Popular belief is that since you own your home, you can wire it to record voice when you are not present. This is simply not true. Doing so can cost you big time. If you are caught doing this and someone makes a complaint, you can be charged with a felony. In New York, if you are part of the conversation, then you CAN record. If you leave the home and catch your spouse's phone conversation or a visiting friend, and they find out, you can be in deep trouble.
For example: You think your spouse or partner is cheating. So you wire your home or place recorders in the home. Your significant other waits for you to leave and calls the girlfriend/boyfriend. His/her end of the conversation is recorded by your devices. You capture all the "love you" kind of stuff. You approach that person with the evidence and that person is pissed about it. That person can now press charges and you will be arrested.
