What is the maximum storage capacity on the camera/DVR?

Local storage capacity depends on the size of the SD/hard drive and number of attached cameras. For example:

• A forward-facing camera with 128GB SD can store approximately 47 hours of main-stream driving footage (assuming standard configuration of 1080P / 15 frames per second)
• A forward-facing camera (with either a driver-facing or rear camera, for example) and 128GB SD can store approximately 26 hours of main-stream driving footage (assuming standard configuration of 1080P / 15 FPS for main channel and 720P / 15 FPS for secondary channel)
• A VT5500 DVR (with 1 TB hard drive and 5 connected cameras) can store approximately 84 hours of main-stream driving footage and 135 hours of sub-stream driving footage (assuming standard configuration of 720P / 15 FPS for main-stream and D1 / 15 FPS for sub-stream)
• A VT6.3 DVR (with 4 TB hard drive and 8 connected cameras) can store approximately 200 hours of main-stream driving footage and 560 hours of sub-stream driving footage (assuming standard configuration of 720P / 15 FPS for main-stream and CIF+D1 / 15 FPS for sub-stream).
