Not a bad deal if installed correctly


I'd like to see DLink list the part numbers of their 'optional accessories' on their website to make them easier to find and obtain. As a test, google DCS-3420 auto-iris and see what comes up. I would stay away from the trendnet series unless you just...

Excellent low light capability IF you play around with controls and figure them out. Using AGC under video controls helps a great deal for night vision. MUCH LESS artifact than any other cam I own (6 different cameras running under netcam watcher pro...

Not designed for outdoor use UNLESS your enclosure is outdoor/waterproof/sunshield AND you can find the autoiris lens which I have not found yet. Standard C mount lenses obviously require an adapter (not included). I am unable to easily locate a D-Link...

Product Specifications

The DCS-3420 Wireless Day & Night Internet Camera is a versatile security system that allows you to watch and listen remotely from anywhere. This full-featured camera connects to Ethernet wired or wireless networks in a building or campus and via broadband to the Internet. Equipped with a high-quality CCD sensor, digital zoom, low-light / no light capabilities and advanced software functions for multi-camera monitoring and management, this camera provides a comprehensive system for surveillance over a LAN or the Web. In order to ease migration from traditional analog CCTV surveillance to IP-based digital systems, the DCS-3420 includes a standard BNC connector for analog CCTV video. The inclusion of both Ethernet and BNC connections allows you to simultaneously incorporate the DCS-3420 into both digital and analog surveillance systems. The DCS-3420 may be used outdoors, when placed in a suitable enclosure such as the DCS-60. The DCS-3420 uses MPEG-4 Simple Profile Mode to stream live video at up to 25 frames per second for real-time viewing. A CCD sensor provides sharp video images with lifelike color representation and a 4x digital zoom capability allows for close-up viewing over the Web interface. With low-light capability, the camera can monitor and record video in rooms with minimal or no lighting, making it ideal for use in dark places. Through a built-in microphone, you can watch and listen remotely as the DCS-3420 captures both sound and video from your site. The DCS-3420 takes surveillance to another level using two-way audio. By adding a powered speaker (not included) to the DCS-3420, you can also talk remotely with anyone at your camera site. For effective surveillance in and around a building, this camera comes with a built-in high-speed 802.11g wireless network interface, which supports WEP and WPA-PSK encryption, allowing for images to be transmitted securely at up to 54Mbps. A 10/100Base-TX Ethernet port is also provided to allow connection to a wired Ethernet network or directly to the Internet via a broadband router.
