Security gadgets come in a wide range of sophistication. It can be a simple dummy camera that emits light and rotates with tilt. It can be a sophisticated dome camera that produces some kind of video. Or, it can be a network of CCTV cameras that work full time to record all activities in the covered area. The difference is that the CCTV camera sends the recording to a video tape recorder or a computer.

The closed circuit television camera is a gadget that is in use in many public and residential locations. With new hazards facing our daily existence we don’t wonder anymore at the new applications of these cameras that we come to know about almost every day. Some stories are difficult to fathom, like the caregiver who was found to be punishing the infant she was supposed to be taking care of. Or the thief caught robbing clients of an internet café. In situations like this, we thank technology for giving us ways to keep us secure as we go about our daily chores.
