I recently purchased iWitness and one Nightwatch Low light camera.
Didn't really have any problems getting it to work.
These are some things that I had learned during my setup.
My current setup has the wireless camera and receiver approximately 30-35 feet away from each other
with little to some obstruction between the 2.
When I first set up the camera and receiver, both were in the same room
approx 12 feet from each other, with no obstruction. (proof of concept setup)
2) My wireless router is set to channel 11
Approximate Freq from wireless router"Channel 1 2399.5 MHz - 2424.5 MHz
Channel 2 2404.5 MHz - 2429.5 MHz
Channel 3 2409.5 MHz - 2434.5 MHz
Channel 4 2414.5 MHz - 2439.5 MHz
Channel 5 2419.5 MHz - 2444.5 MHz
Channel 6 2424.5 MHz - 2449.5 MHz
Channel 7 2429.5 MHz - 2454.5 MHz
Channel 8 2434.5 MHz - 2459.5 MHz
Channel 9 2439.5 MHz - 2464.5 MHz
Channel 10 2444.5 MHz - 2469.5 MHz
Channel 11 2449.5 MHz - 2474.5 MHz

B-2.434
C-2.453
D-2.473
4) My particular model Cordless phone according to the manual
operates in the 2402MHz to 2480MHz
5) I set both Vid Receiver and camera to Channel A
6) On initial setup in same room, quality of picture was very good,
adjustments on either the Receiver or Camera antenna would
result in vertical thick black lines.
7) I set the camera up in an outdoor position, and mounted the Vid Receiver w/
USB video adapter to the computer.
There is some obstruction between Camera and Video Receiver, and had to adjust
antennas on both Camera and receiver alternately to obtain optimum picture.
8 ) This worked fine for day one.
Day 2 there was a bit of rain, and I do have cover for the Camera (and the Power Supply is inside)
but noticed that when I turned the units on, all I got was a black screen.
I also forgot to replace the small rubber cap on the Channel selector on the Camera,
so it is possible that moisture got inside.
9) I switched Channels from A to B all the way to D on each unit
and still received the black screen.
I went back to A on both units (black screen) and then switched the
Video Receiver to Channel B. (Camera was still on A)
I then received a crisp picture.
Something was no longer aligned, but I figured it was just
an anomaly.
I then tried stepping down the Channels on the Receiver
as I also stepped down the Channels on the Camera (always 1 less than the Receiver)
and continued to get a crisp picture.
Receiver CameraB A
C B
D C
Later I noticed the same black picture, I switched both the Receiver and Camera back to A, and got the same crisp picture as before.
Not sure why both units were off on the actual frequency, but I thought it was interesting.
I also noticed in my environment that both units work fine on Channel A
when the cordless phone is On (talk)
But playing with the other channels that both units were set to;
B, C or D
that as soon as I pressed the Talk button on the Cordless Phone (dial tone)
I would get all vertical lines.
If I changed Channels on the phone while it was on, the picture quality returned.
So I guess the only time that you would potentially get interference from the
Cordless Phone is when it is on, but not off.
Right now, Channel A works fine with no interference from
wireless router or phone.
Well long write up, but I wanted to provide as much detail
about my experience as possible.
