Figure Lengend Snippet: Experimental set-up with the 3D near-infrared video tracking system. ( A ) Original view from behind the cameras' position. ( B ) Sketch of the set-up showing the different elements. The net sample (N) was placed at two thirds of the length of the tunnel away from the release cage (R), dividing the tunnel into a larger (A) and a smaller (B) section. The release cage (R) was attached at the end of the longer section of the tunnel (T), while a blood feeding unit (F) was placed in contact with a mesh closing the end of the shorter section of the tunnel. The two cameras (C) were pointing towards the tracking area, while four NIR lamps (L) illuminated the tunnel. The cameras were connected to a desktop computer and screen (D) placed near the experimental cage, allowing for controlling the system during the experiments. The experimenter (E) sat in front of the computer next to the blood feeding unit.
Article Snippet: The software was used in combination with two acA2040-90umNIR USB 3 digital cameras (Basler AG, Ahrensburg, Germany), one near-infrared (NIR) light emitting diode (LED) lamp (Raytec pulsestar illuminators PSTR-I96-HV, Raytec Ltd, Ashington, United Kingdom) controlled by a controller (Raytec pulsestar illuminators PSTR-PSU-4CHNL-HV, Ashington, UK), and three custom-made NIR LED lamps (Ingenieurbüro Warnke GmbH, Wietzendorf, Germany).
