ZWD-1222 and ZWD-2422 are two advanced wireless audio and video transmission solutions developed by Taiwan’s Zhaohe Electronics Co., Ltd. (ZINWELL) using Israel's WHDI technology. Introduced in 2011, these products have revolutionized the way high-definition content is transmitted without the need for physical cables. With their powerful technology core and strong secondary development capabilities, they have filled a critical gap in the wireless HD video transmission market.
The ZWD-1222 model is designed for home and office environments where users want to eliminate the hassle of tangled cables. It supports lossless 1080P HD transmission over a distance of 15–30 meters with some wall-penetrating ability. This makes it ideal for use with HD projectors, home theaters, and conference rooms. The product allows for plug-and-play functionality, automatic frequency switching, and zero interference, making it perfect for entertainment, presentations, and more.
One of the standout features of the ZWD-1222 is its multi-task mode, which enables users to run multiple applications simultaneously. For example, while one person is watching a movie on a large screen, another can be working on a computer without any disruption. This feature is especially useful in family living rooms or corporate settings where multiple tasks are happening at once.
Another great application is the wireless mouse and keyboard program. With ZWD-1222, you can control your TV or projector from a distance, eliminating the need to constantly move around the room. This adds a level of convenience that traditional wired setups simply cannot match.
For multimedia enthusiasts, ZWD-1222 also supports Blu-ray players, HD players, and even gaming consoles like PS3. This means you can enjoy full HD movies, games, and videos wirelessly without compromising on quality.
ZWD-2422, on the other hand, offers enhanced performance compared to ZWD-1222. It has a longer transmission range—up to 10–30 meters—and can connect up to two HD devices simultaneously. It also supports output to two separate displays, making it ideal for multi-room setups. Whether you're watching a movie in the living room or presenting in a conference room, ZWD-2422 ensures smooth, uninterrupted HD transmission.
A common use case for ZWD-2422 is in multi-room homes where multiple TVs and playback devices are used. By connecting two devices to the transmitter and sending the signal to two different displays, users can enjoy synchronized HD content across different areas of the house. This is especially useful when you want to watch different content in different rooms without the need for extra wiring.
Additionally, ZWD-2422 includes an infrared coupling remote enhancer, which solves the problem of controlling devices in different rooms. This makes it easy to manage your entire setup from one place, improving usability and convenience.
When comparing ZWD-1222 and ZWD-2422 to similar products on the market, the difference becomes clear. Most wireless solutions use the 802.11N standard, which limits bandwidth and results in compressed video and lower quality. In contrast, WHDI technology provides a 3Gb/s bandwidth, allowing for lossless transmission of HD video and audio, including Blu-ray content.
In terms of resolution, most wireless devices only support 720p, while WHDI-powered models like ZWD-1222 and ZWD-2422 fully support 1080p at 60Hz. They also support 7.1-channel audio with a sampling rate of up to 24-bit/192kHz, delivering an immersive audio experience.
Anti-jamming is another key advantage. Unlike standard Wi-Fi devices that operate on crowded frequencies, WHDI uses the 4.6G–5G band and features intelligent frequency modulation to avoid interference. This ensures a stable and reliable connection, even in busy environments.
Finally, the low latency of WHDI technology sets it apart. Since no compression is needed, there’s no delay in video transmission. This is crucial for real-time applications like gaming or live presentations.
Overall, ZWD-1222 and ZWD-2422 offer cutting-edge wireless HD solutions that cater to both home and professional users. Whether you're looking to simplify your home entertainment system or upgrade your conference room setup, these products provide a seamless, high-quality experience.
