System consists of four ultra-hermetic cameras, a special processing unit that merges the video feed from all cameras into a single panoramic image. To ensure high quality and informative video feed in any time of the day, including in complete darkness, all cameras are based on a highly sensitive HD 1/3’’ (720х480) sensor and stream video in 580 TVL resolution. Each camera records a separate video channel at D1 (704х576) resolution and 30 frames per second. The video recording process runs without interruptions due to the loop overwriting function. Video clips are stored on a micro SD memory card (up to 32 Gb) or a USB stick. After the engined is turned off, the device stop recording and shuts down. Once the impact sensor (G-sensor) is tripped, the system turns on automatically, records a 120-second video clip and then shuts down again. The system allows adjusting the G-sensor sensitivity to ensure maximum accuracy depending on the weather conditions and situation around the car. To prevent the car battery from discharging, the system controls the voltage of the on-board power system: when it reaches 11.7V, the device shuts down completely and resumes operation only when the ACC signal is transmitted again.
