I have had my 0806 with two 64Gb Samsung Evo cards since February 2015 in the front of my car which replaced the 2014 0803 with a 64Gb Samsung Evo card which is now in the rear window.

After being on the forum for some time now I have noted that the majority of postings appear to be problems or complaints about the 0806 but my 0806 has worked perfectly since new with the exception of the card switching problem.

I appreciate that it will be people with problems or faults that will be the main users of forums and we will therefore never truly know the extent of the number of working cameras and this may well be a factor in putting people off purchasing this camera and the same will probably apply to any other model of camera.

The car is used daily and usage varies at between 45 minutes and 6 hours each day and the GPS locks quickly every time, focus is spot on, the battery is still going strong, the micro SD cards are still working as they should and have only ever been formatted once as Fat32 at first use, no power connection problems and in fact I can't think of any failure of any sort at all and the camera only comes out when I need to access the card to copy any files off otherwise it stays in the windscreen.

For that matter the 0803 has always worked as it should and still does.

Both cameras are powered from a dual USB cigarette lighter supply when the ignition is on and when the ignition is turned off they automatically switch to a power bank for power which is capable of running both cameras for about 20 hours if necessary but can be switched off individually or left running until the (variable) timer turns them off. When the ignition is switched on again the cameras are again powered from the car supply and the power bank is also charged up again.

I suppose now that I have put this in writing it may be the kiss of death but hey-ho maybe I have been lucky.

Hello shunter293
Would you mind sharing a schematic of how you wired up the switching from ignition on to ignition off power for the cameras
I have been playing with the idea myself and am curious to see what really works.
Advice on 5V battery make & model appreciated as well as info on the timer
How's that for a long-winded way of asking " may I pick your brain?"?
Regards

Good luck with your dash cams. The fact that many complain about them signifies the model has issues both in manufacturing and in use. I've had two and both displayed the same faults. 0805 was and still is working OK. It is a simpler cam, so maybe that;s why.
 
from our warranty and repair record, here are the trouble shot:
1st, PWM IC damaged - the IC can only handle 6V input voltage, but many power device have much higher insant voltage. Ambarella chip is also very sensitive on power supply. rate 65%
2nd, battery dead - the lithium battery was designed to work under 50C(120F) so we marked the working temprature up to 40C (human adaptability under 40C). But obviously the working condition is not in control. 25%
3rd, crash - cause by card problem or other (need to reboot ARM, long press only reset DSP); bricked; rate 4%
4th, GPS lose - POGO pin problem + goden plate buffing + cable problem + miroUSB connector fault; rate 3%
5th, others

for now, we have to design a voltage cut off circuit in 0903plus to avoid 6V+ power through. That is not an ideal plan for me.

if anyone can recommend a PWM chip which support 3V to 30V(3V-9V at least) input voltage and adjustable output voltage / 1A current, that will be helpful.
 
My 0806 worked very reliably for a long time until I recently 'upgraded' from 32GB cards to 64GB ones.
These now cause occasional problems with the intensely annoying alarm going off and difficulty shutting down to silence it.
So the moral is, if it ain't broke, don't fix it (even for an 'upgrade' - you may end up DEgrading it.)

FWIW the problem happens most within a few minutes of powering up. And despite the problem being a file write failure, it usually works fine if I power off and back on, without reformatting the card. Reformatting does not offer any advantage in this particular case.

Better card is on order. Fingers crossed.
 
If what you say is true, why are 0805 dash cams more resilient to breakdowns? Also, if you KNOW the 0806 has issues - why put it on the market and let people suffer? Get your model's issues ironed out and then you'll have better product and satisfied customers. Makes sense? Unreliable products harm manufacturers much more than anything else!

I would rather have an 0806 than an 0805, my 0806 is just coming up to 1.5 years in use and is still working fine, currently with a Samsung EVO 64GB.
 
GB has 806 on April sale for $86. If didn't buy 903 already, I would be all over the 806 at $86.
 
My 806 has worked fine for over a year now other than the focus issue which it has had from the factory. There are some production problems, but dealing with budget imported dashcams you just have to plan for that. While mine does not perform as well as it could if the lens was aligned properly, it still has performed well after using it every day for over a year. For the price paid, I call that okay.

One thing that I've learned with these is to never buy from a place that won't let you return the unit without a hassle.

EDIT: Due to every Mini cam Ive purchased having an issue, I certainly won't be buying another one in the future.

I have the 0826 , and previously the 0805 ...
0826 has soft focus , the 0805 had GPS issues ..
ATM I would not be all over a Mini , no matter the price ..
I think the price on the Ausdom A261 is also down @ GB ATM ...
 
Ausdom price is so tempting, if it wasn't for the light yellowish pictures samples.
