@mveloso The amount of electricity needed to run a dashcam for an extended period of time precludes that from being provided within the cam itself- the battery technology of today would make for a too-large cam. The main function of a cam's battery (and of supercaps too) is to allow it to properly close the last file without it being corrupted. I have a similar problem with my 70mai Dash Cam Pro Recently the SD card started to play up and not record. It then came up on the screen with the message; The SD card cannot be recognised. Please re-insert or change the SD card. At the bottom right it only allows the format button to work. The 70mai Omni dash cam costs $199 / £158/ AU$399 for the 128GB, $184.99 / £147 / AU$349 for the 64GB model, and $169.99 / £135 for 32GB of storage.

Step 1: Gently peel off the sticker at the back of the dash cam, and this will reveal 2 Philips Head screws. Remove the 2 screws and set aside. Step 2: Gently pry off the cover along the line highlighted in green. Only minimal force is required and be very gently to ensure you don't break the plastic cover. View Gallery. 11 Photos. The 70mai Dash Cam Omni's tripod head holds a 2G4P+IR lens that can shoot video at 30 or 60 frames-per-second, with an F1.5 aperture setting. The camera's two-phase Installation and setup is quite easy, both via the app and through the buttons on the camera itself. No prior dash cam experience needed. Video Quality. At day, the Vantrue E2 records very good video with both the front and the rear cameras. This means that you will be able to easily read license plates of other cars, even when just driving by. Dash Cam. Viofo A129 Pro Duo, A129 Plus (eMMC), T130, 70mai A800s. Apr 16, 2021. #8. Finally GPS accuracy and distorted audio recording issues have been fixed with this firmware (0.0.49.ww) It is so nice to see that some improvement is been done in the right direction. Hopefully we see more soon. 총평. 장점. 1. 70mai pro / 70mai 성능 차이는 크게 없지만, 70mai가 색감이 안좋게 좀 더 진함. 둘다 가격대 성능은 매우 우수하고, 번호판 식별도 매우 잘됨. 2. 국산 프리미엄 블랙박스와 단순히 화질 번호판 식별만 보았을때 비슷하거나 그 이상의 성능을 보여줌. 3. 128 QmwX.
