HI ALL
Sorry for being touchy. I know it's an incredible situation, so much so, I always feel on the back foot when disclosing what's going on. It is hard to believe a couple could be so relentless and wasteful of their daily life resources in retirement and go to such lengths. I can see how their behaviour has conditioned and reinforced what they're trying to achieve. Her brother is a private investigator, their best friend is a retired CID sergeant and her son is either a solicitor or CID sergeant himself (according to their amplified comments over the hedge, anyway).
Closing the rear blind works. I actually said at a normal level in my own house "so, you can't do it now, can you?". The woman started screaming, shouting and balling at her husband, right on cue. Leaving the blinds open but disabling the wi-fi works also. I left the blinds open and enabled the wifi and they slammed on cue. I can't believe it??? I'll post a picture of said rear blind. Thing is, I can't see any camera pointing towards us, yet it's true they can appear as soon as I walk through the porch into the garden. We did have a group of three people view our house a few years back when we put it on the market. On their second viewing, two of them distracted me to return downstairs, one of them stayed upstairs, and when I ran up to see what he was doing, he had the bathroom window open and was signing at my neighbour who was stood on her lawn. All weird. One thing I do know is, I can't find or see any covert cameras on their land or mine?
Another strange one, but a couple of times in the pitch black, I've opened the rear blind to see a vertical panel of blue laser about a metre and a half square flash in the the pattern of broken glass or crazy paving on my patio. I just thought she was just using some kind of projector to wind me up, but I'm wondering if it's some kind of PIR detector. I know. All a bit sci-fi and incredulous, but all true (and at nearly 50, I work full-time and have no history of being crazy).
