Q. My video quality suddenly deteriorated.
This can happen when an additional viewer connects to the Wireless
Network Camera, overloading the camera or the available bandwidth. The
image size and quality can be adjusted to cater for the required number of
viewers and the available bandwidth.
Q. The motion detection feature doesn't send me any e-mails.
The Cisco WVC210 camera does not support Secure Sockets Layer (SSL)
protocols used by many e-mail providers, such as Gmail. Therefore you will
not be able to use Simple Mail Transport Protocol (SMTP) Mail servers like
Gmail that require SSL encryption. Contact your e-mail provider if you are
not sure whether your SMTP server uses SSL encryption.
You must use a static IP address (you can copy the DHCP Address), but the
DNS server must be that of the ISP and not of the router. You can find this
address in the router's status log for WAN IP Address.
Q. When using the motion detection feature, I receive e-mails that don't
show any moving objects.
The motion detection feature doesn't 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 or movement of the camera itself. For example,
twilight, like dusk and dawn, can cause false positive detections. Motion
detection should not be used if the camera is outdoors because of the
possibility of false positives. The motion detection feature works best in
locations where there is good steady illumination, and the camera is
mounted securely.
