Counter-surveillance sweep by Nationwide Investigations Group

In July 1994 the private detective agency Nationwide Investigations Group
conducted an electronic counter-surveillance
sweep of my parents home in London. They checked for radio transmitter devices,
and tested the telephone line for attached
bugs. They found nothing.

I am afraid that I was unsurprised at their not finding any evidence of covert
surveillance. It had been made very clear to me,
particularly during 1990-92, that audio, and almost certainly video,
surveillance of my parents home was taking place. But this
would not have been made quite so obvious unless the persecutors were confident
of their apparatus being undetectable using the
technology the police, or a private agency like Nationwide, would be using.

I dont know very much about the surveillance technology that has been used
against me, but I understand that devices can be built
which switch off on receiving a coded command, and may switch on again after a
counter- surveillance sweep has completed; that devices
may rapidly alter the frequency of transmission, "frequency-hopping"
devices which presumably cannot be detected in a sequential scan
of the sort employed by Nationwide; and of course "probe" microphones
can be inserted "through-the-wall", although I hesitate to
believe our neighbours would permit this.

We paid Nationwide £411.25 (including VAT) for the surveillance sweep,
which took them about an hour and a half to complete, using
a "Professional 5000 multi-scanner, CCL UHF scanner and Guideline
telephone tap detector." As I said above, I dont know very much
about these things, so I cant comment on the capabilities or otherwise of this
equipment. But clearly the "watchers" are using
technology which in 1994 was beyond the detection capabilities of a good
private detective agency.
