Generally for everything in a normal car, voltage should be in the range of 12v. Just like all the voltage in a house is 230v.

BTW, get a piggy back fuse tap. This will ensure the ori fuse is not disturbed. Will not void if car still under warranty.

Wao, learn a new place for electronic goods.
Thank you

Another question, I see these fuse tap got 15v,12v etc. Is it important?
Fuse taps that support 12v and above is the one I'm looking for, right?

Also, at the hardwire kit has a voltage cut off toggle. I'll put it at 12V. Is it appropriate?

Thanks for your reply, I Googled and just want to confirm with you.

Can I put two ground wire together at the same terminal?
I attached the hardwire ground wire to the car's ground wire.

Hi guys,  please advise which dashcam to purchase? Budget 350

Viofo a119 v2
YI Nightscape Dash Camera
ddpai mini 3 pro
Other better option?

Does Viofo A129 has true parking mode like Thinkware now?
I am choosing one dual dashcam between A129 and F200

mean can last how many hours? still cannot long hrs eg 8-12+ hrs like thinkware?

what about Viofo A129 durability ok?
because most of time i park under sun just worry abit on this

just come across a new function on some power cables. 360degree radar detection. Instead of detecting motion in front of dashcam, the radar senses any movement in 5 meter radius. Seems like it can help to do some 'buffered' recordings.

anyone already using this?

should be any dashcam (ideally capacitor based).

cable like this: https://www.gearbest.com/obd-diagnostic-tools/pp_798467.html

sample video: https://www.youtube.com/watch?v=Vzr_DG8FU3c

basically its radar, sending out microwave to detect movements.

I got the same problem with my A129 Duo IR as well where the video will have some pink at the top side and not clear at the rear windshield line.

will try to adjust this. i currently setting it to mono mode. the color mode seems weird as the tree's green color turn purple 

@blurjoey,

  Appreciate your view on the Japanese made dashcam below, many thanks.

It does exist, its not a function inbuilt in the dashcam. Its the small radar box in the power cable that does the work whether to provide power or cut the power. Not sure about Korea, but this tech already exists in China (for at least 2 years), but not sure why its not widely used yet. Based on the description, its straightaway they did not mess up the conventional motion detect and radar detect.

The back color is really strange. Since this is issue from the cam itself, will viofo fix it?

anyone updated the buffered parking mode for viofo a129?

was told by sicurez.. they dont recommend the parking mode yet.. it seems that the power cut is not stable.. 

Need to calibrate the actual voltage  between vehicle battery & hardwire/camera. Wire resistance, voltage drop and component tolerance is the factor.

Just want to ask, if hardwire dashcam into the car electrical panel, will it void warranty?

just curious, could i remove the A129 IR rear cam and use the A119 dashcam as rear using the A129 IR rear cam micro cable to power

Measure car battery then measure input voltage into hardwire kit. See what is the difference? 1st try fiddle the cutoff setting based on measured input voltage of hardwire kit. If its at 12.35v then select 12.2v as cutoff and see how long the parking mode duration. If not long enough, set 12.0v

If the input voltage not stable, extra capacitor to stable the input voltage of the hardwire kit.

If input voltage measured is higher than car battery, add resistor to bring down the voltage close to measured car battery voltage.
