Using internal infrared illumination<\/h3>\n

The EYE-02 and EyeSee security cameras are equipped with internal infrared (IR) illumination. This internal illumination is suitable for
\nuse under three conditions:<\/p>\n

    \n
  1. The distance from the monitored object is less than 6 m. An example below shows difference between a room illuminated by daylight and IR light in a room of such\u00a0dimensions.\n

  2. There are no objects in front of the camera zone emitting IR light. If there is an object directly in front of the camera zone emitting IR light, this object reflects emitted IR light back to\u00a0the lens. The object causing the reflection is then very bright and the picture quality is reduced.\n
  3. There is no plastic or glass (window, outdoor housing, etc.) placed between the camera and the monitored object. Below, you can see a picture taken by the camera using internal IR illumination while a plastic\/glass was placed in front of the lens. An outdoor camera cover with front glass was used in this case.

    If you want to use EYE-02 or Eyesee camera with infrared illumination without being restricted by the above-mentioned conditions, you need to use an external IR illumination as described below.<\/p>\n

    Using external infrared illumination<\/h3>\n

    You can use an external IR lamp instead of the one that is built-in. You can see an example of a lamp and its installation on the pictures below.<\/p>\n

    We suggest switching off the internal IR illumination when an external IR lamp is used. Connect to the camera in www.jablotool.com<\/a> and select Settings (Advanced)<\/strong> > Advanced video settings<\/strong><\/p>\n

    When you use external IR illumination, you obtain a brighter picture in comparison to the picture taken with internal IR illumination. Please compare the two pictures below.<\/p>\n

    Pictures taken with external IR illumination have bigger contrast and moving persons are not blurred. Also, viewing distance of the camera at night is larger. Generally, the more external IR lamps you use, the better quality of the pictures. External illumination is very convenient for outdoor use of camera.<\/p>\n

    Please be aware of four rules while using an external illumination:<\/p>\n
