4K Backup Camera 4CH Dash Cam with 10.36in Quad Split Touch Screen - 4

In this review the ASLONG 4K Backup Camera 4CH dash cam stands out as a wired, vehicle-grade camera system aimed at drivers who need comprehensive exterior coverage. The single biggest reason to buy is the quad-split 10.36in touchscreen with built-in DVR, which records continuously and gives real-time views from four waterproof cameras for a true 360-degree awareness. It is best suited for larger vehicles where blind spots are a real safety concern and where hardwired, ignition-activated recording is preferred.

Key Features

• Quad split 10.36in touchscreen: Shows four camera feeds at once so drivers can monitor front, rear and both sides without switching screens.
• Built-in DVR recording: Default boot recording and loop recording preserve footage on a local TF card up to 128GB for incident review.
• Wired camera reliability: The hardwired design avoids wireless dropouts and uses one power cord to feed the whole system for stable connections.
• Wide angle and night vision: 170 degree lenses and enhanced low-light imaging improve visibility around the vehicle in dark conditions.
• Vehicle power and safety: Designed for 9-36V systems and requires a fuse box circuit of at least 20A for safe, ignition-activated operation and long life.
• Weatherproof cameras: Waterproof housings allow reliable outdoor use in rain or sun for trucks, RVs and trailers.

Who It's For

This system is a practical fit for drivers of RVs, semi trucks, box trucks, buses and other heavy vehicles that need multiple simultaneously visible camera angles and a robust hardwired setup. Fleet owners and solo drivers who prefer a wired installation with ignition-triggered recording will value the built-in DVR and the ability to store footage locally.

Drivers who want a simple plug-and-play wireless camera or need smartphone compatibility should look elsewhere, since installation requires wiring to a vehicle fuse box and some customers reported compatibility limits with certain phones. Also, compact car owners who do not need four external cameras may find this system more than required.
