Thanks all, I'll try factory reset first and flash the latest firmware and see if it works.
For beep alert, it's not the settings, alert is enabled. Whenever I access the app and stop the recording, the beep alert is working. So I really unsure why the few occasions no warning for the failure to record the footage.

Bro, gentle reminder, pls ensure switched off the wifi all the time. Only switched it on when want to view recorded video clip.

I always do that, in fact in switch on and off everyday (not sure if that will somehow affect the device becoming unstable, but it shoudn't).

Because when I reach home, I will disable the parking mode, then when I reach office, I will enable it again. So quite troublesome, I have to switch on and off everyday

So bro, do you mean you are using wifi connection to turn ON and OFF for the parking mode everyday using the phone apps?

Do you mind to stop using apps to change the setting if what i assume as above is correct. Just for monitoring till you send back to your seller.

Pmed me bros, if you are in klang valley. I can come look for you and check the unit. I have demo unit for you to try.

why do you need to turn on and off the parking mode ? cant it just be left turned ON only ?

Yes I'm using phone to on and off the parking mode
Thanks for your offer, let me try to reset to factory settings first and see how it goes.

I'm not sure how bad the parking mode will affect my car battery, that's why I turn it off when parked at home, because my house is gated so I don't need the parking mode on.

For owners using the A129 Duo's parking mode, turn off the wifi when not in use and not leave it on always. It will burn the wifi module very fast.

Thanks for the info, if burn already can it be repaired/replaced?
Without wifi it's rather useless

Need to send for warranty claim.

Just imagine those who bought cheap without warranty

But warranty only 1 year right? After 1 year koyak liao very troublesome

I mentiond before that I keep turning on and off wifi (to enable and disable parking mode) as I posted earlier due to wanting to "save" the car battery when park at home (gated). Now with this risk of damaging the wifi, I really wonder, shall I just keep the parking mode running round the clock, and will it really shorten my car battery a lot

Their WiFi module isn't the good type to begin with. File transfer with 2.4ghz and 5ghz no speed difference. I may as well stick to 2.4ghz. Peak at 72mbps transfer speed, and that's a very poor bandwidth.

If you're using the Viofo parking 3 wire kit, it should cut off upon detecting the low voltage of your battery. Well, that's the safety cut off to begin with.

The new Viofo A129 is going to be called A129 Pro 4K with 4K front cam resolution and 1080p rear cam resolution.

Sicurez told me to set the cut off at 12.4V just to be safe.

Also, I prefer to take out the micro SD card and use an OTG card reader that I store in my car to watch on my phone. Wifi too slow and sometimes the stream quality is not that clear.

Agree on the 12.4v as well. The higher the better, lower risk of draining the car battery to lower Voltage.

The WiFi module for A129 has room for improvement on hardware level. I guess that's the downside of the WiFi stability of A129.

Yes their wifi transfer rate super sucks, and damn so regret now with 4k should have waited for this new one if I knew it's coming

Still in the testing phase now. Not yet announce but should be this year also I guess.

hopefully can really record a fast (>80km/h) moving car number plate on day & night CLEARLY this time

I don't think any camera can record a fast moving object clearly day and night leh

Hi! I read some reviews suggested that the WDR should be turned OFF. May i know why? I thought this function is good to be turned ON?

May i know what are the recommended settings for G-Sensor and Boot Delay?

For WDR, some people like it and some people don't. So you'll need to see which you prefer.

Boot delay I put 0. G-sensor I put mid sensitivity.
