4.Features Intorduction
VCAN1684 is a smart Linux vehicle-mounted device with full HD video recording, and a built-in AI intelligent algorithm, supporting ADAS, DMS, BSD, and 360°. It has a compact and portable design with an aluminum alloy casing, light and tight, and good heat dissipation.
VCAN1684 adopts industrialized components, with the operating temperature reaching -20°~70°, and operating humidity reaching 20%~90%, it can work normally in harsh environments. VCAN1684 uses the Linux system, which is more stable than the Android system and has twice the number of disk reads and writes than other dash cams. Real-time audio and video information and GPS data can be transmitted to the CMS platform on cell phones and PCs via 4G and built-in WIFI, and managers can track and manage assets via CMS.
VCAN1684 supports the use of 2 SD cards for recording. During the driving process, the video information in the field of view is recorded and stored in the SD card, and the video is stored in a loop; it can record images and sounds of the whole process of vehicle driving, providing effective evidence for traffic accidents and protecting your legal rights.
VCAN1684 is also a very privacy-conscious device. The device’s SD card and SIM card are locked and protected, and the video files in the SD card are encrypted. The video cannot be played back even if the SD card is removed. ES-AHD7704G-B is equipped with an in-car battery health monitor that can be used to check the status of the battery. When the voltage falls below the safety warning, the driver will receive an alarm alert and stop the car to prevent damage to the car battery.
