Effects of Weather and The Environment
Humidity has a highly negative effect on camera traps and can result in camera malfunction. This can be problematic since the malfunction is often not immediately discovered, so a large portion of research time can be lost. Often a researcher expecting the experiment to be complete will trek back to the site, only to discover far less data than expected – or even none at all.
There is also the possibility, if it is a motion activated camera, that any movement within the sensitivity range of the camera’s sensor will trigger a picture, so the camera might end up with numerous pictures of anything the wind moves, such as plants.
The best type of weather for it to work in is any place with low humidity and stable moderate temperatures.
As far as problems with camera traps, it cannot be overlooked that sometimes the subjects themselves negatively affect the research. One of the most common things is that animals unknowingly topple a camera or splatter it with mud or water ruining the film or lens.
One other method of animal tampering involves the animals themselves taking the cameras for their own uses. There are examples of some animals actually taking the cameras and snapping pictures of themselves.
An interesting side note is that locals in the area of a camera trap who sometimes use the same game trails as the animals to move through the forest can be caught on camera. This adds to the human dynamic of the research and can make camera’s a useful tool for anti-poaching or other law enforcement effort.

Famous quotes containing the words effects of, effects, weather and/or environment:
“Some of the greatest and most lasting effects of genuine oratory have gone forth from secluded lecture desks into the hearts of quiet groups of students.”
—Woodrow Wilson (1856–1924)
“Virtues are not emotions. Emotions are movements of appetite, virtues dispositions of appetite towards movement. Moreover emotions can be good or bad, reasonable or unreasonable; whereas virtues dispose us only to good. Emotions arise in the appetite and are brought into conformity with reason; virtues are effects of reason achieving themselves in reasonable movements of the appetites. Balanced emotions are virtue’s effect, not its substance.”
—Thomas Aquinas (c. 1225–1274)
“And there could I marvel my birthday
Away but the weather turned around. And the true
Joy of the long dead child sang burning
In the sun.”
—Dylan Thomas (1914–1953)
“Autonomy means women defining themselves and the values by which they will live, and beginning to think of institutional arrangements which will order their environment in line with their needs.... Autonomy means moving out from a world in which one is born to marginality, to a past without meaning, and a future determined by others—into a world in which one acts and chooses, aware of a meaningful past and free to shape one’s future.”
—Gerda Lerner (b. 1920)
