Can the property reminder notice be used as reminder evidence if it is not photographed on the door?

I can't. Posting a reminder notice stipulates that if the owner is unwilling to sign, he can prepare a recording pen in advance to record the contents of the reminder conversation, or post the reminder notice at the owner's door and record it with a video camera or video camera (pay attention to displaying signs or iconic features). This reminder notice can be used as valid evidence in law, and it can't be used as reminder evidence without taking pictures.
