After researching a number affordable dash cams I settled on the Viofo A119V3 and Blackboxmycar as the vendor. I chose Blackboxmycar because of its customer service. This is my first Dashcam and I had a number of questions all of which were answered promptly and to my satisfaction by Katrina. Other vendors offered a slightly less expensive final cost but Katrina's service swayed my decision.
As to the camera itself I am very happy. In the last few days I have used it in temperatures of about -28ºC and it has performed flawlessly. The video quality is excellent with the CPL: clear, sharp and with good colours and contrast. Files are around 1.15 GB for 5 mins using 2560x1440 @30 fps H.264 or around 950 MB using H.265. The audio quality is quite acceptable.
Once you get the hang of using the Menu system it is quite easy to choose or change settings.
Also impressed with Viofo in that they seem to have thought of everything. The item included everything I could possibly need to mount and operate the camera even down to string to help remove the mounts in future if necessary.
Presently I am powering the camera via the cigarette lighter but am seriously considering hardwiring or using a portable power bank. I will then try the parking modes.
We have two cars and I had thought of moving the camera from one to the other so I purchased an additional GPS mount, that I have not yet tested. However I am now leaning towards buying 2nd A119V3 to avoid the hassle and to have a permanent neat installation in both cars.
