D-Link DCS-3511 – HD PoE Network Camera with 1MP CMOS Sensor, 2.8–12mm Varifocal Lens, ePTZ & microSD Slot
Overview:
The D-Link DCS-3511 is an HD PoE Network Camera designed for professional surveillance applications requiring high-definition video and flexible installation.
It features a 1 Megapixel Progressive Scan CMOS sensor and a 2.8 mm to 12 mm DC iris varifocal lens for adjustable field-of-view coverage.
The camera supports HD video resolution up to 1280 × 800 and can record up to 30 fps depending on network conditions.
Power over Ethernet (PoE) allows power and data transmission through a single network cable, simplifying installation and reducing the need for a nearby power outlet.
Built-in ICR support enables 24-hour surveillance, while ePTZ allows virtual pan, tilt and zoom operation over the camera image.
The microSD/SDHC card slot allows local storage of snapshots and video without requiring a PC or network storage device.
D-ViewCam software support allows remote management and viewing of up to 32 cameras from one central location.
