Generally, we advise that the illuminators be mounted away from cameras such that the illuminator’s light does not shine into the camera’s lens. Additional spacing between the camera and the illuminator can be beneficial in areas with high insect populations. In cases where the camera and illuminator must be co-located (such as on pan tilt units), we try to position the illuminator forward far enough to keep the illuminator’s widest angle from hitting the front camera enclosure opening. Adding a “hood” or shield can help prevent light from hitting the camera’s lens if needed, but that is all it does – it will not make the light beam pattern any smaller.
