One of the first lines of defense in home security is home access, including access to gates, property, land, and the home itself. It used to be that home access consisted of little more than a loyal dog to alert homeowners of approaching visitors or a bar across the door to keep it closed. Today, door handles combined with deadbolt locks secure doors, and many technological advances have provided many more options to improve home security. For example, intercoms, video monitors, and other advances make it simple to know who is at a door or gate and decide whether to allow access or not. Before making a home access purchase, buyers need to understand the different options available. The correct home access control for any situation varies depending on the features required, area of the home or property, and the amount of money the homeowner is willing to spend.
