How NMP-based Smart Campus Saves Your Money and Time


How NMP-based Smart Campus Saves Your Money and Time


Nowdays, the smart campus is gaining popularity worldwide. As most of education institutions are gradually shifting their preference from traditional campus to smart campus. Traditional campus failed to make teaching and learning more diversified, colorful and efficient due to limited classroom multimedia devices. Although smart campus brings about more and diversified devices, they are all separated unit without being put under centralized control, thus posing a huge challenge to teachers, IT administrators, and school principal in terms of device management, device maintenance, security and energy-saving campus-wide. However with the introduction of NMP and web-based control platform and mobile app, things can be quite different. This article will help you find out how the device can be centrally controlled via Networked Media Processor that is reinforced by Q-NEX web console and mobile app for convenient and centralized control anywhere any time.

  1. What is Smart Campus?

Today, Smart Campus is not new to many of us, but few of us know what the smart campus really is. To be more specific, what actually constitutes a smart campus in elementary schools, high schools, universities and so on?

To answer this question, we need to focus our attention on the word “ smart”. Just like many other smart applications and experiences, for example in smart homes, where all  IoT devices such as a lamp, or wall-plug are connected and centrally controlled according to your predefined home automation schedule. Smart campus is pretty much the same, it is about data communicating and exchange among networked devices over internet using different control protocols for different actions and purposes.

The smart campus provides you with ubiquitous, reliable, wired and wireless connection and controls both indoor and outdoors for a wide range of smart devices for teaching, monitoring, broadcasting, announcement, room control, access control and so on in different application scenarios. Smart campus is designed to make life and learning easier for students, faculty and, and teaching staff, while at the same time improving the security, operations and resource management throughout the campus.

In a nutshell, smart campus connects smart IoT devices that are deployed for greater learning engagement for students, greater teaching efficiency for teachers, reduced maintenance workload for IT administartors, and easier all-in-one device control management for school principles, and enhanced security.

  • How did smart campus come to being?

When it comes to the question of why we need smart campus. I think we might need to stop for a few minutes thinking about it before we cloud possibly come up with an answer to it. Actually we can start about approaching the question by asking ourselves the following questions.

  • Why schools or university wants their campus to go smart?
  • What advantages does smart campus has over the traditional campus
  • What technologies has made the smart campus possible?

The primary goal for schools and universities to go smart campus is to stay competitive among their peers and to be management efficient. First, in order to stay competitive, school will need to digitalize their teaching equipment by using such devices as white board, projector, interactive display, document camera, teaching software, courseware, lecture capture recording system and so on, and these devices act in unison to improve the teaching quality and learning efficiency. More precisely said, students will be able to enjoy the classroom teaching with more engagement, amusement, thus improving their learning levels. Second, school with smart campus can better compete with their peers to attract students. As we know that education has always a top concern in many countries, and parents has been increasingly aware of the importance of sending their kids to a better schools with more advanced facilities through out the campus. So if the education institution goes smart with better reputation, they can stand more chance to attract more students. And this certain bring up the school revenues.

In short, smart campus helps schools to outperform traditional schools in its reputation, teaching quality, while minimizing the overall operation and management cost. And that pretty much explains why the smart campus is getting popular among schools and university and is becoming a trend of educational development.

  • What advantages does smart campus has over the traditional campus

Before answering this question. Its better for us to make a pause and think about the traditional campus is. Many of us have grown up learning in traditional campuses, so it wouldn’t be hard for us to image what a traditional campus looks like. Traditional campus usually come with a blackboard on which teacher and student wipe clean with a blackboard eraser, and write with chalk, wired microphone and so on. The whole class is almost not digitized nether is it equipped with any networked device. Furthermore, the students cannot be exposed to such resources as multimedia courseware on the display, nor can they bring home the teaching contents on the blackboard. Also, it can be hard for the student to catch up on the missed class when they did not attend school on that day, because the what is taught in the class would not be recorded for later use.

In contrary, the smart schools have all that networked smart devices used indoors and outdoors. For example, the device indoors can be interactive display, whiteboard, passive speaker, electronic curtain, document camera, smart pen, IP camera, lecture recording device, just to name of a few. This devices not only greatly facilitate teacher’s teaching but also enable teacher to better engage students with well-designed courseware, multimedia teaching resources and so on. Even if the students missed the class for some reason, they can still rely on the recorded lectures to make up for the class. Also, teachers can start hybrid teaching involving students who are in the classroom and those who are attending the video calls remotely.

  • What technologies has made the smart campus possible?

Without the technological advancement, the smart campus would not be made possible. And the development in, Internet-of-Things (IoT), AI (Artificial Intelligence), and AR (Augmented Reality) in particular has contributed greatly to the smart campus. Schools or universities have adopted these AV technologies in their campus to improve teaching and learning of educators and students.

First, the IoT devices are the basic elements in the smart campus. These IoT devices are all networked devices with different functions. When they are connected to the internet, then they can be controlled and managed remotely over internet, and work in unison with related devices for schedule device automation, for example a predefined schedule for certain device to be turned or off according to the schedule, and for hybrid leaning for people who attend the class virtually and remotely. In short, IoT devices are the prerequisite for the possibility of the smart campus.

Second, AI technology is what smartens up the IoT devices. For example, a AI lecture camera is capable of focusing the camera view on the teacher who are walking up to the blackboard, or students who are standing up for the answer. And if an interactive display comes with AI camera, students who are receiving a distance teaching can get to see class room view in front of the camera, while their voice will be amplified and transferred to the teachers and students in the class room for better collaboration, engagement, and interaction.

  • Devices deployed in the smart campus and its application

The smart campus devices can be mainly divided into two types, namely the indoor type and out door types. Generally speaking, the indoor type devices include white board, interactive flat panel, IP camera, lecture recording devices, projector, podium, speaker and so on. And you do not necessarily have to deploy all of them at the same time, you just need to select the devices needed for your application. For example, in the hybrid learning scenario that involves students learning from home, you will just need to select such networked devices as interactive flat panel, web camera or the speaker phone. If you want to broadcast live teaching to the students via such third-party video platforms, or record it for later use, you will need to further include a set of lecture capture system consisted of video station, auto-tracking cameras, ceiling mic. For out door device, it mainly includes IP camera, speaker and so on. These device is basically used for monitoring security and AV-based campus wide notification.

  • User and User experience

It is obvious that users in the smart campus are in the most part teachers, students, school principles, and IT administrators. Each of them has different role to play. For teachers, they can prepare and present their courseware on the interactive flat panel on which they can do whatever they like, for example drawing, writing, annotating to better engage the students with enriched teaching contents, while the students can learn with greater efficiency and amusement in the multimedia teaching. For school principles, they broadcast notification campus-wide whenever needed. And for IT administrators, they need to constantly keep an eye on the running status of the existing smart devices and fix the faulty device reported.

6.1 User’s problem in Smart Campus

Smart campus really brings teaching staff, principle, IT administrators a lot of wonderful experiences, but they all have their own respective difficulties. 

6.1.1 Problem faced by teachers

Teacher is having a headache in dealing with complex multimedia devices. As all the devices in the class are separated and located in different places in the class room, so teacher has to go here and there, for example to turn on or off the projector, the white board, and air conditioner, the document camera and so on. Worse still, for example, when teacher have to present pictures using document camera and the teaching material in their laptop, teachers have to do the plug and unplug to switch the input source for interactive display panel or the projector. It that case, it can be very troublesome and inconvenient for teacher to do so and affects teachers’ teaching efficiency. In addition, teachers have to turn on every devices needed before starting the class and turn off the device again when finishing the class. And it can be problematic if teachers forget to power off the device after the class, which can not only lead to potential fire hazards, but also drives up the power cost. Furthermore, when the device is having a problem, teacher might find it difficult to get in touch with IT administrators promptly for a quick fix. Furthermore, when teachers find their courseware cannot be opened with some errors, teachers has to struggle through the whole class with compromised teaching effect. And lastly if would take a lot of time for teachers to learn how to operate devices if the device are complex.

6.1.2 Problem faced by IT administrators

IT administrator is the one who takes careful of the all the networked devices through our smart campus. When many device are left powered-on, IT administrators will be having a hard time turning the power off for every individual device here and there, because it can be troublesome and time consuming for them to do so when the device becomes so many. And this can not be addressed simply by hiring more IT administrators. So how to save administrators from such repetitive operation every day? And it is more often not that, there seems to be lacking of early warning for the administrators to take preventive measure before receiving teachers’ complaint about faulty devices, therefore they have to deal with some many device problem at a time, but it can be very inefficient to get all them fixed one by one after problem occurs. To be more specific, IT administrators can not be constantly updated on the device usage and frequency to make device maintenance schedule accordingly, which is also true for power-saving for the frequently used devices.

6.1.3 Problem faced by Principal

Principle usually face two problems. First, how to save the management cost by reducing the number of IT administrators when the devices are getting higher in number, and how to make device maintenance more efficient. And how to put all the separated devices under one centralized control so as to cut down operation cost, management cost, and power cost, and how to do audio-video broadcasting campus-wide efficiently to such places as school auditorium.

Although the smart campus brings us lots of convenience and benefits, there still exist several problems pending for solutions. And NMP is a proven answer to it.

  • What is NMP and its advantage

NMP provides by Q-NEX stands for Networked Media Processor. It serves all-in-one central control unit capable of putting a wide range of network IoT devices that are connected to it under unified control via TCP/IP protocols. It is because NMP comes with a wide variety of interfaces and is able connect to all kinds of terminal devices. For example, it can be connected to independent AV equipment and electric devices. NMP comes with a control panel on which you can control the devices that connected to it. Which means if you have control over all terminal devices via NMP using the control panel, you can basically control everything connected to it.

  • What type devices can be controlled by NMP?

You can connect all kinds of multimedia products, IoT/Networked devices to NMP for a unified control. For classroom multimedia product, you can connect such device as wireless mic system interactive flat panel, web camera, lecture capture system and so on. for other electrical devices you can connect lamps, fans, air conditioner, electrical curtain just to name a few. And when NMP is connected to Cloud Sever, it just allows you to control the devices any where any time.

  • How you can control NMP on Q-NEX web console and Q-NEX app?
  • NexNEX web console is the web portal where you can control NMP as well as the terminal devices to it. And Q-NEX is pretty much a mobile version of the web console in your phone.

Once NMP is connected to the cloud server, users can simply log in to Q-NEX Cloud Server web portal or Q-NEX APP to perform all kinds of controls any where anytime without being onsite.

  • The deployment of NMP really brings users lots convenience.

For teachers, they can turn on or off the classroom multimedia devices with on tap on the touch panel or control panel attached to it, realizing one tap control for device power, AV-input source switching and so on. When teachers are away from school, they can either turn on or turn off the power on the Q-NEX web console or simply on their app with no worries. And when the teachers find anything wrong with the device, they can report it to IT administrators on the Q-NEX APP. And teachers can upload the file from Q-NEX before they can present the teaching courseware on the screen, without being affected by the error files in their laptop.

For administrators, they can be saved from repeated works, such as turning on or off the device manually at certain time during a day by predefining a certain automation task that will activate the device to perform certain task.

For example, you can either log in to the web portal or the app to check all the device that are connected to it and turn it on or off remotely, and you can even predefine a automation schedules for example to turn on or off the device daily at specific time. And IT administrators can check on device running status to turn it off if when any teacher forget to power off the device before they leave work.

For principles, they can cut down manpower cost for IT administrators and find out better way to save power, thus bring down the total cost in the smart campus management.

To sum up, with NMP, the previous terminal devices are no longer separated because they can all be connected to all-in-on NMP for a unified control, bringing huge convenience to all people involved on the campus. In the meantime, the convenience of NMP is reinforced by the Q-NEX web console and Q-NEX app, that allows users to control all the terminal devices including NMP wherever they like.For further information about Q-NEX solutions, please click here to contact us.
