I know about USA Bugsweeps and I have tried to talk each of my clients into using them, but to no avail. And by no means do I advertise this service. The clients that request are typically from Infidelity Cases. Just looking for a handheld device to add to the checklist I already perform: Physical Inspection of all outlets, smoke detectors, confirm source of all wires and cords, identify the Amazon styled nanny cams, perform a IPv4 network scan, look for IR light detection, etc.
