I am using the dash cam (S4 True 4K 4G Front/Rear Dual Cam ADAS BSD) for the last 15 days in my Tata Nexon EV. Did the installation DIY. Mr. Rampravesh was very helpful in setting up the cam with the various functions. One minor glitch was sorted out immediately within 2 days via firmware update. Highly recommended product.
