A unique feature for this dash cam is voice control (only available in English and Chinese). The camera has 4 voice commands available:

If none of those are deal-breakers, though, the 70mai Omni offers excellent value for the price. Most notably, you'll get a high level of picture detail, and let's face it, that's the main thing most people will be looking for. It's also great to be able to control this dashcam by voice, and anyone creating social media content from their car will love fun features like the ability to take a selfie. Note that there are no hardware differences between the International (English), Chinese and Russian versions of this camera. Any language firmware can be flashed to the camera. The other thing that might slightly confuse people is that you connect your phone to the 70mai Omni via its own WiFi. Because I was parked outside my house, my phone initially refused to do so, because I'd set it up to auto-connect to my home WiFi, which was still in range.

Some owners have created custom Firmware for the Dash Cam Pro to improve video quality. You can learn more about the custom firmware here. User Manual

WARNING! MAKING CHANGES TO YOUR FIRMWARE ARE PERFORMED AT YOUR OWN RISK. WE ARE NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR DASH CAM AS A RESULT OF THESE INSTRUCTIONS. Firmware Update Instructions Hold down therightmost buttonand turn on the camera by pressing the large long button in the middle of the camera. Hold the right button until the update message appears, and then release it. The camera does not come with GPS or any form of parking mode. It also uses a battery rather than a super capacitor making it not ideal for very high temperature environments. The lens itself provides a 140-degree field of view, but the camera can rotate within 340 degrees on request, either via the app or voice control. In other words, you can say things 'shoot left', 'shoot right', 'shoot inside' and it will automatically spin around and do so. This has worked perfectly every time I tried it... well, as long as I say it quite loudly. Perhaps this device is calibrated to the stereotypically louder voices of North Americans, and my quiet British reserve has it stumped. The 70mai has a nice cylindrical design and is small at 100 x 55 x 32 mm. It does not come with a screen and can be mounted discreetly in your vehicle. The form factor is very simple with one power button providing multiple functions (power on, power off, turn on WiFi, turn off Wifi, format SD card and restore default settings).The camera uses an Mstar MSC8328P processor and Sony Exmor IMX323 CMOS sensor. This combination allows for 1080p at 30fps video recording using a bit rate of 16Mbps. Video quality is very good during the day and average at night. While video quality is not as good as some pricier cameras, particularly at night, for the price, video is impressive. OTA_9_FULL_DR002_v1.0.6.eu_20180817-1641_full.zip Chinese to English Firmware (Add English voice to Chinese cameras) I share this experience for two reasons. Firstly, I'd advise you pay more care than I did when attaching the dashcam initially. But as a broader point, if you were planning to remove the dashcam at the end of each journey (seeing it as a temptation for thieves) then this is not the choice for you. It's designed to stay up permanently.

Good value for such a low priced camera. Won't find better at this price but may be worth it to buy a B1W for a few dollars more. The 70mai Dash Cam Pro records 2592 x 1944p video at 30 fps using a bitrate of 19.2 Mbps. Note that this resolution uses a 4:3 aspect ratio which is unusual. We suggest using the 2560 x 1440p resolution which uses the more common 16:9 aspect ration. Both of these resolutions use the H.265 video codec. If you prefer using the more common H.264 video codec, you will need to choose a resolution of 1080p or lower.There are 2 methods to update the firmware: via the app (follow the instructions in the app) or manually (follow the instructions below). The 70mai Dash Cam Pro has a wedge shaped design and is small at 87.5 x 53 x 19 mm. The camera comes with 2″ Screen, WiFi (with Android and iOS apps), G-sensor and optional GPS.
