I can only get one or the other. The Network blocks out the camera.

Interfere in what way? We're just about to start up the same.

Hi these two suckers interfere with each other. What do i do?
Thanks

Not too surprising when both use the same frequency... Does the video have
switches to change band? If not, there's not a lot you can do about it
except change one or the other to different frequencies... You'll also find
microwave ovens interfere too... :(

i have changed to all 4 frequncies - no help

What can i do, meaning what other solutions are out there?

Typically, the video repeaters will wipe out the routers, but the routers
will only cause noise to the video repeaters (popping sound and streak in
the video at about 1 or 2 pps).

The video repeaters (at least the ones I've seen) have a switch on each end
that lets you pick one of four channels. If you try any of this stuff, try
it first with the video set on the first channel, then the last. Avoid the
channels in the middle.

Some of the 802.11 stuff is spread spectrum, so it's constantly changing
frequencies and doesn't put all of it's energy into one. Others, have a
channel selection choice in their configuration. You'll have to play around
with the setup on both the router and any wireless cards if you change any
of the configurations. (THEY MUST MATCH EXACTLY.) If you're using a D-Link
router & wireless card that have the "super-duper-speed-thing" turned on,
turn it off. That'll make reception better regardless of any interference.

Try to set the video repeater up first and make it as directional as
possible. If it's the kind with the little panel antennas, try to point the
sender at the receiver and vice-vera. If the sender has a little mast
antenna in addition to the panel, fold it down, but make sure that you can
still get a signal.

If you're traversing floors inside a house with the router, but not the
video (or vice-versa) consider putting one of the units on a high shelf and
its complement on the floor. If you're only working in one plane, then it's
just geography (not geometry <g>).

Figure out if there's a place to put your wireless access point so that it's
not directly in the path of the video repeater's signal. If it's a regular
wireless router, like a D-Link or a Linksys, chances are that it has one or
two little stubby antennas on the back. Unlike the video repeater antennas,
these aren't directional; they are omni-directional so they're going to
"spray" all over the place. You can prevent some of that, again, by
pointing the antennas to where you need the signal and by trying to avoid
overlapping with the video repeater's path. Again, depending on the type or
routers you have, a good healthy reset (and configuration reload) wouldn't
hurt every time you move something. I don't know it for fact, but have
heard that some of the 802.11 stuff is "smart" enough to avoid interference,
but may only look around when it's initialized.

If this gets you anywhere close, there are some directional antennas that
you can buy for the wireless routers that might help, but before I spent any
money, I'd consider looking at the newer wireless stuff that's on 5.8Ghz. A
whole new set of frequencies for everybody to muck up, but they'll be clean
for a while. Also, you might look for some older video repeaters (?eBay?).
IIRC, there were some that operated on 900Mhz and that shouldn't interfere.

Finally, as you're playing around with the antennas, if you find that you
can get the video signal lined up reasonably well, it does work to make a
little shield out of any kind of metal (aluminum foil worked for me). Wrap
this around the back of the panel antennas and let it stick out to protect
the sides. (It probably should be grounded, but I didn't worry about it and
it helped.) I never had to do it, but you could probably do the same thing
on the router's antennas with foil and tape.

thank you very much

No problem; Let us know how it all comes out.
