Overview
ST-1804R is 4 channel active video receiver. It adopts the Cat5/5e/6 cable as the transmission medium,
being able to receive single channel color or B/W PAL、NTSC、SECAM video format in real time. In actual project,
it can work with SECTEC passive video transmitter or SECTEC passive transmitter as a pair. ST-1804 features
long distance, excellent transmitting image and anti-interference. It’s widely used in the projects like security monitoring project.
ST-1804R has 4 range distance at option. With adjusting switches we can set the brightness and sharpness of the camera video.
