I have an older security camera system with four real cameras in the front of the house and three fake ones. A solar lit security sign with a security system name on it although not the same security system I am currently using. A large solar security light that comes on when there is movement in the front yard. People cannot get into my back yard without going through my front yard, but I have rocks and things to throw at them if they do. I used to have the best dog in the world, and he would bark and alert me if anyone was near the house, but he has gone to doggie heaven. I make up for it now and at times will bark like he did when someone comes around that I don't like. Also, the key fobs for my cars are nice because I can set the car alarms off when suspicious people are around to warn my neighbors. In the past I have left the dashcam in my car on and faced it towards the front of the house so it can record what is going on, but it is a drain on the car battery, and you need to run the car every day or two to keep the battery charged up.
