answer:The best “security” is to have someone in the home. That is, a trusted tenant, housesitter, mature and capable family member, etc. The house needs to be occupied or it will always be a target in an iffy neighborhood. Even if you have “a good security system” on an unoccupied house it will still be targeted by vandals and low-skill burglars. Security systems in general are intended to alert home occupants – especially at night, when most people are asleep, and when most break-ins occur – that they are no longer alone and secure, and should not remain asleep. You can get systems that will automatically alert police and fire departments upon appropriate signals from the system, but then you run an even higher risk – depending on the settings established for the system – of setting off false alarms, which will end up costing you (the homeowner / executor / caregiver) in fees for the police and fire response to false alarms. (And then a corresponding lack of intensity in responding to continuing alarms.) Can you put someone in the house to live there?
