Educational cameras are quietly emerging in the context of the current era where COVID-19 is affecting the world. After weighing the quality of education to ensure the health and safety of teachers, students, and other related staff. Online education through live streaming becomes a better solution. Although as early as more than 10 years ago, there were similar Harvard University open classes that used a video recording-sharing format to share quality courses with the world. However, due to the limitations of camera technology and network transmission technology at that time. The clarity and smoothness of the video are unsatisfactory. In today’s highly developed technology, we have more new products and technologies, so how can we choose the right educational camera becomes a problem.
To choose the right educational camera, we mainly consider the following factors.
1. The form and size of the class
At home or office, in the form of video, one-to-one, or one-to-many video classes, in this scenario, you can choose plug-and-play USB cameras, which are easy to use, and mostly fixed-focus cameras, which can ensure that your avatar is in the center of the screen.
In the classroom, through the video system, as the university opens class lives, the class live broadcast to the public, in this scenario, you will need a camera with a zoom function to ensure that your subject can enter your picture, for example, the classroom has 40 square meters, you can choose 3 times or 10 times zoom camera.
2. Compatibility & Transmission interface
No matter what kind of camera, is used on the network must be compatible with the current mainstream online communication system, general personal use, for example, Eyqoo’s EK81U or EH6xC, is a USB interface, with built-in software that can be adapted to the current market mainstream online communication software. And large classroom use of PTZ camera, for example, Eyqoo’s EK92AM or EH72US, is necessary to consider supporting SIP protocol and increasing the demand for hollow. It needs an RS232, SDI, or NDI interface to achieve long-distance, high-quality transmission, and control of the picture.
3. Resolution & Image capture capability
At present, Eyqoo’s camera resolutions are in 1080P or 4K, they have more than 2 million and 8.5 million pixels respectively, which can fully meet your various needs. At the same time, Eyqoo’s camera also has better software adaptation and AI function, making the picture display better and reaching 30FPS in 1920×1080 resolution.
4. Transmission speed
In addition to the recording class on the video real-time transmission needs are low, the rest of the use scenarios for video image compression and transmission speed have high requirements. Currently on the market universal interface mainly USB, SDI, and HDMI three, including USB plug-and-play, in the case of sufficient light, clearer, the most convenient to use, the most cost-effective, and suitable for personal use. HDMI interface bandwidth accounted for a small, fast transmission speed, but was slightly more expensive, and more suitable for some commercial scenarios. The SDI interface transmission distance can be farther, but with its reliance on professional-grade cable for transmission, the need for wiring, and related technical support, the price will be more expensive.
So, according to the specific use scenario, to make a more reasonable choice. Eyqoo has a professional pre-sales / after-sales team, please contact us immediately to get more professional guidance and make a more reasonable choice.
