Wireless CCTV problems (somewhat OT)

[JakeD <fgdfgdfg@xxxxxxxxxxx>]

I am trying to get to grips with an outdoor CCTV system, and I am new to
this technology. The system uses wireless cameras with IR LED's so it
should work in all lighting conditions. The DVR/receiver records to an SD
card. I actually have two almost identical systems, (different brands),
both bought new, yet both are giving me identical problems. The problem is
the motion detection feature built into the DVR/receiver.

The motion detection should cause the DVR to start recording only when it
dectects motion within a camera signal. However, I am experiencing constant
false triggers. If I set the motion detection sensitivity to a level where
I don't get the false triggers, then it is also not sensitive enough to
detect genuine movement. I suspect that the false triggers could be
wireless interference Could that be correct? Is this a common problem with
wireless CCTV systems?

One idea I had was to buy cameras that have motion detection built in. That
way, they would only transmit when they detect movement. There don't seem
to me many such cameras in existence though...

Any help or advice on this would be appreciated. And if anyone knows of a
more suitable forum for this question, please let me know!

Thank you,
