Chapter 6 Troubleshooting
Symptom I cannot connect to the IP camera using a wireless connection.
Solution If a LAN cable is connected to the LAN port, the wireless interface is disabled. Only one
interface can be active.
Check that your PC and the IP camera have compatible Wireless settings:
• Mode (Infrastructure or Ad-hoc) must be correct.
• ESSID must match.
• WEP settings must match.
• In Ad-hoc mode, the channel should match.
Symptom Video quality suddenly deteriorates.
Solution This situation can occur when an additional viewer connects to the IP camera, overloading the
camera or the available bandwidth. The image size and quality can be for the required number of viewers
and the available bandwidth.
Symptom The motion detection feature does not send e-mail alerts.
Solution The SMTP (Simple Mail Transport Protocol) server used by the camera to send the e-mail may
not accept mail (to prevent spam from being sent from the server). Try using a different SMTP server,
or contact your ISP to see if SMTP access is being blocked.
Symptom Using the motion detection feature, I receive e-mail messages that do not show any moving
objects.
Solution The motion detection feature does not actually detect motion. It compares frames to see if they
are different. Major differences between frames are assumed to be caused by moving objects. But the
motion detector can also be triggered by:
• Sudden changes in the level of available light
• Movement of the camera itself.
Try to avoid these situations. The motion detection feature works best in locations where there is good
steady illumination, and the camera is mounted securely. This feature may not work properly if the
camera is outdoors.
Symptom The image is blurry.
Solution Try cleaning the lens, or adjusting the image settings on the video screen. Video created with
lower settings contains less detail, which is a trade-off for using less bandwidth.
