My 16 year old son has been on a destructive path for awhile. We want to get security cameras inside and out as well as a security system. There are so many choices out there, with too many "sales people" it's overwhelming. Can you all recommend anything so that we can monitor our home, belongings and son when we are at work? Also do you know of any hidden cameras that actually work? Seems like all of the hidden ones have terrible reviews.
