BlackVue DR750S-2CH Review
Our 2017 findings, with practical recording and parking advice for the original model
Why the DR750S mattered in 2017
Our original review compared the DR750S-2CH with the DR650S-2CH, Thinkware F800 and BlackSys CH-200. BlackVue had developed Wi-Fi and Cloud features across its earlier two-channel cameras, but customers who mainly wanted clear recordings and useful parking coverage had other priorities. The Thinkware F770 and BlackSys CH-200 were alternatives we discussed at the time.
Our concerns with the DR650S included its video quality, event retention, power demands, bulky hardwiring kit and coaxial-cable durability. We wanted clearer footage and a camera that handled heat better. The DR750S retained BlackVue’s cylindrical design while changing the recording hardware. In that 2017 comparison, the hardware improvement was most noticeable at night, particularly at the rear, where the DR650S had struggled even without rear-window tint. BlackVue’s original DR750S improvements article accompanies that launch-era comparison.
This guide covers the original DR750S-2CH, not a DR750X or Plus model. The technical instructions below come from its English manual; match menus and features to your installed firmware.
60 FPS helps describe the mode, not the result
The manual lists STARVIS CMOS sensors front and rear, built-in GPS, 2.4 GHz Wi-Fi and 139° diagonal views. In Sports mode, the front camera records 1920 × 1080 at 60 FPS while the rear records 1920 × 1080 at 30 FPS. That mode uses Highest image quality and one-minute segments.
In our 2017 comparison, the higher bitrate and 60 FPS option did not give the DR750S a clear licence-plate advantage. We preferred the Thinkware F800’s low-light footage, although we found the overall differences among those three cameras fairly small.
Judge a saved clip, not the FPS label alone. Light, exposure and movement affect detail. Higher bitrate also uses more card space and shortens the amount of footage that fits before loop recording replaces it.
Night recording and storage
At Full HD and 30 FPS on both channels, the manual lists maximum front/rear bitrates of 12/10 Mbps at Highest, 10/8 Mbps at High and 8/6 Mbps at Normal. Different resolution modes have different rates. Give yourself enough space to copy an original file before making a smaller sharing copy.
Our night sample remains part of the review. A sample cannot promise the same plate detail through your vehicle’s glass or under different lighting.
Our track-day observation and the heat limits
In the hot track-day outing described in our 2017 review, the DR650S lost some focus while the DR750S did not. That specific observation helped explain our enthusiasm for the update; it does not mean every DR750S will keep recording in every hot car.
The manual specifies operation and storage from −20°C to 70°C (−4°F to 158°F). Its safety guidance recommends an optimal range of −20°C to 60°C (−4°F to 140°F), with reduced performance possible outside it. The approximately 80°C high-temperature cutoff is a protection threshold, not a recommended operating temperature. Keep the camera within its instructions rather than treating a cutoff as extra usable range.
Parking power and event files need separate checks
The manual describes Normal, Event, Parking and Manual recording. If automatic Parking mode is enabled, the camera switches to it after the vehicle is stationary for five minutes, using motion detection and impact recording. Its motion recordings and impact events include a five-second buffer before the trigger. Recording still needs power after you switch off the engine. Choose a hardwiring device or battery setup that suits this camera and your vehicle. Parked runtime depends on the power supply, its condition and the recording setup.
Event-file locking is optional and disabled by default in the manual. It retains up to 50 event and manual recordings. When that space fills, the selected overwrite policy matters: replacing old locked events removes the oldest; with replacement disabled, new events go into loop storage. Motion-triggered clips are not automatically protected by this lock setting. Driving, manual and parking events also do not become separate unlimited protected stores.
Copy a clip you need to another device promptly. Before formatting, back up everything important: formatting erases all recordings, including locked files. The manual also warns that saving changes to time, resolution, image quality or recording-segment length formats the card. Disconnect camera power before inserting or removing its microSD card.
Time-lapse was not available when we wrote our launch review; check the installed firmware before deciding which parking modes your unit offers. In our 2017 launch comparison, the DR750S lacked advanced driver safety alerts. We did not consider that absence a deciding drawback. We also discussed the different ignition-based parking transitions of competing systems. Some owners mentioned in our 2017 review preferred those ignition-based transitions. We treated that as a preference: choose the recording and power behaviour that suits your vehicle.
Local Wi-Fi is different from remote Cloud access
We liked being able to use BlackVue’s phone connection while parked in our original comparison. Nearby Wi-Fi lets your phone view recordings and change settings. Remote Cloud access needs an internet connection at the camera, a registered account and a working service connection; your phone’s nearby connection alone does not provide that once you leave.
Check current BlackVue app, service and account requirements before planning around remote viewing, notifications or backup. Explore our BlackVue dash cam range and check the Cloud features of the exact model you choose. Keep a local copy of important recordings even if you use Cloud.
Aim the cameras and check the controls
The cylindrical bodies rotate to aim their lenses. Check both live views before driving; an upside-down rear installation also has a rear-image rotation setting in the manual. Body adjustment and recorded-image rotation are different controls.
The proximity sensor can toggle audio or start Manual recording, depending on its setting. Recording-LED controls and voice-guidance options help you choose how noticeable the camera is. Check the actual menu for your firmware.
We appreciated the thin coaxial rear-camera cable for routing in our original review, but also raised durability concerns. Route it carefully without pinching or sharply bending it; do not assume a cable or mount from another generation fits. The manual lists 16, 32, 64 and 128 GB cards; check model-specific firmware guidance before buying a larger card.
Our verdict and what to check now
Our 2017 verdict favoured the DR750S for its Wi-Fi and Cloud experience while acknowledging the tradeoffs in night footage, parking transitions and file retention. Its recording and connection options still need to fit the way you use the car.
If you already own one, start with the front and rear views, a saved playback check, parking power and the event-lock policy. If you are comparing a replacement, tell us what the existing camera cannot do for you. We can help compare the setup rather than choose from a specification number alone.
