Can I make a complaint at a Gardai Station instead of calling the police to my house?

Basically, scumbag neighbours down the road have been dumping rubbish in the vacant house garden across from me. It's filthy now around here because of these people. They don't care about discretion and do it in broad daylight and at night. I want to call the gardai whenever I see it happening, but my family tell me not to because the gardai will come to our house and then the dumpers will know it was us who called the authorities. They also say I'm overreacting and will just draw negative attention to our house.

Anyway, I'm a grown woman and should be allowed to report criminals to the police without being called a drama queen. I don't want my family to know, so anyway, if I go to the gardai station and report it there with pictures and cctv as proof of all the incidents of dumping, the gardai won't have any reason to come to my house and talk if I call again if I see the neighbours dumping again?
