Es gibt eine ganz berühmte Schleiereulen-Familie in den USA, die in einer Eulenbox rund um die Uhr beobachtet werden kann (alle Junge sind jetzt aber schon ausgeflogen). Der Mann, ein älter Herr, hat dabei eine Kamera von Logitech und eine von Agama. Hier ein paar FAQ's die er zur Kameratechnik angiebt:
Why is the video sometimes in color and sometime black and white?
The box has two cameras; one is used during the daylight hours. At night, when no natural light is available, we switch to an infrared camera which makes a black-and-white image. There is also a third camera that shows up only on the Royals living room television.
What kind of cameras and lighting are used?
The cameras are Logitech Orbit AF (daytime) and Agama V-1325 R (infrared, nighttime). There are 4 infrared (IR) LEDs on the camera that are invisible to owls and humans, but allow the camera to pick up an image we can see at night. There is also ambient light from the neighborhood that comes into the box at night.
Is this camera hardwired, battery operated, or solar powered?
It’s hardwired.
Can the night cam zoom in?
No, only the daytime camera has zoom and is height-adjustable. The infrared camera is positioned lower and gives a different view of the nest.
Does the light at night annoy Molly?
There is some ambient light from the neighborhood, but there are no extra lights used at night. Molly doesn’t seem to mind.
Are the cameras actually inside the box?
No, they are attached to the exterior of the house with a protective cover.
How do you interface to Ustream?
Ustream has a wealth of information on how to connect a live camera to their site. For more information, visit:

Ich hoffe, das hilft vielleicht ein wenig. Ich weiss, in der Wildniss ist eine Steckdose nunmal nicht zu finden, vielleicht muss da ein kleines Stromwägelchen her oder ihr arbeitet mit Solarpower, sofern das überhaupt möglich ist.
