Digital spy cameras have the ability to record pictures and videos digitally. The difference that they have is that you do these recordings with the absence of tapes or films; plus, it can be hidden for the purpose of security and protection. Digital spy cameras are wireless and being run by batteries. No need to use a transmitter or receiver to record videos and shoot images. Videos can be recorded within a specified time length and downloading them to your computer afterwards is so easy. Compared to wireless spy cameras, digital spy cams are smaller and they are so handy that you can take them anywhere you want to.
