Abstract: A monitoring camera includes a camera unit that has a lens, a housing that has an opening facing a light incident surface of the lens and surrounds the camera unit with a gap which is formed between the housing and the camera unit, a light-transmissive cover that is attached to the opening with spaced apart from the lens to seal off the housing, a fan that is disposed in the gap and circulates an air in the gap, a ventilation hole that is bored in the housing and causes the gap to be open to an outside, a water-proof air-permeable film that covers the ventilation hole, a heater that is provided facing the gap and heats the air, and an infrared light irradiation device that is provided facing the gap and emits infrared light to the outside through the cover and radiates heat into the air.

Abstract: An image server and an image communication system capable of displaying images of plural image servers differing in IP address on a browser window by using a versatile browser, and a methods for controlling them. Plural image servers communicate with a client computer displaying image information presented from image servers through a network. Of the plural image servers, the controller of a certain image server receives a request from the client computer, and displays the image data of the image server and image data of other plural image servers simultaneously on the browser window of the client computer. Accordingly, the controller of the designated image server creates display information, and supplies the information to the client computer.
