VIOFOA129 Plus Duo 2K Dual Dash Cam - Wifi GPS HDR Enhanced Night Vision Front & Rear Dash Cameras - 140° Wide Angle Compact Wireless Dash Cams for Cars - Emergency Recording & Parking Modes

I spent a good few days researching dashcams before settling on this one. It's a vast and quite bewlidering market to explore with many makes / models / features to consider, so I sat down and made a list of what I wanted from a dashcam, it went something like this:1) Two cameras, 1 front and 1rear2) Good picture quality, based not just on the quoted advert numbers but by finding the cameras of interest on You Tube and seeing for myself how good / bad the footage was.3) No Lith Ion battery inside but a capacitor instead.4) Small and compact.5) Must be detachable from the windscreen6) Must have GPS co-ordinates, Time / Date, Speed and the ability to have the Reg Number stamped on recorded footage .... Reg number is handy if you get yours cloned, there's lots of it about now with ULEZ schemes etc going on and it can help prove the car was elsewhere at the time if you get a fine dropping through the letterbox that's not yours.7) Easy and intuitive to use - I'm a digital Idiot so the easier the better,8) Must have good user reviewsThe Viofo A129 Plus Duo ticked all of the above boxes for me so I sent off for one via Amazon and it arrived within 48 hours as stated. I'm not having the hard wire kit yet because I don't want the parking feature until I've discovered how it'll affect the 12v battery. My car's a self charging hybrid and I need to find out if the camera being permanently live will have any adverse effects, so for now it's just plugged into the cigarette lighter.Fitting the camera was a breeze, it was all installed in about 1/2 hour with all the wires hidden from view, apart from where they go into the cameras of course. The supplied cables are plenty long enough for most normal cars I imagine, my car is an average size hatchback (Toyota Corolla) and there was ample to go to the rear camera, in fact there's now a fair bit of excess wire hidden behind the headlining.Setting up the Wi-Fi was really easy as well, so I was soon into the menu putting in the reg number to display on the video footage.Once everything was done I went out for a run. The camera comes on automatically as soon as the car's "Power" button is pressed and the screen lights up in about 10 seconds, it stays on for around 3 mins then goes out so you can forget all about it (it can be set differently in the menu). The two red LEDs remain lit, the left hand one flashes if recording stops for any reason and is accompanied by a "Beeping sound". The other red LED is for the microphone which can be turned off if not required and that light will then go outTo say I was impressed with the picture quality of the Viofo would be an understatement, it really is top notch. We'd had a terrific rainstorm before I went out on the test run, but the clouds had parted and the late afternoon sun was directly in front and also reflecting off the wet road. I honestly didn't expect any decent footage at all from that bit, but when I got home and popped the pics onto my PC monitors I was amazed at how well the camera had coped with the harsh light, it was incredible and there was very little lens flare. On the way back home the sun was shining onto the rear camera and that had also coped exceptionally well with it. I use two large photo editing monitors and the videos from both cameras are pin sharp on them.Gripes? Well there aren't many really - so far - apart from maybe Viofo not including a micro SD card in the box, also they don't even appear to be including an SD card reader / adaptor anymore - which they used to do. Not a major problem but just a bit "penny pinching" really, so you will have to budget for buying the SD as well and Viofo spec high class ones which aren't that cheap. I bought a 128gb one for a good price via an Amazon deal which should last best part of a week or two before it overwrites.To sum up - these are simply brilliant little cameras, they're very small and unobtrusive but they feel very well made and for the price they're excellent value. There are some good videos on You Tube on the set up and fitting of the A129 Plus Duo, as well as quite a few video samples. Viofo recommend the SD card is formatted every month, this can be done in situ. I think you can set up a format reminder via a beep on the front cam, I seem to recall seeing it somewhere. I've set a reminder in my phone instead as I'm more likely to see that.The cameras have been fitted for about 2 weeks now but I'll follow up this review in a couple of months to report how they're doing.

Currently writing this review after 1 day of use; will update further if anything goes wrong but so far it's great. Picture quality on front camera is brilliant, the 2k at 30fps is plenty smooth enough and captures a lot of detail so if an accident occurred it should easily be able to pick up details of the road and other vehicles. The back camera has a slightly less clear picture as you'd expect being a lower resolution but it's still very capable. I've had another cheap dash cam before that claimed to be full HD but it was nowhere near as clear as this. Wiring this up was a small challenge (using sticky tape to stick the wires to various bits of the interior), there are a few useful stick on cable clips included but could do with a few more being provided. The instructions weren't fully clear as to what was what but good enough to figure out. There were 2 screen protector like films which I presumed you place on your windscreens and then attach the camera on top of those. I found the supplied sticky pads on the cameras used to secure each camera to the film were not great - one of them kept falling down as soon as you'd stick it back up. My solution was to buy some heavy duty Velcro tape and attach some to the screen protector film and the corresponding to the camera; this appears to have held much better and should make it easier to adjust position in future. The cables could have been a bit better designed, they stick out from the tops of the cameras meaning you have to allow room above the camera for the cable - so each camera sits a little lower in the view that I'd have ideally liked but only by an inch or so. Operation seems fairly simple, primarily the cameras turn on when powered up and they start recording instantly but there's various things you can configure such as the timestamp and speedometer stamp on recording (available via the GPS unit on the back of the front camera). I've not really tried out any of the more complex features as my car is usually parked securely on my drive or I'll try to park publicly where there is CCTV, mainly I just want to be covered against the idiotic drivers on the road.All in all I'm pleased with the purchase; far better than the ~£50 camera I bought a few years ago and it's of course great to have front and back coverage. People don't tend to get right up your backside when they notice the camera. Of course sometimes these can even lower your insurance premiums so might end up being a saving in long term (especially if you're involved in accident where the fault is up for debate).

Works well. Infinitely better and more reliable than the Nextbase dashcams I used previously. My only criticism is that the buttons are too small and they are not intuitively placed. I've had the cameras over a year now and I still have to get the manual out every time I want to reformat the card or view clips because it's such a fiddly business to operate the cameras. I always use the app on my phone to change settings and reformat, but even then it's fiddly to operate the buttons to connect the cameras to the app. The font on the manual is tiny. Viofo just need to tweak things a bit to get a great product.
