S1 versus the T2 - similar but differentReviewed in the United States on July 24, 2020
Both dash cams have excellent resolution. Both have a parking mode that I use. The S1 parking mode is only on/off, the T2 you can adjust the sensitivity to near/mid/far.Things I don't like about the T2:- it is big with the GPS mount. You can see it mounted on the right side of the mirror in the picture.- the buttons are on the bottom of the unit where you can't see them.- the screen is small.- it takes 2 hands to disconnect the camera from the mount if you want to take it inside.- the instruction manual is a poor translation. There are typos and camera features are not explained.- although its supposed to overwrite after filling the sd card, it will frequently not do that and just stop recording new video. The manual says to format the card every 1-2 weeks which is a pain, but that is what I have to do to keep it recording. A new sd card may solve that problem, but I haven't tried one yet. You also need to use sd cards rated for dash cams in order to get any longevity out of them (usually called high endurance cards).What I like about the new S1 are:- two cameras, although I haven't used the rear camera yet, just the front facing.- it mounts up higher out of the way and is easy to remove from the mount. You just slide the camera up about 1/2" and it comes off the mount.- GPS is built in, unlike the T2 where its part of the suction mount.- both the S1 and the T2 use capacitors instead of batteries and are supposedly more heat resistant. I did get a sd card fault with the S1 which I attributed to high heat, but it has only happened once so it could be something else. I'm using a Vantrue 256 gb sd card and have not filled it up yet.- the buttons are on the front of the camera where you can actually see them while driving. Very important to me.- the S1 has the option for 1080-60fps when only the front camera is used. 60 frames per second vs 30 frames per second means more detail.Things I don't like about the S1:- the manual is still poorly written with typos and incomplete descriptions. For example, it tells you how to turn HDR on and off, but doesn't tell you what HDR is. Same with EV exposure correction (what is it for?). Same with setting the Hertz (when do you use 50hz vs 60hz?).- the physical buttons are labeled "<" and ">" but are used to move the cursor up and down.- the screen is hard to see because of the angle. It would be nice if the screen tilted. What I end up doing is slipping the camera out of the mount when I want to change settings. Granted, I’m in my 50’s with bifocals, so you may not have trouble with that. Depends on your windshield angle, too.Overall, I prefer the S1 to the T2 because of the size, mounting and features. Both are high quality cameras and get good reviews in other publications. I like having capacitors instead of batteries. I like having the parking mode. I like having the ability to use high capacity sd cards (most dash cams cannot use 256 gb cards). And so far they have held up well (the T2 for over 2 years and from Washington to Arizona).EDIT: the actual video I uploaded to this review is much better than what is shown online as far as clarity and resolution. Amazon, like other sites, probably compresses the file which drastically lowers the quality.
