Troubleshooting
1. The camera is not work properly with standard 802.3af POE
This camera is an 802.3at PoE+ compatible appliance. If powered by an 802.3af
power sourcing equipment, it will not draw enough power for camera's IR LEDs.
To prevent this, please ensure it is being powered by an 802.3at power sourcing
equipment.
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
source.
6. 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.
7. The camera isn't sending email notifications from my gmail account.
Google's security settings may prevent the TV‐IP440PI from accessing your gmail
account to send notifications. To change the security settings, log into your
account, then click on your account settings. Under the Signing in section, locate
the Access for less secure apps setting, and click on it. Under the options, select
Turn on. This should allow the camera to send notifications from your gmail
account.
