some unknown source. This is a top quality memory card and mine had no errors and using it in a laptop wth an adapter made going through videos and picture really easy and that is the method I prefer over any other, it works, it's easiest to manipulate the files and so on.I didn't try out the WiFi yet as I really don't have much use for it. Wifi is very power intensive, and this is a camera so it's battery although very good really isn't designed to be the primary source for powering wifi. So far, no camera I've ever tried with a wifi feature has worked as well as you want. it's just the limitation of the type of device and nothing new here. However, since the memory card is so accessible and easy to use, it makes sense to just use an adapter and do it that way. They make SD card adapter that can connect to smartphones so if you are out on the road and don't have a laptop handy the adapter will do the job just fine.In summary, would I buy another? Yes. Would I recommend it to family and friends? Sure. Am I happy with my purchase? Absolutely.At the price of this helmet camera there really is no excuse not to use a helmet camera, it can make a difference in safety and enjoyment for your rides. One other nice thing about helmet cams in general is that should you have to work on your bike while on the road, you can record what happened and how you fixed the problem. As Moto riders we all have interactions with others and sometimes car drivers and so on aren't always courteous or friendly. A video record is always a good thing to have and when someone notices you have a helmet camera, often just that can change how they react to you, get one and I recommend this helmet camera above all others unless you are making feature length movies or are trying to do some professional movie making.

The picture quality is second to none but as far as the wifi feature? Nonexistent. And the app? In the year and a half that I’ve had this camera I’ve been able to use the app a grand total of: 1 time.
