Hi Folks,
Thanks for all the nice comments. To answer the questions,
Yes I bought it from Amazon, it was the same price as from the manufacturer but I know and like the Amazon return policy.
Those speed bumps are still a contentious issue, sadly the vote to install them passed which just goes to show that democracy is the tyranny of the majority over the minority.
The camera was inside its waterproof box and what you heard was the audio from the internal mic. In order to maintain the seal of the housing you cannot connect an external mic when it is the box. I shall have to record a conversation with it in the box to see how it records voices. I have used it as a car dash cam with it just in the frame and the internal mic picks up every sound (which is mainly a long litany of me offering helpful suggestions to my fellow motorists).
With regard to the quality of the replay, I can tell you that the raw data is crystal clear. when I download to my PC and play in full screen the results are what you would expect at 1080. However here in the boonies my internet is not the fastest and I too noticed a degradation on the video. In fact to even get it to play I had to set the quality to 480
I am sure that what you saw was not a result of the camera.
All the best
