Someone tried breaking into my house!!

So I live on an 15 acher land that is gated, the picture you see is just the round of the house, and then in the back is the barn with my horses in it, its in the center of the property and the land surrounds it and then the drive way makes a cirlce around and then theirs the grass around it. So I went to throw the garbage which is outside the gate and the gate is a good 10 minute walk away from our house. So after I had thrown the garbage as I was walking back up my brother was driving out and told me he was going to the gym because ours didn't have "the stuff he needs" and he said he said he left it unlocked for me to get in, which is fine cause you cant really even get on our property (our house is the only one on there) but the door WAS locked so I had to climb through the frikin window! but when I got the thingy was ringing so that meant someone was at the gate butt hey kept ringing over and over really fast and honking so I figured it was my mom or brother in a hurry, so I looked at the camera (you cant see the gate from our house) and it was a car I didn't recognize. Well out of no where they got out of the car and tried climbing over the gate but you cant because its medal bars with pointy things at the tips. But then one of them realized there was a camera and they pointed it out and got back in the car and this part was scary but also EXTREMELY stupid! The gate is frikin medal and its thick black medal, so they decide for some RANDOM reason they want to try and get it by ramming there car into A MEDAL GATE! They did this about 3 times and there bumper fell off so they drove away, leaving there bumper on our drive way....I should of turned the sprinklers by the gate on...
