The IP cameras deliver professional surveillance, with ease of installation and set-up, for a variety of network surveillance requirements. The remote focus module allows users to simply click "Short-range Focus" or "Full-range Focus" saving installers time and end users money - an easy return on investment. The three-axis lens adjustment provides users with more camera placement options, allowing the cameras to be easily mounted on a wall or ceiling so they can pan, tilt, and rotate the lens in a variety of directions for a precise field of view. A spring arm design makes in-ceiling installations a snap: simply slide the camera through the hole and secure the magnetized cover ring with a single screw. No additional hardware is required.
