With the continuous development of community intelligence, the demand for digitalization is getting stronger and stronger. However, people still don't have a thorough understanding of the concept of digital video intercom , they don't know enough about the products, and they bring great confusion when buying. The following Jiahua Guardian put forward some suggestions for the purchase of digital video intercom system, hope It can be used as a reference when you buy a digital video intercom system .
1. Imported brands are not necessarily better than domestic brands
The scale of residential communities in China ranges from a few hundred to a thousand, and it is dominated by apartment buildings. This is unimaginable in western countries with relatively small population densities. Therefore, the capacity of intercom systems in foreign countries is far less than that in China. . In fact, if only from the perspective of digital intercom technology and quality, some domestic brands have already reached or even surpassed imported brands, and in some aspects have greater advantages than imported brands. Therefore, do not fall into the misunderstanding that imported brands must be better than domestic brands.
2.Identify whether it is really a digital product
At present, digital video intercom is in a period of accelerated development, both in the market and in technology, and is becoming an increasingly important role for the digital home. It must have three major elements: video compression, voice processing, and network transmission. All audio and video signals must be digitally encoded and compressed for transmission over the network. Therefore, when buying a product, we need to see whether the product has an RJ45 interface and whether the intermediate networking equipment is universal. Generally speaking, these networked intermediate devices can be purchased directly from the market. If they can only be purchased from the intercom system supplier, it is certainly not a true digital product. The true digital product is standard and universal.
3. Product process design
Since the intercom system has been integrated into our lives and we use it every day, the craftsmanship appearance of the product must be close to the home style. In order to leave a good first impression to customers, intercom system products must also have exquisite appearance. Generally strong manufacturers will have multiple color styles and structural design styles for the same series of products. The choice of materials is also divided into high, middle and low grades. More importantly, the design concept and humanized operation design will make users feel very intimate.
4.Waterproof, tamper-resistant and vandal-proof
The door phone of the intercom system not only requires exquisite appearance, but also chooses good materials. VTO is facing the possibility of being destroyed at any time, therefore, the material it chooses must have certain impact resistance to prevent malicious damage by thieves. In addition, in terms of product design, there must be a good anti-disassembly design to prevent thieves and other criminals from easily stealing it. In the product's structural design and material surface treatment, the problem of waterproofing must be considered to avoid affecting the operation of the entire system.
5. System functions and integration
In addition to the functions of video intercom, remote unlocking, etc., digital video intercom products can also implement remote video monitoring, change alarms, access control systems, three-table copying, information release, smart home control, Internet access and video on demand and even Mobile phone linkage and other value-added services. Therefore, during the product demonstration, it is necessary to check whether these functions are available to meet the functional requirements of the residential area. To meet the current scale of community development, the system must be very powerful.
6. Performance indicators and field testing
The main function of the digital intercom system is still intercom, so the call sound must be examined, and performance indicators such as audio signal-to-noise ratio, distortion, and frequency response can be viewed. At the same time, the circuit board technology should also be examined to test the electrical indicators of the product, such as current, voltage and power.
