Smart Door Locks: Perhaps one of the best new features in home security tech is the advent of the smart lock. These locks can detect your presence automatically using Bluetooth in your smartphone or keyfob and unlock the door for you. The best digital door locks will also connect to your home automation system and inform other devices such as the smart thermostat that you are away and to enter into energy saving mode. While Bluetooth locks are more secure, they have fewer features. Wi Fi locks on the other hand have more functionality, such as the ability to see if the door is locked in real time. However, the connection to the Internet also makes Wi Fi locks more vulnerable to online security breaches. 3. Home Sensors: There are numerous premium home security kits available now that will be able to sense your presence and open or close the door automatically. Home sensors can be installed on doors and windows and use motion detection, winks, and waves to determine your identity. They can be controlled from a smart phone or tablet easily. Additionally, home sensor kits detect movement in hallways and rooms.
