If you want to delete security camera footage, there are a few things you need to know. First, make sure that the footage is actually stored on the camera itself. Many cameras store footage on a removable media, like a USB drive or SD card. If the footage is stored on the camera itself, you can delete it using the camera’s own software. If the footage is not stored on the camera itself, you will need to find a way to remove it from your storage system. This could be done by deleting it from your computer or by burning it to a disc and destroying it. Whatever method you use, be sure to backup any important data before deleting security camera footage ..
