A:Answer It records in approximately 3 minute segments. When you watch the video files, there is no gap between the end of one file and the next. If you use the 2nd (rear) camera, two files will record at the same time on the micro SDHC card. I use a 64GB card which records 10-12 hours before overwriting older files. If you only use the front camera, you can record more time. It would be a good idea to get more than one card so you still have one in the camera when you copy the files to your computer for viewing. Video files are created in .mov format and are high quality color for the front camera, lower quality black and white for the rear camera. There is an option to change the quality of the recording which will affect the storage space required for each file. Files are identified by date and time of recording and an A for the front camera or a B for the rear. The view screen on this camera is to small to see the playback well. I would recommend this camera to anyone.
