The car i just bought had a 70mai m800 4k harness already installed and hard wired in, so i figured i'd try it, the camera works well, the video is very clear and the app is quite responsive, but it does say it has parking mode and it doesn't really, you need to buy an extra little module thing to go along with it. Good value for a $250 camera though.

70mai is easily the best value. Different levels of video quality to choose from for different price ranges. I bought 3 of the A810 cameras, one for each of my vehicles. Super clear both in day time and night time, and they come with rear cameras too. The person warning you about wires likely has never installed a dash cam. I installed all of my cameras using one of the circle power outlets in the vehicles. Sure, I don't have continuous 24 hr surveillance but I don't really care for it. The hardest part was just tucking the wires behind the trim as nearly as possible, but even that is pretty easy. Highly recommend the brand for it's value (with the exception of their X800 or any of the overpriced egg-shaped cameras).

You'll need STRAVIS 2 + 4k sensor to read number plates in night. (Viofo, 70 Mai, qubo etc). True 4K preferred. 70 Mai is a good option which is value for money. You'll get 4K at around 20k. A polorising lense cover recommended, which will cost another 2k. If budget no barrier then go for viofo, which is better quality with added advantage of super capacitor instead of standard lithium ion battery. So temperature variation won't be a concern. Youll have to shell 35k+ for front and rear camera. Check seller name AATUSA, who is the official distributor. Else contact them directly, they will provide you the Amazon link to order. If you need direct contact please DM. I've gone for viofo.

Not really. If you want parking surveilance you have to wire from obd wires anyway (I know that camera manufactuers suggests wrapping fuses but it's fire hazard) which gives ability to connect to camera from anywhere.

Dont worry its not that hard to get fy 7omai with 4g hardwire kit from obd, it will give you ability to connect to camera anytime, as this usb port even if you have is not always hot (if I remember correctly). I did mine on 2021 atlas and it took 5-10min if even to route cable under pillar trims and that soft roof thing not much more of wire visible

I went for 70mai because 4g wire kit for parking surveilance - if you don't have garage, and/or leave car when shopping you get notification if anyone hits your car together with video, or if someone is areound your car for too long.

I have a 70MAI in both our cars, the one without a screen. It works flawlessly. I have only downloaded videos twice, and the quality is good. Not HD, but good. Had it for more than a year and can not complain.

I'd say before buying dashcam check it's review in youtube and only get dashcam which has 4k quality and night vision imo 70mai is good it has starvis imx and 4k res

I did some research back in 2023 and ended up with a starvis 2 model from 70mai (one of only 2 that were available at the time, the other was a viofo). I’m very happy with it!

70mai from Xiaomi are amazing cameras and in the same price range . Not sure if available in your country but they should be available for orders or on Amazon. Just pay attention what version you pick up , get the one with 4k sensors.
