| MR688B-V4-PV-RS232 Flagship Dual-Mode | Full-Function Video & Telemetry — Integrates with both MDVR and GPS tracking systems simultaneously. Provides 1-channel video output to MDVR, RS232 serial telemetry & photo capture to fleet platform, and I/O alarms. | DMS Alerts + 1-Ch Video Out + RS232 Data/Photos + I/O |
Compatible Peripherals & Accessories
| Hand Setting Instrument | Field calibration and parameter programmer. Allows fleet engineers to configure alarm sensitivity, alarm startup speed, volume, overspeed thresholds, test alarm indicators, simulate indoor vehicle speed, and upgrade firmware. |
|---|---|
| Vibration Warning Cushion | Driver seat tactile warning cushion. Vibrates synchronously when the MR688B triggers a fatigue alarm, providing an immediate physical wake-up reminder for drowsy drivers. |
| CareDrive Metal Bracket | Heavy-duty reinforced metal mounting bracket (6.5 × 12.5 cm) engineered for rugged commercial vehicle dashboards, mining trucks, and heavy-duty fleet installations. |
| Dustproof Lens Protector | Protective optical shield designed to prevent airborne dust and grime from accumulating on the infrared sensor and optical lens in mining, construction, and harsh fleet environments. |
| USB-to-RS232 Debug Adapter | Engineering diagnostic cable for connecting RS232-enabled MR688B units directly to a computer for protocol verification, telemetry data validation, and factory testing. |
What MR688B Delivers
Key safety and fleet integration capabilities verified against factory engineering specifications.
Patented Infrared Pupil Tracking & Driver State Detection
Non-Contact Optical Algorithm
- All-light pupil recognition: Integrated infrared LED array ensures accurate pupil and facial feature tracking in total darkness, direct sunlight, and through standard glasses or sunglasses.
- Real-time fatigue detection: Continuous monitoring detects micro-sleep, abnormal blink rates, prolonged eye closure, and head nodding to warn drivers before critical incidents.
- Distraction & absence alerts: Promptly identifies when the driver looks away from the road, looks down at smartphones, or is not in the normal driving position.
Multi-Stage Alerts & Driver Intervention Reminders
Audible Warning & Tactile Wake-Up
- Clear in-cab voice warnings: High-volume audible buzzer and spoken alerts provide instant reminders to refocus driver attention (English standard; customizable languages supported).
- Optional vibration cushion: Synchronizes with fatigue alarm triggers to deliver physical seat vibration, effectively waking drowsy commercial drivers on long-haul routes.
- Configurable speed thresholds: Alarm activation speed and overspeed alerts can be tailored via DIP switches or hand programmer to eliminate nuisance warnings during parking or idling.
Fleet Telematics & Video System Integration
Standalone, I/O Level, RS232 & Video Output
- Versatile telematics interfaces: Choose standalone operation (SV), 5-pin I/O level signaling (PV) for GPS trackers, or RS232 serial telemetry and event snapshot transmission (RS232).
- Mobile DVR video stream: Dedicated video models (V4-PV / V4-PV-RS232) provide 4-pin aviation CVBS video output for direct recording on MDVRs and real-time remote CMS monitoring.
- Industrial vehicle design: Compact 91.5×42.5×127.5mm housing, 12V/24V wide voltage compatibility, rugged metal bracket option, and -10°C to +50°C operating range.
