Trying to protect our family and this angel

Hi, my name is Mike. My partner Morgan and our children Sol and Eden, are seeking help from the community. We have both been clean for over a year, and have been thriving, recently found out our home has been entered and disturbed on several occasions, both while we were home and away from the property. Damage to front doors from outside, and windows, from inside and out, has occurred which has called for the need for some extra security. We've had personal items and three bikes stolen. Items moved around the house, windows left open from the outside, and window wood carved away inside the windows, to allow later access to our domain. I have one camera installed, but our place is large and requires at least three more cameras. We also found a fence system which would minimize the access points from the outside and increase the chances of catching whoever is responsible. Unfortunately, we do know of one person who is responsible, but without recorded documentation the police claim they can do nothing further. The second person we are afraid is involved has a record of stalking and violence towards his own family and others. Knowing these people and their history is the only reason I'm asking for help. Our family has gone to impossible tasks to be together, to have clean parents, and to give our children the safety and comfort they deserve at home. I will put updates on my page to show the security progress as it goes, and I would also be willing to borrow a security system if one is available. I've already spent my last check on a nice camera, several security lights, and new locks on multiple doors. Our home is older and does not have locking devices on several windows. I've placed wood restraints in many, and somehow the terror is continuing. We've been quite a while free of negative people and influences and just want a safe peaceful life. If you can help please do and I will do my best to pay it forward.
