its IF Radiation i used to work at a satellite station and if you parked under a big dish the car alarm would always go off and your mobile wouldnt work i would assume that a IR CCTV camera probs uses the same signalls
best way to check for interfearence is to listen on long wave radio you can hear all sorts of interference wireless lans cctv mobile masts all sorts
bt just had the mtce contract for tetra i believe its really an o2 product i thought it worked on o2s gsm 900mhz range but used a CUG Closed user group ie police ambulance fire etc all have different sideband frequencies
The O2 Airwave (Tetra) has its own UHF Radio Network, nothing to do with 900 GSM, We (UK) where the first country on the Planet to have a full National Commercial Tetra Network (Dolphin Telecom) but the company went Tits Up and took most of the big Band 3 Networks down with it, about 5 yrs back.
The O2 Tetra Network, originally BT, was built independent of Dolphin, with a lot of help from the government and is still in use today.
My worry is, if the O2 Network falls over or is taken out, the Emergency Services have got a bit of a problem on their hands.
