In fact, Evergrande is also involved in many other areas. For example, Evergrande also has a TV box. I just recently got this TV box produced by Evergrande, here to share details about this box and experience for everyone.
The Evergrande box is similar to most of the boxes on the market, and parts are also traditional "four-pieces": boxes, remote controls, HDMI cables, and power adapters.
The real body of Evergrande is like this. In the upper left corner of the box, there is a “healthy†label, which is a sub-brand of Evergrande and focuses on the medical and health field. This TV box is also launched by Ju-Health, which has a built-in poly-health channel. There is a deer pattern on the front of the box. This is also the logo of the poly health app.
Positive in the off state. The front black part is the power button. This button is very interesting. After the power is turned on, the power icon will light blue.
The size of the Evergrande box is very small, slightly smaller than the palm of your hand and can be held in your hand. Although the size is not large, but the weight is not light, take a little heavy feeling in your hand.
Hengda box is small, but the interface is very much! There are two sides of the four sides full of interfaces, the back from left to right is the LAN port, CVBS port, HDMI port and DC IN port. It is worth noting that copper is used at the HDMI interface. This kind of processing can avoid interface wear and cause screen transmission failure.
On the left is a dual USB interface and a Micro SD card slot, which is really too rich! For users who like to watch 4K video and download games with a box, it is undoubtedly a great boon.
The product name at the bottom of the display is "Gathering Internet TV set-top boxes," manufactured by "Shenzhen Hengda Digital Technology Co., Ltd.". Because of the small size of the interface, it will inevitably lead to a large amount of heat. Fortunately, the bottom of the cooling hole is very large, which greatly eases the heat problem.
With a 12-button design, there is one more voice control key than the 11-key of the millet box.
Similar to the volume of the box, the remote control of the Evergrande box is not large, holding it in the hand is too small.
The Evergrande box is normally powered on and turned on. The first position on the home page of the Evergrande Box is the entrance to “Healing Healthâ€. This is also the characteristic of the Evergrande Box. In actual use, the positioning of the top left corner of the homepage is very inaccurate. The author has targeted Guangzhou in Guangzhou.
In terms of content, Evergrande's box fully uses the content of Hua Digital TV, and basically the most popular movies and TV series can be seen.
Watch the hit drama "Joy of Ode", the actual playback effect, playback smooth and clear.
In terms of applications, Evergrande has prepared 20 selected applications for users. Although the quality is very high, but everyone's needs are far more than these! It is recommended that you install the sofa butler application market so that you can download TV applications as you like.
Visit the sofa network (), download the sofa butler package on the home page, copy it to the U disk, connect the U disk to the USB interface of the Evergrande box, install the sofa butler, and everything goes well.
The initial experience of the Evergrande box is here. For more detailed information on Evergrande Box, please pay attention to the "Sofa Manager" WeChat account number.
What is a wireless AC controller? What does it do?
Wireless AC controller is a kind of network device, such as the AC100/150 of Fengrunda, which can be used to centrally control and manage wireless aps. It is the core of a wireless network and is responsible for managing all wireless aps in the wireless network. AP management includes: delivering configuration, modifying related configuration parameters, RF intelligent management, and access security control.
Why use a wireless controller, and what exactly does it do?
In fact, the role of the wireless controller is to play a gateway function between the WLAN and the Internet (on the router), and the data from different access points are aggregated and accessed to the Internet. The role of an access point (AP) is to complete wireless access, and it can control user access through network flags.
The role of wireless controllers
1, Flexible networking mode and excellent scalability
The AP does not need to be directly connected to the AC, so that the AP can be deployed in any place that needs to be covered through the network, such as you deploy an AP in each employee's home, and then connect to the wireless controller inside the enterprise through the VPN, you can expand the wireless network of the enterprise to the family of each enterprise member.
2, intelligent RF management functions, automatic deployment and fault recovery
Through the dedicated RF management module, we can initially estimate the AP deployment according to the user's architectural design drawing, and can calculate the average bandwidth of the wireless terminal, the coverage between AP and AP in the actual debugging process.
3. Centralized network management
All the configuration of the wireless network can be completed by configuring the wireless controller. For example, enable, manage, and maintain all AP devices and mobile terminals, including all functions such as radio wave spectrum, wireless security, access authentication, mobile roaming, and access users.
4, powerful roaming function support
The wireless controller uses AP as the boundary combined with fast RF management system, which greatly reduces the connection time between wireless client and AP, and thus realizes the function of fast roaming.
5. Load balancing
AP and wireless controller systems can distribute wireless users or terminals to nearby aps within the coverage area of an AP, ensuring the number of each wireless terminal or the sum of AP bandwidth transmission or the upper limit of each wireless terminal bandwidth.
6, wireless terminal positioning, rapid fault location and intrusion detection
Wireless controllers can track and locate the location of wireless terminals, such as wirelessly connected computers, PDAs and Wi-Fi mobile phones.
7, powerful access and security policy control
At present, the wireless system supports authentication of 802.1, WEB authentication, MAC, SSID, VPN, etc., and supports various encryption modes such as WEP, WPA, WPA-PSK, WPA2, etc., and all configurations can be configured globally through the wireless controller.
8, Qos support
AP and wireless switching systems can limit the maximum bandwidth of a user's wireless connection within each user's privileges. For different IP services, the system can also define different QoS queues through the wireless switch module. For example, for wireless voice applications, SIP and RTP protocols can be set in the high queue, while common applications such as http and ftp can be set in the low queue.
The wireless controller AC is more advanced than the AP, plays the role of manager in the wireless network, and the wireless controller AC also acts as a client to complete a series of functions in the wired network (such as authentication, authentication, etc.). However, wireless controller AC is not a WLAN device specified in the 802.11 protocol family, but as a supplement to the protocol in specific applications, and its price far exceeds that of ordinary access point (AP) devices.
In small-scale wireless networks that use only a few aps, it is not economical to use expensive wireless controller AC equipment. However, if the number of wireless aps is large, more than 20 can be used AC controller.
