Video Surveillance 2520 Series IP Dome is a feature-rich digital camera designed for superior
performance in a wide variety of video surveillance applications. The camera employs MPEG-4 and MJPEG
compression of up to 30 frames per second (fps) at D1 NTSC resolution (720 x 480) or 25 fps at D1 PAL resolution
(720 x 576), offering efficient network utilization while providing high-quality video. Two-way audio and contact
closures allow integration with microphones, speakers, and access control systems. This vandal-resistant dome is
designed to be deployed indoors. With its open, standards-based design, the camera provides an ideal platform for
integration and operation as an independent device or as part of a Cisco Video Surveillance network.

The Cisco Video Surveillance 2520 Series IP Dome offers a variety of benefits, including:
Wide dynamic range. The camera employs powerful digital imaging technology, allowing it to capture high-
quality images in a wide variety of lighting conditions. It uses a progressive scan image sensor with global
electronic shuttering to ensure natural color rendition, zero blooming and smear, and minimal motion blurring.
Dual streaming. The camera can stream MPEG-4 and MJPEG video simultaneously. Each video stream can
be configured with individual resolution, quality, and frame rate settings.
Embedded security and networking. The camera provides 802.1X authentication and hardware-based
Advanced Encryption Standard (AES). For enhanced bandwidth management, the camera supports
IP Multicast.
Event notification. The camera can examine designated areas in the video for motion activity and then notify
users or other applications when it detects activity that exceeds a predefined threshold. The camera also
provides two digital inputs and two digital outputs that can initiate specific actions when an alarm is detected.
Bidirectional audio. The camera supports full-duplex audio, and options for half-duplex operation.
Flexible power options. The camera supports Power over Ethernet (PoE) 802.3af, and 12 VDC or 24 VAC
power through an optional external power supply.
