VC 220 Dome WDR Day/Night PoE Network Camera Administration Guide
Thank you for purchasing the Cisco VC 220 Dome Wide Dynamic Range (WDR)
Day/Night PoE Network Camera, a standalone camera that can be connected
directly to an Ethernet network. The Cisco VC 220 provides 24-hour surveillance
for indoor applications. The camera features day and night functions with a
configurable IR-cut filter and IR illuminators. A 3-axis mechanism allows for flexible
wall or ceiling installations in locations such as banks, office buildings, or
commercial complexes.
In sunlight, the IR-cut filter is activated to minimize the influence of infrared light on
image color. In the low-light conditions, the built-in IR illuminators are enabled to
offer infrared light for up to 15 meters (50ft). Therefore, the Cisco VC 220 delivers
high image quality in either day and night conditions. To prevent false alarms, a
passive infrared (PIR) sensor is built in to detect objects by their thermal presence.
By enabling Wide Dynamic Range (WDR), the camera can compensate for
challenging lighting conditions. Use WDR when there are both very bright and very
dark areas simultaneously in the field of view of the camera. The WDR feature
captures both the bright and dark parts of an image and combines the differences
to generate a highly realistic image representative of the original scene. The video
quality achieved is close to the capabilities of the human eye. WDR is widely
applied in high contrast environments such as lobby entrances, parking lots, ATMs,
or loading areas.
Before installing a surveillance system, check with local government agencies to
determine if video surveillance and audio monitoring are permitted in your area.
