EyeOnRoads R4 — 4K Dual Dash Cam for Everyday Protection
When the other driver's story doesn't match yours, footage decides. The EyeOnRoads R4 records the road ahead in true 4K UHD and covers your rear in Full HD 1080P — both cameras rolling at once, with a Sony IMX335 sensor and F1.6 aperture built for low light. A 170° wide angle keeps neighboring lanes and side-swipes in frame, so nothing important happens outside your evidence.
Front 4K UHD + Rear 1080P Dual
The front camera records true 4K (3840×2160) at 30fps for razor-sharp plate readability, while the rear camera covers 1080P Full HD — both channels rolling simultaneously so a rear-end hit is on record as clearly as a front-end incident.
Sony IMX335 + F1.6 Night Vision
The Sony IMX335 sensor paired with an F1.6 large aperture pulls in more light than standard dash cams — so tunnels, unlit streets, and parking garages stay clear enough to read a license plate, not just guess at one.
170° Ultra-Wide Coverage
A 170° lens captures neighboring lanes on both sides, not just what's straight ahead — so lane-change collisions, side-swipes, and cut-offs are inside the frame instead of just outside it.
Built-in WiFi & Mobile App Access
Pair the R4 with your phone over WiFi to preview, download, and share footage on the spot — no pulling the SD card, no laptop needed. Send an incident clip to your insurance company right from the driver's seat.
24/7 Parking Monitor & G-Sensor
Motion detection and collision alerts keep the R4 watching while you're parked — so a shopping-cart ding, a door bump, or a hit-and-run in the lot is documented instead of a mystery. The G-sensor auto-locks impact footage so loop recording can't overwrite it. Parking mode requires hardwire kit (sold separately).
Loop Recording & File Lock
Loop recording keeps rolling without ever filling the card — the R4 automatically overwrites the oldest clips. Anything the G-sensor flags gets locked into a protected folder so it survives even weeks of driving.
3.5" IPS Screen & Wide Temp Range
A 3.5" IPS display lets you frame the shot and review clips on the spot. Operating from -20°C to +65°C (-4°F to 149°F), the R4 keeps working through Texas summer heat and northern winter cold alike.
