The so-called home projection is mainly a sub category compared to portable projection, business projection, and educational projection. It refers to the main usage scenario being at home, highlighting the user demand for home audio and video entertainment. So the essential function of home projection emphasizes “home entertainment”, rather than the PPT display for business/educational projection or the built-in battery for portable projection

Side cast

With the side projection function, there is no need for lifting or forward projection to ensure a flat and straight image. To determine whether the projector has side projection function, check if it supports “four corner trapezoidal correction”. Based on actual experience, the priority of the side projection function is: automatic+manual trapezoidal correction combined>pure manual trapezoidal correction>pure automatic trapezoidal correction, because manual trapezoidal correction is more accurate. In addition, the angle of side projection is also important. Currently, the correction angle for LED micro projection is ± 45 °, while traditional bulb machines have 15 ° and 20 °. The larger the side projection angle, the greater the freedom of placement. At present, the vast majority of CAIWEI’s intelligent projection products support ± 45 ° four angle trapezoid correction and automatic trapezoid correction

Support hard decoding function

Hard decoding technology is four times faster than soft decoding technology, allowing for seamless viewing of ultra clear 4K movies online. In the coming years, hard decoding technology for home film and television projectors will become mainstream.

Hi-fi stereo

Home projectors have increasingly high requirements for sound technology, and the dual channel Bluetooth sound system can no longer meet the needs of users. Surround stereo sound is the future development direction

MEMC and HDR10

Many people focus on core parameters such as resolution, lumens, and decoding when choosing a projector, but overlook the importance of MEMC motion compensation and HDR10, especially in machines with comparable hardware configurations such as CPU and memory. For home users, the types of movie watching are relatively diverse, so motion compensation can adapt well to this demand, ensuring smooth movie watching, while HDR10 can display more details in the picture. CAIWEI A9R and other products support MEMC dynamic compensation and HDR10.

USB 3.0 interface and 5G Wi Fi

Both of these are related to ‘speed’. The USB 3.0 interface is mainly used to read external storage media such as portable hard drives and USB flash drives. USB 3.0 is much faster than USB 2.0 in terms of transmission speed. 5G band Wi Fi is superior to traditional 2.4GHz Wi Fi in terms of network speed, but this not only requires support from projectors, but also from routers
