Active or near infra-red (NIR) illumination is energy which is invisible to the human eye but can be seen by a high quality true day/night camera (IR cut filter removed). The energy from IR illuminators resides just outside the visible red section of the electromagnetic spectrum, above 700nm and below 1000nm.
IR illumination is an ideal source of illumination for security cameras for the following reasons.

• It is invisible to the human eye but visible to black/white and true day/night cameras.
• Avoids the problem of light pollution.
• Longer range than visible light

All Iluminar illuminators provide superior IR lighting for video surveillance systems. They are available with a range of angles to cover different distances and scenes.

Supplied with an IP67 rating, they are vandal proof and can be used indoors and outdoors. The anodized aluminum housing provides protection from the harshest weather conditions.

There are many advantages of using separate, professional illuminators versus built-in camera infrared illuminators

• Longer life on the LED's
• No hot spots
• Wider angles
• Longer range
• Avoids attracting insects to obscure camera view
