In a method for detecting an abnormity of an image capturing device, an image of a monitored area is captured, and an image texture of the image is calculated according to the image. When a count of image textures recorded in a history record list is greater than a predetermined value, the method compares the image texture with at least two image textures recorded in the history record list, to determine whether the image is abnormal. If the image is abnormal, the method increments an abnormity record value of the image capturing device by a value of one. Once the abnormity record value is equal to an alert value, the method generates an alarm to warn of an abnormity of the image capturing device.
