With development of a new round of information technologies, such as Internet of things and artificial intelligence, digital economy is fully integrated and penetrates into real economy. In terms of industrial digital transformation, we can say that security industry is leading way. Among them, digital intercom system is in a period of accelerated development, and is gradually becoming an important role in digital home.
Compared with traditional analog intercom system, digital intercom system has following advantages.
1. Ease of connection and low cost
One network cable can solve all problems, which greatly simplifies connection project. At same time, construction period is also greatly reduced, which reduces labor costs and subsequent maintenance costs.
2. Powerful network function
It is equipped with both a high performance processor and a DSP chip. Powerful data processing capabilities make network functions powerful and provide greater ease of integration with other security subsystems.
3. High scalability
It can not only realize video intercom, but also realize functions such as multimedia transmission, broadcasting, burglar alarm, smart home, IP video phone, VOD, video monitoring and value-added services.
The digital video intercom market is also relatively patchy nowadays, being flooded with semi-digital and counterfeit digital products. How to distinguish authenticity of a digital intercom system?
1. Check if standard TCP/IP protocol is accepted and if transmitted video and audio signals are encoded and compressed digital signals.
2. Check if intermediate equipment and network equipment are shared: Currently, some use dedicated switches, and some change name of converters to switches, etc. They need to be distinguished. Generally speaking, real network intermediate equipment can be purchased directly from market. If it can only be purchased from an intercom system supplier, then it is definitely not a true digital product. A true digital product is standard and universal.
3. Look at interface: when purchasing products, we must carefully examine interfaces of call station, central control station, indoor station and outdoor station, to ensure that RJ-45 interface is used, if not, standard RJ-45 interface is definitely not digital intercom device.
