It appears that the MarshallingCam has finally died - not comprehensively, but enough so that its wireless connectivity is no longer operational. It seems unreasonable to lay 150m of CAT5 to connect it, so it is useless for my requirements.
Since I put the donation button on my sites about two months ago, 11 people have kindly donated and I will use their donations for a new, more reliable wireless camera to use as a MarshallingCam and/or remote cameras.
