Can the range be extended? Can passive and active devices be combined?
For less than 750 feet (230 meters), you can use passive devices on each end. For runs up to 3,000 feet (915 meters), then use a passive transmitter behind the camera with an active receiver. For up to 6,000 feet (1,830 meters), use active devices on both ends. Vigitron does not recommend cascading twisted pair transceivers as repeaters to further extend the distance.
