70mai M800 vs Thinkware ARC 700: Which Recording and Parking Setup Fits Your Car?

Pick by storage workflow first: the M800 set lists built-in 128GB eMMC, while the ARC 700 Front & Rear kit includes a removable 64GB microSD and supports cards up to 256GB. Both have documented parked-recording options; compare the power route you want and verify the exact M800 seller bundle's cable contents before ordering.

The buying question

Would built-in eMMC or removable microSD matter more, and which documented parking-power route fits the car and preferred installation?

The M800 uses built-in eMMC and supports a documented OBD-II accessory path, while the ARC 700 Front & Rear kit lists a removable card and hardwiring cable in its box; compare the parking modes and power requirements against the setup you want.

Quick verdict

Choose Thinkware ARC 700 Front & Rear (TW-ARC700D) if

  • You prefer removable microSD storage and want the exact Front & Rear kit’s included 64GB card.
  • You want the exact ARC 700 Front & Rear package page to list a hardwiring cable alongside its 12V power cable.

When the recommendation changes
  • If you prefer removable media that can be changed independently of built-in camera storage, the ARC 700 package’s included 64GB card and support for cards up to 256GB may fit that workflow better. Capacity alone is not a recording-time comparison.
  • If the exact M800 seller bundle includes the parking-power accessory you plan to use, that may change which package is simpler to install; check the listing contents rather than assuming the accessory is included.

The differences that matter

Storage And Recording Workflow

70mai M800 4K Front & Rear Set (RC14, 128GB eMMC)

Built-in 128GB eMMC storage is listed for the M800 Premium Set.[1]

Thinkware ARC 700 Front & Rear (TW-ARC700D)

The exact ARC 700 Front & Rear bundle lists an included 64GB microSD card; official ARC 700 information supports microSD cards up to 256GB.[4, 3]

What this changes: Choose built-in eMMC if you prefer storage integrated into the camera; choose the ARC 700 kit if you prefer removable microSD storage and its listed included 64GB card. That card is already in this exact package, so this is a storage-handling choice, not a choice about avoiding an initial card purchase. Capacity alone is not a recording-time comparison.[1, 4, 3]

The better fit depends on your priorities

Parking Power And Accessories

70mai M800 4K Front & Rear Set (RC14, 128GB eMMC)

The M800 Premium Set page lists 24-hour parking monitoring and front/rear time-lapse; 70mai says its OBD-II parking-surveillance cable is compatible with all its dash cams. Remote 4G monitoring requires a separately sold 4G hardwire kit; verify current U.S. kit compatibility, service or plan requirements, and coverage before relying on remote access.[1, 2]

Thinkware ARC 700 Front & Rear (TW-ARC700D)

ARC 700 supports motion/impact, time-lapse and energy-saving parking modes that require a hardwire or OBD-II power cable. The exact Front & Rear kit page lists a hardwiring cable and 12V power cable.[3, 4]

What this changes: Choose based on the parking mode and power route you intend to use; verify the selected M800 seller package’s cable contents rather than assuming an unlisted item is missing. If remote 4G access matters, separately verify current U.S. kit compatibility and service conditions for your location.[1, 2, 3, 4]

The better fit depends on your priorities

Best for your routine

Built-in versus removable recording storage

The better fit depends on your priorities

The M800 set lists built-in eMMC; the ARC 700 kit lists a removable 64GB card and the camera supports larger microSD cards. Choose the workflow you prefer rather than treating capacity alone as footage-time proof.

Planning parked recording and the required power accessories

The better fit depends on your priorities

Both manufacturers document parked-recording modes. The ARC 700’s exact Front & Rear kit lists a hardwiring cable; 70mai documents an OBD-II parking cable compatible with its dash cams, while M800 remote 4G requires a separate kit. Verify the M800 offer contents and, if remote access matters, current U.S. kit compatibility and service conditions.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

A higher current offer should be weighed against the storage workflow, exact included accessories and parking setup you will use; no fixed dollar premium is embedded here.

Available price history does not establish a historical low or when to buy; compare the current exact offers, seller and bundle contents when shopping.

Limitations

  • The exact M800 seller offer’s ordinary parking-power cable contents are not enumerated on the manufacturer’s product page; verify the selected listing’s box contents.
  • The storage capacities do not by themselves determine recording duration; video settings and recording behavior matter.
  • This is a source-based feature and setup comparison, not a Pickoryx recording, image-quality, heat, reliability or parking-detection test.
  • The 70mai page says remote 4G monitoring needs a separately sold kit but does not establish current U.S. service availability, plan requirements, or coverage for every location; verify these before relying on remote access.
  • The Thinkware pages checked here do not establish whether ARC 700 offers comparable remote cellular monitoring; no absence is inferred.

Questions shoppers ask

Does the ARC 700 Front & Rear package include a memory card?

The Thinkware US Store's exact Front & Rear box list includes a 64GB microSD card. The ARC 700 supports microSD cards up to 256GB, so buyers who want removable storage can also review the card-capacity guidance before choosing a replacement.

Can either camera record while parked?

Both manufacturers document parking modes. The M800 page lists 24-hour parking monitoring and time-lapse; 70mai also documents an OBD-II parking cable for its dash cams. ARC 700 parking modes require hardwire or OBD-II power, and the exact Front & Rear kit lists a hardwiring cable. Check your vehicle and the exact M800 offer contents before installation.

What does the M800's 4G option add?

70mai says M800 remote monitoring requires a separately sold 4G hardwire kit. Before relying on that feature, check that the kit is currently compatible with the U.S. M800 set and confirm any service or plan requirements and coverage for your location. Buying the hardware alone does not establish remote-service availability; this is not evidence that the ARC 700 lacks other remote features.
