1 What is an Internet Camera?

The Internet Camera is a stand-alone system connecting directly to an Ethernet or Fast Ethernet network. It differs from a conventional PC Camera, the Internet Camera is an all-in-one system with built-in CPU and Web-based solutions providing a low cost solution that can transmit high quality video images for monitoring. The Internet

Camera can be managed remotely, accessed and controlled from any PC/Notebook over an Intranet or the Internet from a Web browser.

2. What is the maximum number of users that can be allowed to access DCS-5605/5635 simultaneously?

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

3. What algorithm is used to compress the digital image?

The Internet Camera utilizes H.264 Simple Profile Mode image compression technology to provide high quality images.

4. Can I capture still images from the Internet Camera?

Yes you are able to capture still images with the snapshot function from the software application CD supplied with the Internet Camera or with the snapshot function on the Home page using an Internet browser.

5. Can the Internet Camera be used outdoors?

The Internet Camera is not weatherproof, and needs to be equipped with a weatherproof case in order to be used outdoors (recommended).

6. When physically connecting the Internet Camera to a network what network cabling is required?

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

7. Can the Internet Camera be setup as a PC-cam on a computer?

No, the DCS-5635 Internet Camera is used only on a wireless 802.11n/g, Ethernet, or Fast Ethernet network.

8. Can the DCS-5605/5635 be connected to the 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 DCS-5605/5635 be installed and work if a firewall exists on the network?

If a firewall exists on the network, port 80 needs to be opened for ordinary data communication. The DCS-

5605/5635 uses HTTP port and RTSP port to stream video data. These ports (or the ports you specify from the

Advanced Tab in the Configuration screen if you change the default ports) need to be opened in the firewall device.

Please refer to page 77 for more information.

10. Why am I unable to access the DCS-5605/5635 from a Web browser?

If a router or firewall is used on the network, the correct ports for the DCS-5605/5635 may not be configured on the router or firewall. To correct the problem, you need to determine if the DCS-5605/5635 is behind a router or firewall and if the router or firewall is properly configured for the ports the DCS-5605/5635 is using. Refer to page 77 for help in opening the correct ports on a router or firewall for use with the DCS-5605/5635.

Other possible problems might be due to the network cable. Try replacing your network cable. Test the network interface of the product by connecting a local computer to the unit, utilizing a Ethernet crossover cable. If the problem is not solved the Internet Camera might be faulty.

11. Why does the Internet Camera work locally but not externally?

This might be caused by network firewall protection. The firewall may need to have some settings changed in order for the Internet Camera to be accessible outside your local LAN. Check with the Network Administrator for your network.

Make sure that the Internet Camera is not conflicting with any Web server you may have running on your network.

The default router setting might be a possible reason. Check that the configuration of the router settings allow the

Internet Camera to be accessed outside your local LAN. Please refer to page 77 for more information.

12. I connected the Internet Camera directly to a computer with a cross-over cable Ethernet cable and received the following Windows error upon running the Installation Wizard:

This Windows error will occur if the Internet Camera is connected to a computer that is not properly configured with a valid IP address. Turn off DHCP from the Network Settings in Windows ® and configure the computer with a valid IP address, or connect the camera to a router with DHCP enabled.

13. Why does a series of broad vertical white lines appear throughout the image?

It could be that the CMOS sensor has become overloaded when it has been exposed to bright lights such as direct exposure to sunlight or halogen lights. Reposition the Internet Camera into a more shaded area immediately as prolonged exposure to bright lights will damage the CMOS sensor.

14. Noisy images occur. How can I solve the problem?

The video images might be noisy if the Internet Camera is used in a very low light environment. To solve this issue you need more lighting.

15. The images appear to be of poor quality, how can I improve the image quality?

Make sure that your computer’s display properties are set above 256 colors. Using 16 or 256 colors on your computer will produce dithering artifacts in the image, making the image appear to be of poor quality.

The configuration on the Internet Camera image display is incorrect. Through the Image Setup section of the Web management you need to adjust the image related parameters such as brightness, contrast, hue and power line frequency for fluorescent light. Please refer to the Image Setup section on Page 49 for detailed information.
