Several different cameras have been used over the past few years.
The first was a Watec-902H black and white video camera with a 1/2 inch CCD. With a Fujinon-TV 25 mm F/0.85 lens attached, it had a FOV of 11 x 14 degrees. This system recorded anywhere from 30 to 70 meteors per cloudless night. The chip was quite sensitive but had a lot of graininess.

Tests were done with a Mintron 12V1C camera with a 1/2 inch SONY Super HAD CCD chip. Although initial results with the 12V1C are much more aesthetically pleasing than the Watec-902H, given the huge dynamic range and low noise of the camera, it is not significantly more sensitive. In February 2004 the Super HAD camera was replaced with a slightly more sensitive Mintron 12V1C camera utilising a 1/2 inch SONY EXview chip. 

Cameras at Mudgee have these FOV:
North facing 6mm lens = 55 x 40 degrees
Overhead 3.8mm lens = 90 x 65 degrees

A 3rd camera was added to the Mudgee site in 2017. Set up next to an old caravan with a control room inside.

Doing a rough calculation, averaging 25-30 meteors per camera per night, I've seen well over 300,000 meteors. Rob has seen probably 3 or 4 times that many.
