First of all, you cannot prevent break-ins. You can only make it very difficult and very time consuming, two things the common burglar hate.
To make it difficult for them, install correct locks on all doors that give acess. Use locks that do not have a single point of failure, like 3-locks. If the lock is stronger than the door, they will kick in the door.
To make sure they are visible, install lights that respond to human movement and place them on difficult reachable places so people cannot disable them quickly. Make sure to cover every possible entry of your house. Doesn't need to be a big light, but make people visible.
Write down serial numbers of important possessions and store those in a protected environment on the internet.
Use a UV-marker to invisible mark your posessions. If you find them again, you just hold them against a UV light to prove they are yours.
Encrypt all your drives with the lowest encryption so that your data cannot be retrieved.
You could also install a webcam with ip connection to the internet. You can set it up to make pictures when it detects movement. Burglars may destroy your webcam quickly, but you have at least one picture of them. Make sure to protect it a little by puting it behind a glass or something and be as creative as a burglar when installing them (can you destroy or make then unusable with how much time).
And lastly but most importantly: Try to have people watch your house on a regular basis when you're gone.
