No better time exists for a complete and full spy camera system than right now. Many people say that a hidden camera system is not necessary. They believe costs outweigh the benefits. Now if you are living on a quarter acre lot with a 1500 square foot house, then installing 20 cameras is ridiculous. The cost most definitely outweighs any benefit.
A complete spy camera system has the following security tools and gadgets: spy cameras to be hidden, a PC or DVR for recording, playback, and storage, a wireless transmitter, and a wireless receiver. Now immediately when you buy a wireless spy camera, the transmitter and receiver come with the camera. The number of cameras you use depends on exactly what kind of spy coverage you want. You can buy simple CCTV wireless cameras that are not hidden, but meant to be seen by intruders so they know they are seen.
