CCTV would have been unknown in rural locations 10-15 years ago, they're everywhere now. They're also seen mounted on poles monitoring level crossings.
I've seen white plastic CCTV cameras, usually fixed to buildings or on a pole, that swivel around, probably with a motion sensor.
Open to correction but the P&T poles with the monkey-load of wires would be disused with +20 years, but remained in place for a while before arbitrary removal. I'd say they're all cut down by now, sometimes the lads just chop them down and leave them there rather than carting them away.
