Subject:
TWP/TSI/C2 - Camera failure
DataStreams:twptsiskyimageC2.a1, twptsicldmaskC2.a1, twptsiC2.00, twptsiskycoverC2.b1,
twptsimovieC2.a1
Description:
The operation of the camera was itermittant. It produced very poor "hazy" images, blank 
white images, or no images when the camera failed to respond. Several attempts were made to 
correct the problem, involving checking the power and ethernet connections and wire and 
cleaning the lens and filter. The camera was replaced by a spare.
Suggestions:
