Clearing CCTV camera video involves deleting recorded footage to free up storage space or to ensure that the data is no longer accessible. This process can vary depending on the type of recording system you are using, such as a Digital Video Recorder (DVR) or Network Video Recorder (NVR). Here’s a step-by-step guide to help you clear CCTV camera video effectively and securely.
Tools and Materials Needed:
- CCTV camera system (DVR or NVR)

Step-by-Step Process:
- Access the DVR/NVR:
- Log In: Use your admin credentials to log into your DVR or NVR system through its web interface or dedicated software.

- Select the Video Footage:
- Choose Date and Time: Use the calendar and time sliders to locate the specific footage you want to delete. You can usually select a range of dates and times.
- Review Footage: If needed, review the footage to ensure you are deleting the correct videos.
- Delete the Footage:
- Select Delete Option: Look for the delete or erase option in the storage management section. This option may be labeled as “Delete,” “Erase,” “Clear,” or something similar.
- Confirm Deletion: The system will typically ask for confirmation before deleting the footage. Confirm that you want to delete the selected videos.
- Clear All Footage (Optional):
- Select All Footage: If you want to clear all recorded footage, look for an option to select all files or a “Clear All” button.

Additional Tips:
