I highly recommend the Ring security system.

I have a complete system with alarms on doors, windows, cameras on front and rear doors, and an interior camera. When away from home, the system will sound a loud alarm, turn on bright lights, notify me and law enforcement if there is an attempted break in. System also has a fire alarm that will notify the fire department and me if there is a fire. I can remotely turn on lights, radio, TV. It will also notify my neighbors who have the same system and we are on a network. It records any movement and I have been asked for my video by the Sherriff when someone broke into a neighbors car. My camera did not capture the culprits as was too far away, but she got a system right after that. It did record a bear on my back porch a couple of years ago
