After a theft or break-in

What to cover first after a stolen package, a car break-in or a break-in nearby, and what to do with cameras that came with a house.

• A package was stolen from my porch: what cameras should I get? Cover the doorstep and walkway, and pick a doorbell that watches packages without a monthly fee.
• My car was broken into in the driveway: what cameras help? Night coverage, floodlight cameras, and how close a camera must be to read a license plate.
• A neighbor's house was broken into: how do I protect mine? Cover every entry point, wire the spots that matter, and add lights and a smart lock.
• My new house came with the previous owner's cameras: now what? Getting devices off the old account, deciding what to keep, and planning around it.
