I have been able to reproduce the stopping this afternoon. At 2ch max bitrate the recordings keep stopping at exactly 48seconds. Every time again and again at 48sec. At high bitrates it also stops sometimes after a couple of loop recordings.
Looks like VIOFO has maxed out theax bitrate setting too high.
In conclusion: i will NOT buy or try another card. Simply stupid design of the A229 DUO. IMHO Viofo has to come with a solution. Everybody is trying to fi d a suitable card. Better look for another cam.
Hello Kenza,
I would like to offer my worthless opinion before you throw your A229 down a flight of stairs in a fit of frustration. I’ve been testing / using an A229 Duo since July 23, 2022. I do not believe your issue is caused by the SD Card, Bitrate Setting, or the A229 Dash Cam itself.
Based on my power consumption testing the A229 is “power hungry” compared to other dash cams I’ve tested. During testing I discovered two “power starvation” malfunctions by accident. When I first receive a dash cam I run it off a power bank on my work bench to verify everything works before I install it in my car. I have two different power banks. One has a rated output of 5 Volts 1 Amp, and the other has a rated output of 5 Volts 2.4 Amps. By luck the 1 Amp power bank was on my work bench, and I discovered half the time the A229 would boot up, and start recording as normal, other times the red power LED would illuminate, and the camera would shut off, and begin an endless start up / shut off loop. I tried using the A229 with my 2.4A power bank and start up & operation was 100% reliable. This must be why the supplied Viofo cigarette power adapter also has an output rating of 5 Volts 2.4 Amps.
After I got that sorted, I installed the A229 in my car. Since I just completed testing the A119 Mini, I decided to remove the A119 Mini, and install the A229 at the same location on the windshield. Since I already had the USB Type-C cable from the A119 Mini installed, and routed behind my headliner, and panel trim I decided to use the same cable. Guess what? When I connected the A229 to power using the USB Type-C from the A119 Mini it started the same endless power up / power down loop. After closer inspection the USB Type-C cable included with the A229 is 20AWG. The A119 is only 22AWG. The thinner gauge wire used by the A119 Mini was causing power starvation endless loop.
So why am I telling you this?
I’m assuming you are using the Viofo HK4 Hardwire Kit to power your A229.
Here’s the part where I start jumping to conclusions. I willing to bet dollars to donuts your car is newer than 2005, and you have the Battey + (constant hot red wire) of the hardwire kit connected to a fuse that is on a circuit that has a power fluctuation while the car parked, and the A229 is operating in parking mode. Usually cars made after 2005 have a more sophisticated OBD2 system with up to 200 different modules that take anywhere from 30 minutes to 1 hour to “fall asleep”. And some modules stay permanently active. OBD2 systems in cars from 1996 - 2005 were much simpler, and only had one or two modules.
So how can we diagnose if this “module power fluctuation” is the cause of your A229 recording malfunction?
Well, if it were my car I would connect my multimeter (Amps) in the circuit that is powering the hardwire kit, (red wire) and shut the car off to enable A229 parking mode, and then monitor my multimeter for one hour looking for power fluctuations that correlate to a recording malfunction of the A229. But I doubt you have an hour to waste like that. So it might be a good idea to remove the red wire from the fuse box, and temporarily connect it directly to the positive terminal of the battery, (with an inline 5 Amp fuse of course) and monitor for malfunctions just as you have been. If there are no more malfunctions, that was the cause, and you need to re-connect the red wire to a “constant hot” fuse that does not have power fluctuations. If the malfunctions continue everything I just wrote was a waste of time. Lol
