Revolutionizing road documentation with unparalleled clarity, our industry-first dual-channel system captures crystal-clear 5K front footage paired with 2K rear recording – delivering 300% more detail than standard 4K models.

Engineered from bespoke tooling, this model features a distinctive unibody construction that eliminates generic designs, offering both aerodynamic aesthetics and enhanced durability."

Sigmastar Industrial-Grade 5K Chipset

Powered by SigmaStar's automotive-grade processor, specifically engineered for 5K video processing with military-grade temperature tolerance (-30°C to 85°C) and 30% faster encoding than consumer chips

Dual Sony Starvis Sensors (Front/Rear)

Equipped with dual Gen2 Sony STARVIS™ CMOS sensors featuring 2.4μm ultra-large pixels for exceptional low-light performance, capturing license plates and road signs with 95% accuracy at night.

Rear Camera with Hardware HDR + Starlight Night Vision

Proprietary hardware-level HDR on the rear channel combines with f/1.6 aperture for extreme light capture, maintaining color accuracy in challenging backlight conditions (up to 120DB dynamic range)

5Ghz Dual-Band WiFi for Instant Sharing

Enterprise-grade wireless connectivity enables 3x faster video transfers (up to 867Mbps) compared to 2.4Ghz systems – download a 5-minute 5K clip in just 12 seconds via our dedicated mobile app

Dual-Mode GPS (Built-in + Optional External)

Precision dual-GPS system combines built-in positioning with optional external antenna support, recording coordinates with ±3m accuracy and overlaying 15 critical data points (speed, altitude, G-force) on footage

Advanced Thermal Management System

Patented copper heatsink + graphene cooling layers maintain optimal performance in extreme environments (tested for continuous operation at 85°C), with 50% better heat dissipation than conventional models

Supercapacitor + Backup Battery System

Military-spec supercapacitor ensures reliable parking mode operation (-40°C to 105°C), while the CR2032 backup battery preserves settings for up to 10 years without main power
