Hello,
I have a Viofo A139Pro 1-channel with HK3-C, FW=1.1_0615, App=3.2.12. I am using the camera in a Fiat Ducato-based motorhome, mainly to complement our travel videos.
I have two kinds of problems.
First, when powered from the HK3-C, the camera does not behave as expected. If I have the BAT and ACC leads conneted to their respective fuse taps, the camera remains powered indefinitely (does not shut off when the engine is shut off). If I disconnect either of the BAT of ACC leads, the camera will never turn on. My temporary solution is to connect both the BAT and ACC leads to a KEY-type fuse tap. Of course, this means that I cannot use the parking mode.
Second, it took me a really long time to understand why the camera sometimes (=seldom) works as expected and more often does not. Even if the camera says "Recording ... Wifi enabled", it does not necessarily mean that the camera records or has Wifi enabled. I finally understood that it is mandatory for the camera to also announce "Wifi connected". If this happens, I can connected my phone with the camera and verify that it is indeed recording. In order to arrive at a working condition (=recording with Wifi connectivity), it is necessary to power the camera on twice in succession. The first attempt ends in the camera saying "Wifi enabled". After that, I turn off the camera and as soon as all lights are off, I turn it on again. This time the camera also announces "Wifi connected" and I can verify that it is recording.
Because the camera needs two starts to get going, I found it more convenient to power the camera from my Ecoflow power station instead of the motorhome's fuse box via the HK3-C. My daily routine is like this. Camera on first time. After "Wifi enabled", camera off. When all light are off, camera on second time. After "Wifi connected", start app, connect to camera, stop recording. Go to settings, format memory card, start recording, exit app, disable wifi from phone. Then start the car. Complicated? Sure. But this has worked with perfect repeatability during our three-week trip to Sweden and Norway (from Finland).
I believe these are two separate bugs, one for each device (HK3-C and A139Pro). If I power my phone from the HK3-C, the phone is powered on or off the same way as the camera is, with regard to the BAT and ACC leads. And as regards the camera needing two start-ups, the behavior is the same regardless from the power source (fuse box via HK3-C or Ecoflow). What might cause the need for two start-ups? My best guess is that some big capacitor does not get quite enough charge during the first startup but does so during the second.
Anyone out there with similar problems?
