SF1534 is a wireless video transmission module based on the globally open 2.4G ISM band. SF1534 adopts standard CVBS signal input, supports two systems of NTSC and PAL, and sends it to mobile client for wireless display after processing by SF1534.
SF1534 is a wireless video transmission module based on the globally open 2.4G ISM band. SF1534 adopts standard CVBS signal input, supports two systems of NTSC and PAL, and sends it to mobile client for wireless display after processing by SF1534.
The main features of the product scheme are: adopt the mature wireless standard 802.11BGN, strong anti-interference, large bandwidth and strong equipment compatibility. The supporting IOS or Android platform client software developed by Sunflower Sunflower can easily operate the module on mobile devices.
The SF1534 can be battery powered and has a wide voltage input range. Provide a wealth of control interfaces: UART, high precision PWM, NEC format infrared remote control output, so SF1534 can communicate with its external devices in various ways. The small size of the module can be easily implanted into the main application system.
SF1534 is widely used. Because it uses CVBS video signal input and can be widely compatible with various video output devices, it can be used in the field of remote control cameras (gropo2 HD), TV signals are forwarded to the Internet (set-top box), aerial photography, etc.

Short description:
The self-developed wifi video
module uses advanced image compression technology to truly realize
point-to-point two-way data transmission through wireless WIFi, point-to-point
sending data, and images to any display terminal (Android, iPhone IOS, etc.).
The software vsender installed by the smartphone completes the processing of
application functions such as video display, storage of pictures and videos,
and sending instructions. At the same time, according to customer requirements,
the use of wifi video modules can be developed in depth.
