This camera is from the new generation of that supplied to BBC Springwatch 2011 team for their Little Owl nest box footage. Camera is New Generation 1/3" HIGH DEFINITION camera wuth audio and infra red and fitted with a HD LENS GIVING 30% GREATER COLOUR IMAGES AND SHARPER CLOUR IMAGES, for use in nest boxes and feeders. Uses the new SONY chipset for enhanced colour definition and better infra red night vision The camera is fitted with a sensor to cut out the infra red lighting during the day. The colour images are crisp and clear and are not faded as would be the case if the infra red lighting was permanently switched on. For best picture field of view, the camera is focused to 100mm from lens and gives a spread of 60 degrees. This allows for the birds to build up their nest and the camera to remain in focus. Fine adjustment to the focus can be done by releasing the locking screw and turning the lens clockwise/anti-clockwise. Picture quality can be further enhanced by fitting the optional Background Lighting Module, a sensor controlled light source to illuminate the inside of the nest box and not rely on windows fitted on the sides which in turn depend on the outside weather/sunlight to give colour images. Dull weather means poor quality pictures, better light means better definition. The difference in picture quality is considerable with having this feature on board. Supplied with 20 metres of cable, 12 volt power supply unit and scart adaptor for TV use and FREE predator guard kit For PC/Laptop/Mac use, you will need a video to usb adaptor.
