Instead of using traditional keys to open doors, smart locks use the latest technology to lock and unlock your doors from anywhere. You can set up individual access codes for your kids or household help, which leaves a recorded trail of access to your home. Optimizable features and easily integrated software mean that you can link up your new smart system to your security cameras or motion sensors. These locks are extremely specialized and cannot be hacked open without database notification and can also be linked to your alarm system for greater security. While this system may be costly for some households and businesses, the list of benefits generally far outweighs the initial investment.
