5. Key Features

5.1. Dual 4K Recording & STARVIS 2 Night Vision

The A80 Pro captures video in stunning 3840×2160P dual 4K resolution for both front and rear cameras.

5.2. Ethernet Rear Camera Processing

Unlike traditional AHD systems, the A80 Pro utilizes an Ethernet-based system for its rear camera. A dedicated processor in the rear camera handles footage independently, allowing the main processor to focus on front camera imaging. This results in superior 4K image performance for both cameras and improved system responsiveness.

The built-in G-Sensor detects impacts instantly, automatically locking the video to protect evidence whether your vehicle is driving or parked. Time-lapse recording is also available to compress hours into minutes, saving storage space while maintaining continuous surveillance.
