Camera Types
The earliest models used traditional film and a one-shot trigger function. These traditional cameras contained film that needed to be collected and developed like any other standard camera. Today, more advanced cameras utilize digital photography, sending photos directly to a computer, even though this method is uncommon it is still highly useful and could be the future of this research method. Some cameras are even programed to take multiple pictures after a triggering event.
There are non-triggered cameras that either run continuously or take pictures at specific time intervals. The more common ones, however, are the more advanced triggered cameras that go off only after sensing movement and/or a heat signature to increase the chances of capturing a useful image, infrared beams can also be used to trigger the camera. Video is also an emerging option in type of camera traps, allowing researchers to record running streams of video, to document animal behavior.
The battery life of some of these cameras are another important factor in which cameras are used; large batteries offer a longer running time for the camera but can be cumbersome in set up or when lugging the equipment to the field site .

Famous quotes containing the words camera and/or types:
“When van Gogh paints sunflowers, he reveals, or achieves, the vivid relation between himself, as man, and the sunflower, as sunflower, at that quick moment of time. His painting does not represent the sunflower itself. We shall never know what the sunflower itself is. And the camera will visualize the sunflower far more perfectly than van Gogh can.”
—D.H. (David Herbert)
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
