The VARIO Daytime Set-up Tool (DST) is designed to help installers position and align their surveillance lighting during daylight hours, when night-time set-up is not possible. It is particularly useful for Infra-Red lighting which is invisible to the human eye. The DST fixes directly to the extrusion of any VARIO/ other Raytec illuminator and provides a viewing piece which allows you to see the exact target at which the light is pointed; you can then adjust the illuminator accordingly
