Vision became bigger, wonderful start again, cloud network line CRD2 hand evaluation!

[table=98%][tr][td] The visual field becomes bigger, wonderful start again, cloud network CRD2 hand evaluation!

I remember someone said that all women like to go to the cinema to watch movies, and men like to go home to watch movies. One is the emphasis on romance, and the other is on privacy. Therefore, under normal circumstances, the projections are all bought by men, and those who buy movie tickets are basically men, but they are all double-vote. I have enjoyed watching movies since I was a child. I used to play at the wheat field and watched the first open-air movie “Xiu Zhang Zhang Xi”. I was eager to have a home theater after I grew up. Now I have grown up, worked, and got married. When I was married, the dream of private cinema was still alive, but there were too many things to consider (mainly no money), so I couldn't do it with great fanfare. Noisy or necessary, played a few projection, dozens of high-definition boxes, tossed a few audio, but also drummed two screens, but when it comes to standards, they are all entry-level. For projection, originally intended to be on the 1080P theater projection, also because of the reasons for the lack of money, but also had to do it, they turned their attention to the micro-projection products, after playing several models, they found that for me this pseudo ( Zhen) hair (mei) burning (qian) silk, micro-cast really more suitable for me. Although the resolution is not as good as that of 1080P, the effect is still satisfying. Moreover, the price is cheap, and the worry of replacing the light bulb is eliminated.


Today, I would like to introduce this micro-projection to you. It is the latest product introduced by Dongguan Cloud Network in 2015. It is also the brand's first projection product. For cloud network friends, friends who like to play high-definition player should not be unfamiliar, he is a dedicated to research and development, manufacturing, sales, service in one, with Android system mini computer, FULL HD 1080P HD player, Bluetooth digital high definition home theater Audio and other 3C electronic products are the core business enterprises. Since last year, micro-investment has suddenly become a very popular product. Emerging micro-investment brands have sprouted up. Cloud Net Bank also spotted this huge potential market. So in early 2015, this model was introduced as CRD2's smart micro-projection products. It is equipped with 1.8GHz RK3288 quad-core CPU and 0.45DMD+RGBLED display chip, using the German Osram LED light source, with an ultra-long life of 50,000 hours. The 1280x800 standard resolution can play 4K movies and 3D movies. Such a product with a powerful configuration and devoted to cloud network pedestrians will bring us surprises in practical use. Let me unveil it for everyone! In order for everyone to have a general understanding of CRD2, let's take a look at this official configuration parameter table:



Cloud Network CRD2 adopts a double-opening outer package. The text fits with the icon display mode and does not display the projected pattern. This simple packaging promotion is difficult to bring a strong visual effect to consumers. It is suggested that the packaging should be focused and give people visual impact to increase the user's desire to understand and purchase.


The bottom of the box is the projection of the relevant parameter information.


CRD2 cloud network has two colors, wine red and black, this one is black, it seems more calm, wine red is more fashionable.


The complete machine accessories are also relatively simple, a host, a WIFI antenna, a remote control, a separate power adapter, a HDMI high-definition line, a set of instructions.


The CRD2's exterior design concept is said to have been taken from the shape of a supercar, but I wouldn't be able to put it together with a supercar for a long time. The projection body is a black piano paint process that looks relatively good.


The design of the upper and lower slopes makes the overall streamline of the machine more intense, perhaps it is to highlight the shape of the so-called super run.


There are very few buttons on the top panel of the machine. There are only 2D/3D conversion keys, MENU keys, and switch keys. In the power on state, click the MENU button to switch the input source.


On the back of the machine, there are WIFI antenna interface, TF card slot, reset hole, audio fiber output interface, wired network interface, three USB2.0 interfaces, power interface, infrared receiver window, 3.5mm audio output interface, 3.5mmAV Input interface, VGA interface and HDMI high-definition interface.


The cloud network CRD2 interface is very rich, not only taking into account the current mainstream HDMI high-definition input, but also taking into account the computer user and AV input. In terms of audio, the fiber output matches the 3.5mm standard audio output. Three USB interfaces can definitely meet the needs of simultaneous access of multiple devices in daily use, but there is no 3.0 interface is still somewhat regrettable. The front and rear bi-directional infrared receiving windows maximize the control sensitivity of the machine in different locations. Of course, if you can replace the 2.4G wireless technology with 360 degrees no dead ends, the remote control effect will be better.


The side focus ring feels good and has enough dampening to easily adjust the focal length to the best position. The built-in horn sound effect of the machine is still good, the volume is also sufficient to meet the daily use, but if you want to pursue a more intense auditory effect, you still have to connect external amplifier speakers.


In front of a large Osram lens, next to the infrared remote control and cooling holes. Do not know why, CRD2 did not design the lens cover, I personally think that for the projection, the lens cover is still very necessary, the importance of the lens does not have to say that everyone also knows, so in the daily use to protect the lens is a must of.


The detachable WIFI antenna has a strong signal reception capability and is much more sensitive than the general WIFI receiving device in actual use. Dual-band mode also makes video and entertainment more smooth.


The bottom of the machine is equipped with 4 rubber support pads and a screw hole for fixing, which can be mounted on most camera tripods. However, the screw hole is not located in the middle of the machine. It is not known whether it will cause one side to become heavy.


CRD2 adopts DLP display technology, supports active 3D, the official nominal brightness is 1500-2200 lumens, WXGA level with physical resolution of 1280×800, has a contrast ratio of 5000:1, and adopts the new LED source of OSRAM LED, environmental protection, Without any radiation, the maximum life expectancy is 50,000 hours and basically no lamp replacement is required.


The CRD2 uses a 19V 4A DC power supply. The power supply is two-phase and has a very solid workmanship. However, I personally think that as a portable micro-projection, there is no need to use such a large power supply. It is not only inconvenient to carry, but it is even more troublesome for daily household use.


The infrared remote controller of CRD2 adopts the design of a full-key position. The comfort of the keys is normal and the rebound speed is slightly slower. The response range is still relatively wide, and it is basically possible to reach 360 degrees without dead ends in close quarters, but occasionally the response will be slower. Through the above function keys can be switched source, trapezoidal manual correction and 3D mode switching, mouse mode is not very sensitive.


The remote controller uses two 7-cell batteries.


Randomly equipped 3D glasses, but this is not a standard accessory for CRD2, it belongs to the category of gifts, but I do not guarantee that it will be presented. But now the general 3D projection will give one, which is also a means of sale, send a picture, it is very likely that users will buy one or more of their own. If you don't send one at the time of purchase, it is very likely that the user will not buy one. This 3D glasses is still relatively high-end, in order to take care of users of different sizes of nose, also sent two different sizes of nose pads.


Along with the glasses, there is also a cloud network's own wireless squirrel. The wireless mouse, air mouse, and remote control are three-in-one, and the grip is comfortable in the hand. The double-sided design has a MINI keyboard on one side and a remote control on the other. And this squirrel also has a learning function, you can simulate TV buttons, used on the box more convenient, in fact, was originally designed for the box. The squirrel is also powered by two 7-cell batteries.


The following related parameters are tested in terms of equipment, technology, environment, and method are all amateurs, but they are only given to users in the personal capacity and can be a reference data, we do not have to care too much about the accuracy of their data, for reference only, Accept Paizhuan, welcome Tucao.
Power test cloud network CRD2 power fluctuations in the standby state of 1.68W, the network on demand in the case of 50W, mounted hard disk local playback slightly higher, about 52W. This power consumption tells the truth to be truly power-efficient. For example, the original CRT29-inch TV in my home is about 80W, the TCL's 42-inch LCD is about 160W, and the 37-inch is about 130W, so I used CRD2 to see it. In the case of television, one year, the optoelectronic fee can save one!


Noise Test For the projector, the noise problem is also a concern for many friends, because it not only affects the user's mood when watching a movie, but the loud noise is also likely to damage the user's hearing. Let's take a look at the difference in noise that is common to ordinary people:
0-20 dB: This level is basically not felt.
20-40 decibels: Quiet, whispering.
40-60 dB: General, normal indoor conversation.
60-70 dB: noisy, destructive nerves;
70-90 dB: It is noisy and the nerve cells are damaged.
90-100 decibels: Increased noise and hearing loss;
100-120 decibels: Unbearable, stay for a minute or temporarily deaf.
120 decibels or more: Extreme or full.
Because the professional test noise is performed in an absolutely silent space, the resulting data is more accurate. Of course, I certainly can not do it, can only do is choose a relatively quiet environment, the test time is early morning The appearance of 2 o'clock (nearly winter is near zero, really cold), still quiet around, the ambient noise is 35.5 decibels at this moment.


In order to achieve the relative accuracy of the data, I used a more common noise testing techniques - five-point fixed-point test. That is, in the front, back, left, and right directions of the object to be measured, the data is sampled using the same distance of 50 CM, and then the five data are averaged to obtain a relatively accurate result. From the figure below, we can see that the values ​​in the five directions are 49.1, 48.0, 47.5, 46.9, and 43.4, respectively, and its average value is 46.98 dB. This noise level is still relatively small.


Temperature test We know that light bulb projector has always been a large fever, if the movie is too close to the hot sweat, cold indoor air heating is not used, so the projection of heat has always been the user's attention A key issue, and micro-projection of such a small volume if the heat is too large will certainly affect the normal operation of the machine. What about CRD2's performance in this area? Take a look with me! The test time was 2 o'clock in the morning and the room temperature was 2 degrees.


About three and a half hours after the machine was turned on, the temperature measuring gun and the projector have been placed in the same environment for more than three hours. The infrared temperature gun test, the location of the machine's highest temperature in the front of the cooling hole, is 36.7 degrees. The lens temperature is 24.1 degrees, the maximum temperature of the upper panel is 20.8 degrees, the maximum temperature of the bottom panel is 30.5 degrees, and the maximum temperature of the power supply is 33.5 degrees. This data is definitely satisfying, but this data has a lot to do with the low ambient temperature at this time, so it will certainly rise a lot in the summer, but we can see from this test result that the CRD2 is under temperature control. What is done is still relatively in place.


Brightness test I believe that for the projector, brightness has always been an indicator that users are most concerned about. Here I would like to remind you that the high brightness of commercial projection is to meet the needs of use during the day, and most of the use of home projection The environment is in the evening, and most of it is used in a dark environment, so too high brightness will hurt your glasses, so I also advise that if you do not have special needs, the home does not need to pursue too high brightness. Of course, some of my friends who like watching TV with projections during the day can ignore my passage. For the brightness of this indicator will greatly affect the user's choice at the time of purchase, so basically all the projector manufacturers will deliberately raise the lumen of the machine in the publicity, which we are also accustomed to, in fact, the mainstream of the current market The micro-cast, the actual brightness is not very high. Let's take a look at how much the CRD2's true brightness is!
For a relatively accurate test, I used the ANSI 9-point test method, which measures the illuminance of the 9 center points in the picture. Then the average illuminance of the 9 points is the average illuminance of the entire screen, and then multiplied by the picture size. It also gives the brightness of the machine, which is ANSI lumens.
The nine-point LUX values ​​are 187lux, 201lux, 179lux, 216lux, 217lux, 203lux, 223lux, 222lux, and 213lux, respectively. The average value is about 207LUX, and then we multiply the area by 1.738 (the test shot is about a long shot size. 158cm, width 110cm), ANSI brightness is about 360 lumens.


Contrast Testing We know that contrast is also an important indicator for projections. A machine with a high contrast ratio has a clearer picture and brighter colors. The machine with low contrast will appear gray and turbid on the entire screen. In the test contrast mode, I also used the ANSI contrast test method, the same area of ​​the 8 black 8 white chart, the test data are as follows: ANSI contrast: (198+204+212+203+207+216+214+212)/(3.2 +3.3+3.3+4.3+4.2+4.4+4.1+4.6)=53:1


The virtual coke/scratch test is a DLP technology projector, and it will have its own special short board, that is, the problem of virtual focus and coke, especially the projection of the resin lens, these two problems are even more. serious. Under normal circumstances, many low-price micro-projections will use resin lenses for cost reasons, and then use technical means to minimize the phenomenon of virtual coke and coke, but they are basically universal. The CRD2 cloud network uses a relatively expensive glass lens, so the situation of virtual coke and coke is much better. After adjusting the focal length when the camera is turned on, the definition of the entire screen is basically uniform, and it is slightly blurred just below. After starting the work for a period of time, there is no case of running out of focus. As long as the position is unchanged on the second day of the boot, there is no need to perform another focusing operation.


We first use the CPU-Z to check the CRD2's hardware configuration, RK3288 quad-core CPU, clocked at 1.8GHz, Mali T764 core GPU, 2G memory, 16G flash memory, this configuration is relatively powerful in the current calculation .



Ann Bunny ran out of the high score of 39,810. Considering the current mainstream 4-core player, the security Bunny ran basically all around 20,000 points, while CRD2 nearly doubled the score, enough to witness its powerful hardware. Configuration.


In the score rankings, CRD2 scores also rushed to the upper reaches of the level, the millet 3 has always been known to run points behind them, the top few are the latest flagship models of major brands, and mobile phones Run points are also better than projections.


Next we use Vellamo to test the overall performance of CRD2's browser. After several tests, CRD2 has achieved outstanding results in various test points, which shows the performance and stability of its browser, including the network, scripting , rendering, and user experience are all at a relatively high level.


The score of the three tests.






Nenamark2 hardware acceleration benchmark results, 57.7fps, this score can be considered very high.

The cloud interface CRD2's UI interface adopts the WIN8 tile style. The home page is VST all-aggregated related content. The six major sections are "Internet TV", "Network Video", "Best Recommended", "System Application", "Game Center" and "My Settings". Some of the menus are slightly duplicated, just a shortcut to VST's all-aggregated program submenu. The main interface does not support user-defined settings. It makes me feel a little regret. The setup is divided into four parts: "network Bluetooth", "advanced settings", "display and audio-visual equipment" and "about equipment".


Network Bluetooth is mainly related to some network settings, WIFI, wired networks, portable hotspots, and Bluetooth.


If you only have a wired network in your home and you don't have a wireless router, then CRD2's portable hotspot function is certainly useful. After connecting through a wired network, you can turn on a portable hotspot, and then your phone or tablet can wirelessly access its hotspot to access the Internet. Now.


CRD2 built-in Bluetooth 4.0 module, you can easily access a variety of Bluetooth devices, even when out on the go, carry a portable Bluetooth speaker, can also bring a good sound effect. However, compared to wired audio output, Bluetooth output will have a slight delay, but basically can be ignored.


In the advanced settings, some languages, input methods, and date settings of the CRD2 are included. If you want to connect to a PC, you need to turn on USB debugging here.


Sounds and displays include sound, brightness, and font adjustments, as well as automatic keystone adjustments. Auto keystone correction can eliminate the irregularity of the image formed due to the incorrect projection angle, but only has the most basic trapezoidal correction function, ie, the vertical trapezoidal correction function does not support the horizontal trapezoidal correction, and the angle must reach a certain degree. Automatic trapezoidal correction, so the slight deformation is basically not corrected. In addition to the trapezoidal correction, the loss of image quality comes with it. Therefore, if conditions permit, try to use positive projection to obtain the best viewing effect.


In About This Machine, there are some accounts, applications, and factory-related settings.


There is no design application channel in the settings, so we need to enter from all applications of the "system application", where you can find all the applications that you installed, enter the Android native settings also need to enter from here.

We know that as the projection distance increases, the brightness will gradually decay, and the picture quality will become worse and worse. So the brightness of the machine and the projected size have a very big relationship with the display effect. From the parameter testing chapter, we measured the ANSI brightness of cloud network line CRD2 as 360 lumens and the ANSI contrast ratio as 53:1. What will happen to the display effect? ​​Let us take a look. (Note: Due to factors such as shooting environment and shooting level, the actual display effect is slightly different from the screen shot.)
Cloud network line CRD2 is a short-focus model, can project a 100-inch screen in about 2.5 meters. After testing, the optimal projection size of CRD2 is about 80-120, and there is a noticeable drop in the quality beyond 120 pictures. . The ANSI contrast ratio of CRD2 is 53:1. It can be seen from the following gray-scale graph that CRD2 can vaguely identify 4 levels and it performs fairly well.


The following screen shots were taken in a completely black environment and only the original film was compressed without any beautification. The shooting size is about 80 inches and the curtain is white glass fiber. The overall display effect of the picture is still very good, and the color reproduction is more real and very beautiful.
















Cloud network as a home entertainment portable micro-projection, we do not need to care too much about its performance during the day, I am very responsible to tell you, the effect is certainly not good, and all non-business projectors currently on the market The daytime projections are not good unless you request very low. Not to mention projectors with thousands of dollars, even if the projection equipment of the hundreds of thousands of Wanda Studios can only get good results in a completely dark environment. When they turn on the lights, the quality immediately goes down. So, if you play with projections, you'll be comfortable using it in the evening. Others, don't think too much.




Cloud Network CRD2 uses an Android 4.4 system, and can freely install all kinds of live and on-demand video applications. In order to facilitate user use, VST all-in-one, PPTV, pudding, kaleidoscope, and other online video software are initially built. VST all polymerization as the main play software, occupying two pages. It includes online live broadcasting and on-demand broadcasting.

The online live broadcasting may be due to the impact of the early stage of broadcasting, the buffer speed is not very satisfactory, and the live broadcast quality is also very general, mostly in the standard definition format, and the HD image quality is relatively small.




The on-demand performance is more satisfying. Not only is there a lot of film and television resources, but also the update speed is relatively fast. Many movie theaters can be found quickly here, but most of them are guns, HD version is also more than the general The video software updates faster. In terms of image quality and buffering, it is a relatively good software.

In addition to its own built-in software, we can also install other APPs in many ways. Here we still strongly recommend HDP live streaming. Not only HD channels, but also soft and hard solutions, fast changeovers , boot from the start, programs look back and other kinds of intimate functions, it can be said in the free live APP in the absolute count NO.1.

Cloud Network CRD2 adopts RK3288 quad-core CPU, clocked at 1.8GHz, and uses Mali T764 core GPU, 2G memory, and 16G flash memory for graphics processors. These hardware data provide reliable local HD playback. Protection. We first used the security Bunny video test software to test it, and the test results made me very satisfied. The full screen was green, and all the tested video and audio formats passed. Only 320 points is what the situation is, is it difficult to get into security rabbits scared by CRD2?



Watching CRD2's local video can be accessed through the built-in Explorer. It clearly shows the actual conditions of various external devices. However, there are still some problems with the software. That is if your hard disk has partitions, the system will only display one. The drive letter, but it contains some of the contents of other partitions, this problem is often seen in some TV boxes, not a big problem, the system optimization is easily solved.

At present, 4K is already fast becoming a mainstream trend. Display and playback devices have matured. The only bottleneck is the film source problem. Once this problem is solved, 4K will rapidly spread. The measured CRD2 can play most of the 4K videos normally. However, the audio and video are not synchronized due to high bit rate.




H.265 is an upgraded version of the current H.264 standard. Its advantages are obvious. This new technology will undoubtedly bring about a brand new multimedia revolution. The same network environment can transmit clearer high-definition video, but It also has higher requirements for the hardware of the device. Now the new mainstream TV boxes are also selling H.265 encoding. After testing, CRD2 can easily play H.265 encoded video.


H.265 supports 4K (40962160) and 8K (81924320) Ultra HD (UHD) content, which makes it undoubtedly the most important channel for 4K Ultra HD. In the next few years, 4K will be popularized for TVs, PCs and tablet PCs, which will make H.265 a general trend with the popularity of 4K. Cloud network CRD2 as a H.265 decoding micro-projection products, will be strongly sought after by HD enthusiasts.


Cloud Network CRD2 supports 3D video playback. With active 3D glasses, you can experience 3D blockbusters at home. However, CRD2 does not support the automatic recognition function, so it needs to be manually adjusted for 3D videos in the left and right formats. The independent 3D button on the remote control makes the 3D settings very simple. Press it lightly to complete the 3D display.


The screen display is clear and natural, there is no flickering phenomenon. When watching some 3D demos, the presence is very strong, and the effect of the screen is very obvious.


After testing, several 3D samples played normally, including left and right, up and down a variety of formats, 3D effects are also very realistic, external subtitle files need special 3D subtitles to display properly. With the 200-inch 3D projection display, it is truly at home to experience the effects of a small 3D cinema.


Cloud network CRD2 can play 4K and H2.65 encoded ultra-high definition video perfectly. Then those 1080P and below videos are worth mentioning. After many sample tests, the current mainstream audio and video formats CRD2 can Perfect playback, including AC3 and DTS format audio that many machines cannot play. However, this is not to say that the CRD2's native playback function is perfect. Because the firmware is not perfect, CRD2 can't play ISO files at present, and it can't identify the Blu-ray original disc, but the official has responded that the recently updated firmware can recognize the playback. Blu-ray ISO and Blu-ray original files too. At present, it does not mean that it cannot be played. We can use third-party software, such as XBMC. In this case, the Blu-ray ISO format can be played normally. However, the original file cannot be played directly, or the folder must be opened. Play.


For ISO format files, we can set XBMC as the default player, which can also achieve the effect of point-to-point broadcast.


Blu-ray ISO can now be watched normally, and subtitles and audio tracks can be selected.


Although it is the use of third-party playback software, but there is no CRD2 powerful hardware protection, XBMC is a clever woman can't be without meter!

The CRD2 system's built-in video player can also select subtitles and audio tracks, but it is not as clear on the selection, and further optimization is still required.


CRD2 supports the network neighborhood function. It also clicks My Network Places in the resource manager interface. The system will automatically search for the storage settings in the same local area network. After the search is complete, the system can play and share. The CRD2 uses a wired Gigabit network, and local sharing can also easily play 4K HD movies.


As a home entertainment device, just watching a movie and TV seems to have failed to satisfy the user's taste, so cloud network line CRD2 also joined the game area, open the game hall, we can find in it a lot of childhood fascinated Games, whether it is arcade games or simulator games, there is always one you like very much. Looking at the familiar icons, the heart is really a little excited! The King of Fighters, Kuaisansan, and the Snow Mountain brothers, these are all skipping lessons to play when I go to school. (Saying more, exposed the essence of my bad student that year.)


There are really a variety of games on the platform. The number is very large. It is really an installation that cannot be stopped. Fortunately, the CRD2 has 16G of storage space, and it is not afraid to install more. Not only support the handle control, but also can download the software to control with the mobile phone.


In the year of the PS2, the most popular game is "The Warriors of the Serpent," and this game requires a handle to play. There are just a few wireless handles on hand. Tested on the CRD2, you can basically use it normally.


The following game, it is estimated that friends in the 7th, 8th, and 90s will not be unfamiliar with it, one of the hottest arcade games of the year, "King of Fighters 97", the pinnacle of arcade fighting games.


"Snow Mountain Brothers" is a very fun arcade casual game. I used to play this very much and I can always push it to the end.
