In many system integration projects, there are application requirements for intercom systems, which play various roles in different environments. So what are the intercoms currently involved? What is the difference between them?
Public Network Intercom
The intercom requirements mentioned in some projects refer to public network intercom, which is generally applied in mobile environments. Simulate the usage scenario of the walkie talkie through a smartphone, use the data of the phone to complete the work of the walkie talkie. This method is currently known as POC (PTT Over Cellular) for public network intercom.
Due to its unique working mode, it has significant advantages compared to traditional walkie talkies. The transmission of intercom data through 4G/5G traffic can meet traditional intercom requirements and avoid the complex engineering design of deploying base stations and relay stations. The project implementation is very convenient.
At the same time, public network intercom can also achieve video calls, GIS positioning, and message transmission. More intelligent services can be achieved on the basis of intelligent three proof terminals.
How to deploy a public intercom system?
Deploying a public intercom system is generally very simple. A set of public network intercom scheduling and command system servers can be deployed on cloud platforms or servers. The supporting three proof intelligent terminal can be used online. The function of the dispatch console can be achieved through a computer. The simplest public intercom system has been deployed in this way. It can meet the intercom scheduling and management functions of various industries. The advantage of independently deploying such an intercom system is that it can expand more diverse applications. Configuring cluster intercom gateways, telephone gateways, video gateways, and other devices can integrate intercoms, telephones, video surveillance, drones, etc. into the entire public intercom system. Combined with the dispatch console, intelligent terminals can achieve richer business integration.
IP intercom
Another type of intercom is IP intercom, which is also a commonly used intercom method in our projects. We have seen intercom help terminals in stations, venues, parks, and banks, which are this intercom method.
In fact, this intercom terminal is a SIP telephone terminal, which is only used in special environments to achieve one click dialing through buttons and communicate with backend service personnel through intercom.
This type of IP intercom is very simple to implement, usually using an IPPBX switch as the system server, configuring dedicated IP phones for service personnel, and arranging IP intercom terminals at the front end of the application. It can be achieved in many unmanned scenarios, where customers can quickly connect to the phone of the rear service personnel through button pressing, enabling communication.
This IP intercom can be said to be a fast two-way voice call. The application scenarios are very wide, easy to use, and the deployment and implementation are simple. Currently, there are also many types of terminals. It can support videos, call on-site cameras, and provide switch signals to achieve unmanned operations such as remote door opening and remote pole lifting.
At present, the network-based intercoms involved in communication integration projects mainly fall into these two categories. Public network intercom is generally designed for mobile environments, emergency situations, security, work scheduling, and other environments. IP intercom is generally used in fixed locations to solve unmanned problems, such as access control, parking lots, and other environments. There are also emergency call and alarm applications in environments such as stations, airports, parks, etc.
