Firmware archive for the Dahua DH-XVR1A04 digital video recorder, with the name indicating a 16MB flash chip. Repairers write a dump like this directly to the recorder's SPI flash with a programmer when the unit is stuck in a boot loop or fails to start after a bad update. The 29.6 MB archive probably holds more than one file, so check the contents. Read and back up the original chip before writing, and confirm the chosen image is exactly 16MB.
