This is what I've wanted for the Sims 4 burglars:
They are in the base game, but Get To Work can increase the Sim's interactions:
•Each night, starting at 12 AM, there is a 3% chance(Very rare) of a random Sim (Townie, or premade Sim) to break into a Sim's home.
If the Sim is awake, they can fight the burglar (Higher fitness skill leads to success) Bribe them (More success if Sim pays more) or ask them to leave (Higher Charisma and a Confident sim can be better at doing this)
•Burglars have a higher chance to come to a household if a household is wealthy and had a lot of house value (A Sim with a 1 million dollar house value has a decent chance of being robbed, whereas a Sim with only 25k in house value(Mobile homes, tiny houses) have a lowest chance of robbery.
•If Get To Work is installed, and the Sim is in a Detective Career, they can arrest the burglar and they will be escorted to a rabbit hole, and if they already taken items when they are arrested, the family will be reimbursed and the objects will be taken in evidence.
Sims with higher Logic are to succeed in this option.
•An alarm can be bought and armed, so if a Sim is sleeping, or they are out of the house, they will autonomously arm the device, but the alarm must be bought next to the house's front door. Very similar to when a Sim takes off their shoes in Snowy escape, they will do it at the front door.
The alarm can be placed anywhere, and will stretch to a maximum Sim build square, before it goes off.
•If the alarm detects the burglar, the cops will automatically called, and the Sim can pick the company with ease. See below for more information,
Also a fast Sim can call the cops, and they will come, run to the burglar, and try to arrest them.
The Sim can call the cops from three different companies, randomly generated names. There will be a small fee to call the cops, which better companies will cost a bit more, but will be easier to catch and arrest the burglar.
•Finally Sims who called the cops to catch the burglar, or arrested themselves, will be reimbursed with a amount of money.
If the objects taken were expensive, they will be paid more. Similar to fires. Also burglars will be more attracted to expensive items.
Hope this list will help with improving the game!
