Ten thousand sets are expected to grow by more than 60% compared to 2017, and the market size will be close to 20 billion. Wang Changhai believes that the home field will be the main battlefield for the future of the smart lock industry.

“In 2017, the sales volume of smart door locks was 8 million, which was doubled compared with the previous year, and the penetration rate of the Chinese market is currently less than 5%.” US smart home related sources revealed. In contrast, South Korea's smart door lock penetration rate is 60%-70%. Similarly, Liu Jiangfeng, the CEO of Advantage Technology, also believes that this will be a market of 30 billion to 40 billion. "There is no head brand yet, which is a huge opportunity for everyone."

Investment institutions also favor the smart lock industry. First, in early March, Yunding won the investment of the blueprint venture capital, Lenovo Star, the peak and investment of 110 million C + round of financing; and on March 21, Deschman won the Red Star Macalline, good wife group And share investment and other well-known enterprises and investment companies to invest more than 100 million yuan; then on March 26, Manshen received tens of millions of Pre-A rounds of financing.

In 2018, with the continuous maturity of the smart lock industry market education, consumers' acceptance of intelligent products continues to increase, industry promotion efforts continue to increase, and the penetration rate of the smart lock industry will be greatly improved. It will exceed 100%, and as the penetration rate increases, the smart lock industry will also usher in a new outbreak.

In addition, the 2018 smart lock will also show the following trends: 1. Consumer brands will emerge. 2. Cross-industry integration will be common. 3. Industry concentration will be higher and higher. 4. The trend of Internetization and integration into the AI ​​industry is obvious. 5. Safe, convenient and applicable will become the mainstream of the product. 6. Consumer group customization products are becoming more and more popular. 7. Online and offline integration will make purchasing more and more convenient. 8. Market services will have a professional team.

Under the craze of intelligent hardware, combined with the overall layout of the smart home market, we can find that the value of smart locks is increasingly prominent. Intelligent security is the most rigid product in smart homes, and door locks are the first line of defense for each location. Together with the unique application scenarios and integration space of smart locks, it is bound to become a smart home market for enterprises. The first step.

Too rapid development of the industry may not be a good thing. With a large number of enterprises investing in the smart door lock industry, it is naturally a lot of problems. The following problems exist in the development of intelligent door locks: the reliability of technology, network security, the relationship between combined unlocking methods, and cost issues.

In addition, smart door locks want to usher in the true sense of popularity, is still an important part of the user's education, how to let users understand the advantages of smart door locks compared to traditional door locks, eliminate users for smart door locks Hidden concerns are one of the processes that must be experienced in the development of the industry.

Conclusion: As a smart lock for smart home security module, we want to achieve long-term development in the future development of intelligent home. In addition to continuing to develop our own advantages in products and channel services, we must cater to the trend of the Internet of Everything. In order to actively connect with IoT communication technology, integrate into the ecology of IoT platform, and build smart lifestyle together with thousands of smart home products, let people get a complete intelligent life experience, and coexist with many smart products. Therefore, smart lock enterprises must focus on the present, lay out the future of IoT, and use the "end" of smart locks to connect to the "cloud" of IoT.

Optical Coatings

• Single + Dual Wavelength AR Coatings (VAR / DAR):A single wavelength V-coat will provide reflectance less than 0.25% for 0° incidenceor 0.5% for 45° incidence at the chosen wavelength. Dual wavelength coatings will approach the performance of V-coats for two selected wavelengths. They are useful for optics which must transmit a visible alignment laser as well as a UV or near IR process beam. It is also useful for transmission of fundamental and first harmonic wavelengths.
• Broadband-AR-coatings:Anti-reflection coatings are offered to reduce surface reflections to a minimum. Two types of broadband coating are offered. A single layer of MgF2 on Fused Silica or BK7 reduces reflections per surface to about 1.5% over a broad bandwidth. If lower reflectance is required a multilayer broadband coating will provide an average reflectance less than 0.5% per surface.

• Protected + Enhanced Metallic Coatings (PAL / EAL / PAG / EAG / PAU / EAU)

  Metallic coatings make very broad bandwidth reflectors. Usually it is best to protect the coatings with a durable dielectric layer as they are very soft and susceptible to scratching. The efficiency of metallic reflectors falls off at shorter wavelengths but this may be enhanced by the application of a multi-layer dielectric thin film stack. The table shows the reflectance of each of the metals without any protection or enhancement. Protected metallic coatings have a dielectric coating layer over the metallic layer to protect the coating from being oxidized in the air or from scratched. For enhanced metallic coatings, a stack of dielectric layers are added on the metallic coating to increase reflectance for a particular wavelength range.

• Dielectric High Reflective Coatings:

1. Broadband HR coatings provide an average reflectance of 99% over a broad range of wavelengths. These broadband mirrors may be used for white light or multi-spectral applications.
2. Single wavelength, high power HR coatings are suitable for intra and extra cavity use. They provide the ultimate high reflectance of Rs > 99.8% and Rp > 99% for a specific wavelength. They may be used as a rear cavity reflector or for extra cavity use in beam delivery or turning. Note that Lambda high quality visible laser cavity coatings are designed for low scattering.

• Dichroic Beamsplitters – Beam Combiners – Harmonic Separators (SPD / LPD / BC / HHS)

1. Separate or combine beams with different wavelengths:Separate or combine beams with different wavelengths. These dichroic coatings allow one wavelength region to be transmitted while they reflect another region. They may be used as illustrated to separate or combine different wavelengths. This can be useful when working with alignment lasers or frequency doublers.
2. Dichoric Beamsplitters:These long-pass and short-pass coatings may be applied to any optical component to separate or combine different wavelength regions. They are available for normal and 45° angle of incidence. These coatings are highly effective for the wavelength of interest, reflecting over 99%. While they transmit over 85% of other nearby wavelengths, they are not blocked over a broad spectral range.

• Highly Transmissive AR Coatings For FLIR Applications:

Metallic coatings make very broad bandwidth reflectors. Usually it is best to protect the coatings with a durable dielectric layer as they are very soft and susceptible to scratching. The efficiency of metallic reflectors falls off at shorter wavelengths but this may be enhanced by the application of a multi-layer dielectric thin film stack. The table shows the reflectance. of each of the metals without any protection or enhancement. Protected metallic coatings have a dielectric coating layer over the metallic layer to protect the coating from being oxidized in the air or from scratched. For enhanced metallic coatings, a stack of dielectric layers are added on the metallic coating to increase reflectance for a particular wavelength range.

• IBAR : IR Broadband AR Coatings : Coatings for 3-5 µm and 8 – 12 µm bands

Infra-red broadband anti-reflection coatings are offered for the two broad spectral passbands of 3 – 5 µm and 8-12 µm. Coatings are designed for the refractive index of the substrate so it is necessary to offer separate coatings for different substrate materials. Standard coatings are offered for Zinc Selenide and Germanium. These coatings are highly durable and can be cleaned repeatedly using normal optics handling techniques. They are suitable for high power laser use such as that emitted from a CO2 laser.
