The Pioneer VREC-DH300D is a 2-channel dual recording dash camera system that mounts a Wide Quad HD (WQHD) 1440p dash camera directly to your vehicle’s front windscreen and a Full HD 1080p compact second camera to your vehicle’s rear window, capturing video of both the road ahead and behind. The main unit records a diagonal wide viewing angle of 135° with WQHD technology for enhanced imagery under low light or night conditions. The rear camera is compact and features a diagonal wide viewing angle of 128° with Full HD technology to achieve higher camera visual recognition performance in both light and dark conditions. Both front and rear cameras feature a STARVIS™ back-illuminated CMOS sensor that constantly adjusts the image quality producing bright, richly colored videos and identification-level recordings that capture critical details such as license plates, road signs, and traffic signals. Additional features include a 3" LCD display on the front camera/main unit for easy operation and built-in GPS for speed/location/heading/time data acquisition, If an incident occurs while driving, the built-in 3-axis G-Force motion sensor will detect the vibration and automatically capture and save video 20 seconds before and after an incident is detected.
