A:Answer Hi, please note that we do not recommend using any USB Drives/ Memory Cards other than the SanDisk® High Endurance/ MAX Endurance Memory Cards to be used with devices like Dashcams, Video Monitoring, Security/ Surveillance Devices, and In-Car Recording Devices as these devices perform constant read and write operations while recording continuous videos. Please use a SanDisk® High Endurance/ MAX Endurance Memory Card with a USB Memory Card Reader in your DVR's USB port since these Memory Cards are specifically designed for constant Read/ Write Operations. You can purchase the SanDisk® High Endurance Memory Cards for the above applications from our official online store or from Best Buy.
