DDPAI Z90 Master 4K Dual-Channel Dash Cam

Complete Road Monitoring with the DDPAI Z90 Master

The DDPAI Z90 Master is a high-performance dash camera system designed to provide comprehensive visual evidence and security for vehicle owners. By utilizing dual 4K recording capabilities, this device captures high-definition footage from both the front and rear of the vehicle simultaneously. This level of detail is essential for insurance claims, resolving road disputes, and monitoring driver behavior with precision.

Equipped with industry-leading Sony STARVIS 2 sensors, the Z90 Master addresses the common problem of poor image quality during nighttime driving or in high-contrast environments. Whether you are navigating busy city streets or parking in dimly lit areas, this system ensures that license plates and critical road details remain visible. The addition of an optional 3K cabin camera allows for a full 3-channel setup, making it an ideal choice for rideshare drivers and fleet managers who require internal monitoring.

Advanced Imaging Technology

The Z90 Master features dual Sony STARVIS 2 IMX678 8MP sensors for both the front and rear cameras. This setup is paired with NightVIS 2.0 and an AI ISP (Image Signal Processor) to optimize footage in low-light conditions. The Triple HDR technology balances exposure across varying light levels, preventing blown-out highlights from headlights or loss of detail in deep shadows. The front camera offers a wide F1.75 aperture, while the rear uses an F1.7 aperture to maximize light intake.

Functional Design and Build

Designed for reliability, the Z90 Master uses a supercapacitor rather than a traditional lithium battery. This allows the device to operate safely in extreme temperatures ranging from -20°C to 70°C without the risk of battery swelling or failure. The 3-inch screen provides an immediate interface for viewing footage and adjusting settings, while the built-in GPS accurately logs speed, time, and driving routes for a complete record of every journey.

Technical Specifications

Storage Reliability and Connectivity

To ensure footage is never lost, the Z90 Master utilizes D²save 2.0 technology. This dual-storage system automatically switches to the built-in 64GB eMMC storage if the external microSD card encounters an error or fails. For data transfer, the 5GHz Wi-Fi provides high-speed downloads to the DDPAI mobile app, where users can manage settings and export videos. The system is also compatible with a 4G module for remote monitoring, depending on the chosen configuration and local service availability.

Parking Monitoring and ADAS

When combined with a compatible hardwire kit, the Z90 Master supports 24-hour parking surveillance. It offers time-lapse recording and impact-triggered recording to protect the vehicle while unattended. Additionally, the ADAS 2.0 (Advanced Driver Assistance Systems) provides safety alerts, including driver fatigue warnings and forward-vehicle-start alerts, to help maintain awareness on the road.

Usage and Installation

The main unit is mounted to the windshield using the included electrostatic sticker and 3M adhesive to prevent residue. The rear camera is typically mounted on the rear window and connected to the main unit via the provided cable. For full parking mode functionality, professional installation of a hardwire kit to the vehicle's fuse box is recommended. The included CPL filter should be attached to the front lens to reduce dashboard reflections and glare from the sun.

Frequently Asked Questions

What is the benefit of the built-in 64GB eMMC storage?
The eMMC storage is more stable than traditional SD cards. It acts as a backup (D²save 2.0) if your microSD card fails, ensuring that critical emergency footage is recorded directly to the internal memory.

Does this dash cam record inside the car?
The standard 2-channel setup records front and rear. If you require interior monitoring, you must select the 3-channel package or purchase the compatible cabin camera separately.

Is a hardwire kit necessary?
A hardwire kit is only necessary if you wish to use the 24-hour parking monitoring feature. For standard recording while driving, the included car charger is sufficient.

How does the CPL filter improve video quality?
The Circular Polarizer (CPL) filter reduces reflections from the windshield and dashboard. This results in clearer footage with better color saturation, especially in bright, sunny conditions.

What speed of microSD card is required?
Because of the high data rate of 4K recording, a U3 or UHS-3 rated microSD card is required. Using slower cards may result in recording errors or system instability.
