Dahua Head mounted TV is a kind of head mounted display device developed by Heijing, which is easy to associate with VR glasses. But in fact, Dahua Head mounted TV is not VR glasses. It is indeed a head mounted TV, which has many similarities with the first generation Heijing H1, but also has many differences. It removes some functions of Heijing H1 and adds some VR experience content, It can be said that the high-end and low-end can not be said with Hijing, because their functions are similar but different. Of course, the author has not experienced the second generation product of Hijing H2. Here we will talk about the similarities and differences between Hijing H1 and Hijing H2.
The traditional VR shape adopted by Dahua Head mounted TV is a circle larger than that of Hi Mirror H1, but the eyepiece vision is also wider. Compared with Hi Mirror, Da Hua's head mounted TV model is very simple, and there are not too many fancy designs. The fixed position of the three sides of the head wear and the pupillary distance adjustment knob on the top, and there is basically no redundant design and shape. The pupil eyepiece of Dahua's head mounted TV is still round. Compared with the oval design of Hei Jing H2, it seems that Hei Jing H2 is more reasonable. After all, the human eye itself is oval, which is a better design in line with human eye engineering. Fortunately, the vision effect of Dahua's head mounted TV is better than that of Hei Jing H1. It is a pity that Dahua TV has no myopia adjustment function, and myopic users can only watch with glasses or wear contact lenses. A human body sensor is set in the center of the pupil of Dahua Headworn TV. When wearing it, the screen will light up automatically. When removing the Dahua Headworn TV, the 4K screen inside will automatically close, effectively reducing the waste of power. The protective pad is designed around the eye mask, which is comfortable to wear.
I remember that during the previous experience of Hi Mirror H1, the eyepiece lenses were particularly prone to fogging, especially in winter, Hi Mirror H1 had to wipe the eyepiece lenses within a few minutes, but this time the big picture wore a TV and felt that the problem had been effectively solved. Due to the hot weather, I could only try to set the air adjustment to 16 degrees to test whether it would be fogged. At present, no fogging was found. Maybe after the improvement of the first generation, Dahua Headworn TV has become more and more perfect in the subsequent products. Dahua Head mounted TV also has a host, a handle based host based on Android system, which can be easily operated blindly when wearing Dahua Head mounted TV. The host size is moderate. The operation is sensitive, but the heat is a little high during operation.
In terms of interface, Dahua head mounted TV host can expand the memory card, external USB data content, including U disk and mobile hard disk, and play a large number of local movies through external hard disk. The charging transmission interface of Dahua Headworn TV adopts typ-c interface, and the charging transmission data can be plugged in blindly.
The Dahua headset TV is connected to the host through HDMI, which is basically the same as the previous generation of Hikvision H1, but it is worth mentioning that, like H1, the HDMI cable is fixedly connected to the headset display and cannot be replaced. If the HDMI cable is broken, it will be troublesome.
Dahua Head mounted TV is relatively simple to wear. It is fixed by three fixed ends with a fixing belt. The size of the headband is adjustable. Easy to wear and adjust, good firmness. The weight is a little heavy. It's OK for men to wear it, but it's a little heavy for women. It's better to look up when wearing, and can bear some weight.
The logo of the front large picture head mounted TV is 1:1, which mainly means to show the real picture restoration. What kind of experience is the big picture head mounted TV? In fact, the Dahua Head mounted TV is a flat screen display device just like the Heijing H1, which mimics the effect of the cinema. Here I will show you the previous experience picture.
The main pictures are similar to this experience with black edge effect, just like watching movies in the cinema. The whole picture is very grand, which can be said to be the ultimate effect of vision. It is also the maximum visual effect that the eye can accommodate. It is equivalent to the middle row of the cinema, just enough to see all the pictures.
There are residual power displays on the upper right side of Dahua's head mounted TV host and in the changing face, so it is easy to watch movies for a day. As a mobile movie device, you can see where you go.
The human induction recognition of the big picture head mounted TV can see that the screen in the eyepiece will only be displayed when the human body blocks the sensor.
The big advantage of Dahua Head mounted TV is that the effect of watching 3D movies is better than that of cinemas. Many people may not know that most of the 3D technology in general cinemas is polarized 3D. After wearing glasses, the brightness is significantly reduced. The 3D mode of Dahua Head mounted TV is active shutter, and the screen is switched through the setting key on the mainframe of Dahua Head mounted TV, You can watch 3D movies in left and right formats The effect is very obvious, absolutely better than that of the cinema.
Dahua HDTV can also watch online 3D movies directly, but 3D broadcasting does not seem to be well supported and may need to be improved later. The software line of Dahua HDTV itself has 3D resources. Although the online resources are known as 1080P, the 1080P bit rate has been compressed, and the image quality is still far inferior to that of local 1080P movies with 10G or more, In pursuit of picture quality, it's better to make a 1080P movie.
Many people also want to know whether Dahua will feel dizzy after wearing the TV belt for a long time. In actual experience, there is no feeling of dizziness. Only the 3D mode may be a little dizzy after watching for a long time.
The content of Dahua Head mounted TV is very rich, and there are many free movies, especially VR resources. With its own gyroscope, although it does not display images on the full screen like VR glasses, it can also experience the effect of VR glasses, which is half the effect of VR experience. I believe that VR glasses will be displayed behind Hi Glass to match these resources.
The online resource effect of Dahua HDTV itself is relatively good. At the same time, Dahua HDTV has its own 4K screen, and the realistic effect is exquisite. Although the 4K screen is mentioned, from my personal point of view, Dahua HDTV should be composed of two 1080P screens, that is, the single eye 1080P. Compared with those traditional 2K all-in-one machines, the effect of Dahua HDTV is really better. The reason for the single eye 1080P is that most movie originals on the market are 1080p, and the size is more than 20G. It is conceivable how big 4K is. Although many online websites claim that 4K is playing online, it is actually just fake 4K. 1080P online play has not yet been fully popularized. What we see is that 1080P online play is compressed.
The VR resources of Dahua Head mounted TV can be experienced, but they are not real VR, but you can understand what VR experience is like. There are still many VR resources for Dahua HDTV, but there are not many complete films, because there are not many films supporting VR at present.
What kind of experience is VR? The big picture head mounted TV gives a better interpretation. It can be adjusted to the VR mode or the standard mode. VRX displays local pictures, and can freely turn up, down, left and right to see the surrounding pictures. The standard mode shows the panorama, just like the panorama mode of our mobile phones, a surrounding picture is displayed as a plane.
I also tried to connect the computer and the TV box with Dahua Head mounted TV, but unfortunately it was not supported very well. When connecting the computer, there was a picture, but it was not fully displayed. It was not a complete computer picture. The screen is not displayed directly when the Android box is connected. Unlike Hijing H1, it can support external boxes and computers very well.
Conclusion: From my understanding, no matter Hi Mirror or Dahua Head mounted TV, they have not made traditional VR glasses. The main reason is that there are not many VR glasses resources, and the technology is immature. Although the immersion is strong, it is just a fresh experience. Due to the lack of content and immature technology, I am tired after watching it for a while, However, Hi Mirror and Da Hua head mounted TV is just like a personal TV. It is a head mounted display that restores the feeling of watching TV and movies, so it can be understood as a personal small TV. It is more practical than VR, and the 3D effect is outstanding. It can be said that it is a good 3D movie player. This is also the main difference from VR. If you want to have a personal cinema and watch movies and TV at ordinary times, then big picture head mounted TV is a good choice. If you want to experience immersive virtual reality, VR glasses are better.
