There are more uses for spy cams than just for nannies and babysitters. Many homeowners hire different contractors out to do work on their homes. Some of these included cleaning services, painters, electricians, and the like. These people are likely perfect strangers. Its discomforting wondering what these people are actually doing in your home while you are not there. Have things come up missing, has the work a contractor you hired taking longer than expected, and did the hired help actually come to your house at all?
A hidden camera can answer all these questions. You can keep track of exactly what has been going on in your home while you are at work or otherwise. In the event something has been stolen, you have proof. You can catch service employees doing other things, like watching TV or talking on the phone, instead of working. And you know that they have actually come to your home because you can see them there.
