'Phone watch' scam in county?

I bumped into a neighbour this evening and during the catch-up, she told me about two young-ish women who called to her house last week trying to sell her what they called a 'phone watch' burglar alarm.

They gave her a very hard sell by the sounds of it, saying she needed to sign up now on the spot coz they might not be able to call back, then they cut the price dramatically, etc.

The neighbour is a polite woman so she listened for a while and then asked them to go, saying she'd think about it.

She found out later that another 'phone watch' salesman had called to her son's house at the same time, but as her son was heading out he asked yer man for some brochures, or flyers, or something he could read later. But this salesman had neither flyers nor a business card nor any contact number.

Now, to me, this smells of a scam. Has anyone else heard of these 'phone watch' people calling to homes in the county? The above visit happened Wed/Thurs evening last week, around 5.30 in the evening, a few miles from Kilmac.

Is this something people should be wary of? Or does anyone know if genuine, but very pushy, Eircom Phone Watch people were in the area last week?
