A notable site is Glen Ridge Farm, Lexington, where a prominent breeder is using the cameras in nine stalls and reviewing images at night from the comfort of their home on a hard-wired system with a nine-channel colour duplex multiplexer.

"The pricing of the Rainbow unit is competitive and this has meant that we can suggest multiple-camera solutions to clients without them baulking at the cost" says Dough Hocker of Barney Miller's "The Rainbow bullet unit we're using has a 70° field of view which has proved suitable for this unusual environment, capturing everything that happens in the stalls. The camera can operate at F2.0 so varied lighting conditions don't pose a problem"

While some breeders choose simply to monitor the images others record the footage. The Vinery, a major stable in Fayette County, has connected the cameras to a Panasonic time & date generator and one of Panasonic's digital video recorders.
