The Cisco® Video Surveillance 3520 IP Camera is a high-definition, full-functioned video endpoint with industry-leading image quality and processing power. The camera is capable of resolutions up to 1280 x 800 at 30 frames per second (fps) while optimizing network usage with either H.264 or MJPEG compression. Contact closures allow integration with access control systems. 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 3520 IP Camera offers a variety of benefits, including:
• True high-definition video. The camera streams crisp and clear video at resolutions of up to 1280 x 800 at 30 fps while maintaining low network bandwidth.
• Dual streaming. The camera can stream H.264 and MJPEG video simultaneously. Each video stream can be configured with individual resolution, quality, and frame-rate settings.
• Day/night operation. The camera provides true day/night functionality and includes an infrared filter that automatically switches to night mode in low-light scenes. This function can be set to manual, automatic, or scheduled control.
• Privacy regions. The camera supports up to four user-defined privacy regions. Any video within a privacy region is masked in the video stream.
• Local storage. Video data can automatically be recorded to a microSD card when the camera loses network connectivity.
• Bidirectional audio. The camera supports full-duplex audio and options for half-duplex operation.
• Open API. Support for ONVIF 2.0 allows for standards based interoperability and communications with other ONVIF appliances.
• Flexible power options. The camera supports Power over Ethernet (PoE) 802.3af, 12 VDC, or 24 VAC power through an optional external power supply.
• Medianet support. The camera supports the Cisco Medianet interface. When connected to a Cisco switch that also supports Medianet, the switch recognizes the camera as a video endpoint and then uses SmartPort macros to set the right network parameters for the video stream on the network. In addition, the camera can be automatically discovered and configured when connected to Cisco Video Surveillance Manager 7.0, thereby minimizing installation time and cost.
