Nowadays, in various important examination occasions, such as the high school entrance examination, the college entrance examination or some professional qualification examinations, the monitoring and management of the examination room can be said to be a big concern! Many people are worried about whether there will be cheating during the exam, which will affect the fairness of the exam. This is really a headache! So, Exam Hall, that is, the examination room monitoring solution, is particularly important. It can use various technical means to ensure that the examination can be conducted in a fair and just environment.
First of all, we have to figure out what this Exam Hall is. Simply put, it is a complete set of comprehensive systems for real-time observation, recording and management of the internal situation in the examination room. It often uses various technologies such as camera shooting, recording, and signal shielding. The purpose is to do its best to prevent candidates from cheating and ensure that the examination can be carried out normally and fairly without interference from various adverse factors.
So what key content modules does this monitoring system mainly contain? Don't rush Exam Hall Surveillance Solutions, I'll disassemble it for you:
1. Video surveillance part: This is the most core part of the entire system! Generally, high-definition webcams are installed in every corner of the examination room, such as the front, back, left and right of the classroom, and some can rotate 360 degrees, for fear of missing any place! These cameras must ensure that they can clearly capture every move of each candidate. Even the small movements of lowering their heads and secretly watching the papers of the people next to them can be taken clearly, making it easier for the invigilator to view the real-time situation of the examination room at any time in the monitoring room.
2. Audio acquisition module: It is not enough to have images, and the audio aspect cannot be left behind! Some highly sensitive pickups will be installed in the examination room to collect the sounds of candidates' speech, as well as the sounds of turning the papers and writing with a pen… If candidates whisper to each other, or make any abnormal movements, the system can immediately capture them and promptly remind the invigilator to deal with them.
3. Signal shielding device: Nowadays, technology is so advanced that many cheating uses electronic devices, such as sending answers with mobile phones and receiving signals with micro-headphones. Therefore, the signal shielding module is essential! It can block the mobile phone signals within the examination room, as well as the signals sent by walkie-talkies and wireless routers, making candidates who want to cheat on electronic devices unable to succeed. This is really a useful way!
4. Storage and review functions: The videos captured and recorded audio data must be saved well, so the system will be equipped with a large-capacity hard disk recorder (NVR) or cloud storage server. These data generally have to be kept for a long time, for example, for several months. If someone reports that he suspects cheating after the exam, he can be retrieved and viewed the video at that time to verify whether this is true.
5. Intelligent analysis system: Nowadays, many advanced examination room monitoring systems have also added intelligent analysis technology, such as face recognition! You can compare with the photos of the candidates when registering to see if they are here to prevent someone from taking the exam; there is also a behavioral analysis function. If the system finds that the candidates have multiple times of looking around and passing things, they will automatically issue an alarm to remind the invigilator to pay attention to the candidate.
Here, I will answer a few questions that you may be concerned about:
Question (1): Will installing so many cameras and sound pickup equipment in the examination room violate the candidate's personal privacy?
Answer (1): Actually, you don’t have to worry too much because the examination room itself is a very special public place where candidates take the exam, and their behavior needs to be supervised to ensure fairness of the exam. Moreover, the audio and video data collected are strictly confidential. They can only be retrieved and checked when handling examination cheating or conducting compliance inspections. They will never be leaked out to infringe upon the privacy of candidates.
Question (2): Will this signal shielding device also interfere with the normal communication of residents around the examination room?
Answer (2): Generally speaking, it won’t be possible! The shielding range of a regular signal shielding device can be adjusted. Technical personnel will accurately control it within the small range of the examination room and will not exceed the walls of the examination room too much, so the impact on the mobile phone signals of the peripheral residents is very small and almost negligible.
In the market, there are also some small brands of examination room monitoring equipment. The prices may sound quite attractive and cheaper, but I advise everyone not to look at these bargains! The stability and functionality of those devices are simply incomparable to those of big brands. It is likely that something will happen in a while, which will affect the monitoring effect! Therefore, everyone still has to choose products produced by regular manufacturers, such as brand equipment that has passed ISO quality certification. Although the price may be higher, the quality is high! stability! After-sales service is guaranteed! It is necessary to remind you that if the school has the need to purchase such weak current intelligent products, especially if it is necessary to purchase globally, it will provide global procurement services for weak current intelligent products! Their family is quite professional and reliable in this regard, so you can learn about it.
Personally, I think Exam Hall is a very important technical guarantee for maintaining the fairness of the exam. When choosing and installing these systems, schools and examination organization units must comprehensively consider their actual needs and budgets, and choose cost-effective and mature solutions, so that they can truly play their role and make every exam go on fairly and justly.
