As a voice communication solution based on network transmission, the campus IP intercom system has been increasingly widely used in daily security management, teaching coordination, and emergency communication in various types of schools. Many people who don’t know much about this aspect may ask, what is this campus IP intercom system? To put it bluntly, it is actually connecting intercom terminals scattered in various places such as the school's existing local area network or dedicated IP network, such as the gatehouse, the corridor on each floor of the teaching building, the student dormitory building, and even the sports venues, so that a system device can be realized with a point-to-point, or multi-point-to-multipoint real-time two-way call function.
1. When selecting equipment, please pay attention to compatibility : when purchasing front-end intercom extensions and hosts used in the management center, all these devices must be confirmed in advance whether they support the standard SIP protocol? Or can it be compatible with the school’s existing network switches and campus communication management platforms and other networks? If it is incompatible, it will be troublesome to install it at that time, and you may have to spend extra money to buy other conversion equipment, which is not worth it.
2. The transmission network must be stable and reliable : all the communication data of this system is transmitted through the network, so is the network bandwidth in the campus wide enough? Is there any packet loss? What is the approximate network latency? ——These aspects must be thoroughly and carefully tested. It is recommended that the intercom system be divided into an independent VLAN, so as to effectively avoid network congestion and prevent other useless network signals from intercom system from being intercom system.

3. The deployment location should be scientific and reasonable : On the side of the teaching building, it is recommended to install one in the staircase entrance or corridor passage of each to two floors where the conspicuous and easy to reach; then the student dormitory is next to the gate of each dormitory building, and the middle of the corridor on each floor; for some important places in the campus, such as the guard duty room at the school gate, the school's chief monitoring center, and the canteen operating room, the laboratory must be installed, and the sound pickup effect must be ensured to be heard clearly in noisy environments.
1. The noise reduction function is powerful : when class is over in the school corridor, there are many students and very noisy, and there are intercom terminals in the playground and canteen, which are very noisy. You must choose a device with a professional noise reduction algorithm… This will ensure that the call sound is clear and there will be no strong background noise affecting the call quality.
2. High efficiency in radio search : For example, if a student suddenly has a fever and feels uncomfortable, or if he forgets to find important documents in a certain place and is anxious to find them, teachers or school administrators can directly send a designated area, such as the entire teaching building or a separate dormitory building, and even accurately reach a certain classroom to broadcast and call for searching people in the entire district or in the district, greatly improving the efficiency of finding people or conveying emergency information.
3. Be sensitive to night alarms : at night, for example, when the lights are on the rest time in the student dormitory, if a student needs emergency help due to an emergency incident, after pressing the emergency help button installed in the dormitory – this help signal must be within a few seconds. In about 3 to 5 seconds, it can be immediately transmitted to the host of the school's security center, and the accurate room number location information can be displayed at the same time.
Q: If the switch suddenly powered off, can this IP intercom system continue to be used?
A: Generally, better, formal brand, and guaranteed quality campus IP intercom system equipment will be considered to use two solutions to ensure continuous continuous… First, its terminal equipment supports power supply through PoE network cables. If the UPS uninterruptible power supply is installed on the switch – UPS is the backup power supply that can temporarily power for a short period of time after the power outage, it can support a short period of call demand. 2. The terminals in some key areas can also add a DC backup battery module. When the system detects an interruption in the incoming point, it can automatically switch to the backup battery in a very short time to continue to temporarily power supply, ensuring that in an emergency situation, it can last at least more than half an hour of call time.
Q: Compared with the traditional intercom system that simulates telephone line, in addition to the advantages of using this IP intercom on campus, will there be anything to pay attention to?
A: In comparison, although the transmission line of the traditional analog intercom is relatively simple, the device scalability is particularly poor! If you want to add new intercoms or repair lines, the workload will be particularly large. However, the IP intercom system is different. You can directly rely on the network to add the IP address of the new terminal device, and then simply configure it in the background… and then add and adjust it. However, technical managers have made requirements, requiring them to understand the basic configuration of the network and the simple daily maintenance of the system, so as to ensure long-term reliable and stable operation without interrupting communication
Personally, I think that in today's schools, especially universities or boarding middle schools with a large number of students, a large campus area and a complex layout, it is necessary to spend some money on a high-quality and complete campus IP intercom system; this is not only to improve the daily management efficiency of the entire school. Campus IP Intercom Systems, but it can indeed play a particularly important and critical role in ensuring the safety of teachers and students at critical moments! But when installing and choosing, you must be careful not to omit it… Just follow the methods and principles shared above to practice.
