This is the brain of a PTZ camera. Most people never even know what these PTZ cameras are made of, so here is an example. This camera features a 1/4 type EXview HAD? CCD and high sensitivity of 1.5 lux (50 IRE). Exview is powerful chip-set technology, where infrared and non-infrared cameras (like this ptz camera lens) renders more detail and brighter images to give better video in very tough lighting conditions. Exview was created and coined initially by Sony. However, this is a snap shot of what the brain of a ptz surveillance camera looks like. So inside the shell of all PTZ cameras this is were the magic happens.
