Security systems are more effective when installed before an incident :)
Yet reading more of the ADT training manual/videos, it is taught that the most common driver of SOHO alarm sales is an actual break-in, whether at the buyers property or a neighbors. Is this the case for video surveillience systems also, at least at the SOHO level? And where pre-existing systems are replaced with new ones, is a single negative event also the thing that drives it?
The question would be: Are most cameras systems purchased/replaced as a reaction to a specific negative incident?
