TL;DR Daytime plate legibility unconfirmed, no independent community footage comparison found at time of review; Rexing specs all three channels (front, cabin, sides) at 1080p with an F1.6 lens. Night vision: independent footage comparison not available at time of review (the cabin channel uses IR LEDs, but no community footage confirms the result). Parking mode is an auto-event / time-lapse parking monitor with no buffered pre-record, and the Smart Hardwire Kit is sold separately. Supercapacitor design (no lithium battery), rated -20°F to 176°F. FCC assumed; no UL/ETL electrical safety certification confirmed.
The S3 is a 3-channel rideshare dash cam recording the road ahead, the cabin, and the vehicle sides/doors, all at 1080p through an F1.6 seven-element glass lens at a 170° angle. The side coverage is what sets it apart from front-plus-cabin cams. No independent community footage comparison confirming daytime plate legibility or the IR cabin/night result was available at time of review, so those are manufacturer claims, not corroborated results. The parking monitor uses auto event detection and time-lapse with no documented buffered pre-event recording, and the Smart Hardwire Kit it needs to run engine-off is sold separately, as is the microSD card. The supercapacitor design carries no lithium battery and is rated -20°F to 176°F, removing the hot-car battery-degradation failure mode. Wi-Fi is 2.4GHz, the slower band, so wireless clip transfer lags the flagship; the Rexing Connect app has documented connection complaints across the line. The screen is a 3-inch non-touch LCD.
Best match for rideshare and taxi drivers who specifically need three angles, road, cabin, and sides, in one budget unit, and who value the supercapacitor for hot-windshield duty. Skip it if you want best-in-class footage or do not need side coverage: the front channel is only 1080p, and the hardwire kit and card cost extra. Drivers who only need front-plus-cabin can save with the Rexing V3; drivers wanting sharp front-plus-rear road footage should look at the higher-resolution Rexing R88.
No PPE is required for installation or normal use. The supercapacitor design contains no lithium battery, removing the thermal-runaway disposal concern. The device qualifies for standard e-waste drop-off (Best Buy, Call2Recycle); no manufacturer take-back program is documented. No independent UL or ETL electrical safety certification was located for the S3; FCC radio-emissions compliance is assumed for a US-market wireless device. No California Prop 65 warning is documented on the manufacturer listing.
The S3 is a 3-channel rideshare cam: it records the road ahead, the cabin interior, and the vehicle sides/doors at the same time. The side coverage is the differentiator. It is aimed at rideshare and taxi drivers who need to document curbside passenger interactions and side or door events that a front-only or front-plus-cabin cam cannot see.
The V3 is a 2-channel cam that records the road ahead and the cabin only. The S3 adds a third channel for side/door coverage, so it captures three angles instead of two. Both are supercapacitor cams aimed at drivers who carry passengers, but only the S3 sees the sides of the vehicle.
No. The Smart Hardwire Kit and the microSD card are both sold separately on the S3. The card supports up to 256GB high-endurance microSD, and the parking monitor needs either continuous car-charger power or the optional hardwire kit to run while the engine is off. Budget for both add-ons when comparing the real cost.
No lithium battery. The S3 uses a supercapacitor, which Rexing describes as a built-in emergency file backup that lets the camera operate from -20°F to 176°F. That removes the battery-degradation and thermal-runaway risk that affects lithium dash cams parked in hot cars, though it means the cam must stay powered from the vehicle.
All three channels record at 1080p (front, cabin, and sides). There is no higher-resolution front channel, so it sits below cameras like Rexing's R88 (4K front) or the V33 (1440p) on raw resolution. No independent community footage comparison confirming the S3's real-world plate legibility was available at time of review, so the footage signal is based on the specification, not corroborated footage.
