I had to do what I was there to do.Of course you would and if they didnt answer the door after you knocked ?
95% of property owners who did question my presence( rare) would understand once I explained my presence and showed my ID badge.
The other 5%, were for the most part being jerks. I would leave or cross the adjacent property to get to the pedestal.
One guy got real pissed off at me for doing just that. He threatened to call the police. I told him to go on and do that.
By the time they got there I was loading up to leave. The PO asked me for my ID. SHowed it to him and he told me to leave. Man that other guy was all kinds of pissed off. Ef him.
