Troubleshooting Your Wireless Outdoor Camera
Poor Picture:
Realign antennas until image quality improves, slightly adjust the position of the Camera or
Receiver. Change the location of the Camera, or use a different height or angle to see if the
image improves. In some cases interference may be caused by another device on a similar
frequency to the channel you are using.
Lines only - no clear picture:
Check to confirm there is no microwave oven or other 2.4GHz equipment operating close by
ie; Cordless Telephones, Wireless Baby Monitors, Wireless LAN equipment etc . Make sure
the Receiver is on the correct channel.
Picture ghosting or interference:
Some home appliances such as Wireless LANs, 2.4GHz portable telephones and
Microwave ovens operate on or near the 2.4GHz frequency. If you receive interference from
such an appliance, try moving the Camera or Receiver to location further away from the
appliance or in the event of interference from a Wireless LAN device, try changing the
Wireless LAN to a different channel to improve the signal quality.
No picture:
Check the receiver to confirm it is turned ON and make sure the A/V connection of the
Receiver is not plugged into the Audio Out socket. Make sure the Receiver is on the correct
channel. Check to ensure the camera is plugged in and has power. Check that the channel
on the receiver is the set to Channel x.
Red haze over picture:
In some cases where the sun shines into the front of the camera a faint red glow can be
seen. Move the camera to a shaded location, or fit a hood to stop sunlight entering the
camera lens directly.
Foreground is dark while background is too bright:
If the camera is looking from a dark area towards a light area in some cases the automatic
exposure can find it difficult to balance the image correctly. Change the location of the
camera so that the point of greatest interest has the largest area of the image.(if you want to
see the bright area, move the camera so that almost all of the screen shows this area. If you
want to see the darker area, move the camera so that most of the image shows this area.

Changing these switch settings changes the frequency that
the camera transmits on. Once you have set the channel on
the camera, select the same channel on your RedAlert. If you
experience interference try different channels. Make sure
multiple cameras are set to different frequencies so you can
use them in the same area with the DVR.
