This is a series we plan to develop dealing with securing the home. Some things will be lower budget as well as pointing higher budget items people employ to make their homes more secure.
No place is foolproof, but you can do a lot to enhance your home security. From the low budget such as Locks, wood blocks and bar inserts for a sliding glass door. Extra add-on locks for windows and and chains for the front door to full scale alarm systems and motion detectors.
If you've had luck with some styles of security, make suggestions. If you have ideas or questions, voice them.
Guard dogs, bells hanging on doorknobs. What works for you, what are you interested in.
