My secondly ordered DVR arrived at last.
Made a short test vid in dim light conditions, that is why the footage is B/W.
I shall try to find a day when the park lot is mostly empty and there is no traffic.
Then I can make a longer trip inside it
For now this is what the DVR saw:
Took the M150 prototype v2 for the first park ride this afternoon.
The picture quality is not so good due to YT conversion but the video signal clarity can be seen well.
As soon as the HD recording capable third prototype is ready, the video quality will be much better.
