CCTV comprises of a video camera linked to that of a recorder and monitor (The basic setup), with this you will be able to unobtrusively watch events taking place whether that be live or alternatively recorded and viewed at a later date. There are covert cameras available on the market that are smaller than a matchbox and thinner than a credit card. These types of covert cameras can be placed almost anywhere to observe an area/targets activities. Not only can you buy these cameras as standalone devices to install into whatever you please. You can also purchase a vast array of cameras already covertly installed into everyday objects such as Radio alarm clocks, Smoke detectors, plug sockets, air fresheners and much more. CCTV produces either colour or Black and white (Monochrome) images. The colour cameras can be more pricey however the monochrome cameras usually produce a better quality image especially in low light conditions.
