"As soon as I told her I had front and rear video, she got really excited. The adjuster of the at fault car was less excited about my video but still wanted a copy. My video also proved the car behind me was not at all at fault so I saved her some hassle too. ... I had a front and rear dashcam which all the insurance companies were excited to see. All of them wanted copies of the video. It proved with zero doubt that the first 3 cars were not at all at fault."
"A129 is plenty good enough ... even a fuzzy picture with front and rear coverage is enough to prove fault."
"The shock of the crash did trigger the g sensor so i have the footage of my car on its side and the recovery process afterwards, but not the actual wreck itself."

"For what it ’s worth i have ZERO car experience and I got the viofo front and rear cam and used the donggar adapter to power it off the rain sensor behind the rear view mirror. ... I watched maybe 2 tutorials, went slow, and was able to get everything in place in well under an hour with no issues. ... Highly recommend, super easy to do."
"I used a dongar pro, so power was super easy."
"No problem easy install."

"I have the viofo duo. Would not recommend because mine does overheat. ... I was in an accident end of july 2 years ago and it did not capture it. ... The shock of the crash did trigger the g sensor so i have the footage of my car on its side and the recovery process afterwards, but not the actual wreck itself. ... When its not overheated you have tl remember to reset it for it to start filming again. Very frustrating. ... It works good in the winter months but ive left it unplugged since about march ... All i know is it works fine in the winter but anything over 90 i have to reset it everytime i turn the car on. And it wont turn on and let me reset it until its cooled off ... I pretty much gave up on it after months of it not working right."

"Also, the WiFi is sloooooooooow. ... It would basically take all night to pull all the video from the day."
"when WiFi is enabled, it overheats in the summer."
"I hate having to remove the card to bring it inside and I’m forever forgetting it in my computer."

"I don't trust them anymore with their built in capacitors that died."
"The rear camera died at 13 months which stopped the front from recording. ... They wanted me to pay $40 for a replacement rear cam though it was still in warranty."

"I wasn’t happy with how hard I had to hit the car to get it to trigger. ... I feel like it could easily get door dinged and it wouldn’t save the footage."
"My problem is it records too much. ... It’s triggered by any motion so you need a really large card for it to be practical."
"it's very inconsistent as far as recording when you need it to"

"Hardwiring is a bit of a PITA ... Mine is tucked into the footwell under the dash on the passenger side and has the little mini fuses, which, combined, made it pretty difficult to wrap the power wire and plug the fuse back in."
"The biggest hurdle was getting the wired connection from the front camera to the rear one"
"tho I did need to redo the wiring"
