3. The image on the Live View is blurry or out of focus, what can I do?
You can manually adjust the focus of the lens by rotating the bezel on the front of the camera (surrounding the lens). While watching the Live View,
rotate the bezel until the desired level of focus is achieved.
4. Why don't the LEDs light up?
The power supply might be faulty. Confirm that you are using the provided DC 12V power supply for this camera. Verify that the power supply is
correctly connected. The WPS LED will only turn on if there is a WPS connection present, the camera may still be functioning correctly even if this
LED is not lit. If the camera is functioning normally, the LEDs may have been disabled. See "Admin" on page 45 for information about how to
enable the LEDs.
5. Why is the camera's network connection unreliable?
If you are using a wired connection to connect the camera, 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 possibility 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.
If you are using a wireless connection to connect the camera, be aware of the range limitations of the wireless N standard. Most wireless N devices
have a maximum indoor range of around 230 feet (70 metres). Also be aware that obstacles such as walls, floors, doors and other solid objects can
have an adverse effect on signal range.
6. Why does a series of broad vertical white lines appear throughout the image?
It could be that the image sensor has become overloaded when it has been exposed to bright light such as direct exposure to sunlight or halogen
lights. Move the camera into a more shaded area immediately, as prolonged exposure to bright lights will damage the sensor.
7. The camera is producing noisy images. How can I solve the problem?
The video images might be noisy if the camera is used in a very low-light environment. Try switching to night mode if you are consistently monitoring
a low-light area.
