VIOFO A129 Pro Duo 4K Dual Dash Cam - Wifi GPS WDR Enhanced Night Vision Front & Rear Dash Cameras - 130° Wide Angle Compact 4K Wireless Dash Cams for Cars - Emergency Recording & Parking Modes

To start with, I was a little disappointed with this camera. Rather than give up on it and return it, I decided to opt for some extras and did some research on issues I was experiencing with it. Now I can honestly say it was worth it.1st of all, I wouldn’t recommend for the long term using the included cigarette lighter plug. Get the HK3 hardwire kit for it. Although it’s not plug and play, takes some research to know how to route the cables and get power to the camera, the hardwire kit allows the camera to be powered on when the ignition turns on, and enter a neat parking mode when you turn off the engine. Be warned the best way to tap into your cars power is with ‘fuse taps’ that don’t come with this kit. To be fair, I didn’t mind this as there are 3 different types of fuses in modern cars and the fuse taps cost less than a tenner for a pack of 4 on Amazon. As I say, it’s worth the extra work as the parking mode is awesome. I set it to a Timelapse feature and found that it captured the entire period of time my car was unattended (right through the night). Naturally this uses power from your car battery, but there’s a battery saver built into the kit that ensures the camera will record for as long as it can, leaving enough power to turn the engine over when you return to it. Although I’ve not needed it yet, I believe when the camera detects an impact while parked, it captures video from both front and rear cameras from before and after the bump and locks the video file from being overwritten.The quality from the front camera is exceptional when set to 4K. The quality of the recorded file is good enough to see the smallest of detail. The rear camera is full HD and is still clear enough to be able to see the faces of the drivers behind you, let alone their number plate. However I highly recommend you get the circular polarising filters for both front and rear modules. It does well to limit glare from sunlight or the headlamps of oncoming vehicles or the cars driving behind you. This gives you a better chance of reading number plates of careless drivers. I found the footage even in night driving was clear and the wide angle lenses means the cameras have a far better view of the road and surroundings than I do as the driver.The positioning of the camera needs to be behind the interior mirror to remain legal, but means you can’t see the display and interact with the dashcam. Thankfully with the above setup, I didn’t need to interact with the camera as it starts recording the moment I unlock the car and automatically switches to parking mode when I leave the car. Apart from adjusting settings, the only other time I needed to access the camera was when I wanted to lock a video file to save a moment in time from being overwritten (for example someone driving dangerously but not actually hitting me). Fumbling behind the interior mirror to locate the middle button is far too fiddly and dangerous so I opted to buy the additional Bluetooth button and stick it to the dashboard, well within view and my reach. Pairing it to the camera was almost too easy. I only needed to take the button out of the box and press and hold the button for three seconds. As long as the dashcam’s switched on, they pair immediately.The Wi-Fi was what really let the camera down for me initially. I downloaded the VIOFO app and signed in to the Wi-Fi signal the camera creates. The reliability was awful causing my phone to regularly disconnect and then wouldn’t reconnect to the camera. In an ideal world I wanted my iPhone to automatically connect to the dashcam when I enabled Wi-Fi, but there was no way that was happening. It seemed the only way to make the iPhone reconnect was to disconnect and reconnect power. This only resolved connection issues for a matter of minutes before the connection broke again. HOWEVER, while it was connected to my phone I noticed in the app settings the option to enable 5ghz Wi-Fi. I guess for compatibility reasons, the default Wi-Fi settings are set to 2.4ghz, but this is awful. Setting the camera to ‘5ghz only’ made the world of difference. Once reconnected, the connection to my iPhone was strong and didn’t break once. Downloading large video files (300MB each) to my camera roll took seconds too. What was more, the moment I switched on the Wi-Fi on the camera, my iPhone joined the Wi-Fi signal immediately. Now I can access recorded files quickly and easily without needing to remove the memory card.The last note I’d say is with the memory card itself. I’ve noticed with my setup (and about an hour of driving a day) that my 256gb memory card captures 24 hours of combined live video (when the engines running) and time lapse (when the car’s parked). This means I can decide to keep footage from any point in the last 24 hours. Really good for times when you don’t think a moment on your journey was worth keeping until later on. Obviously, more driving per day and a lower storage capacity card will mean less time to decide to keep footage. When selecting your memory card you MUST make sure you select a High Endurance card rated as Class 10 and UHS-I. If you don’t you WILL lose video clips. This is because the amount of data coming from a 4K camera and a 1080p camera at the same time needs the fastest memory cards. Slower memory cards won’t be able to write the data quick enough for the continuous stream of video coming in so you end up with video drop-outs.Overall, my assessment of this dashcam is that it is an incredibly good dashcam with the right accessories and the right settings enabled.

I purchased one of these as I'm sure most people would agree, we're all counting down before someone eventually hits us on the roads.This camera has front and rear, HD recording and came with what I see as a key feature, parking mode. I have no doubt that most people would drive into an unattended car and leave without giving details. This eases my mind as the parking function is pretty flawless in my experience.The HD recording quality makes it easy to read signs, registration plates and make out most details on vehicles or passing objects. The speed and GPS is also a nice touch, displaying your GPS coordinates, and if you download it to the app via the cameras WiFi, it even shows the real-time location on a map of the footage you're viewing!The only issue I had, which is more due to my car, was it interrupted the DAB signal, however from Futher investigation this is due to my cars manufacturer putting the aerial in an odd place.Hard wiring this dashcam on varies from car to car, however it's pretty straight forward and the hard wire kit that VIOFO makes is decent enough, it does the job and is fairly inexpensive.The VIOFO app works well for viewing/downloading footage, meaning no more removing the SD card to get the footage. I had a few issues when deleting a large amount of parking footage where the app would occasionally crash, however it doesn't really bother me enough to complain about it, it's nice to know it's actually recording the motion while I'm parking!Overall, if you're after a decent camera that's slightly more pricey that the competition, however performs beautifully, takes away the hassle of removing SD cards and records in genuine HD resolutions, I'd go for this anyday!

The media could not be loaded. I bought this dash cam to upgrade to a higher resolution camera with an additional rear camera. I have found the most useful feature to be the WiFi phone connection, making watching back videos and changing camera settings easy through the Viofo app.It was easy to install, using a sticky pad instead of a suction mount like my previous camera, to prevent any shake. The box has everything you need to do a professional "stealth" install, including a tool to remove trim to route cables, sticky cable guides, a long cable to run to the rear camera, a shorter cable and cigarette lighter adaptor, and spare sticky pads if you need to move the camera(s) (see picture). Note that an SD card is not included.I connected my phone to the camera using the app to help me initially position it using the live view, for both cameras. With the included GPS module, it can also log your position & speed and plays it back in the app with the video (see picture). You can also download individual videos to your phone.There is also the option for parking mode, where the camera can record before and after the g-sensor is triggered, using the Viofo HK3 hardwire adaptor (not included). Parking my car on the street each night, I will shortly be fitting this as an extra insurance policy!I am impressed with the video quality in both daylight and at night time. The picture is smooth and you can clearly see details like number plates in 4K, 2K or Full HD resolutions. I prefer setting the Wide Dynamic Range to improve exposure further in light & dark scenes, such as driving into the rising sun.Overall, it's a top notch product that is well thought out.
