What is the difference between wired smart home system and wireless smart home system?
Smart home control system is divided into wired smart home system and wireless smart home system. For wired smart home system, the more common protocols in the market include KNX, can, bus, etc. the representative brands include Crestron, Hedong HDL, video GVS, control4 (also wireless products), etc. The more common protocols in the wireless smart home market include ZigBee, Z-Wave, RF, WiFi, etc. the representative brands include Xiaomi, orebo, Ziguang IOT, etc. Let's make an in-depth analysis of the difference between the two.
1. Stability
The bus smart home system transmits control signals through 4-core signal lines or network cables. There is no packet loss and interference, so there is no response or time delay after triggering a signal; Wireless smart home system transmits signals wirelessly, which is vulnerable to interference and has poor stability.
2. About construction
The construction of bus smart home system is difficult and the installation technology threshold is high; The wireless smart home system has the advantages of simple construction and convenient installation.
3. About cost
The cost of bus smart home system is slightly higher, and the price of wireless smart home system is low.
4. Application site
Bus system evolved from industrial control, so it is suitable for large-scale public construction projects such as airports, libraries and museums, as well as places such as schools, hotels, villas, clubs and families with high requirements for intelligent systems; Wireless systems are basically used in home environments where the area is not too large.
5. Functionality
The bus system has comprehensive functions. For example, in addition to the most basic lights, curtains and central air conditioning, it can also be connected with visual intercom, access control, background music, various control panels, floor heating, wechat client, etc. with perfect functions. The function of wireless system is limited to the development degree of the manufacturer, and the complex and personalized customization function can not be realized generally.
6. Logic
The wired system has great logic operation ability and can run various logic operations and scene combinations; The logic operation ability of wireless system is weak. Generally, it only runs lights, curtains and simple scene modes.
7. Compatibility
The wired system can be compatible with a large number of third-party products, such as monitoring system, access control system, background music, various types of panels, etc. the wireless system can only use the private protocol products in its own ecosystem.
8. After sales maintenance
The wired system protocol is open and has strong compatibility, so it is easier to replace parts, and the bus system integrator often has an excellent technical team, and the after-sales service speed is faster; The wireless system protocol is closed and can only use its own ecological chain products, so it can not replace other brand products. Technicians often rely on the technical support of manufacturers, and the speed of after-sales service is slow.
From a professional point of view, it is recommended that the choice of smart home should be determined according to the user's own needs and use environment. If users want to pursue cost performance and the house type is not too large, it is recommended to choose wireless smart home system, because the wireless system has the advantages of simple construction, convenient installation and easier price to be accepted by the public. If users want stability, comfort, taste and more humanized private customization functions, it is recommended to choose wired smart home system. After all, the smart home design function of mansions and villas is comprehensive, and integrators need to integrate and connect products of various international well-known brands, such as the monitoring system of Hikvision, the visual intercom system of Lilin, and the background music system of Austin and yearning, Daikin / Hitachi / Mitsubishi / Toshiba / Midea / Haier / Gree and other brands of central air conditioning, alian's security alarm system, Siri, Xiaodu, Ruoqi, Xiaobai and other voice control systems, Apple's homekit and so on.
