The Pelco IR850S-65/IR940S-30 Series of infrared illuminators is designed for video surveillance applications. IR850S-65/IR940S-30 Illuminators are the perfect overall lighting solution, combining platinum LED optic technology with unique product features such as remote control and LED status feedback system, providing an energy-efficient and controlled lighting solution. The IR850S-65/IR940S-30 Series features a unique Interchangeable Diffuser System (IDS) which allows users to quickly and easily change the angle of illumination on-site to match the required field of view. The IDS uses the latest holographic light-diffusing technology which produces a targeted and accurate beam pattern directing light to where it is needed most. This technique allows greater illumination distances and prevents overexposure of foreground objects, delivering an evenly illuminated and smoother video surveillance image.
