Camera trap

A camera trap is a remotely activated camera that is equipped with a motion sensor or an infrared sensor, or uses a light beam as a trigger. Camera trapping is a method for capturing wild animals on film when researchers are not present, and has been used in ecological research for decades. In addition to applications in hunting and wildlife viewing, research applications include studies of nest ecology, detection of rare species, estimation of population size and species richness, as well as research on habitat use and occupation of human-built structures.

Camera traps, also known as trail cameras, are used to capture images of animals in the wild with as little human interference as possible. The introduction of commercial infrared-triggered cameras in the early 1990s has seen their use dramatically increase. With advancements in the quality of camera equipment this method of field observation has become more popular among researchers. Hunting has played an important role in development of camera traps, since hunters like to use them to scout for game. These hunters have opened a commercial market for the devices which have led to many improvements over time.

Camera

A camera is an optical instrument for recording images, which may be stored locally, transmitted to another location, or both. The images may be individual still photographs or sequences of images constituting videos or movies. The word camera comes from camera obscura, which means "dark chamber" and is the Latin name of the original device for projecting an image of external reality onto a flat surface. The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye.

Functional description

A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene, and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens and an image is recorded on a light-sensitive medium. A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A display, often a liquid crystal display (LCD), permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed.

Eaten Alive (TV special)

Eaten Alive is an American nature documentary special which aired on Discovery Channel on December 7, 2014. The special focused on an expedition by wildlife author and entertainer Paul Rosolie to locate a green anaconda named "Chumana", which he believed to be the world's longest, in a remote location of the Amazon rainforest. The special was also purportedly to feature Rosolie being "eaten" by an anaconda, protected by a suit designed specifically for this purpose.

Though Rosolie stated that the special was intended to draw attention to wildlife conservation and the destruction of the Amazon, the special was condemned prior to its premiere by critics and the animal rights group PETA as an inhumane publicity stunt oriented towards shock value, resulting in calls for Discovery Channel to pull the special. After its premiere, Eaten Alive was widely criticized for false advertising. It did feature Rosolie attempting to feed himself to an anaconda, and the snake did attack, but did not swallow Rosolie as the title of the special implied. The stunt itself was called off due to safety concerns. One critic compared the special to The Mystery of Al Capone's Vaults—a television event that ended with a similarly disappointing outcome that did not meet promoted expectations.
