Internet Camera Features

1 What is an Internet Camera?

An Internet Camera is a standalone system that connects directly to an Ethernet or Fast Ethernet network and supported by the wireless transmission based on the IEEE 802.11g standard, whereas conventional PC Cameras require connection to a powered PC to function. An Internet Camera is an all-in-one system with a built-in CPU, providing a low cost web-based solution that can transmit high quality video images for monitoring. The Internet Camera can be managed remotely, and can be accessed and controlled from any PC locally or through the Internet via a Web browser.

2 What is the maximum number of users that can be allowed to access DCS-2102/2121 simultaneously?

The maximum number of users that can log onto the Internet Camera at the same time is 10. Please keep in mind that overall video performance will slow down when multiple users are logged on.

3 What algorithm is used to compress the digital image?

MPEG-4 and MJPEG are used to provide high quality images at low bandwidths.

4 Can I capture still images from the Internet Camera?

Yes. You may record snapshots using the snapshot feature on the Home page. When viewing this page, press the “snapshot” button to capture the image and save it to your hard drive.

5 Can the Internet Camera be used outdoors?

The Internet Camera is not weatherproof and is not recommended for outdoor use.

6 What network cabling is required for the Internet Camera?

The Internet Camera uses Category 5 UTP Twisted-pair cable for 10 Base-T and 100 Base-T networking.

7 Can the Internet Camera be used as a webcam for my computer?

No, the Internet Camera only functions through an Ethernet or wireless (DCS-2121 only) network. Other cameras such as the D-Link DSB-C110 and DSB-C310 can be used as a PC Camera (webcam).

8 Can the Internet Camera be connected to a network if it consists of only private IP Addresses?

Yes, the Internet Camera can be connected to a LAN with private IP Addresses.

9 Can the Internet Camera be installed if a firewall exists on the network?

If a firewall exists on the network, port 80 needs to be opened for data communication. You will need to do port forwarding by opening a port to the camera. Please refer to your firewall’s product manual for detailed instructions.

DCS-2102, DCS-2121 specifications

D-Link DCS-2121 and DCS-2102 are cutting-edge network cameras designed for unparalleled surveillance in homes and businesses. Both models integrate advanced technologies that deliver high-quality video and robust security features, making them popular choices among users seeking reliable monitoring solutions.

The DCS-2121 is equipped with a 1.3-megapixel sensor that provides exceptional image clarity and detail, which is crucial for effective surveillance. It supports video resolution of up to 1280x1024 pixels, enabling users to capture fine details even in large spaces. The camera also boasts a wide dynamic range, enhancing its ability to capture clear images in challenging lighting conditions, such as bright sunlight or complete darkness.

On the other hand, the DCS-2102 features a 1.0-megapixel sensor, delivering impressive video quality with resolutions up to 720p. While it offers slightly lower image quality compared to its counterpart, it still provides sufficient clarity for various monitoring needs. Both cameras support H.264 compression technology, which significantly reduces file sizes while maintaining high video quality, making it easier to manage and store recorded footage.

One of the standout features of both models is night vision capability. They are equipped with infrared LEDs, allowing for clear visibility in complete darkness, which is essential for 24/7 surveillance. This is complemented by automatic IR cut filters that switch between day and night modes seamlessly, ensuring optimal image quality regardless of the time.

Connectivity is another crucial aspect, as both cameras come with Ethernet ports for wired connections and support Wi-Fi for wireless installation. This flexibility enables users to set up the cameras according to their specific needs and environments. Furthermore, they offer remote access capabilities, allowing users to monitor live feeds via web browsers or mobile applications from anywhere in the world.

To enhance security, the DCS-2121 and DCS-2102 benefit from motion detection technology, which triggers alerts and recording events when movement is detected. This feature helps conserve storage space and ensures that critical incidents are always documented.

In summary, the D-Link DCS-2121 and DCS-2102 network cameras present a compelling combination of image quality, versatility, and advanced surveillance technologies. Whether for home security or business monitoring, these models deliver reliable performance and peace of mind, making them valuable assets in any security system.
