I picked up a on time feeder and set it up last week.
How long do you figure it will take the heard to get used to the noise?
I use to get between 100 and 200 pics a week,but am now at a week with maybe 5 pics .And thier not even feeding,just checking things out.

Sounds to me like your neighbors have started corn feeding before you have and now the deer are patterning their feeders over yours. Noise isn't an issue. Do you have the camera set up for 24 hours use? Sometimes it's too hot to get deer moving this time of year if you take pics only in the daytime.

Naaa ,week before feeder went out ,had 200+ pics in 7 days.
One guy hunts but dosent feed until a week befor shotgun
Camera is set for 24 hr
dumpped 50# of corn around feeder also,That usually last 2-3 days this time of year.
Guess I'll just have to wait and see.
I'v gotten about 10 pics of a fawn and 5 of the doe.

When we've placed feeders it usually took about a week to ten days for it to start getting hit.

The noise won't bother them. In the beginning they'll check it out because they're curious, once the realize there's food, it's like a dinner bell!

Dinner Bell is right on. Many times when I get to the stand in the afternoon I'll trip the feeder early and hussle back to the stand. Often the deer are there before I can get back into the stand. I had an Axis charge up on the feeder when first filling it in September one year--hungry deer.

did the same with my feeder and Texxan is correct it took about two weeks and my feeder was getting hit like crazy. JUST WAIT.
