What are the three mainstream technologies used in smart locks?

Smart locks are the most mature products in smart home products and are the first smart products to enter the user's home. As the most popular product, the technology used by the company has also received a lot of attention. So what are the mainstream technologies used in smart locks? Xiao Bian has summarized three here.

Main technology adopted by smart lock

The first kind: Bluetooth technology

We are more familiar with the Bluetooth function, Bluetooth technology developed from the 1.0 version to the latest 4.2 version, the function is also more and more powerful, of which 4.2, Bluetooth has greatly enhanced the application of Internet of Things features, can achieve a lot of new IP connectivity and gateway settings characteristic.

Compared with WiFi, the advantages of Bluetooth are mainly reflected in power consumption and security. Compared to the maximum power consumption of WIFI 50mA, the power consumption of Bluetooth 20mA is much smaller, but the disadvantages in transmission speed and distance are also obvious. Its maximum transmission speed and maximum transmission distance are 1Mbps and 100m, respectively.

In the field of smart locks, the Bluetooth unlocking function is the earliest one. The specific method is to unlock the phone through the Bluetooth matching between the mobile phone and the smart lock. However, due to the short transmission distance, the smart lock is not a fancy one. Practical features, so tepid on the market.

The second: WiFi technology

The application of WiFi wireless technology in the current era is extremely extensive. It can connect terminals such as personal computers, routers, and handheld devices to each other wirelessly. WiFi is a high-frequency radio signal, and it has the most extensive user and mass base.

In terms of technology, the main advantages of WiFi are reflected in the transmission speed and transmission distance. Its maximum transmission distance can reach 300m, and the maximum transmission speed can reach 300Mbps. The weakness is reflected in the power consumption, and its maximum power consumption is 50mA. And WiFi can easily access the Internet for remote connection.

The application of WiFi technology in the smart lock is currently the mainstream in the market. The smart lock has a built-in WiFi module and uses the router as a hub to realize the connection between the smart lock and the user and other smart devices. But WiFi's signal security and power consumption issues are currently one of the shortcomings of this technology.

The third kind: ZigBee technology

Relative to WiFi and Bluetooth, ZigBee can be considered as upstart. ZigBee is a wireless communication technology. Currently, ZigBee is mainly applied in the field of smart homes and has a good relationship with many smart home equipment manufacturers.

As a short-range wireless communication technology, ZigBee's advantages are reflected in low complexity, self-organization, high security, and low power consumption. In addition, ZigBee has networking and routing features that can be easily embedded in various devices. In terms of power performance, ZigBee performed best among the three, and security was between WiFi and Bluetooth.

Now there are many smart locks using ZigBee technology, such as the purple light smart door locks, Nanjing Wulian smart door locks and so on.

These three technologies are currently widely used in smart locks. At the same time, these technologies can also be applied to smart home systems to provide security for users' families.
