A few months ago I fly a mission with a Tau 2 640 infra red camera. All the info is here. The first trial prove that the equipment can indeed operate in night condition and we learn how to take off and land in that condition. Unfortunately during the first few flight we did not capture clear video that show the existent of our target, the small size marque monkey. This is mainly due to the inconsistent radio collar signal we received ,so we may have plan the wrong flight path.
This time, with a more organised planning, sufficient ground survey to confirm the movement of the two monkey that fitted with radio collar, we know where our target was and plan the flight accordingly. With the same set up and same flight altitude, this time we do successfully record them which show up as bright white spot in the video.
Flying at 100 meter, the monkey only show up as a few pixel through the camera sensor. So we are not hoping to see the animal outline through the video. As there are no bigger size animal stay on top of tree at that area, those white spots found around the tree area are pretty much confirm that is the marque monkey. More detail analysis will require to make accurate survey but we have demonstrate that it is viable with our low cost UAV.
I post this video for those who may be interest to use this camera for their research work as a video out put reference.
