The Sony EVI-D90 is a smartly styled PTZ (pan/tilt/zoom) camera ideal for a wide range of security, video conferencing, distance learning and remote monitoring applications. The 1/4-type EXview HAD CCD sensor ensures crisp standard definition picture quality, even in dim ambient lighting conditions. The stepper motor enables smooth pan/tilt/zoom operation while the 28x optical zoom range allows frame-filling close-ups, and built-in image stabilization reduces the effect of shaky images caused by wind or vibration.
