Viofo A329T (unboxing & first impressions) (Sony Starvis 2 IMX678, Wi-Fi 6/GPS, HDR, Novatek NT98530, 4K front + 2.5K telephoto + 2.5K rear, HDR all)

@lufa6977 I think of doing it like this in my van. Are you using two BT buttons?

@viofo It would be nice if two (or more) main cams could sync by bt/wifi (date, time, crash, recording, etc.).

No, not using BT button. When I had the A229 Pro on the rear window, I used the voice commands to enable WiFi, take a photo, etc. I never had a problem with the voice feature working with the rear camera. The only 'adverse event' from voice commands are times when turning on Wifi, both dash cams will respond. Not a issue per se, I just need to make sure I hear both dash cams acknowledge the wifi is off when I command it to do so.

The HK4 module is near the rear camera, all I did was to extend the input power side wires between the module and the fuse panel. Very easy to do, I soldered 18-3 AWG to the module board, but you can use 20 AWG. 20 AWG is a little easier to work with, but has a bit more voltage drop over the 16 feet I needed to pull in, so I went with 18 AWG. I would almost bet that VIOFO would build you an HK4/HK5 with an extended power lead if they were asked. VIOFO is very good about custom cable and customer satisfaction.

The voltage drop becomes a consideration due to the voltage settings on the module, you will want as much of that 12VDC reaching the module as you can have.

We will have a new hardwire kit cable, users can easily extend the cable by DIY.

With new hardwire kit will be possible to display input system voltage in Text Stamp like Thinkware, BlackVue, Vueroid, GNET, etc?
Would this help diagnose power starvation malfunctions?

Interesting question.

Viofo has given you a thumbs up, so maybe it will, but a lot of the "power starvation malfunctions" are due to low voltage on the 5V, not the 13.6V that you are showing. The 13.6V is useful for watching the battery state of charge, a low voltage there is not a malfunction, it is simply an empty battery, or your alternator not working, which would be a malfunction!
 
I’m so dumb. lol
I meant to say parking mode malfunctions, (like shutting down prematurely).
It will be nice to see the input system voltage steadily drop on the recorded footage to confirm the camera is shutting down correctly based on the desired low voltage cutoff when connected to the vehicle’s starter battery.
Or when the low voltage cutoff is disabled when connected to a dash cam battery pack.

It will also be interesting to see why Viofo has decided to add a voltage monitor to their hardwire kit, I don't expect the main reason to be so that you can watch the display... assuming that the thumbs up is actually an acknowledgment of course!

No more switch on hardwire kit?
Now a firmware setting?

Vantrue's OBDII hardwire kit has a digital voltage readout. It would be cool if Viofo had a digital readout somewhere either displayed on Camera or in the Software.

Looks a bit difficult to read, ODB sockets are not located in a convenient place for reading a display!

On the camera would be better, but I don't think you need to read it very often, so on the diagnostics display in the phone app would be a good place.

The cord is long enough to mount in a visible place. However, putting the voltage readout on the camera or accessible via the app would be a nice touch.

Vantrue sent me their OBDII cord as their 3 wire hardwire kit is too short for their grounding wire. You literally have about 6-8CM of cord length.
 
The only voltage/amp reading I would figure to be of value, to me anyway, would be the supply side 5vdc/2a between the regulator and the dash cam. But, I can get that now by sticking a Pluggable USB-C voltage/amp reader inline. I have zippo need for that info to appear on the video itself, or the dash cam screen.

I disagree.

1. A readout tells you the battery's current voltage.

2. You can gauge how long the camera will run until it hits X voltage (12.2, 12.0, 11.8).

3. This is great if you run multiple dashcams to calculate about how long they will last if hardwired.

Thank you for this, the mind boggles at all the options, but this is a strong strategy by Viofo though 🙂.

The only one that I'm trying to wrap my head around is the A329WW, who would need two rear waterproof cams..

maybe a truck or someone with a trailer
