I have a VIOFO 3 channel camera - 4k front, 1080p rear and interior. I highly rate it - very high quality sensor for the 4k camera, especially at night. Interior camera has IR LED's so works very well at night also. The wiring is easy for the interior camera as you're generally mounting it right next to the dashcam (or within a foot or so).

Ben destijds zelf ook voor de A139 gegaan, 3 channels, en dit dan met een losse accu tussen mijn auto accu en de camera in, al maakt dit het wel een heel stuk duurder, maar was voor mijn gebruik wel een stuk fijner. Destijds was de 139 1 van de weinige met de starvis 2 sensor, ben wel benieuwd of er niet toevallig inmiddels betere keuzes zijn.

Do yourself a favor and buy the Viofo A229 or 339 on Amazon when they go on sale.

I’ve had the VIOFO 139 Pro front and rear for a couple of years now and it’s been flawless. Easy to connect to it with the phone app and view or download clips. Has parking mode if you hardwire it with movement sensor and G-sensor plus time lapse recording.

I use Viofo (specifically the A139 Pro but there are other options) and it's great. I have mine plugged into an external battery pack because I don't want to hardwire it. There's actually tons of good options now, dashcam technology has come a long way in recent years and there are some great quality cameras. There's also r/Dashcam for sample videos.

Most dashcam enthusiasts recommend Viofo and Thinkware with the STARVIS2 sensor for the dash cam of choice. You may have to look into BlackVue for push notifications, as they have some cloud services. I personally run a Viofo A139 Pro hardwired into a Powercell 8 external battery that is hardwired into driver side fusebox for parking mode. The setup is about $500-600.

Viofo or Thinkware, and any dashcam equipped with the Starvis2 sensor, are the go-to for dash cam enthusiasts when it comes to picture quality and license plate reading. The most optimal parking mode setup, but most pricey, is a 2/3ch dash cam hardwired into an external LiFePo4 battery that is then hardwired to driver/passenger fuse box. This setup will provide parking mode and reduce the wear and tear on your 12v battery. If parking mode isn't something you need, you can just to the 12v accessory socket for normal driving dash cam use. I used Viofo A139 Pro and have installed Viofo A229 Pro on family's car.

Viofo A139 Pro (~250) + Powercell 8 external battery (~350) For front/back 4k images + parking mode up to 8-10 hours without wear and tear on the 12v battery.
