• Recording: Recording starts automatically upon power-up. Video files are typically saved in AVI format.
• File Segmentation: Videos are automatically split into files of 5 to 30 minutes in duration to prevent data loss in case of unexpected power loss.
• Accessing Footage: To access recorded footage, power down the DVR, remove the Micro SD card, and insert it into a computer's card reader.
• Built-in Microphone: The integrated microphone records audio along with video.

7. Maintenance
