Up to 16 preset positions (with different settings for pan, tilt and zoom) can be registered for a single VCCP9574N. A simple key entry to a controller allows you to easily switch to the scene you want to monitor. Auto-pan monitoring can be also be programmed by designating two end points on a horizontal plane.The VCC-P9574N comes with a PT mechanism and allows panning of 335 degrees and tilting of 90 degrees to reduce blind spots in the surveillance area. When particular angles are preset on the camera (up to sixteen points), it moves to each position quickly at the speed of 120 deg/sec. max. for both panning and tilting. Combining these features with the motion detector, it is possible to catch all actions taking place in the area.The VCC-P9574N features two selectable backlight compensation modes: multi-spot metering (applied to the whole screen) and center-zone metering (applied to the central portion only).Sensing is performed by splitting the field of view into 16 areas. Movement and brightness levels within the picture are analyzed to accurately detect surveillance targets. Upon detection, the camera sends an alarm status signal and captures the object at zoom magnifications of up to x2.6. Fine adjustments of settings such as sensitivity, tracking time, zoom ratio and areas not requiring detection can also be made.When there is a house or even an object as small as a window within the camera frame, it is possible to mask the area so that it will not appear on the monitor screen to protect other's privacy. Up to 8 rectangular masks of arbitrary size can be set. These masking areas may be protected with a 4-digit (max) password.A high-speed electronic shutter that is internally switchable for eight modes using a DIP switch allows adjustment increments from 1/60 to 1/10,000 sec.
