A129 Pro Duo 4K Dual Dash Cam 3840 x 2160P Ultra HD 4K Front and 1080P Rear Car WiFi Dash Camera 8MP Sensor GPS, Buffered Parking Mode, G-Sensor, Motion Detection, WDR, Loop Recording

I just bought an A129 Pro Duo to replace a Mini0906 (that thing was NOT one of the best cams like dashcamtalk claimed, but was a complete turd). === Let's get the negatives out of the way: On the A129 Pro Duo, the wifi feature is not broadcasting. I have tried 2.4GHz, 5GHz auto, and 5GHz forced to channel 40, and 5GHz forced to channel 36, and forced to 161; the SSID is never broadcast. As the MAC is not listed on the device (SHAME ON YOU, VIOFO!), I checked for new APs without an SSID and toggled wifi on and off, and no new MACs showed up, so it appears wifi is totally nonfunctional. It is otherwise a fantastic unit and I will be updating the review after I test night recording. I'm docking four stars as one of the reasons I bought this unit was wifi connectivity, and yet, I will be forced to pull the microsd card and use dashcamviewer to review footage. WTF, VIOFO? Fix the firmware please. Docking four stars for this. Also, Mini USB connectors? Why not USB-C? WTF? If you had used USB-C I could have prewired my car before the camera arrived. No volume setting for that infernal beep? Only On/OFF? I want the beep, I just don't want it to be eardrum-piercingly and nerve-gratingly loud. Do us a solid and give us a volume control for the beep, please, even if it's just "LOUD - MEDIUM - SOFT - OFF" And, why not a full kit which includes the hardwire kit, bluetooth remote and polarizing filters for both the front and rear cameras? OK, so with all the negatives that garnered a 1-star rating (only because I could not rate it zero) out of the way: === Positives 1. IT HAS A SCREEN! I skipped the Thinkware U1000 because even though it's objectively a better product, I wanted an integrated screen in case WiFi fails 2. DAY, FRONT Video quality is GREAT - at least in daylight (I will update this review over time). 3. It is easy to install 4. I like that there is a prewiring kit and a customizable parking mode (again, I will update this over time) 5. I like the visual recording, wifi, and mic LED indicators so I can check without having to wake up the screen 6. THANK YOU for implementing a screen timeout/"screen saver" feature. With most dashcams with screens, I need to manually turn the screen on and off. It's nice being able to tap a button and check status and let it time out and turn off on its own 7. I like that it's low profile and will not interfere with the visor as much as other models do. 8. I like the faint LED in the GPS mount; with the camera pulled off the mount, I can see that the GPS mount is receiving power 9. I like that WiFi can theoretically be toggled on/off with the overlay button (I say theoretically because WiFI actually doesn't work at all) 10. === Suggested improvements: * Switch over to all USB-C connectors * Support 1TB+ MicroSD cards * Allow your app to read MicroSD cards (since wifi doesn't work at all) * Implement a more active cooling scheme (phase changing heat pipe + maybe a fan) * Cloud recording/storage/vehicle tracker/locator connectivity: Cloud connectivity? (I'd subscribe for $5 to $10/month if you would archive 30+ days of coverage and allow easy merging/exporting from the cloud - this would be a nice recurring revenue stream for you) * Car locator feature (easy with GPS + cloud connectivity), with live view * Android Auto/Carplay integration to use rear channel as rearview mirror in infotainment for those of us who drive vehicles with useless back windows (sportscars, trucks, etc.) * a full kit which includes the hardwire kit, bluetooth remote and polarizing filters for both the front and rear cameras? * 3 channel support * higher quality sensors both front and rear <---<< * flip screen or android auto plugin to display either channel, use rear channel as supplemental rearview mirror view === Update day 2: I haven't recorded any footage for a review/sample video yet; I have been playing with parking mode settings and H.265 vs. H.264 and when I used H.265 and let parking mode run overnight and retrieved it in the morning, the camera was so hot it felt scalding - it hadn't been in the sun yet and the car interior was still cool. I did not have my IR thermometer handy so I did not actually measure it but I'd guess it was 70c at the very least. I was nervous letting it run in my Stinger so I disabled H.265 and reduced the video bitrate from maximum to high. Resolution maximum, WDR enabled, bitrate Maximum, EV = 0, rural/light suburban roads: Reviewing day footage on 4K screen w/Dashcam Viewer, I can easily read license plates of cars I am following. It is very difficult to find any frames where license tags of oncoming cars are readable. However, nighttime capture of registration tags are not readable. There is much blooming which of course obscures much of the scene. Rear channel, 1080p: Reviewing night footage, WDR enabled, bitrate Maximum, EV = 0, rural/light suburban roads: License tags of oncoming and following cars unreadable. Rear camera underexposed, difficult to make out detail on rural roads, cannot read following vehicles' plates (expected). Basically, meets expectations, provides some protection. == Exchange VIOFO want me to send the camera in for exchange. If it comes to that I'll do an Amazon exchange, returning the replacement box with the old camera since I had already installed the cables and tossed the package in recycling. I was hoping they'd come back with "Oh the firmware is buggy and here's an update" :-( On the bright side they respond fairly quickly. === Corrections to previous complaint: Time DOES appear to update automagically via GPS. === Update: === I received a replacement - I submitted a support ticket and they made the exhange super easy, with advance shipment of the dashcam. I am pleased to report that the wifi features work on the replacement camera. I am happy with the unit so far. The high temperature does concern me a bit though. === Update 15 months later: === Unit is under the extended warranty (I had to register it because the original came DOA). I was previously very happy with it but now the camera is freezing when powered through the integrated USB port. When powered through the GPS module/mount it functions fine - NO freezing, but the unit runs hotter and drains the battery quickly when powered through the GPS mount (this is a common problem discussed on messageboards, mentioned in a couple reviews here, etc.). Well, they tried to blame the USB cord (uh, no, I am using the hardwire kit), or the SD card (I already indicated I write/read tested the SD card using both Windows and Linux, so the SD card is not the problem), or parking mode (No, I will NOT turn off parking mode, as that is THE feature which prompted me to select this product). As such, all the way down to 1 star because their customer service has declined and they're obnoxiously patronizing with their canned responses. === Another update, a few days later === I just learned they are off for Chinese new year. With that in mind, I can only conclude they took the time to try to lend some support during the holiday so I am restoring my original rating of the product, and I humbly apologize to Viofo for my jumping to conclusions.

Update: I increased my previous review to 5-stars. Viofo reached out to me and had me update my firmware. So far, it's worked like a charm! Great support team! We had several conversation back-and-forth to problem solve the issue. I'm still using the dashcams and they've captured some amazing things! I've had this dash camera for a few months now and can honestly say I wish I would've purchased a different one. I haven't reached out to customer service yet. I wanted to provide my first impressions. This is not my first dash cam. My previous one was an expensive one that did the job. Quality was good. The best thing I like about my previous one was the reliability. I had it hard wired to my truck so when I started it, it came on, recorded my trip, and when I turned off my truck, it would stop recording. Super simple. I could pull the SD card out, pop it in my computer, and everything was there to review. Exactly what I want in a dash camera. This brings me to my VIOFO A129. I opted for this model because it has 2-channels, parking monitoring, and 4k. The features work great when the camera works. I find that it records when it wants to. I've use the app over WiFi to check my records and 75% of the time it doesn't record my driving. During a 10 minute drive, it'll restart at least once which isn't comforting. Sometimes it'll constantly restart then stop. Sometimes it'll start beeping ever 2 minutes while I'm driving. I've swapped SD cards thinking that might be the issue but after a day, it would repeat the restarting and beeping. So now, I constantly check that it's recording while driving for piece of mind which is not what I should be worried about for something that's supposed to provide piece of mind. In summary, I would look for something that works and does it well. Basically, set it and forget it until you need it.

The front cam is excellent and does the job well. For the rear cam the exposure needs to be adjusted if you have a window tint

I have been using my GoPro Hero 8 as my dashcam for many years, however, it gets too hot and turn itself off many times during the summer. Then I decided to get a solid and reasonable price dashcam instead. I have reviewed several dashcams online, and finally decided to get VIOFO 4k Duo from Amazon. First, it's under my budget of $300 (honestly I don't think $800 BV is worth it) Secondly, it's 4K and the quality is one of the best after few reviews over the years. Third the App is easy to use and there are lots of tutorial video online about this one, it's easy to learn and easy to operate. However, I quoted a price for dashcam installation in my Ford Ranger, the bodyshop I used to visit, asks for $300 for the whole process. After viewing several DIY videos on YouTube, I decided to do it myself. The good thing about Ford Ranger, it has a USB slot right behind the rear mirror, I could connect the dashcam using a short power cable, which is the same type of GoPro Hero 4. It only took about one-hour and I saved $300 easily! I tested it several times, the video quality is really good, especially under 4K, I could save the video directly from my iPhone and edit the video on the phone. I would say it's a really good deal if you are thinking about the protect your valuable car and win the claim after the accident. I would recommend it to others. Please note, don't hide your cable near the airbags as I shown in one of the pictures. I accident did it first and one mechanic told me that it would create more damage to the driver when the airbag pops out. So always hide the cable through the bottom section of the door frame.

This front and rear camera along with the gps module are easy to install. The cables are of good quality and the power adapter fits in the cigarette lighter. The quality of video both front and rear are very good.

شفت لها مقاطع كثير يجربون يحطونها في ظروف قاسيه وشغاله وتتحمل، دقتها بيرفكت ويستحسن شراء فلتر العدسه اللي يمنع الانعكاس لصورة افضل (خصوصاً في الليل) غير عن كذا ما شاء الله وضوحها عسل وتلقط اللوحات بالراحه.

If you’re reading this, this is the sign to get this. I've had these installed in my car for over 2 years. Got into a hit and run when my car was parked in a parking lot. Someone hit my car while backing up and hit my car, causing a small black scratch. Luckily I had parking mode and filed to my insurance and was found not at fault. My insurance paid for everything in 2 weeks. Shop bill was $2.5k CAD and about $500+ in Rental. I paid 0 thanks to this dash cam. I would've been driving around with a scratch on my car and the other person wouldn't of face any repercussions but they're now screwed since their insurance is categorizing them as high risk driver for not staying or reporting. I was thinking to myself, one of these days the dash cam will pay for itself. It sure has. This is your sign to get one. And yes, get yourself a viofo or this model. I've done countless research and this model is the standard one you should get. It’s 4k at the front and 1080p at the back but slow wifi chip. Get the newest model with better wifi chip so you can transfer files 10x faster, otherwise be prepared to sit in your car for a hot minute while transferring clips from your dash cam to your phone via app on wifi. 0 regrets.
