Which cars and drivers this camera suits
The COOAU D30S is a two-channel dash cam, so it mounts on your windshield and records the road ahead plus the cabin. That combination is what earns it a place in rideshare, taxi and delivery cars, where a passenger-facing view matters as much as the front one.
In dual mode it captures 2560 by 1440 from the front lens and 1080 from the inside lens at 30fps. The front view spans 170 degrees and the cabin lens covers 150, which is the field that decides whether a plate or a passenger is identifiable.
Run it as a single front camera instead and it records 3840 by 2160 at 25fps with the same 170-degree coverage. We'd consider that mode the better fit for a family car that only needs the road ahead.

What it will not do
Parking mode is not self-powered. The camera can start recording and lock footage after the engine is off, but the hardwire kit needed for that is sold separately, so budget for it if you want the parked monitoring.
Infrared cabin recording in complete darkness is black and white, not color. That is normal for IR, but it is worth knowing before you expect color detail from a night-time passenger clip.
Parking monitoring needs the separately sold hardwire kit.
IR cabin clips are black and white in the dark.

The camera is listed at $109.99, down from a typical price of $128.74 over the past 90 days, a saving of $18.75 or 15 percent.
We recommend weighing that discount against the cost of the microSD card and optional hardwire kit, since neither is included.
Mounting, storage and power to confirm
Before buying, check that you have a suitable windshield spot for the mount and that the cabin lens sits where it can see the interior without blocking your view. Confirm the camera's power connection fits your car's outlet or wiring plan.
The D30S does not include a memory card, so plan on a microSD card up to 256GB. Choose a card rated for dash cam use, and match its capacity to how long you need clips to stay available before the loop overwrites them.
Parking monitoring depends on the separate hardwire kit, so decide on that cabling at the same time you buy the camera rather than after.
Who should buy or skip this camera
We'd consider the D30S a strong pick for rideshare, taxi, delivery and commercial drivers who need documented front and cabin views. The infrared cabin recording, built-in GPS and no-subscription Wi-Fi app make it practical for a working car.
Skip it if you only wanted a single front camera with simple plug-in use. The two-lens setup, separate card and optional hardwire kit add steps you would not need.
