If the suggestions above don’t provide enough improvement in the the signal quality, you may
want to run the camera at QVGA or zoom mode. When the camera is in zoom mode, it sends fewer
pixels to the receiver, so the video performance is not as affected by the weak signal.
Noise or Static
The most likely cause of noise (flickering image) or static is interference. There are many common
sources of interference:
►
electrical appliances, especially microwave ovens
►
computer equipment, especially wireless LAN equipment
►
other radio‑based wireless devices, such as cordless telephones
►
wireless controllers, or wireless headphones or speakers
►
large florescent light fixtures (especially if they give off a buzzing noise)
►
working motors (hair dryers, heater/air conditioners, water pumps)
If the static is only on 1 camera If the static is on all cameras
-Check near the camera for one of the common
interference sources.
-Try moving the camera away from a suspected
source, or try moving the suspected source so it’s
not between the camera and the receiver.
-Try moving closer to the receiver. There is always
more noise at the edges of the receiver’s range.
-Check near the receiver for the source of
interference.
-Try moving the receiver away from a
suspected source, or turn off the source if
possible.
-Try raising the receiver’s antenna so it
stands straight up.
