Q&A: How can I improve my signal strength with a 900mhz wireless video baby monitor?
Question by dcigary: How can I improve my signal strength with a 900mhz wireless video baby monitor?
We recently purchased a wireless video baby monitor, and although it does work, there is significant interference in the signal due to my computer room with several PC’s and servers. Is there a way to boost this signal to compensate for the interference, or to set up a repeater for the signal?

If you have interference any sort of repeater or amplifier will only repeat and / or amplify the interference (noise) along with the desired transmission (signal). The problem is likely a signal to noise ratio problem and interference.
I presume you have done all you can with repositioning the units to make them closer together without getting closer to the interference. If not try that
With the electronic interference it becomes even more difficult to address. A baby monitor is nothing more than a microphone in the baby’s room and a speaker in the monitoring room linked wirelessly. Can you use a wired system? This may be your only practical choice. Perhaps a 5 MHz

if this is being used in uk, then any tampering is illegal.

its your noisy p.c.’s that is the problem try filtering them.
but exposing a young infant to radio waves is not recommended as high frequency causes protien molecules to spin and heat up, like in a microwave oven.
A hard wired amplifier with a microphone and loadspeaker would be the best method.
