hello

Over the weekend I tried out a visual thing using a wireless spycam, this one in fact. The artist had the camera hooked onto his ear, my laptop was hooked upto the receiver, and at my end we put a visual template over the feed.

It all worked perfectly during the soundcheck. but once showtime arrived I couldn't tune into the camera feed, does anyone know what may have happened? I was quite far away from the camera, about 20 metres, but as I said it worked fine before the doors opened. Could the PA interfere with the frequency once the sound gets turned up full?

Radio spectrum is planned out for different uses in different countries. In the US, there are some bands which are shared like 2.4GHz. Sometimes these are called ISM - instrumentation, scientific and medical.

Your camera probably works in that band. For one, the room probably filled with a few hundred people with bluetooth transmitters in their mobile phones (some phones have wireless LAN too), the resturant next door kicked on their microwave. In this same band, wireless landline handsets operate too.

I don't believe wireless mics or wireless lighting controls work in that band, but may in the future. Nothing else in the PA would interfere.

No guarantees on anything in the shared spectrum.
