VIOFO Front + Dual Waterproof Side Cameras

Purpose-built for large trucks, construction vehicles, and commercial fleets. The VIOFO A329WW pairs a 4K front camera with two IP67 waterproof exterior cameras designed to mount on the left and right sides of the vehicle — eliminating the dangerous blind spots that cause the majority of side-swipe collisions, turning accidents, and worksite incidents involving large vehicles.

Side-Mount Coverage for Trucks and Heavy Equipment

Standard dash cams only cover what's directly ahead and behind. For semi-trucks, dump trucks, concrete mixers, excavators, box trucks, and construction vehicles, the most dangerous blind spots are on the sides — where pedestrians, cyclists, and smaller vehicles are invisible to the driver during turns and lane changes. VIOFO's dual waterproof cameras mount on the left and right exterior of the vehicle body, capturing both sides simultaneously in 2K with HDR. With cable lengths up to 15 meters, the cameras reach any mounting position on even the largest rigs and trailers.

Real-World Use Cases

  • Highway lane changes — Record vehicles in adjacent lanes during merging, eliminating disputed fault in side-swipe incidents.
  • Right-turn blind spots — Capture cyclists and pedestrians on the curb side during turns, the most common cause of fatal truck accidents.
  • Construction sites — Document vehicle surroundings while operating in tight, high-risk work zones with workers on foot.
  • Loading docks and backing — Record both sides during reversing maneuvers at warehouses and distribution centers.

Built on the A329 Flagship Platform

The A329WW runs on the A329S flagship platform — 4K 60fps front recording, Wi-Fi 6, USB 3.0, and external SSD storage up to 4TB for over three weeks of continuous 3-channel recording. Both waterproof cameras use Sony STARVIS 2 sensors with HDR. The supercapacitor handles the extreme temperature swings, vibration, and dust exposure of construction and commercial vehicle environments from -20°C to 65°C.

Front & Two Waterproof Rear Dashcam FAQs

Where should I mount the two waterproof cameras on a truck?
The most common configuration is one camera on each side of the vehicle — left and right — covering blind spots during lane changes and turns. This is the recommended setup for semi-trucks, box trucks, and construction vehicles. Alternatively, mount both on the rear corners for backing and loading dock coverage, or one at the rear and one on a side. Cable lengths up to 15 meters support any mounting position.
What types of vehicles benefit from dual side cameras?
Semi-trucks, dump trucks, concrete mixers, excavators, box trucks, delivery vans, RVs, buses, and any large vehicle with significant side blind spots. The system is especially valuable for construction vehicles operating in tight work zones where pedestrians and workers are frequently near the vehicle's sides.
Can the waterproof cameras withstand construction site conditions?
Yes. Both cameras are IP67 rated — completely dust-tight and waterproof against temporary submersion. Combined with the supercapacitor's -20°C to 65°C operating range, the system handles rain, mud, road dust, vibration, and the extreme temperature swings typical of construction and industrial environments.
How much continuous recording can this system store?
The A329WW supports microSD cards up to 512GB plus external SSD storage up to 4TB via USB 3.0. With 4TB of SSD storage, the system records over three weeks of continuous 3-channel footage before loop recording overwrites — ideal for long-haul trucking and fleet operators who need extended evidence retention.
