As I recall, Viofo removed 5GHz in later firmware.
I don't see any dropped video frames in the A229 Duo rear camera video around that timestamp. My best guess is that there was an A229 realtime clock adjustment to sync it with the GPS time.Also, while reviewing the footage from the A229 I noticed the time on the text overlay skips 11:18:56.
It goes from 11:18:55 to 11:18:57.
What happened to the 56th second?
Is this what is referred to as a dropped frame?
45 degrees is the angle that CPLs work best, so your A119 Mini is working brilliantly! On a 30 degree car the A119 Mini CPL would only be 2/3rds working, and lots of modern cars are nearly vertical, which results in the CPLs only 1/3rd working or worse, which is why we tend not to recommend rear CPLs, they are often disappointing.Maybe my car has something to do with it?
My rear window is very upright at around 45 degrees.
I have a feeling most modern cars have a much sleeker rake at around 30 degrees.
The clock on the rear camera is being updated about every 1.03 seconds instead of exactly every second, the clock update is out of synchronisation with the frame rate. After a while it has missed a complete second, so we see it skip one second. If you watched for long enough and counted how long it takes between each skipping then then I think you would find it to be a regular occurance, and you could correct my 1.03 figure which is probably a little out because I didn't collect enough data to get it accurate.What happened to the 56th second?
I want my MTV! lolIt would be nice to have the option though!
Right on Lothar,Noticed that you tested A119 Mini at "High Bitrate" vs "Maximum Bitrate" on the A229, so this is not an apple to apple comparison.
Any particular reason why? or is it that the A119 Mini couldn't stand the heat at "Maximum Bitrate" so you lowered it in the settings?
lolI am polishing my big black helmet.![]()
So are the settings named incorrectly on the A119 Mini, it should be Maximum, High and Low, so that the bitrates match those with the same names on the A229?The A119 Mini has three Bitrate settings;
High: 30
Medium: 25
Low: 18
The A229 Duo has four Bitrate settings;
Maximum: Front 29 / Rear 25
High: Front 24 / Rear 19
Normal: Front 20 / Rear 16
Low: Front 17 / Rear 12
(all bitrates in Mbps)
Perhaps the temperature of the Mini case is higher than that of the A229 due to the better heat dissipation from the processor in the Mini ...More useless “gentle” heat testing.
The next 5 days are forecast to be 100℉ - 105℉ (37℃ - 40℃).
I thought I would take advantage, and do more “gentle” heat testing on my Viofo A119 Mini, Viofo A229 Duo, and Vantrue Element E1 that are installed in my car.
My car is parked in the garage out of direct sunlight, but ambient temperature of my garage is almost identical to outside weather conditions. It does not simulate real world parking mode scenarios performed in direct sunlight, but it does offer insight how well the cameras dissipate heat, and how they compare to each other under identical test conditions.
I start the cameras at 6AM in normal recording mode, and let them run until 8PM non stop. I monitor them throughout the day checking for signs of overheating like shutting down, or recording stoppages, or any other malfunctions.
5PM - 6PM is when the cameras really start to cook, and the highest camera temps can be measured. I obtained the following temp measurements at 5:30PM.
Outside Temperature: 99℉ (37℃)
Ambient Garage Temp: 96℉ (36℃)
Garage Relative Humidity: 35%
A119 Mini: 145℉ (63℃)
A229 Front: 140℉ (60℃)
A229 Rear: 111℉ (44℃)
Element E1: 138℉ (59℃)

Is that with both running a single channel?under equal conditions the temperature of the A119 Mini processor is lower than the temperature of the A229 Duo processor.
A229 Duo = This is a dual channel model.Is that with both running a single channel?
Or maybe they should stick to the same 4 settings standard that they use for their other cameras (low, normal, high, and maximum)...I remember the A139 having 4 setting toggles when I studied it way back when.So are the settings named incorrectly on the A119 Mini, it should be Maximum, High and Low, so that the bitrates match those with the same names on the A229?
Or maybe the A229 settings should be High, Enhanced, Normal, Low...
A119 V3 has 3 bitrate settings, same as A119 Mini.I don't recall if the A119 V3 that this A119 Mini replaces has 4 bitrate settings or only 3.
Perhaps the temperature of the Mini case is higher than that of the A229 due to the better heat dissipation from the processor in the Mini ...
Thanks to the work of user Dex_ , I am able to see the temperature of the processor in the Mini and A229.
I also carried out a temperature test of processors on the Mini and A229 Duo and under equal conditions the temperature of the A119 Mini processor is lower than the temperature of the A229 Duo processor.
Good to know. I can understand why they stuck to these same exact settings for the A119 Mini then.A119 V3 has 3 bitrate settings, same as A119 Mini.
