Note: After resetting the D-Link DCS-6620/DCS-6620G to default, the Auto Electronic Shutter (AES) is set to Auto. Some environmental lighting may affect the D-Link DCS-6620/DCS-6620G to a point where the video is unrecognizable. To fix this the CCD Settings must be changed.

Step 1: Log in to the web configuration of the D-Link DCS-6620/DCS-6620G.

Step 2: Select Configuration from the left hand menu.

Step 3: Click CCD on the left hand side.

Step 4: Using the Auto Electronic Shutter drop down menu, select the appropriate shutter speed. You may need to test different shutter settings for your environment.

Step 5 Use the references below to help you decide which settings your environment requires you to change.

Help File References:

Auto Electronic Shutter (AES) In this mode the AES will be fixed at 1/60 (1/50) second. The default setting of the CCD is in the auto-iris mode. If the shutter is selected to auto, the iris of the CCD will become fixed. Faster shutter speed will allow fast moving objects to be seen more clearly.

Auto tracking white balance This is helpful if the camera is monitoring outdoor objects. There are 9 levels of white balance that can be adjusted that will help the camera to capture video with correct colors.

White balance control Selecting this feature will disable the Auto tracking white balance. This is used mostly for monitoring indoor objects. Adjustments are from 3200K-8000K to get the correct colors.

Auto switch to B/W in low lux mode Selecting this option and the low lux mode will automatically switch video to black and white if the environment became dark such as going from evening to night.

Enable BLC This is for back light compensation. When object is in front of bright lights it is sometimes difficult to see, selecting this option and adjust sensitivity level can allow object to become clearer to see.

BLC sens level Adjusting this will allow objects to be seen more clearly by adjusting BLC sensitivity detection.

BLC area selection A selection window will pop up. The window is divided into 48 squares, select the squares that BLC is required; if no squares are selected there will be no differences in the video.

The firmware upgrade process for all D-Link managed switches runs over TFTP. You will need TFTP software running on the computer that has the Firmware file on the local hardrive. If you do not have TFTP software, it is freely available on the Internet.

The Firmware upgrade procedure requires an Ethernet connection between the switch and the TFTP server. You must be able to access the switch through Telnet or the Web based configuration from the computer that is running the TFTP software. Although there are many different ways to configure the switch, it is easiest for you to use the Web based configuration when upgrading the Firmware.

The Web based configuration of any D-Link switch can be accessed by entering the IP address in the address bar of any Java-enabled browser. The default IP address of the D-Link DES-3226 is 10.90.90.90/255.0.0.0. If you are unable to access the web based configuration, connect to the switch through Hyperterminal and reset the switch to Factory default. If you have made configuration changes to the switch, make sure that your TFTP server is on the Management VLAN, and that it can PING the switch.

Step 1 Open your Web browser and enter the IP address of the DES-3226 in the address bar (10.90.90.90). Select Login at the top of the web page. When prompted, enter the username/password that you have assigned to the switch. By default there is no username or password assigned to the switch.

Step 2 From the folder tree on the left-side of the page select Maintenance>TFTP Services>Update Firmware.

A10472_image2

Step 3 Enter the IP address of the computer running the TFTP software in the field labeled Server IP Address. In the field labeled File Name, enter the path to the firmware file that is on the local hardrive of the computer running the TFTP software. Make sure that you include the file extension of the firmware file when specifying the directory path.

A10472_image3

Step 4 Make sure that there is TFTP software running on the computer who-¦s IP address was entered in the Web based configuration. Click on the Apply button, and then click on Start.

Step 5 During the upgrade process this is what you should see. The D-Link TFTP software is also shown in the below screenshot which will also display the firmware upgrade status.

A10472_image4

Step 6 After the Firmware upgrade is complete the switch will automatically reboot. Wait 1-2 minutes and then reconnect to the switch. Login and select Configuration>Switch Information. The field labeled Firmware Version should now display the Firmware Version that you just upgraded to.

Scenario:

VLAN 1 can communicate with VLAN 2 but VLAN2 cannot access VLAN 1. Both VLANS can access the internet.

DFL-210/800/1600:
Lan Interface: 192.168.1.1
VLAN1: 192.168.2.1

Note: This FAQ uses the D-Link DIR-632 as an example. Your screen may look different than the image below.

QoS (Quality of Service) is designed to shape and prioritize your internet traffic among the computers on your LAN. This allows for an optimized internet experience.

To set up QoS in your router, use the following steps:

Step 1: Open a web browser and type the IP address of the DIR series router into the address bar (default is http://192.168.0.1).

Step 2: The default username is admin (all lower case) and the default password is blank (nothing). Click on OK.

Step 3: Click on the Advanced tab at the top and then click on QOS Engine on the left hand side.

WAN TRAFFIC SHAPING

  • Enable QoS Engine: Enable this option for better performance and experience with online games and other interactive applications, such as VoIP.
  • Automatic Uplink Speed: When enabled, this option causes the router to automatically measure the useful uplink bandwidth each time the WAN interface is re-established (after a reboot, for example).
  • Measured Uplink Speed: This is the uplink speed measured when the WAN interface was last re-established. The value may be lower than that reported by your ISP as it does not include all of the network protocol overheads associated with your ISP’s network. Typically, this figure will be between 87% and 91% of the stated uplink speed for xDSL connections and around 5 kbps lower for cable network connections.
  • Manual Uplink Speed: If Automatic Uplink Speed is disabled, this option allows you to set the uplink speed manually. Uplink speed is the speed at which data can be transferred from the router to your ISP. This is determined by your ISP. ISPs often specify speed as a downlink/uplink pair; for example, 1.5Mbps/284kbps. For this example, you would enter “284”. Alternatively you can test your uplink speed with a service such as www.dslreports.com. Note however that sites such as DSL Reports, because they do not consider as many network protocol overheads, will generally note speeds slightly lower than the Measured Uplink Speed or the ISP rated speed.

Step 4: Click Save Settings.
