Another month, another dashcam in for review. Thank you to 70mai for giving me the opportunity to test-drive their latest rearview mirror dashcam solution, the S500. At this stage I'm sure the specifications of this device have been stated to death, but some other points worth noting are that this device does not have GPS and HDR is unable to be turned on or off. 70mai has included their own proprietary NightOwl Vision and MaiColor Vivid+ Solution image processing, so it will be interesting to see how this stacks up in the video samples in my full review.

Turning to the box, this is the best unboxing experience I've had yet. I'm a sucker for clean black svelte boxes, and here 70mai delivers in spades. Within the box are the usual suspects of the mirror dashcam itself, plastic pry tool, cleaning cloth (always nice to have) and the rear camera module with wiring. As of the time of writing, there is no official CPL filter available (yet) for the S500, hence its omission in the retail packaging. I also received a 70mai-branded 128GB microSD memory card, and their Midrive UP02 hardwire kit.

First impressions of the 9.35 inch fully-laminated display on the S500 itself are quite positive. I thought I would be left wanting due to its resolution of 1280x320 (equivalent to 141PPI), but honestly the legibility and colour profile of the display is quite pleasant. The dashcam in hand feels quite sturdy, along with the extendable body (and rotatable lens) which I required due to the larger rearview mirror in my vehicle (2020 Kia Cerato). Everything is placed where it needs to be, and overall thoughts on the build quality of this device are quite positive.

Installation of the S500 was a relatively straightforward affair. As I said earlier, I required the extensibility of the camera as I have a rather large rearview mirror on my vehicle, and the clips and rubber strapping on the dashcam were resilient. I did not have problems with vibration on my rearview mirror, and did not feel the mirror weighed overly much more than what a standard mirror would. Wiring the rearview module RC13 was a painless process too, and I wasn't offered a firmware update as it already had v1.1.23ww.2024.01.17 installed. Looking forward to see what this dashcam performs, which I'll dive deeper into in my full review, coming soon.




Some close-up photos of the 70mai S500 dashcam:

So I ran some benchmarks with the 70mai branded 128GB microSD memory card they sent over. Speeds aren't the fastest, but they're still pretty decent, so I don't feel like you'll be lacking with this memory card in your 70mai device.

A couple of photos below showing power consumption for the 70mai S500, running it through the included cigarette light adapter. On average, appears to fluctuate around the
~5W mark (dual-channel mode, 2.5K front & 1080p rear resolution). Temps look good too.


Also performed some temperature testing with the S500 running with its display continuously on for one hour. Decent levels of cooling and heat dissipation as to be expected for a mirror dashcam solution:

  • Outside air temperature: 28 degrees Celsius
  • Left-side of display screen (near front-camera): 41.6 degrees Celsius
  • Middle of display screen: 50.8 degrees Celsius
  • Right-side of display screen: 54.2 degrees Celsius

Screenshots below of the 70mai app for the S500 dashcam. One of the things I like in this app is the Timeline section, where you can hold and drag to scrub through the timeline to find the videos that you like. And it's categorised by the type of recorded footage.
