CCD Sensor for Enhanced Image Expression This camera features a CCD (Charged Couple Device) for sharp, enhanced image expression. The image refreshing speed (maximum) has been increased to 30 images per second3 for smoother displays of moving images. Record Directly onto SD Cards The camera features an SD Memory Card slot for recording images captured by the network camera directly onto an SD Memory Card (sold separately). Control the Camera Remotely Using a standard Web browser, video display, or even a compatible cell phone or PDA, you can control the movement of the camera. There is 350 Pan (left & right) movement and 210 Tilt (up & down) movement available. You can also assign a "Home Position" that allows you to return the camera to a pre- designated shooting position. Up to eight shooting positions can be registered in advance, so you can aim the camera exactly where you want it. You can also click on the part of the image you want to see, and automatically bring that part to the center of the screen. Sensor Recording and Image Alerts With the built-in sensor, the camera can be set to record and/or notify you when someone enters the room. It can even automatically move to a preset location when triggered, just in case someone was viewing a different part of the room.
