💡 Core Features & How It Works
The system continuously records everything happening around your car and manages files automatically. [1, 2]
| Feature | How It Works & What It Does |
|---|---|
| Dual Full HD Recording | The front camera records at a smooth 60 frames per second (FPS) to minimize motion blur, while the rear camera records at 30 FPS. Both feature premium Sony STARVIS image sensors for enhanced clarity at night. |
| Loop Recording | Video clips are saved in short increments (usually 1 minute) directly to your 16GB microSD card. Once full, the newest footage automatically overwrites the oldest, ensuring it never stops recording. |
| Intelligent Event Filtering | A built-in G-Sensor automatically detects impacts or sudden speed shifts while driving. It separates these "Event" files into a protected folder so they aren't accidentally overwritten by the loop cycle. |
| Parking Mode Protection | When hardwired, the camera enters Parking Mode after being stationary for 5 minutes. It saves video only when it catches physical impacts or visual motion near your vehicle. |
| BlackVue Over-the-Cloud | If the camera connects to an active mobile hotspot or car-embedded internet, you can use the BlackVue Cloud app to view live remote footage, track GPS location, and receive push notifications on your phone if your parked car is hit. |
| Proximity Sensor | A touchless sensor on the side allows you to toggle audio recording on or off just by waving your hand next to it. |
Would you like assistance finding a mobile hotspot solution for the Cloud features, or do you need help troubleshooting a connection between the dashcam and your smartphone app?
explain -- If the camera connects to an active mobile hotspot or car-embedded internet, you can use the BlackVue Cloud app to view live remote footage, track GPS location, and receive push notifications on your phone if your parked car is hit.
The BlackVue Cloud feature allows your dashcam to act like a smart home security camera for your vehicle, enabling you to check on your car from anywhere in the world.
1. How the Connection Works
The dashcam itself does not have a cellular SIM card slot or built-in internet. It needs an outside source to bridge the gap to the internet:
- The Bridge: Your car needs to have an active Wi-Fi signal while parked. This can come from a built-in vehicle Wi-Fi hotspot (like OnStar), a dedicated plug-in OBD-II LTE hotspot, or a portable battery-powered mobile hotspot left in the glovebox.
- The Handshake: You program your mobile hotspot's Wi-Fi network name and password into the dashcam using the BlackVue App. Whenever the camera is powered on, it automatically logs into that hotspot and connects to the BlackVue Cloud servers.
2. What This Enables You to Do
Once the dashcam has an active internet connection, you can open the mobile app on your smartphone from your home, office, or while traveling to use these features:
- Remote Live View: You can pull up a live video feed from both your front and rear cameras to see exactly what is happening around your vehicle in real-time.
- Instant Impact Push Notifications: If someone hits your parked car, the camera’s internal sensor detects the vibration. It instantly sends an alert straight to your phone saying "Impact detected in Parking Mode," allowing you to check the live feed immediately.
- Live GPS Tracking: You can view a live map showing your car’s exact location and driving speed, which is helpful if someone else is driving your vehicle or if it is being towed.
- Cloud Backup: The camera can automatically upload critical "Event" videos (like a collision) directly to your secure cloud storage space, ensuring the evidence is safe even if someone steals or damages the physical dashcam.

how many minutes of driving are expected with the 16 GB memory card ? is that the maximum size memory card ?
With the standard 16 GB memory card, you can expect approximately 85 minutes (1 hour and 25 minutes) of continuous driving footage before the camera completely fills the card and begins loop-recording (overwriting your oldest files). [1]
Storage Breakdown & Limits
- No, 16 GB is not the maximum size. It is simply the entry-level capacity that shipped in the box with that specific model SKU.
- The BlackVue DR750S-2CH officially supports microSD cards up to 256 GB. [1, 2]
Upgrading your storage extends your recording window significantly before older data is recycled:
| Memory Card Size | Estimated Driving Recording Time (Highest Quality Setting) |
|---|---|
| 16 GB (Included) | ~1 Hour 25 Minutes |
| 32 GB | ~2 Hours 50 Minutes |
| 64 GB | ~5 Hours 40 Minutes |
| 128 GB | ~11 Hours 20 Minutes |
| 256 GB (Maximum Supported) | ~22 Hours 40 Minutes |
Important Upgrade Tip
Because dashcams write data continuously, they burn through retail flash storage quickly. If you purchase an upgraded card, ensure it is labeled as "High Endurance" (specifically designed for security loops). Once inserted, use the physical Wi-Fi button on the side of the camera (hold until a voice prompt sounds) to format the new card directly inside the dashcam. [1, 2, 3]
Would you like help finding a compatible High Endurance microSD card online, or instructions on how to use the BlackVue Viewer app to format a larger card on your computer?
help finding a compatible High Endurance microSD card online
Compatible High Endurance microSD cards for your BlackVue DR750S-2CH are available through several retailers below. Because BlackVue cameras are notorious for throwing error codes with standard memory cards (like the SanDisk Ultra series), it is highly recommended to stick with true High Endurance MLC-based cards or official BlackVue OEM cards to prevent corrupt footage. [1]
Highly Compatible High Endurance Options

- Performance: V30 and U3 rated speed classes perfectly handle smooth dual-channel Full HD streams without dropped frames.
- Purchase: Available across retailers like B&H Photo Video and OfficeSupply.
- Durability: Built with enterprise-grade NAND flash memory to survive extreme cabin temperatures ranging from -25°C to 85°C.
- Performance: Supports real-time video looping up to 43,800 hours for the 128GB tier.
- Purchase: Offered online via Adorama and Newegg.
- Durability: The official manufacturer card featuring specialized internal wear-leveling control to guarantee zero system error codes.
- Performance: Fully certified to support hardware-level file recovery structures unique to BlackVue firmwares.
- Purchase: Pick up official sizes up to 256GB at The Dashcam Store or browse Dashcam Bros. [1, 2, 3, 4]
Would you prefer to look at 128GB or 256GB sizes to optimize your recording hours, or do you need the specific formatting steps using the camera buttons?
is there a way to view the rear camera live (like a rear-view mirror) ?
No, you cannot use the BlackVue DR750S-2CH as a real-time, continuous rear-view mirror replacement while driving.
While the hardware captures excellent rear footage, the system is not designed to function as an active electronic mirror for several practical reasons:
1. App Limitations & Streaming Lag
You can view a live feed of the rear camera by opening the BlackVue App, selecting Live View, and tapping the Rear button. However, this is meant only for checking the camera angle or viewing a brief status. Running a continuous stream onto your phone while driving will drain your phone battery, cause the camera's Wi-Fi chip to overheat, and introduce a slight video transmission lag that makes it unsafe for real-time traffic monitoring. [1, 2, 3, 4, 5, 6]
2. Cloud Data Caps
If you attempt to stream the rear camera while driving via BlackVue Cloud (using an in-car hotspot), the free BlackVue tier limits you to just 10 minutes of live viewing per day. [1]
3. The Best Alternative: Mirror Dashcams
If your primary goal is to have a digital screen overlaying your physical mirror that feeds a live, lag-free rear video stream, you need a different style of hardware known as a Mirror Dashcam. These systems completely replace or strap onto your existing rear-view mirror and are specifically wired to display continuous, real-time rearview footage. [1]
Are you trying to overcome a blind spot / blocked rear window in your vehicle, or were you just checking to see how the smartphone app behaves while driving?
is there an option to manually trigger 'accident' or event has occurred to secure the file, or send to cloud ?
Yes, you can manually trigger an event recording to secure a video clip and protect it from being overwritten.
The BlackVue DR750S-2CH provides a quick, touch-free way to do this while you are driving:
1. The Touchless Proximity Sensor
On the left side of the front camera (the side facing away from the windshield, where the LED lights are), there is a touchless proximity sensor.
- How to use it: Simply wave your hand within about an inch of the sensor.
- What happens: The camera will beep, and it will instantly create a Manual Event file.
- The File Window: It saves a clip starting 5 to 6 seconds before you waved your hand, plus the next 50+ seconds, ensuring you catch the full incident.
Note: By default, this sensor is sometimes set to turn audio recording on/off. You can change it to trigger manual recordings instead by opening the BlackVue App → Camera Settings → Firmware Settings → System → Proximity Sensor → Set to Manual Recording.
2. What Happens to the File (SD Card & Cloud)
- On the SD Card: The video clip is marked with an "M" (Manual) tag and moved into a protected directory on your 16GB memory card. The camera's regular loop cycle will not overwrite this file.
- Sending to the Cloud: If your camera is actively connected to an in-car mobile hotspot, it can upload these files automatically.
- Open the BlackVue App.
- Go to Firmware Settings → Cloud Settings → Event Auto-Upload.
- Ensure Manual Recording is checked. The camera will instantly back up the manual clip to your secure BlackVue Cloud storage space.
Would you like help navigating the firmware settings menu to change that sensor function, or do you need to know how the free Cloud storage limits handle auto-uploaded files?
what is the cost to purchase today ?
The BlackVue DR750S-2CH is an older, legacy model that has been officially discontinued by the manufacturer, meaning it can no longer be bought directly from authorized dealers like The Dashcam Store. [1]
However, you can still find leftover new inventory or third-party listings online:
Current Market Pricing
- New-In-Box Retail Stock: A few online audio and specialty outlets, such as Sonic Electronix, still carry remaining new factory stock of the camera bundle for $379.99. [1]
- Hardwire Bundles: Extended kits that package the camera together with upgraded storage and a battery-saving hardwire kit sell on Walmart for $569.00. [1]
- Secondary Market: If you are comfortable looking at open-box or lightly used options, individual sellers regularly list the DR750S-2CH on platforms like eBay with prices fluctuating between $450.00 and $480.00 depending on the size of the included SD card. [1, 2]
Should you buy this model today?
If you already own this unit, it remains an excellent camera. However, if you are looking to purchase a brand-new system today, it is highly recommended to look into BlackVue's newer generation models like the DR750X Plus or DR970X. They cost roughly the same price brand-new but offer vastly improved video compression, built-in voltage meters (eliminating the need for external hardwire boxes), and seamless Bluetooth pairing.
Are you shopping around for a new dashcam setup, or are you trying to price out a unit you already own or intend to sell?
