70mai Dash Cam A510 vs A500S: Which 2.7K Dash Cam Should You Buy?

Quick answer

Choose the 70mai A510 if you want the newer Sony STARVIS 2 sensor for cleaner night footage and future-proof parking features. Choose the A500S if you want proven 2.7K performance at a lower price and don't need the latest sensor. Both are single-channel 2.7K dash cams, so the real decision comes down to night clarity and budget.

If you're shopping for a 2.7K dash cam, the 70mai A510 and A500S are the two names that come up most often. They look similar on paper, but they're built for slightly different buyers: one prioritizes newer sensor tech, the other prioritizes value.

This comparison focuses on what actually changes your daily driving experience, like night recording, parking surveillance, and how each cam fits into a 70mai setup. We'll also flag where each one falls short so you can pick without second-guessing.

Sensor and image quality: STARVIS 2 vs the previous generation

The biggest difference between these two cameras is the image sensor. The 70mai A510 uses a Sony STARVIS 2 sensor, which is the same family used in newer 70mai models like the 4K M800 and 4K T800. STARVIS 2 sensors capture more light per pixel, which typically means brighter, cleaner footage when streetlights are dim or headlights cause glare.

The 70mai A500S uses the previous-generation sensor that made it a popular 2.7K dash cam for years. In daylight, both cameras produce sharp 2.7K footage that captures license plates and road detail. At night, the A510 has the edge in low-light clarity, while the A500S still performs well for most city driving.

• If most of your driving is daytime commuting, the A500S is usually enough.
• If you drive at night or on poorly lit roads, the A510's STARVIS 2 sensor is the safer pick.

Parking surveillance and 24-hour protection

Both cameras support parking surveillance when paired with a 70mai Hardwire Kit, which lets the dash cam keep recording while your car is parked. This is one of the most useful features for anyone who parks on the street or in a shared lot.

The A510 is designed to take advantage of newer 70mai parking features and software updates, while the A500S relies on the established parking mode it has had for years. If you want the most current parking feature set, the A510 is the better long-term choice. If basic hit-and-run protection is all you need, the A500S still does the job.

• A hardwire kit is required for parking mode on both models.
• Check your fuse box location before buying; installation difficulty varies by car.

Build, app, and everyday usability

Both dash cams use the 70mai app for Wi-Fi transfer, settings, and firmware updates, so the day-to-day experience is nearly identical. You mount the camera, connect your phone, and adjust settings without removing the memory card.

The A510 is the newer platform, so it tends to receive feature updates alongside 70mai's latest models. The A500S has a longer track record and a large user base, which means more community troubleshooting if you run into setup questions. Neither camera has a rear camera built in, so if you want front-and-rear coverage you'll need to add a compatible rear cam or step up to a dual-channel model.

• Use a 70mai Memory Card rated for dash cam write cycles to avoid corruption.
• Update firmware through the app before your first long drive.

Price and value: where the A500S still wins

The A500S typically costs less than the A510, and that gap matters if you're equipping more than one vehicle or buying your first dash cam. For budget-focused buyers, the A500S delivers the core job of a dash cam: clear 2.7K evidence of what happened.

The A510 asks for a bit more money in exchange for the newer sensor and a longer useful life as 70mai continues to update its software. If you keep cars for years and want the camera to stay current, that premium is easier to justify.

• Set a budget first, then decide if STARVIS 2 night performance is worth the difference.
• Watch for bundle deals that include a memory card or hardwire kit.

Trade-offs to weigh before you buy

• Night clarity vs price: The A510's Sony STARVIS 2 sensor captures more light for cleaner night footage, but it costs more than the A500S. Pay for the A510 if night driving is common; save with the A500S if you mostly drive in daylight.
• Newer platform vs proven track record: The A510 is on 70mai's newer hardware and software path, while the A500S has years of user feedback and stable firmware. Choose the A510 for longer software relevance; choose the A500S for a mature, well-documented experience.
• Cable and accessory compatibility: The A500S uses a Micro USB power cable, while the A510 does not appear on the compatible list for that cable, so accessories are not shared. Buy the correct hardwire kit and cable for your specific model to avoid returns.

Product facts that matter

• 70mai Dash Cam 4K M800 with Built-In eMMC, Dual Sony STARVIS 2, HDR Recording, 4G LTE & Compact Design: The M800 uses the Sony STARVIS 2 IMX678 sensor and pairs with the RC14 rear camera, which also uses a STARVIS 2 sensor. This shows the STARVIS 2 sensor family the A510 belongs to, and why that sensor generation is a meaningful step up for night recording.
• 70mai Rear Camera RC14 for Dash Cam 4K Omni/ M800: The RC14 is compatible with the 70mai Dash Cam 4K Omni and M800, and 70mai dash cams support two channels, so you cannot connect a rear camera and an interior camera at the same time. If you later want front-and-rear coverage, you need to plan your channel setup before buying, since rear and interior cameras compete for the same connection.
• 70mai Micro USB Power Cable for Dash Cam 1S/ 3/ A200/ A400/ A500S/ A800S/ M300/ S500/ Lite 2: This replacement Micro USB power cable is compatible with the A500S and other listed 70mai models, but not with the M500, Omni, A810, A510, 4K T800, 4K Omni, or 4K A800SE. The A500S uses a Micro USB power connection, while the A510 does not, so replacement cables and hardwire kits are not interchangeable between these two cameras.

Who should buy which

Best for

• Drivers who often drive at night or on dimly lit roads and want the newer Sony STARVIS 2 sensor.
• Buyers who want a 2.7K dash cam that will keep receiving 70mai software features.
• Rideshare or delivery drivers who want reliable parking surveillance with a hardwire kit.

Not for

• Shoppers on a tight budget who only need basic daytime 2.7K recording.
• Drivers who want a built-in rear camera without adding a separate rear cam.
• Anyone who needs a Micro USB replacement cable, since the A510 is not listed as compatible with the 70mai Micro USB Power Cable.

The 70mai A510 and A500S are both capable 2.7K dash cams, but they serve different buyers. Pick the A510 for newer STARVIS 2 night performance and a longer software runway. Pick the A500S if budget and proven reliability matter more than the latest sensor. Either way, add a proper memory card and consider a hardwire kit so you get the most from your camera.
