HD 720P Rear-view Backup Parking Assist Camera puts out 720P HD video signals. The special wiring design and system firmware allow users to have a live rearview even when the vehicle is moving forward, avoiding obstructions caused by passengers, headrests and the vehicle’s roof & rear pillars, expanding the field of view, offering the driver an unimpeded view of the lanes behind and eliminating traditional blind spots. It only works with ATOTO S8 Gen2 and Gen1 (firmware update required) car stereo models. The 720P video image quality is much higher than on traditional cameras that put out CVBS signals. This camera is not compatible with car stereos of other brands! This camera has a 180° wide viewing angle and is specified for working with selected ATOTO S8 Android head units that come with VSV (Virtual Surround View) parking feature. An extra calibration cloth is included in the package, and the retailing price covers both the camera and the calibration cloth. Easy installation. 2 mounting options: you could choose mounting either with or without the bracket included. A 8-meter-long extension wire is included in the package. It does not work with ATOTO S8 MS,S8 UN,S8 PN, A5, A6, F7, X10 models, P5,P8,P9 series or car stereos of other brands.
