How to identify true and false digital intercom system

For the time being, digital video intercom is in an accelerated period of development, both in the market and in technology, and has gradually become an important part of the digital home. It has three major elements: image compression, voice processing, and network transmission, enabling digital video intercom to integrate with other home multimedia products.

As the demand for digital products in the market has grown stronger, digital video intercom has gradually become a trend. Many manufacturers also agree with the advantages of digital video intercom products, and they all want to catch up with this "golden train". Many intercom vendors have focused their attention earlier on this. Some manufacturers have already produced and sold digital video intercom products, and some manufacturers are still in the research and development stage. However, the market for digital video intercom products is currently mixed, and half-digit and fake digital products are flooding them, making digital video intercom products greatly compromised in users' minds.

So, how to distinguish the true and false of the digital visual system? Mainly can be distinguished from the following points:

How to identify the true and false digital intercom system First, we must first check whether the standard TCP/IP protocol is used, and whether the transmitted video signal is encoded and compressed.

How to identify the true and false digital intercom system Second, look at the intermediate equipment, networking equipment is universal: At present, some use a dedicated switch, and some rename the converter to a switch, etc., these need to pay attention to distinguish. In general, real 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 real digital products are standard and universal.

How to identify the true and false digital intercom system III. Look at the interface: When purchasing the product, we should carefully observe the interface of the door machine, the center management machine, the indoor unit and the wall machine to see if the RJ-45 interface is used, if not RJ- 45 standard interface, certainly not a digital intercom device.
