Question: Please- what settings work best  a short drive now gives me multiple files  instead of one.
Document: First time I used it I thought it was a great deal. If it worked it would be a very nice appliance, but..It would only work in the morning when it was cold and/or low brightness. It would never work more than 3 minutes in the afternoon when it was bright and/or hot. I tried multiple settings. It suffered multiple crashes of different sorts, just stopped, screen had lines, screen went blue.
This dash-cam locks up every hour and needs to be reset by shutting it down. I have to monitor constantly to ensure it is even running.Menu - the buttons or the software broke, now it skips every other item in the settings menu.Recording - doesn't usually record in 3 min chunks, but when it does, it goes to the next file in 1-2 seconds, creating 2 files in 3 minutes. Usually it just goes to the next file randomly in 15-90 secs.
I purchased this camera about 10 days ago. It is really tiny and unobtrusive. First the set up instructions are useless. Just keep poking around until you figure everything out. The camera works fine when it works. I have found that when you try to us the computer to check what is recorded Windows media player crashes constantly. For every 5 files 3 were corrupt. It records for short time and stops then starts recording showing 2 files for the same time stamp.
Alright, my last review was before I had tested it with multiple memory cards, but the situation is no better. With whatever card I use, I will start the recorder. Everything seems to be working fine for a few minutes. After 2 to 10 minutes, I will look at the display, and it will be frozen.
Froze a couple of times, but other then that it's a good camera for the price. I probable would buy it another one
I purchased the 32 gig micro card that was recommended The instructions said to reformat the card if there was any problem. That didn't work. To remove the micro card you have to use a tweezer, fingers are not an option unless you have long finger nails. I wish there was some way to make this reliable it is a great size.
This camera is great , It is economical , small , easy to use, and has great picture quality. Couldn't be happier. Recommended one to a friend and he got it and loves it as well. Evidence is  Indisputable when it comes to an accident because you will have it all on tape. Man up and get one. You will be glad you did like me.
After reading further reviews of similar priced camera's I came to the conclusion you get what you pay for. I have now bought Smarty BX1000. So far so good. Another note, the manual is definitely lacking. It tells you trouble shooting points but not how to actually change the settings. Example. It says to change the light setting but no explanation of which way to go for what purpose. I had to go online and figure that out myself.
Oncoming cars headlights do not bother the dashcam. The dashcam is also equipped with infrared lighting that only the camera can detect but i have had no luck while using it at night in the car. It does work well in a dark house if you don't have a flashlight nearby. Overall the quality of the camera is what I expected, the camera is equipped with more feature than I expected, and the camera works great for what I need it for. For the price you cant find a better camera any cheaper.
Don't get your hopes up; Street lights and headlights light up the area a lot better than night vision does.MOUNTING - The listing shows a different (cheap plastic?) mount that apparently uses double sided tape to attach but that is NOT the mount this camera comes with. A nice suction mount is included and it holds very well. It is very small at 2.25" wide X 2.25" tall, so for most folks it will work just fine.
Answer: I think in setting you can make the file length in 1 minute increments, with 3 minute maximum length. Now, it's not going to be 3 minutes exactly, but pretty close. I had multiple files creation before I got a Class 10 card, I think the card wasn't keeping up with the data.
