Interference these days on 2.4 Ghz is rampant !
The following are steps to help eliminate your interferences:
To get your X-10 2.4 Ghz wireless camera working properly,
first unplug all Cordless Phones and Wireless Networks,
take out batteries of wireless Thermometers and Caller ID
devices, and any other wireless device in your home,
that you suspect may transmit on 2.4 Ghz.
Now check your X-10 Camera.
If the picture is good, then you can continue by plugging in
your other electronics one step at a time. Each time verifying
that the picture quality has not changed. Sooner or later you
will discover that something was interfering with the X-10 Camera.
The next step is to try each of the four X-10 Channels A thru D.
This must be done by setting the slide switch on BOTH the
Receiver and the Transmitter. After trying each combination
of the four channels, and you still have a interference problem,
here are your options;
If the problem was found earlier to be caused by a Cordless Phone
then you need to replace this phone with either the old school 900Mhz
or the newest band of 5.8Ghz Cell Phones. One very important point,
All 5.8 Ghz phones are not equal. There are 5.8 Analog, and 5.8 Digital, and 5.8 Spread Spectrum.
No matter which phone you chose, make sure it says "Wireless Network Friendly" on the box.
The reason is that not all 5.8 Ghz phones transmit and receive in
the 5.8 Ghz range. Look at the specifications in the manual or on the web. Most manufacturers
have downloadable manuals or otherwise post the cordless phone specs on the web.
What you will find is that many Transmit in 5.8Ghz and Receive in 2.4Ghz (or visa-versa), while still calling themselves
a 5.8 Ghz Cordless Phone. The "Wireless Network Friendly" units will all transmit and receive on 5.8Ghz.
If your Wireless Network was found to be the problem, you can search this forum for "Wireless Networks"
and find many posts taliking about interferences and listing the various frequencies of Router and X-10 Channels.
Here's a quick recap of those various posts;
X10 camera center frequencies: (note these vary +/- .010 Ghz)
Channel Frequency (Ghz)
A 2.411
B 2.437
C 2.455
D 2.471
Router Channel center frequencies for 802.11b and 802.11g:
Channel Frequency (Ghz)
1 2.412
2 2.417
3 2.422
4 2.427
5 2.432
6 2.437
7 2.442
8 2.447
9 2.452
10 2.457
11 2.462
First try setting your X-10 Camera for Channel A, and the Wireless Router for Channel 11.
This did not work for me, but the other end did. I set my X-10 Camera for Channel "D",
and my wireless router on Channel 1, and that solved my no picture interference problem.
To change channels on your wireless router, consult your manual or tech support.
There is usually a utility you can run or access on the web, which will allow you to change
the router channels. Just do a search "Changing Router Channels <manufacturer name here>",
and this will get you started in the right direction. Good Luck !
