Cameras are delicately tuned pieces of equipment. It just takes one small crack on a camera lens for the entire vision ability of the camera to be hindered.
Its important to know how the weather can cause adverse affects such as this, and to take appropriate measures to avoid any unnecessary damage.
A method for protecting your camera is to consider where you are placing it. Is it in a sheltered area? Is it in a place that the wind usually wails through violently? Can you see if there are any potential branches that may swipe into the vicinity of the camera? If so it may be wise to select a safer spot see this.
Its also to important to consider the quality of the camera. Is it weather proof? It may seem obvious but cameras range in quality, some are not designed for outdoor use whatsoever. Take some time in assessing if the camera you have or are looking at is suited for all weather conditions.
Being aware of potential weather threats can go a long way in preventing unwanted mishaps.
