Abstract: A monitoring camera includes a camera lens, an image sensor, and a housing enclosing the image sensor. The housing encloses a volume of Phase Changing Material (PCM) having the characteristic of not beginning a phase change until its temperature rises above a predetermined phase changing temperature. The phase changing temperature is in the range of 20-80 degrees Celsius, and the PCM is arranged to enclose the camera lens.
