Dome security CCTV surveillance cameras are named for their dome like shape. Dome cameras are commonly used in Surveillance Systems inside of Casinos, Retail Stores, and Restaurants. This is because dome cameras are more fashionable and blend in very well to their surroundings. Because of their dome shape, it is difficult for someone to tell which direction the lens of a Dome Camera is actually aiming.
If the area that you are installing your camera is susceptible to vandalism or tampering, you should consider installing an vandalproof dome camera. Housings are available for weather or vandal resistance or for use in hazardous (explosion risk) environments. A varifocal dome camera gives you the flexibility to adjust the focal distance of the camera lens to exactly where you need it.
