説明
Accidents rarely happen in front of you. They happen all around you. The Dual Witness answers with two lenses working as one system, a front camera capturing 1440P detail of the road ahead and a rear camera covering 1080P of everything behind, so the story your insurer hears matches the story the road actually told.
This is the upgraded successor to the widely reviewed A400, refined for sharper optics, smarter parking protection, and longer recording endurance. The front sensor reads license plates in daylight and retains usable detail after dark, while the rear unit brings the same reliability to the lane changes, tailgaters, and parking-lot surprises that front-only cameras never see. With support for cards up to 256GB, the system records for days without demanding attention.
Both lenses feed into one clean interface, one app, and one timeline, so reviewing an incident takes seconds instead of a card-swapping scavenger hunt. The 24-hour parking mode keeps the system alert while the engine sleeps. Whether you commute through city traffic or drive for work, the Dual Witness makes sure that when something happens, you are never the only one who saw it.
One lens sees the road ahead. Two lenses see the truth.

Application Scenarios
The Dual Witness is built for the daily commuter navigating crowded highways, the delivery driver whose vehicle spends all day in motion, the rideshare operator whose passengers change every hour, and the family car that carries the people you care about most. Front and rear coverage also makes it the right choice for fleets and small business vehicles, where a single incident can otherwise turn into a dispute with no evidence.
Frequently Asked Questions
Q: Why do I need a rear camera?
Front-only cameras miss the lane changes, rear-end approaches, and parking-lot incidents that happen behind you. A rear camera captures the full context of an incident, which is frequently the difference between a settled claim and a contested one.
Q: How does the 24-hour parking mode work?
When the engine is off, the system switches to a low-power monitoring state and wakes on impact or motion. For multi-day parking protection, pair it with the recommended hardwire kit or auxiliary battery pack.
Q: Will the system support a 256GB card?
Yes, the Dual Witness is designed to work with high-endurance microSD cards up to 256GB, which extends recording time to multiple days before the loop overwrites the oldest footage.
Q: Is installation complicated?
No. The front camera mounts to the windshield, the rear camera mounts to the rear glass, and both cables route discreetly along the headliner. The companion app guides the setup and lets you verify both feeds before you drive.
Q: Can I review footage easily after an incident?
Yes. Both cameras share one timeline in the app, and G-sensor events are locked and highlighted so you can jump straight to the moment that matters instead of scrubbing through hours of video.
