I love watching the evolution of gadgets.

I’ve been around long enough to remember a time before we had a lot of the gadgets we take for granted today, like smartphones or laptops and today’s topic, dash cams.

Today we are looking at two dash cams, the 4K A810S from 70mai and A329S from VIOFO.

Both offer 4K recording and tons of other features.

The 70mai would make a great first dash cam if you are a first-time buyer, while the VIOFO is aimed at the power user who needs to customize their system.

This isn’t a comprehensive review, but these are two dash cams I really like, and hopefully you’ll read enough about them to want to dive into the research for yourself.

70mai Dash Cam 4K A810S ($199.99, 70mai.com)

This model is an updated version of the A810 — the A810S includes front and rear cameras. The front records in 4K while the rear is 1080p.

You can choose from two types of rear camera — interior, mounted in the back window, or exterior, mounted outside near your back license plate.

The main Dash Cam has a 4K sensor that’s designed to adapt to changing lighting conditions. It uses an advanced license plate algorithm to prioritize recording the image of license plates in your videos. It uses a very good Sony Starvis 2 sensor.

It also has Night Owl Vision for great image capture at night and Lumi Vision for better image capture in near-total darkness for parking surveillance.

The A810S also has AI motion detection that can detect and notify you of suspicious activity around your parked vehicle. Once activity is noticed, the cameras will begin recording for 30 seconds.

The system records to an included 128-gigabyte microSD card and is constantly recording when you drive. It has the ability to detect collisions, and it will automatically buffer and save the video three minutes before and 30 seconds after impact.

You can also set the sensitivity of the parking sensor that notifies you and records your car’s surroundings when it’s jostled while parked. Instead of a traditional battery, the A810S uses a supercapacitor that can better handle the hot conditions inside your parked car all summer.

The kit comes with a 12v plug adapter and cables for connecting the cameras. There is also an optional hard-wire kit to tap directly into your car’s fuse box for power. The hardwire kit is necessary for the parking surveillance features.

There is also a 4G modem kit that requires a SIM card if you’d like to enable features like live remote monitoring from the app or real-time battery voltage information, live route tracking and Find My Car. With the 4G option, you can turn on your car’s cameras for a peek, even if you’re across the country.

The unit has GPS and Wi-Fi to directly connect to your smartphone to offload videos. You can also pop out the SD card and access the video through your computer.

VIOFO A329S 3-channel 4K Dash Cam (starting at $329.99, VIOFO.com)

I’ve never seen a dash cam as configurable as the VIOFO A329S.

You can buy the A329S by itself as a front-facing dash cam for $329.99 (VIOFO.com).

You can buy the A329S along with a rear-facing camera, which is called a 2-channel system

For $359 and you can buy a 3-channel system with a front, rear and interior camera for $469.

You can also get a configuration with a waterproof rear camera (or two) designed to be mounted outside.

You can also configure how long you’d like the cable that runs to those rear cameras. The cable lengths vary from 6 meters to 20 meters, so this is a great dash cam for your car or for even the longest motorhomes.

The main dash cam has a 4K Sony Starvis 2 sensor and the other cameras have 2K Starvis 2 sensors. They all have HDR (high dynamic range) exposure control for capturing clear images of license plates.

There’s also an optional 4x optical zoom telephoto camera.

The A329S has everything you’d want from a top-of-the-line dash cam, including Wi-Fi 6, GPS, voice control, multiplex video (combining the images of all three cameras into one video), low power impact detection and hybrid parking recording.

It also has a USB-C port for connecting an up to 4 terabyte SSD for large amounts of recording storage. The main camera storage is via microSD. The camera can use that USB-C port to connect a phone or computer to easily offload your videos.

The SSD option requires the optional hardwire adapter, which also is needed to monitor your vehicle when it’s parked and turned off. You’ll also get low battery protection, which can turn things off if your battery reaches a low power state or after a certain amount of time.

You can set up hybrid parking recording that shoots a 1 frame-per-second timelapse and then records a video clip in the event of an impact while you’re parked.

The camera system ships with a 45-watt car charger that can power the A329S and has power left over to power up your phone. The interior and rear cameras connect via ultra-slim coax cable to the main camera. Data and power are handled through the same cable.

There’s also a battery-powered Bluetooth remote you can place on your dashboard to turn the microphone on or off, turn Wi-Fi on or off and even a big button to press to mark and lock a video clip if you see something you want to tag and save.
