The live person meeting sounds the most direct and simple, but it has wasted a lot of manpower, material resources and time to gather participants from different places. The huge enterprise communication cost makes the government, enterprises and institutions, distance education and financial institutions, which travel most frequently, naturally become the largest potential customers of the video conference system.
The existing conference system in the market is mainly divided into two types of software and hardware: pure software video conference, whose cost and threshold are undoubtedly the lowest, can be completed by mobile phone, but the picture and radio quality are far from the special hardware, and it is difficult to avoid the jam and disconnection. The hardware only video conference system has the best effect, but the equipment is expensive and needs special maintenance. It has high requirements for operation, environment and network. The high price makes small and medium-sized enterprises seldom use video conferencing even when they realize the importance of video conferencing.
The gap between software and hardware has left huge market space for manufacturers, Just like the previous router, TV and camera fields, the wave of intelligence will eventually come to the video conference system market. And the first group of smart products in this field, which just landed on Taobao , let's take a look at this one now It can replace TV, HD camera, several microphones and other customized video conference equipment.

Appearance and design
The kraft paper box of the Wisdom Club is relatively simple, with simple product selling points and production information on the back.
In addition to the machine body, manual warranty and repair list, it also includes specially designed magnetic charger. The maximum output of the charger is 5V/2.4A, a total of 12W, which is manufactured by Tianbao Electronics.
The appearance design of the Wisdom Club is very simple, and it won the iF Design Award in 2017. Behind the round glass is a 7.95 inch 1027 * 768 resolution 4:3 screen. On the top of the screen is a powerful fish eye wide-angle lens. There is also a microphone hole in the upper right corner of the screen.
See Smart Club adopts rare polycarbonate+glass fiber material, which looks like anodized aluminum alloy. The fuselage bracket is wrapped in soft plastic, with a bright brand logo on the front and back. The overall weight is 1.6kg, which is quite powerful.
There are power buttons and touch sensitive volume sliders on the top of the show, and hollowed out speaker openings on both sides.
The shape at the bottom of the Wisdom Club is inexplicably cute. The round holes on both sides are the outlets of the bass inverted phase tube. The gasket of the base is also the interface cover, and the SIM card, micro SD card slot and mirco USB interface are below.
The magnetic suction interface of Wisdom Club is very creative. The shape of the round hammer is connected with contacts, regardless of the positive and negative. The magnetic force is strong, but it will not affect the rotation. The use experience is good.
System and hardware quality
For the first time, users need to log in or register, and can use it according to the guidance of networking. The machine can be bound and connected to an app called "personal phone". Its UI design is simple and easy to use. Its basic functions are similar to common communication software. It supports the sending of text, pictures and videos, even handwritten text, and can also make direct video calls.
See the Wisdom Club In fact, it is a very complete 4G tablet It is equipped with a highly customized OS 2.2.0 system. The main interface is designed in conjunction with the fuselage, which is circular, In addition to the core video call, the system has built-in cameras, calendars, notes, weather, network music, radio and video, and even crosstalk. The partners of the Wisdom Club include Youku, Xiami Music and Dragonfly FM. The apps of all parties have been deeply customized, and the UI design is quite cool and beautiful.
Two 2W loudspeakers are equipped in the Wisdom Club. Each speaker has a diaphragm unit with a diameter of 40mm. Although the power is not large, the size of the unit is impressive, and there is a bass inverter tube (responsible for converting the bass energy transmitted to the fuselage into phase and then outputting it to improve the conversion rate of bass power). The actual sound performance is far beyond expectation. The front of the machine is 5cm away, and the volume easily reaches 95 decibels. The side volume even exceeds 98 decibels, which is more than enough for square dancing.
Even at the extreme volume, there is no broken sound or jitter. The physical maximum volume of these two 40mm stereo units may be much higher. See the Wisdom Club The overall sound orientation of is mid low frequency, the mid frequency voice is close to the ear, the voice is warm, and the density is high, which is more suitable for the performance of male mid low voice; The sense of low frequency is sufficient, and the elasticity and cohesion are excellent. It is very pleasing in the short and fast low-frequency bursts such as drumbeats. In terms of sound quality, even if it is used as a speaker, it is very competitive. It is enough for many smart products that advocate sound quality.
In terms of radio reception, the conference uses a three channel microphone array. The main microphone is on the upper right corner of the front screen, and there are two sub microphones on the upper right and lower right. The software part supports DSP echo cancellation Intelligent noise reduction, automatic gain control sound effect processing. The actual pickup distance is close to the official 8m. In the 20 seat conference room (6m in length and 6m in width respectively), even if the machine is placed at the door, it can clearly pick up the voice at the opposite corner, which is excellent. It can talk directly with mobile phones. Compared with the general flagship mobile phones, the radio reception of the Pro Viz Club is much more detailed and hierarchical. It has to be said that the specially designed hardware has great advantages.
Camera and video: ferocious effect
See for yourself that H1 is equipped with UltraPixel image sensor, 4 million pixels, 1/3 inch, unit pixel size of 2 microns, with F2.1 aperture and 150 degree wide angle fish eye lens. For comparison, the unit pixel size of the iPhone 7 Plus is 1.22 μ m, while that of the Samsung S8 is 1.4 μ m. Among the current flagship, the Google Pixel with the largest unit pixel is 1.55 μ m. In the field of photography, the biggest rule is that "the bottom is bigger than the bottom". The huge unit pixel size can bring higher picture tolerance and weak light imaging ability.
Love to play computer games The director showed his passion
In actual imaging, the tolerance performance is quite overbearing. Even the big backlight on the top of the head has no significant impact on the brightness of the characters in the middle. Even when the light is turned off and the back is the only light source, the face can be seen, which is amazing. In terms of details, although it is not as exaggerated as the official slogan "Fear no darkness", the extremely weak light performance obtained only by 4 million pixels is not too stressful for the current 1000 yuan machine.
Remake the screen effect
In the video recording mode, the advantages of tolerance and photosensitivity have brought about the anti sky light rush performance, and the strong light source on the back has not led to the change of front people's light measurement. This tolerance of the video environment does not require the user to choose the position and angle deliberately during the video conference. The most exaggerated one is the field of vision of the ultra wide-angle lens. The 150 degree field of vision can capture the corner objects 30cm away, and the full body photo can be taken when standing 40cm away. The obvious traces of distortion correction algorithm can be seen at the edge of the field of vision. The dolls at the edge also maintain the original rough contour, but as The picture in the middle will be slightly flattened.
Features: Six party video+multi-party free speech
For video conference products, in addition to the hardware quality of the radio and camera, the most important function is the software level multi-party video access and multi-source information flow management. In this regard, the main selling points of the meeting are:
Six parties can be online at the same time: The video conference function of the VIP Club can directly add group chat members to the address book. The real-time images of the members are uniformly arranged on the left side of the viewfinder box, and the maximum number of accesses has reached 6 It is impossible for most software solutions. Even though most of the members only use mobile phones to access the discussion, members from six places can also discuss together.
Site inspection: After multi-party access, multi video picture scheduling becomes the next problem to be solved. On the mobile phone end, Pro Viz will use a multi grid screen display similar to the monitoring video, and double click can directly enlarge a certain screen. At the meeting, because of the advantage of screen size, when maximizing the display of a certain picture, the other five pictures can be hovered on the left side. Click to switch directly, which is much easier and more convenient to experience.
Multi person discussion and free speech: In the conference mode, the difference between sound and picture and the actual time is about half a second, When receiving from multiple sources, See the Wisdom Club By default, there are echo and background noise cancellation processing. Multi party sounds can naturally overlap without interference, and the effect is good. This effect It is enough to complete multi party real-time low latency topic discussions. It will not be like the software video scheme, where the other party has to wait awkwardly for 1 or 2 seconds for each sentence before the other party can reply. It can achieve the effect of free speech very close to the real meeting, which is very obvious to improve the experience in fast or intense discussions. Real time sound sounds simple, but when the delay is reduced to a certain extent It makes people feel that the space has been opened.
Combination of software and hardware: screen projection and cross screen interaction
The Pro Visions official provided a cross screen interaction scheme of "Pro Visions H1+Projector+Pro Visions Wheat", in which the projector is designed to be used by TVs and projectors without wireless projection function, and is used to deliver the images of the Pro Visions Wisdom Club through the large screen. Although it will add a little delay On common TV products, see for yourself Miracast function can provide projection function by itself. The actual connection process is similar to that of mobile phone/tablet projection, which is better than using conveniently without pulling wires.
"See Wheat" is a mobile phone client used to expand the pickup range of the landline phone, and its use method is similar to that of the walkie talkie. When conducting one to many or numerous video conferences, Too far away Participants can use it to expand the scope of the meeting and improve the accuracy. This is a rare combination of hardware and software in the conference system, allowing landlines and mobile phones to perform their respective duties, and transferring voice information flow to the platform of the hands-on seminar for uploading and downloading In the meeting The mobile phone has become an extension accessory of the Wisdom Club, so as to enhance the bilateral experience.
In addition to the management function, the personal phone app mainly addresses the needs of mobile participants from other places and other parties to join the conference. It can be used as an independent video conference software without a hands-on meeting. It can also be deployed quickly on business trips or occasionally when customers need to join meetings. It is a very conscientious function for users with limited budgets. Of course, the radio and picture effects are limited by the hardware of the phone itself, and there is still a gap between the effect and the experience.
In terms of network demand, when the two sides are talking, the Wisdom Club will switch the definition according to the network environment. Although the official claims that the broadband above 3M can be used, in fact, even if the network speed is only 2M, the connection can be smooth, but the image definition will be reduced according to the network speed. If the broadband reaches 5M level, the definition can be fully opened. In addition, because the VIP Club supports 4G cards and voLTE calls Outdoor or conference environment without WiFi can also work normally. 4G network has great speed advantage, and its definition is higher than WiFi environment in most cases.
summary
See Smart Club is a special product extending from 2C to 2B. The ultra wide angle camera with 2 μ m unit pixel, three array microphone and dual 40mm speaker unit have crushed the cameras and microphones of many conference system schemes in terms of hardware specifications, and the tolerance and dark light performance of actual video images are indeed overbearing. The traditional video conference system has been out of proportion to the experience for many years due to the lack of competition. The traditional products of the same kind have huge advantages in terms of the price of the meeting, and the software and hardware have also been specially customized intelligent products, so they are no longer competitive.
