【4K Ultra HD High-Definition & 4K Drive Recorder Different from the Market】The JOMISE 4K drive recorder achieves high-definition with IMX415 4K UHD (3840×2160P) and 8 million pixels. Unlike other 4K drive recorders on the market, the JOMISE does not reduce the front shot image quality to 2K or lower when simultaneous front and rear recording is selected. Because JOMISE uses a flagship chip, the operating speed is 1.65 times faster than normal, the screen is smoother, the image quality is clearer, and it is easy to operate smartly at high speed while moving the front and rear lenses. Equipped with two front and rear cameras, simultaneous front and rear recording is possible. With front UHD + rear full HD, it reliably records high-definition and smooth video of accidents, reckless driving, and troubles. 【Easy Installation & Can Be Done in 15 Minutes Even by Women】The ultra-precise mold used to record front and rear with the JOMISE drive recorder has a streamlined arc shape, making it smaller and more beautiful. It is less likely to deform under high and low temperature conditions, and the power supply is stable. Unlike ordinary mirror types, which tend to have a screen size that is too large and cannot completely block the influence of the original car's rearview mirror, the JOMISE compact smart recorder maintains the original appearance of the original car and does not obstruct the view as much as possible. Even women can install it completely in 15 minutes, making it the best product to recommend to family and friends. 【Continuous Overwrite Recording + Emergency Recording + 24-Hour Parking Surveillance】➊ When the engine is turned ON (power on), the drive recorder automatically starts loop recording, and when the engine is turned OFF (power off), it automatically saves the recording. ➋ Continuous recording (loop recording): The recording files are divided into fixed lengths of a few minutes each, and when the memory card capacity is insufficient, the recording continues by overwriting from the first file. ❸ Emergency recording: If an impact is detected during continuous overwrite recording, the file is locked and saved without being overwritten. ➍ 24-hour time-lapse parking surveillance records a short video of 1 second / 1 frame "1fp", so you won't miss important moments, and even when the drive recorder engine is stopped, it is fully supported 24 hours a day!
