Trendnet TV-IP751WIC [41/45] Troubleshooting

TRENDnet User’s Guide

TV-IP751WC/ TV-IP751WIC

Troubleshooting

1. The Power LED and Ethernet Activity LED do not light up.

The power supply or camera might be faulty. Check that the connection to both

the power source and the terminal on the back of the camera are secure and

that you are using the provided power supply. If the camera is otherwise

functioning correctly, the LEDs might have been disabled in the configuration.

See the section of this guide on Configuration of System settings.

2. The camera can’t be accessed or access is slow

There might be a problem with the network cable. To confirm that the cables

are working, ping the address of a known device on the network. If the cabling

is OK and your network is reachable, you should receive a reply similar to the

following (…bytes = 32 time = 2 ms).

Another possible problem may be that the network device such as a hub or

switch utilized by the Network Camera is not functioning properly. Please

confirm the power for the devices are well connected and functioning properly.

3. The camera can be accessed locally but not remotely

This might be caused by a firewall. Check the Internet firewall with your system

administrator. The firewall may need to have some settings changed in order

for the Network Camera to be accessible outside your local LAN. For more

information, please refer to the section about installing your camera behind a

router.

Make sure that the Network Camera isn’t 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 Network Camera to be accessed

outside your local LAN.

4. White vertical lines appear on the image from the camera

It could be that the CMOS sensor (a square panel situated behind the lens

that measures the light signals and changes it into a digital format so your

computer can present it into an image that you are familiar with) has become

overloaded when it has been exposed to bright lights such as direct exposure

to sunlight or halogen lights. Reposition the Network Camera into a more

shaded area immediately as prolonged exposure to bright lights will damage

the CMOS sensor.

5. The camera images are ‘noisy’

Often if the camera is in a low-light environment, the images can contain a lot

of noise. Try enabling Night mode and see if that improves the image quality.

Otherwise, try to use the camera in a location where there is a bit more light.

6. The camera images are of poor quality.

Make sure that your computer’s display properties are set to at least 16-bit

color. Using 16 or 256 colors on your computer will produce dithering artifacts

in the image, making the image look as if it is of poor quality.

Try also adjusting the brightness, contrast, saturation, light frequency and anti-

flicker controls on the Video Settings under the Configuration menu. You may

also consider adjusting the resolution of the camera and the compression rate

to improve the image.

7. Video can’t be viewed through the web browser interface.

ActiveX might be disabled. If you are viewing the images from Internet Explorer

make sure ActiveX has been enabled in the Internet Options menu. You may also

need to change the security settings on your browser to allow the ActiveX plug-

in to be installed.

If you are using Internet Explorer with a version number lower than 6, then you

will need to upgrade your Web browser software in order to view the

streaming video transmitted by the Network Camera. Try also viewing the

video using Java. Ensure that you have the latest version of Java installed

before you do. Go to www.java.com for more information.
