Two guys, quite well dressed, knocked on our door on Devonshire road this evening. I spoke to them at length to see what they were about. They were quite pushy and wanted to come inside. They claimed to be offering a free ADT alarm to 20 houses on the street as a marketing ploy. The alarms were somehow monitored remotely but this required an ongoing fee.

They wanted to know quite a bit about my alarm, my neighbours, sensors, exits to the garden. Seemed a little suspect to be honest. No business card or other way of contacting them. I got the impression it was either quite an elaborate scheme to gather information for mass burglary, or a highly invasive and persistent form of doorstep selling.
