As more and more families are considering upgrading their living safety, smart door locks are undoubtedly one of the entry products for users. First of all, it is clearly pointed out that the current technical level of smart locks makes users more relaxed and has certain security, such as face recognition unlocking, remote guest access unlocking, and the door will automatically lock after the user enters the door. Secondly, during the epidemic prevention period in 2020, it can also provide some guarantees in personal protection and safety.

　　In order to enable other smart home devices, including mobile phones, to communicate, smart locks need to use three standard communication protocols. Today, Xiaobian will briefly analyze the differences between various agreements with you.

　　Bluetooth

　　One of the main advantages of Bluetooth with keyless lock is that its battery life is more economical than WiFi. If the user uses the smart lock under normal circumstances, and the number of entry and exit is reasonable, the battery should be able to use Bluetooth for one year.

　　Another key advantage is the seamless integration of Bluetooth lock and smart phone without any third-party hub. If the user’s smart home needs are limited to keyless entry, and there is no need for any other equipment hub, then Bluetooth will be a wise choice.

　　The disadvantage of Bluetooth as a communication protocol is its small range, so how to configure it needs to be considered.

　　WiFi

　　Nowadays, many smart locks have WiFi connection as an optional additional function. Just plug in the device, you can remotely control the lock from anywhere online, but the disadvantage is that the network connection may be easily disconnected.

　　Z-Wave

　　Using a smart lock compatible with Z-Wave, you may need to buy another hub, and then you can convert the signal received from the lock so that the router can interpret and interact with it.

　　Z-Wave limits the connection range, so the connection is only suitable for more than 100 feet (about 30 meters) If the lock is not located at least near the hub, up to four expander devices can be used to enhance the signal to 500 feet or even higher. Users need to consider the budget of Z-Wave accessories according to the layout of the house.

　　With some Z-Wave locks, you can also access the lock interface within the application through the hub without a dedicated APP application.

　　Unless you plan to run multiple devices in a smart home outside the entrance and exit system, it may not be worthwhile to spend money on a smart lock with Z-Wave function.
