Notes: - The appropriate focal length of the camera lens needs to be tested by yourself. Factors such as camera distance and experimental box size will affect the choice of focal length. - It is recommended to let the camera manufacturer provide different software identifiers (different names) for each camera to facilitate differentiation. - Sliders are not that necessary, as the field of view can be adjusted by focal length. However, PTZ is necessary because it is needed to adjust the camera angle. - Red light illumination LEDs are placed at the 6 corners of the bracket for even illumination. Otherwise, a single light source can easily cause image shadows, leading to reduced accuracy in subsequent animal analysis. The light intensity is high, so part of it needs to be blocked to achieve a final illumination of about 20 lux. - Do not connect cameras directly to the computer's USB port, as the motherboard's USB bandwidth is severely limited and cannot connect multiple cameras simultaneously. Please use a professional-grade PCIE-USB expansion card (U3412U)!!
